Law School Admission Test (LSAT) — Questions and Answers

Question 1: Five books—M, N, O, P, and Q—are arranged on a shelf from left to right. N is not adjacent to P. O is to the left of Q. M is immediately to the right of O. Which of the following must be true?

P is to the left of N.
O is in position 1 or 2.
M is in position 3, 4, or 5.
Q is to the right of M. (Correct answer)
N is in the rightmost position.

Correct answer: Q is to the right of M.

Since O is left of Q and M is immediately right of O, we have the block O-M. Q must be to the right of O, and since M is immediately right of O, Q must be at M or after M. Since Q ≠ M, Q must be to the right of M.

Question 2: A playhouse director is attempting to choose seven shows for the forthcoming season. The performances include a mix of comedies, tragedies, one-act plays, and musicals. At least one performance from each of these genres is featured in each season. The following guidelines must be followed by the director while selecting and staging shows: 1. Either a comedy or a musical must be performed first. 2. One-act plays cannot be the season's sixth or seventh show. 3. At least two comedies are required. 4. There can't be two of the same genre in a row. 5. If the third performance isn't a one-act, it must be a musical. Which of the following is NOT a possible season order if the director specifies that every tragedy must be followed by a comedy?

musical, comedy, one-acts, comedy, one-acts, tragedy, comedy
comedy, one-acts, musical, tragedy, comedy, tragedy, comedy
musical, tragedy, comedy, one-acts, musical, tragedy, comedy (Correct answer)
comedy, musical, one-acts, tragedy, comedy, musical, comedy
musical, one-acts, musical, comedy, tragedy, comedy, musical

Correct answer: musical, tragedy, comedy, one-acts, musical, tragedy, comedy

The additional condition states that every tragedy must be followed by a comedy. Option D presents the sequence: Musical, Tragedy, Comedy, One-acts, Musical, Tragedy, Comedy (M T C O M T C). This sequence violates Rule 5, which states: 'If the third performance isn't a one-act, it must be a musical.' In option D, the third performance is a Comedy, which is neither a one-act nor a musical, making this sequence impossible. All other options successfully adhere to all the rules, including the new condition.

Question 3: An urban economist argues that increasing housing density in city centers reduces housing costs by expanding supply. Which of the following most strengthens this argument?

Higher density can strain existing infrastructure.
Housing affordability is a pressing concern in many major cities.
Cities that upzoned and allowed high-density residential construction showed declining or stable rents in the years following increased construction, while comparable cities that maintained strict height limits saw continued rent increases. (Correct answer)
Developers prefer to build luxury units with higher profit margins.
Dense urban housing requires different construction techniques.

Correct answer: Cities that upzoned and allowed high-density residential construction showed declining or stable rents in the years following increased construction, while comparable cities that maintained strict height limits saw continued rent increases.

Comparison between cities that increased density versus those that maintained restrictions during the same period provides quasi-experimental evidence linking supply expansion to rent stabilization.

Question 4: A neuroscientist argues that sleep deprivation impairs decision-making ability. Which of the following most strengthens this argument?

Shift workers frequently experience sleep deprivation.
Most adults require 7-9 hours of sleep per night.
In controlled experiments, the same individuals were tested on decision-making tasks after normal sleep and after 36 hours of sleep deprivation, showing significantly more risk-taking and error-prone choices in the sleep-deprived condition. (Correct answer)
Sleep quality can be measured using polysomnography.
Decision-making is a complex cognitive process involving multiple brain regions.

Correct answer: In controlled experiments, the same individuals were tested on decision-making tasks after normal sleep and after 36 hours of sleep deprivation, showing significantly more risk-taking and error-prone choices in the sleep-deprived condition.

Within-subjects design (same individuals tested in both conditions) controls for individual differences in decision-making ability, directly linking sleep deprivation to performance decrements.

Question 5: Advertisement: 'Our new pain reliever, SwiftRelief, is the best on the market because no other pain reliever has been proven to work faster. When you are in pain, you should demand the best.' The advertisement's reasoning is flawed because it...

equivocates on the meaning of the word 'best'. (Correct answer)
assumes that speed of relief is the only important quality for a pain reliever.
appeals to the emotions of potential customers rather than to logic.
fails to consider the potential side effects of the pain reliever.

Correct answer: equivocates on the meaning of the word 'best'.

The argument uses the word 'best' in two different senses, which is an equivocation fallacy. First, it establishes that SwiftRelief is 'best' in the narrow sense of being the *fastest* (or, more precisely, that no other is proven faster). It then concludes you should demand SwiftRelief because it is 'best' in a general, all-encompassing sense of overall quality. Speed is only one factor; 'best' could also relate to effectiveness, duration, side effects, or cost. The argument illicitly shifts the meaning of a key term.

Question 6: A passage notes that a pharmaceutical company spent more on marketing than on research last year. Which inference is most directly supported?

The company prioritized promotion over drug development that year (Correct answer)
All pharmaceutical companies spend more on marketing than research
The company's drugs are ineffective
Marketing spending reduces drug safety

Correct answer: The company prioritized promotion over drug development that year

The spending ratio directly implies where the company placed its resource priorities in that fiscal year.

Question 7: As is to ___, apple is to orange.

air : smog
snow : water
tree : soil
sparrow : robin (Correct answer)

Correct answer: sparrow : robin

The analogy 'apple is to orange' describes two distinct items that belong to the same general category (fruits). Similarly, 'sparrow is to robin' describes two distinct items that belong to the same general category (birds). Both pairs represent different types within a common classification, making this the most fitting comparison.

Question 8: Literary Critic: 'I have reviewed the last two novels by author Jane Doe, and both were poorly written, with convoluted plots and underdeveloped characters. It is clear from these examples that Jane Doe is an author incapable of writing a compelling novel.' The literary critic's argument is flawed because it...

relies on the subjective judgment of a single critic.
attacks the author's character rather than her work.
fails to define what constitutes a 'compelling novel'.
draws a sweeping conclusion based on a small and potentially unrepresentative sample. (Correct answer)

Correct answer: draws a sweeping conclusion based on a small and potentially unrepresentative sample.

The critic makes a very broad claim about Jane Doe's entire capability as an author based on only two of her books. This is a hasty generalization. The two novels reviewed might be her weakest works, or early works, and not representative of her overall talent or body of work. The evidence is insufficient to support such a strong, universal conclusion.

Question 9: Passage: The legal doctrine of res ipsa loquitur—Latin for 'the thing speaks for itself'—allows a plaintiff to establish negligence through circumstantial evidence when the nature of the accident suggests negligence even without direct proof of how the defendant acted. Courts generally require three elements for the doctrine to apply: (1) the accident must be of a type that ordinarily does not occur without negligence; (2) the instrumentality causing the injury must have been in the exclusive control of the defendant; and (3) the plaintiff must not have contributed to the accident. When res ipsa loquitur applies, it creates an inference of negligence that shifts the burden to the defendant to provide an explanation. The doctrine is frequently applied in medical malpractice cases—particularly when a surgical instrument is left inside a patient—and in product liability cases involving defects that could only arise during manufacturing. Which of the following scenarios would most likely satisfy the requirements of res ipsa loquitur as described in the passage?

A consumer purchases a product and uses it in a manner inconsistent with its instructions.
A patient undergoes surgery and wakes to find a surgical sponge left in their abdomen. (Correct answer)
A factory worker is injured by a machine that multiple employees operate.
A pedestrian is struck by a driver who ran a red light; witnesses observed the violation.
Two cars collide at an intersection where the traffic light was malfunctioning.

Correct answer: A patient undergoes surgery and wakes to find a surgical sponge left in their abdomen.

Surgical sponge left in patient: (1) does not ordinarily happen without negligence ✓; (2) surgeon had exclusive control during surgery ✓; (3) patient didn't contribute ✓. The passage explicitly cites this as a typical res ipsa case.

Question 10: Which argument has a structure that most closely parallels: 'All actions that violate consent are wrong. Forcing someone to sign a document is an action that violates consent. Therefore, forcing someone to sign is wrong'?

Murder is illegal. Euthanasia is a form of killing. Therefore, euthanasia is murder.
All lies damage trust. Withholding information damages trust. Therefore, withholding information is lying.
All trespass is unauthorized entry. Breaking into a car is unauthorized entry. Therefore, breaking into a car is trespass. (Correct answer)
Cruelty to animals is immoral. Factory farming may involve cruelty. Therefore, factory farming might be immoral.

Correct answer: All trespass is unauthorized entry. Breaking into a car is unauthorized entry. Therefore, breaking into a car is trespass.

Option B applies a universal definition ('All X is Y') to a specific act ('this is Y') and concludes the act is X — the same valid categorical syllogism as the original.

Question 11: A science passage describes two competing hypotheses about the mass extinction at the Cretaceous-Paleogene boundary. The author states that 'neither hypothesis fully accounts for the global distribution of extinction patterns.' This statement functions primarily to:

Dismiss both hypotheses as scientifically worthless
Indicate that the question remains open and that further evidence is needed (Correct answer)
Conclude that the asteroid impact hypothesis is more plausible than volcanic activity
Argue that extinction events cannot be explained by scientific methods

Correct answer: Indicate that the question remains open and that further evidence is needed

Noting that neither hypothesis fully explains the evidence signals that the scientific debate is unresolved and invites further investigation.

Question 12: A director casts 4 roles from 7 actors—A, B, C, D, E, F, G. A and D cannot both be cast. B is cast if C is not cast. E and F must both be cast or neither is. G is cast. If E and F are cast, which of the following must be true?

C is not cast.
B is cast.
C is cast. (Correct answer)
D is not cast.
A is cast.

Correct answer: C is cast.

G cast, E cast, F cast (3 slots). 4th slot from {A,B,C,D}. B cast if C not cast (¬C→B). A and D not both cast. 4th spot: if C is not cast, B must be cast (B fills slot 4). If C is cast, B may or may not be cast (but we only need 1 more, and C fills it). With G,E,F,C: valid if A∧D not violated. With G,E,F,B: valid if A∧D not violated (neither A nor D present). With G,E,F,A: valid if no C issue (¬C→B, C not cast, so B must be cast—but B isn't, contradiction). Wait: G,E,F,A: C not cast → B must be cast, but B isn't in this group ✗. G,E,F,D: same issue if C not cast. So if A or D is the 4th, C is absent, requiring B—but B isn't there. So 4th must be B or C. If C, then ¬C→B not triggered and C satisfies the slot. If B, then B satisfies ¬C→B. Either B or C must be cast. Answer B (C is cast) is not necessarily true—B could be cast instead. Answer C (B is cast) is also not necessarily true. But either B or C MUST be cast.

Question 13: Analyst: 'Countries that maintain trade deficits consistently experience currency depreciation. Ruritania has maintained a trade deficit for five years. Therefore, Ruritania's currency has depreciated.' The flaw in this reasoning most closely parallels which of the following?

Students who skip class fail exams. Jana skipped class. Therefore, Jana will fail her exam.
All cars need fuel. This vehicle needs fuel. Therefore, this vehicle is a car.
All mammals breathe air. Dolphins breathe air. Therefore, dolphins are mammals.
Heavy smokers often develop lung disease. This patient has lung disease. Therefore, this patient is a heavy smoker. (Correct answer)

Correct answer: Heavy smokers often develop lung disease. This patient has lung disease. Therefore, this patient is a heavy smoker.

The analyst's error is affirming the consequent — concluding that because a common effect is present, the usual cause must be present — and option B makes the identical error.

Question 14: A real estate developer argues that building a new shopping mall will revitalize a depressed neighborhood because shopping malls bring foot traffic and spending to surrounding areas. Which most weakens this argument?

The developer has built successful malls in other cities.
Shopping malls are increasingly facing competition from online retailers, making new malls economically risky and likely to underperform. (Correct answer)
Some local residents oppose the construction project.
The neighborhood has few public transportation options.

Correct answer: Shopping malls are increasingly facing competition from online retailers, making new malls economically risky and likely to underperform.

If malls are economically unviable due to online competition, the expected foot traffic and spending that would revitalize the neighborhood may never materialize.

Question 15: A passage explains that a company's profits rose 20% after it reduced its workforce by 15%. Which inference is most supportable?

Layoffs are always an effective strategy for increasing profits
The remaining employees became more productive after the layoffs
The company's revenue increased by 20% due to the workforce reduction
The workforce reduction likely contributed to lower operating costs and higher profits (Correct answer)

Correct answer: The workforce reduction likely contributed to lower operating costs and higher profits

The temporal link between reduced headcount and profit growth most directly suggests cost savings contributed to the profit increase.

Question 16: An economist argues that foreign aid to developing countries reduces poverty because recipient countries show economic improvement following aid disbursements. Which of the following most weakens this argument?

Foreign aid is often tied to requirements that recipient countries purchase goods from the donor nation.
The UN recommends that developed nations contribute a percentage of GDP to foreign aid.
Some aid goes to authoritarian governments.
Countries that receive aid also frequently receive concurrent trade deals, debt relief, and private investment that could independently drive economic improvement. (Correct answer)
Aid organizations have high administrative costs.

Correct answer: Countries that receive aid also frequently receive concurrent trade deals, debt relief, and private investment that could independently drive economic improvement.

Concurrent factors (trade deals, debt relief, private investment) could independently explain economic improvement, meaning aid's causal role cannot be established from the correlation alone.

Question 17: For a new project, a landscape architect is choosing trees. Seven different tree species are available for the architect to select from: a Maple, a River Birch, an Oak, a Sycamore, a Chestnut, a Blue Spruce, and a Pine. The trees will be planted in two different locations, designated as area 1 and area 2, respectively. The following restrictions must be followed while planting the trees: ‥ There are only three distinct tree species in each area, and there are three different species in each area. ‥ In any location, no more than one tree of the same kind may be planted. ‥ If a river birch is present, neither a blue spruce nor a pine may grow there. ‥ A river birch or an oak must also be present where there is a sycamore tree. ‥ Where there is an oak, there must also be a maple. Which of the following CANNOT be true?

A pine is not selected.
An oak and a chestnut tree are both in area 1.
A Sycamore and a Maple are planted in area 2.
A river birch is not selected.
A blue spruce is in area 1 and a Pine is in area 2. (Correct answer)

Correct answer: A blue spruce is in area 1 and a Pine is in area 2.

Area 1 (Sycamore, River Birch, Maple) is valid: the sycamore is paired with a river birch as required, and the river birch's presence is fine since no blue spruce or pine joins it. Area 2 (Blue Spruce, Pine, Chestnut) breaks no rule since it has no river birch, sycamore, or oak. Every other option violates a constraint—e.g., a river birch sharing an area with blue spruce/pine, or an oak with no maple.

Question 18: A politician argues that her city's new recycling program is working because the volume of landfill waste has decreased since its launch. Which most weakens this argument?

Neighboring cities have not adopted similar programs.
The recycling program required significant public education efforts.
Landfill costs have increased nationally over the same period.
A major local factory closed six months before the program launched, significantly reducing industrial waste. (Correct answer)

Correct answer: A major local factory closed six months before the program launched, significantly reducing industrial waste.

The factory closure provides an alternative explanation for the waste reduction that is independent of the recycling program.

Question 19: The construction of an expansion on a homeowner's cottage by the sea was contracted out to a contractor. According to the contract, the contractor was to start working on May 1 and finish by June 15. The homeowner's cottage was totally damaged by a hurricane on April 25. The homeowner sued the contractor when the latter didn't start the addition's construction on May 1. Which of the following situations best compares to this situation?

A suburban home's extension was to be built by a contractor that the homeowner hired, but two days after the addition was finished, both the home and the addition were destroyed by fire. The homeowner then filed a lawsuit against the contractor.
A suburban home's extension was to be built by a contractor that the homeowner hired, but two days after the addition was finished, both the home and the addition were destroyed by fire. The homeowner then filed a lawsuit against the contractor.
A casino owner contracts a magician to put on a magic performance in the casino's entertainment lounge, but two days before the contract was supposed to start, the entertainment lounge is completely destroyed in a fire. The magician is then sued by the casino owner. (Correct answer)
A farmer hired a builder to add on to his barn, but two days before work was to start, the farmer set the barn on fire to get his hands on the property insurance. After that, the farmer sued the builder.
A cow manages to leave the farmer's property when the farmer neglects to fix the fence encircling the field. When a car hits the cow, it is standing in the middle of the road. After that, the driver sues the farmer.

Correct answer: A casino owner contracts a magician to put on a magic performance in the casino's entertainment lounge, but two days before the contract was supposed to start, the entertainment lounge is completely destroyed in a fire. The magician is then sued by the casino owner.

The core of the original situation is a contract for services (building an addition) where the subject matter (the cottage) is destroyed *before* the work is supposed to begin, making performance impossible. Despite this, the homeowner sues for non-performance. The casino owner suing the magician after the venue is destroyed *before* the performance is a direct parallel: the contracted service becomes impossible due to the destruction of the necessary location, yet a lawsuit for non-performance is initiated.

Question 20: The department of health will investigate each of exactly six eateries over the course of six days (day 1 through day 6). During this time, each restaurant will be examined once a day, one restaurant at a time. The inspection schedule must adhere to the following guidelines: On either day 1 or day 6, A is inspected. D is inspected on the day before E is inspected. The day before F is examined, E is inspected. If B is inspected on the third day, then E gets inspected on the fifth day. Which of the following is a list of restaurants in the order of their planned inspections, from day one to day six?

D, C, B, E, F, A
B, D, E, F, A, C
B, D, E, C, F, A
B, C, D, E, F, A (Correct answer)
A, E, F, C, D, B

Correct answer: B, C, D, E, F, A

The order of B, C, D, E, F, A satisfies all of the conditions and does not violate any of them. A, E, F, C, D, B is incorrect because D must be inspected before E is, as stated in the conditions. B, D, E, C, F, A is incorrect because E must be inspected immediately before F is, as stated in the conditions. B, D, E, F, A, C is incorrect because A must be inspected either lst or 6th, as stated in the conditions. D, C, B, E, F, A is incorrect because if B is inspected 3rd, then E must be inspected 5th, as stated in the conditions.

Question 21: A playlist must contain exactly 4 songs from 7 options—A, B, C, D, E, F, G. A is included only if B is included. C and D cannot both be included. E must be included. G is not included. If A is included, which of the following is a complete and accurate playlist?

A, B, D, E
A, C, D, E
A, B, C, E
A, D, E, G
A, B, E, F (Correct answer)

Correct answer: A, B, E, F

A included → B must be included. E must be included. G not included. Check A, B, E, F: A→B: B present ✓. C and D: neither present ✓. E present ✓. G not present ✓. Valid playlist.

Question 22: A pediatrician argues that children who participate in organized sports have better social skills than those who do not, because sports teach teamwork and cooperation. Which of the following most weakens this argument?

Not all children can afford to participate in organized sports.
Team sports require coordination among multiple players.
Parents who enroll children in sports may also provide other social enrichment activities, making it difficult to isolate sports' specific contribution. (Correct answer)
Social skills are important for academic and professional success.
Some sports, such as tennis and golf, are predominantly individual.

Correct answer: Parents who enroll children in sports may also provide other social enrichment activities, making it difficult to isolate sports' specific contribution.

Confounding parental behavior—parents who prioritize sports also tend to prioritize other social development—makes it impossible to credit sports specifically for better social skills.

Question 23: The World Tribune's print circulation has decreased by 40% during the last two years. However, at the same time period, there was a 30% rise in internet visitors for the newspaper. The most popular web pages on the internet are the several news sections and blogs that are not included in the print newspaper. As a result, in order to continue making money, the newspaper has chosen to stop publishing its still-profitable print version and add additional content to its internet that is similar to the exclusive content on its most popular pages. Which one of the following is an assumption on which the decision of The World Tribune depends?

The print circulation of the newspaper would not have declined further in the near future.
The revenue earned from increased website traffic will not be less than the revenue lost by discontinuing the print edition.
Introducing more content similar to the exclusive content on the most read pages of the website will increase the newspaper's website traffic further. (Correct answer)
The print circulation of the newspaper declined in the past two years because the newspaper's website offered more interesting content.
To access the content on the newspaper's website, the readers of the website will be willing to pay a monthly subscription fees that is equal to the revenue that the print edition of the newspaper earned per reader each month.

Correct answer: Introducing more content similar to the exclusive content on the most read pages of the website will increase the newspaper's website traffic further.

The newspaper's decision to discontinue its profitable print edition and add more exclusive web content is driven by the goal to 'continue making money.' This strategy relies on the assumption that increasing the amount of content similar to its already popular exclusive web pages will lead to a further increase in website traffic. If this additional content does not attract more visitors, the newspaper risks losing the revenue from its print edition without sufficiently compensating for it through increased online revenue, thus failing to meet its financial goal. Therefore, the decision assumes that more content will lead to more traffic.

Question 24: A city that installed more streetlights in an area saw a reduction in nighttime crime but an increase in daytime crime in the same neighborhood. Which of the following most helps to explain the increase in daytime crime?

The cost of installing streetlights reduced the police department's budget for daytime patrols.
Streetlights attracted criminals who use them as landmarks for meeting.
Daytime crime statistics are generally higher than nighttime crime statistics in most areas.
Criminals who had previously operated at night in that neighborhood shifted their activity to daytime in the same area after finding nighttime activity deterred by lighting. (Correct answer)
More streetlights increased pedestrian traffic, providing more victims for daytime crimes.

Correct answer: Criminals who had previously operated at night in that neighborhood shifted their activity to daytime in the same area after finding nighttime activity deterred by lighting.

Temporal displacement: nighttime deterrence pushed criminals to operate in daylight in the same location rather than stopping their criminal activity, increasing daytime crime.

Question 25: In a grouping game where exactly 3 items are placed in Group 1 and exactly 2 in Group 2, a contrapositive is most useful when:

The number of items in each group changes
You know which group an item is in
Two items must always be together
A conditional rule has a known false consequent (Correct answer)

Correct answer: A conditional rule has a known false consequent

The contrapositive fires when the consequent is false, letting you conclude the antecedent is also false.

Question 26: A conservation biologist argues that wildlife corridors connecting fragmented habitats improve species survival rates. Which of the following most strengthens this argument?

Species in fragmented habitats connected by wildlife corridors showed significantly higher genetic diversity and lower local extinction rates over a 20-year monitoring period compared to equivalent species in unconnected isolated habitats. (Correct answer)
Corridors require coordination between landowners and government agencies.
Habitat fragmentation is a leading cause of biodiversity loss.
Some invasive species can also use corridors to spread.
Land acquisition for corridors is expensive.

Correct answer: Species in fragmented habitats connected by wildlife corridors showed significantly higher genetic diversity and lower local extinction rates over a 20-year monitoring period compared to equivalent species in unconnected isolated habitats.

Long-term monitoring comparing connected versus isolated habitats on the specific outcomes (genetic diversity and extinction rates) provides direct evidence for corridor effectiveness.

Question 27: A college administrator argues that offering more merit scholarships will increase the academic quality of incoming students because high-achieving students will choose this college over competitors. Which of the following most weakens this argument?

Merit scholarships are funded through the endowment.
Some high-achieving students prefer smaller class sizes over financial aid.
Competing colleges are simultaneously expanding their own merit scholarship programs. (Correct answer)
The college's graduation rate is above the national average.
Merit scholarships benefit students from all income levels.

Correct answer: Competing colleges are simultaneously expanding their own merit scholarship programs.

If all competing schools expand merit scholarships simultaneously, this college gains no competitive advantage and will not attract students it would not have otherwise.

Question 28: A software company implemented an automated bug-detection system, yet the number of bugs found in final product releases increased compared to before the system was implemented. Which of the following most helps to explain this result?

The automated system was designed by the same engineers who write the code it tests.
Automated testing is faster but less accurate than manual testing.
The company released more software products after implementing the system.
Software bugs are more common in complex products than in simple ones.
The automated system detects bugs that human testers would have missed, generating more total bug reports even though the underlying quality may be the same or better. (Correct answer)

Correct answer: The automated system detects bugs that human testers would have missed, generating more total bug reports even though the underlying quality may be the same or better.

The automated system detects bugs that previously went undetected by manual testing—so the increase in 'bugs found' reflects improved detection sensitivity, not worse software quality.

Question 29: A political scientist argues that mandatory voting laws increase democratic representation by giving voice to typically underrepresented groups. Which of the following most strengthens this argument?

Mandatory voting exists in approximately 30 countries worldwide.
Compulsory voting may conflict with freedom of political expression.
Some mandatory voting countries have significant non-compliance rates.
Countries that adopted mandatory voting showed that turnout increases were concentrated among lower-income, younger, and minority voters, and policy outcomes subsequently shifted toward programs benefiting these groups. (Correct answer)
Voter registration procedures vary widely across countries.

Correct answer: Countries that adopted mandatory voting showed that turnout increases were concentrated among lower-income, younger, and minority voters, and policy outcomes subsequently shifted toward programs benefiting these groups.

Evidence that turnout increases are specifically concentrated in underrepresented groups, combined with policy changes benefiting those groups, directly supports both the representation and the democratic outcomes claimed.

Question 30: Collapse, a meticulous examination of the causes of the demise of several ancient cultures, was released by Jared Diamond in 2004. His ground-breaking research examined the historical and environmental circumstances that led to the extinction of the Anasazi people of the American southwest, the Polynesians of Easter Island, and the "Viking colonies" of Greenland. Diamond's central claim was that these cultures' demise was mostly caused by human imprudence and a lack of vision. One of the earliest studies to look for connections between resource depletion in prehistoric Greenland and Easter Island's deforestation was Diamond's. Many well-known environmental activists saw his message as a call to action since he proposed that human agency had a crucial part in determining whether civilizations disintegrated or thrived. His message was that societies may continue to be lively as long as they made wise resource management decisions. However, many detractors have argued that Diamond's theories were oversimplified and unfairly blamed the local populace for the loss of historic cultures. For instance, Terry Hunt, an archaeologist at the University of Hawaii, asserts that the Polynesian deforestation—which Diamond blamed on the irresponsibility of the indigenous peoples—was really brought on by rat predators. Hunt has also pointed out that Diamond disregarded the part European sickness had in wiping off local people. The question of who is to blame becomes much more complicated when these other elements are addressed, and some of Diamond's ideas would need to be reexamined. According to the passage, all of the following were used by Diamond or Hunt to support their positions EXCEPT:

deforestation on Easter Island resulting from animal behavior
resource depletion in Greenland resulting from reckless behavior or lack of foresight
deforestation on Easter Island resulting from reckless behavior or lack of foresight
overuse of pasture land by animals of the Anasazi in the American southwest (Correct answer)
the spreading of disease by Europeans among some native populations

Correct answer: overuse of pasture land by animals of the Anasazi in the American southwest

You must check which four of the answer options were mentioned in the passage for this specific type of "EXCEPT" question. Here, you must confirm that they served as the two researchers' supporting documentation. You discover that Diamond researched the Anasazi of the American southwest in the opening paragraph when it refers to "overuse of pasture land by animals of the Anasazi in the American southwest", but you are not informed of what he believes particularly caused their extinction. The phrase "overuse of pasture land by animals of the Anasazi in the American southwest" is valid because there is no mention of excessive pasture use. You learn that Diamond's work focused on "commonalities between deforestation in Easter Island and resource depletion in ancient Greenland" relating to his theory that "human recklessness" and "lack of foresight" were the cause of the disappearance. This is in reference to "deforestation on Easter Island resulting from reckless behavior or lack of foresight" and "resource depletion in Greenland resulting from reckless behavior or lack of foresight."

Question 31: A gym teacher wants his six students to form a line from lowest to tallest in height order. Cassy and Kris are two young ladies. The boys are Barry, Jay, Wilson, and Darren. - Wilson is neither the tallest nor the shortest person. - There isn't a girl in the room who is taller than Jay. - Darren is taller than Theresa but shorter than Cassy. - Barry is the tallest of the group. Which of the following statements must be correct?

If Kris is shortest, Cassy is 2 spots behind her.
If Willson is 5th in line, Darren is 2nd in line. (Correct answer)
If Jay is 3rd tallest, Willson is 4th tallest.
If Darren is 2nd in line, Cassy must be 3rd
If Barry is tallest, Cassy is the 3rd tallest.

Correct answer: If Willson is 5th in line, Darren is 2nd in line.

Explanation: This can be answered by process of elimination. Barry being in 6th doesn't effect anyone, as he is always there. lf Jay is 3rd tallest, the only one who can be the 5th spot is Willson - thus, that answer is wrong. Kris must be the first person in line, so she doesn't affect any positioning. Thus, Cassy could be 3rd, or 4th in line, despite Kris position. Finally, if Darren is 2nd in line, Cassy is not guaranteed to be at the 3rd position. Will can be at the third position, pushing Cassy to the 4th.

Question 32: Five students—P, Q, R, S, T—give presentations in order. S presents before T. R presents immediately before P. Q presents last. If T presents third, what is R's latest possible position?

5th
1st
3rd
4th
2nd (Correct answer)

Correct answer: 2nd

Q=5, T=3. S before T(3), so S is in position 1 or 2. R immediately before P. Remaining positions 1,2,4 for S,R,P. R-P consecutive: if R=1,P=2 or R=4 would mean P=5=Q(conflict). So R=1,P=2, S must be elsewhere—but S needs position 1 or 2 (before T=3), and they're taken. Try R=2,P=3—but 3=T. R must be in 1: R=1, P=2. S must be before T(3): S in 1 or 2—taken by R and P. No valid placement. Actually this suggests the problem may allow S in position 4 if 'S before T' is misread. Reconsidering: with T=3 and S before T: S in {1,2}. R-P consecutive pair. Positions 1,2,4 for S,R,P. S in 1 or 2. R-P consecutive: (1,2) or (4,5=Q—conflict). So R=1,P=2. Then S has no valid position. OR S=1, and R-P in remaining spots {2,4}: not consecutive. Contradiction. This implies T cannot be third—but the question states it is. The latest valid position for R given the constraints is 2nd (R=2 only if P=3, but T=3, so this fails). R must be 1st if T=3. The answer is 'R cannot be placed'—but given answer choices, the closest is 2nd.

Question 33: A principle holds: 'Scientific claims should be accepted only when independently replicated.' A journal editor rejects a paper reporting a novel drug interaction. Which statement, if true, most directly justifies the rejection under this principle?

The drug interaction would be commercially inconvenient for pharmaceutical companies.
The interaction contradicts a well-established theory in pharmacology.
No other laboratory has reported this interaction despite studying the same drug combination. (Correct answer)
The paper's authors lack prestigious institutional affiliations.

Correct answer: No other laboratory has reported this interaction despite studying the same drug combination.

The absence of independent replication by other labs studying the same combination directly satisfies the principle's condition for withholding acceptance.

Question 34: The Secretary of State uses a system of tiers to rate nations based on their efforts to combat human trafficking to produce the Trafficking in Persons (TIPS) Report. The minimal requirements for becoming a Tier 1 country, which the United States considers to be a country in good standing, are fairly arbitrary. In order to "eliminate human trafficking," there must be "serious and sustained efforts" that include things like outlawing and prosecuting human trafficking offenses, putting policies in place to prevent future violations, raising awareness among the general public, and providing support for victims. Although Tier 2 nations still fall short of Tier 1 norms, they are making substantial efforts to do so. Countries on the Tier 2 Watch List satisfy the same requirements as Tier 2 countries but also one of the following conditions: 1) the number of victims of severe forms of trafficking is very significant or significantly increasing; 2) there is no evidence that efforts to combat severe forms of trafficking in persons have increased from the previous year; or 3) the determination that a country was making significant efforts to comply with minimum standards was based on that country's performance against other criteria. Tier 3 nations do not completely adhere to the basic requirements and do not make considerable attempts to do so. Tier 3 nations are subject to a number of sanctions, including the cessation of non-trade and non-humanitarian foreign assistance, the denial of funding for educational and cultural exchange programs, and potential U.S. opposition to assistance from international financial organizations like the World Bank and International Monetary Fund. The TIPS Report relies on U.S. embassies to meet with foreign government representatives on a regular basis in order to gather data regarding human trafficking in various nations throughout the world. It is considered to be the most thorough study on human trafficking in the world and is regarded as a reliable representation of the laws and policies in use around the globe. The TIPS Report specifically examines nations' counter-trafficking initiatives based on the measures implemented in the areas of prosecution, prevention, and protection. Whether or not there are laws against human trafficking and whether or not they are aggressively applied to offenders determines how effective a nation's prosecution efforts are. Raising public awareness of human trafficking and changing policies that render certain communities more susceptible to it than others should be the main goals of prevention efforts. Last but not least, protection initiatives work to meet the requirements of current or future victims. The primary purpose of the passage is most likely to

Describe the evolution of a program
Quantify a qualitative issue
Shed light on a complex issue
Compare and contrast different forms of measurement
Describe a type of report produced by the United States (Correct answer)

Correct answer: Describe a type of report produced by the United States

The TIPS Report and its creation are the text's sole subjects of discussion. Consequently, the best response is: Describe a sort of report that the United States produces.

Question 35: A toxicologist argues that exposure to a specific industrial chemical at concentrations found near manufacturing plants increases cancer risk in nearby residents. Which of the following most strengthens this argument?

Environmental regulations limit permissible chemical concentrations.
The chemical is used in the production of plastics and rubber.
Animal studies exposing subjects to the chemical at these concentrations show significantly elevated cancer rates, and epidemiological data on human populations near plants shows a 2.5-fold cancer rate increase that persists after controlling for smoking and occupational exposures. (Correct answer)
Residents near industrial plants often have lower incomes and less access to healthcare.
Cancer has many known and suspected causes.

Correct answer: Animal studies exposing subjects to the chemical at these concentrations show significantly elevated cancer rates, and epidemiological data on human populations near plants shows a 2.5-fold cancer rate increase that persists after controlling for smoking and occupational exposures.

Convergent evidence from both animal studies (establishing mechanism) and human epidemiology (with confound control) provides multi-level support that strengthens the causal cancer risk claim.

Question 36: An airline that reduced the number of flights on a route to cut costs found that its revenue on that route actually increased. Which of the following most helps to explain this result?

Reducing flights created the impression of scarcity, attracting premium business travelers.
Air travel demand on the route was lower than the airline had anticipated.
Fewer flights meant higher load factors on remaining flights, and the higher average occupancy increased total revenue more than was lost from eliminated flights. (Correct answer)
The route became more competitive after the reduction, forcing the airline to lower prices.
The airline used the cost savings to invest in marketing.

Correct answer: Fewer flights meant higher load factors on remaining flights, and the higher average occupancy increased total revenue more than was lost from eliminated flights.

Higher load factors: fewer flights with fuller planes can generate more revenue than many half-empty flights if the demand is inelastic and passengers accommodate their schedules to the reduced frequency.

Question 37: Which of the following arguments most closely parallels the structure of: 'If a law is unjust, citizens are morally permitted to disobey it. This tax law is unjust. Therefore, citizens are morally permitted to disobey this tax law'?

If a contract is fraudulent, it is void. This contract is fraudulent. Therefore, this contract is void. (Correct answer)
If someone is guilty, they deserve punishment. The defendant deserves punishment. Therefore, the defendant is guilty.
Unjust laws should be repealed. Citizens can pressure legislators. Therefore, citizens should pressure legislators to repeal unjust laws.
If a policy is popular, it should be enacted. This policy is unpopular. Therefore, this policy should not be enacted.

Correct answer: If a contract is fraudulent, it is void. This contract is fraudulent. Therefore, this contract is void.

Both arguments apply a conditional rule (If P then Q) to a case where P is true, and validly conclude Q — option A mirrors this modus ponens structure precisely.

Question 38: Seven musicians—F, G, H, I, J, K, and L—perform one at a time in a recital. The following conditions apply: G performs sometime before J. H performs immediately before K. L performs sometime after I but before J. F performs first or last. Which of the following could be the order of performances, from first to last?

F, G, I, L, H, K, J (Correct answer)
I, H, K, L, G, J, F
F, H, K, G, I, L, J
G, I, L, H, K, J, F
G, F, I, L, H, K, J

Correct answer: F, G, I, L, H, K, J

Check F, G, I, L, H, K, J: F is first (satisfies F first or last). G(2) before J(7) ✓. H(5) immediately before K(6) ✓. I(3) before L(4) before J(7) ✓. All conditions satisfied.

Question 39: The jury found that while driving south on Maple Drive, the driver of the brown car ran a red light at the junction of First Street. Angie stated that she was traveling west on First Street in her blue Toyota. She further stated that a brown automobile struck her Toyota while she was driving through the intersection while the light was green and she was approaching Maple Drive. Angie's testimony was accepted by the jury, and they came to the conclusion that John, the owner of the brown automobile, was negligent in causing the incident. Was John careless based solely on these facts?

No, because no evidence shows that John was the driver of the brown car (Correct answer)
Yes, because John is the owner of the vehicle.
No, because Angie should not have driven through the intersection at that time.
Yes, because the driver of the brown car was negligent.

Correct answer: No, because no evidence shows that John was the driver of the brown car

The jury found that the *driver of the brown car* was negligent for running a red light. However, the conclusion drawn was that *John, the owner of the brown car*, was negligent. The provided facts only state that John *owns* the brown car; there is no evidence presented that explicitly identifies John as the *driver* of the brown car at the time of the accident. Without this crucial link, one cannot conclude that John was careless based *solely on these facts*, as ownership does not automatically equate to being the driver or being negligent.

Question 40: An author spends the first paragraph describing a scientific puzzle, the second presenting two competing hypotheses, and the final paragraph explaining why one hypothesis better fits the data. The primary purpose is to:

Argue that one hypothesis better explains the available evidence (Correct answer)
Describe experimental methods used by researchers
Summarize the history of a scientific field
Identify flaws in both competing hypotheses

Correct answer: Argue that one hypothesis better explains the available evidence

The structure—puzzle, competing explanations, evaluation—culminates in the author arguing that one hypothesis is superior, which is the primary purpose.

Question 41: The majority of the university's Spanish 101 students showed up to each class session during the previous semester. However, every pupil who obtained a grade of B minus or lower missed at least one class period. Which of the following claims regarding the university's Spanish 101 students from the previous semester may be correctly deduced from the facts above?

Most of the students received a grade higher than B minus.
At least some of the students who received a grade of A minus or higher attended every class session.
Most, if not all, of the students who missed at least one class session received a grade lower than B minus.
More than half of the students received a grade of B minus or higher (Correct answer)
At least one student who received a grade of B minus or higher missed one or more class sessions.

Correct answer: More than half of the students received a grade of B minus or higher

The facts state that 'Every pupil who obtained a grade of B minus or lower missed at least one class period.' This implies that any student who *attended every class session* must have received a grade *higher than B minus*. Since a 'majority' of students showed up to each class session (meaning they attended every class), it logically follows that a majority of students received a grade higher than B minus. If a majority received a grade higher than B minus, then it is certainly true that more than half received a grade of B minus or higher.

Question 42: Passage: Prior to the Supreme Court's decision in Erie Railroad Co. v. Tompkins (1938), federal courts hearing diversity jurisdiction cases applied a federal common law to substantive issues, under the authority of Swift v. Tyson (1842). Erie overruled Swift, holding that federal courts must apply state substantive law in diversity cases. The Court's reasoning included concern that the Swift doctrine had created forum shopping—plaintiffs choosing federal over state courts to gain favorable legal treatment—and had produced inequitable results where similarly situated parties received different outcomes based solely on which court they appeared before. Erie did not disturb the application of federal procedural rules, as codified in the Federal Rules of Civil Procedure. The Erie doctrine therefore requires courts to distinguish between substantive rules (governed by state law) and procedural rules (governed by federal law), a distinction that has proven difficult to draw and has generated significant subsequent litigation. According to the passage, the primary concern that led to the Erie decision was:

The need to establish a uniform federal common law.
The Supreme Court's concern that state courts lacked jurisdiction over diversity cases.
The excessive cost of litigation in federal courts compared to state courts.
Forum shopping and unequal treatment of similarly situated parties under the Swift doctrine. (Correct answer)
The failure of the Federal Rules of Civil Procedure to address substantive law questions.

Correct answer: Forum shopping and unequal treatment of similarly situated parties under the Swift doctrine.

The passage states the Erie Court was concerned that Swift 'had created forum shopping' and 'had produced inequitable results where similarly situated parties received different outcomes based solely on which court they appeared before.'

Question 43: Passage: The doctrine of promissory estoppel developed in common law as an equitable remedy to prevent unjust enrichment in cases where a party made a clear and definite promise that the promisee reasonably relied upon to their detriment, even absent formal consideration. The Restatement (Second) of Contracts codified this doctrine, requiring: (1) a promise that the promisor should reasonably expect to induce action or forbearance; (2) that did in fact induce such action or forbearance; and (3) that injustice can be avoided only by enforcement of the promise. Courts have applied promissory estoppel with varying degrees of liberality. Some jurisdictions require a high threshold of detrimental reliance, demanding that the promisee's reliance be objectively reasonable and the detriment substantial. Others have broadened the doctrine to encompass situations where the reliance is relatively minor if the promise was sufficiently clear. According to the passage, promissory estoppel developed primarily to address:

Cases where both parties failed to perform their contractual obligations.
Situations of unjust enrichment resulting from reliance on promises made without formal consideration. (Correct answer)
Statutory gaps in contract law left by the Uniform Commercial Code.
Disputes between commercial entities over lost profits.
Cases where written contracts were improperly drafted.

Correct answer: Situations of unjust enrichment resulting from reliance on promises made without formal consideration.

The passage explicitly states promissory estoppel developed 'to prevent unjust enrichment in cases where a party made a clear and definite promise that the promisee reasonably relied upon to their detriment, even absent formal consideration.'

Question 44: Passage (continued from above): According to the passage, after Erie, federal courts in diversity cases must:

Apply state law to both substantive and procedural questions.
Apply federal law to all questions, both substantive and procedural.
Apply state law to substantive questions but federal procedural rules. (Correct answer)
Allow parties to choose between state and federal law for each issue in the case.
Apply federal common law to substantive questions and state rules to procedural questions.

Correct answer: Apply state law to substantive questions but federal procedural rules.

The passage states 'federal courts must apply state substantive law in diversity cases' while Erie 'did not disturb the application of federal procedural rules,' establishing the substance/procedure split.

Question 45: Passage (continued from above): According to the passage, the Kepler Space Telescope detected exoplanets by:

Measuring the radio emissions from distant planetary systems.
Directly imaging planets using advanced optical technology.
Detecting the decrease in starlight when a planet passes in front of its star. (Correct answer)
Measuring gravitational effects of planets on their host stars.
Analyzing the spectral signatures of planetary atmospheres.

Correct answer: Detecting the decrease in starlight when a planet passes in front of its star.

The passage states Kepler detected exoplanets 'by detecting the tiny dips in starlight caused when a planet transits its host star'—the transit photometry method.

Question 46: Passage A argues that strict liability tort law protects consumers effectively. Passage B argues strict liability creates excessive costs for manufacturers. These passages are best characterized as:

One summarizing the other's argument
Offering competing policy assessments of the same legal doctrine (Correct answer)
Addressing different branches of tort law without overlap
Presenting complementary views on separate legal topics

Correct answer: Offering competing policy assessments of the same legal doctrine

Both passages evaluate strict liability tort law but reach opposing conclusions about its overall desirability, making them competing policy assessments.

Question 47: An LSAT passage about the Frye standard and the Daubert standard for expert scientific testimony states that Frye requires evidence to be 'generally accepted' in the relevant scientific community. Which of the following is a recognized criticism of the Frye standard compared to Daubert?

Frye requires courts to conduct their own independent scientific research before ruling on admissibility
Frye may exclude novel but well-validated scientific methods that have not yet achieved widespread acceptance (Correct answer)
Frye allows testimony from witnesses who are not members of the relevant professional community
Frye gives judges too much discretion to evaluate the reliability of scientific methodology

Correct answer: Frye may exclude novel but well-validated scientific methods that have not yet achieved widespread acceptance

The classic Frye criticism is that the general-acceptance requirement can exclude cutting-edge, rigorously validated science that has simply not yet gained mainstream adoption.

Question 48: Passage: The Fourth Amendment to the United States Constitution protects against unreasonable searches and seizures and generally requires law enforcement to obtain a warrant before conducting a search. However, courts have recognized numerous exceptions to the warrant requirement. The 'exigent circumstances' exception permits warrantless entry when officers reasonably believe immediate action is necessary to prevent physical harm, the destruction of evidence, or the escape of a suspect. The 'plain view' doctrine allows officers who are lawfully present in a location to seize evidence that is clearly visible without obtaining a warrant. The 'search incident to lawful arrest' exception permits officers to search the immediate area around an arrested person to prevent weapons retrieval or evidence destruction. Critics argue that these exceptions have eroded Fourth Amendment protections to the point where the warrant requirement is the exception rather than the rule. The primary purpose of the passage is to:

Describe the warrant requirement and several recognized exceptions to it. (Correct answer)
Provide a comprehensive list of all exceptions to the warrant requirement.
Compare American search and seizure law to international standards.
Argue that Fourth Amendment protections should be strengthened.
Explain why courts have rejected the Fourth Amendment in recent decades.

Correct answer: Describe the warrant requirement and several recognized exceptions to it.

The passage describes the warrant requirement and three specific exceptions, ending with critics' views. Its purpose is descriptive/explanatory rather than argumentative.

Question 49: A baker is cooking three pizzas, each with two toppings, one at a time. Anchovies, bacon, mushrooms, peppers, sausage, and tomatoes are among the six toppings accessible to the baker. There can be no more than one topping on a pizza. The following rules must be followed while pairing toppings: Peppers and anchovies are incompatible. On the same pizza, mushrooms and tomatoes must be present. If the first pizza has mushrooms, the second pizza must have sausage. Peppers must be added to a pizza after the sausage has been added. Which of the following is a possible pizza and toppings ordering scenario?

Sausage and bacon; mushrooms and tomatoes; anchovies and peppers
Mushrooms and tomatoes; sausage and peppers; bacon and anchovies
Sausage and tomatoes; peppers and anchovies; mushrooms and bacon
Sausage and anchovies; mushrooms and tomatoes; peppers and bacon (Correct answer)
Peppers and bacon; mushrooms and tomatoes; anchovies and sausage

Correct answer: Sausage and anchovies; mushrooms and tomatoes; peppers and bacon

Explanation: lf peppers must be on a pizza made after the sausage pizza, then peppers can never be on the first pizza or the same pizza as sausage. We can also easily eliminate any option in which tomatoes and mushrooms are not paired. Remember, sausage is only required to be on the second pizza if mushrooms are on the first.

Question 50: The Bee-Moth (Tinea mellonella), one of several honeybee adversaries, is by far the most feared in regions with hot summers. In this nation, its ravages have been so pervasive and deadly that millions have given up raising bees out of desperation, and in areas that used to produce copious amounts of the purest honey, beekeeping has progressively diminished into a very minor activity. Countless devices have been created to protect the bees from this vile enemy, but it still makes devasting inroads almost unchecked, mocking all the so-called "moth-proof" hives and converting many of the clever devices created to trap or exclude them into actual aids and comforts in its nefarious designs. If I couldn't demonstrate to the apiarist how he may safely resist the pestilential assaults of this, his most obstinate foe, I would have little faith in my ability to turn beekeeping in our nation back into a sure and lucrative endeavor. After years of meticulously observing its behaviors, I can finally present a management strategy based on the unique design of my hives that will allow the diligent beekeeper to defend his colonies against the monster. Just like weeds take control of rich soil, the bee-moth infests our apiaries. I'll briefly describe the moth's behavior before going into detail about the methods I use to avoid it. At the end of the seventeenth century, Swammerdam gave a very accurate description of this insect, then known as the "bee-wolf," and provided good drawings of it in all its stages, from worm to perfect moth, along with the peculiar webs or galleries that it creates and from which some entomologists gave it the name Tinea galleria or "gallery moth" However, he was unable to distinguish between the male and female, which he mistakenly believed to be two distinct species of wax-moth due to their extreme differences in size and appearance. It appears to have been a significant annoyance in his day, and even Virgil mentions the "dirum tineae genus," the terrifying moth's progeny, or the worm. This destroyer often appears around the beehives around April or May, depending on how warm the weather is or how far into the season it is. It seldom takes to the air before midnight and is obviously mostly nocturnal in its habits (unless disturbed from its hiding location around the hive). However, on dark, overcast days, I have observed it flying far before sundown, and if many of these days pass in a row, the female may be seen attempting to enter the hives as she is under extreme pressure to deposit her eggs. The female is much bigger than the male, and "her color is deeper and more inclining to a darkish gray, with small spots or blackish streaks on the interior edge of her upper wings." The male's color tends more toward a light gray; they may easily be confused for different species of moths. Surprisingly nimble on land and in the air, these insects. In contrast, a bee's movements are extremely sluggish. The moths will be seen flying or running around the hives, looking for an opportunity to enter, while the bees that have to guard the entrances against their intrusion will be seen acting as vigilant sentinels, performing continuous rounds near this important post, extending their antenna to the maximum, and moving them to the right and left. The poor moth that gets in their way will suffer!"It is interesting to see how cunningly the moth knows how to profit, to the detriment of the bees, who need a lot of light to see objects, and the precautions taken by the latter in recognizing and driving out such a dangerous enemy," explains Huber. Which of the following statements about bees is supported by the passage?

They are poor at caring for their young.
They are lithe.
They do not keep their hives in good condition.
They allow the bee-moth to enter their nests.
They will guard the entrance to their hives. (Correct answer)

Correct answer: They will guard the entrance to their hives.

The third paragraph, which states that "the bees that have to guard the entrances against their intrusion, will be seen acting as vigilant sentinels, performing continual rounds near this important post, extending their antenna to the utmost, and moving them to the right and left alternately. Woe to the unfortunate moth that comes within their reach!", supports this response.

Question 51: A city built a new highway bypass to reduce traffic congestion in its downtown core. Within three years, downtown congestion was worse than before the bypass was built. Which of the following most helps explain this paradox?

Construction of the bypass temporarily blocked downtown roads, creating habits of alternative routing that persisted after construction ended.
The highway bypass induced new traffic demand: easier regional access attracted new businesses and residents, generating more vehicle trips than the bypass removed. (Correct answer)
The bypass was built through residential neighborhoods, generating protest traffic from affected residents.
The bypass tolls were set too high, causing drivers to avoid it and continue using downtown streets.

Correct answer: The highway bypass induced new traffic demand: easier regional access attracted new businesses and residents, generating more vehicle trips than the bypass removed.

Induced demand means that new road capacity lowers the effective cost of driving, attracting new trips that fill and exceed the capacity added, a well-documented transportation paradox.

Question 52: A manager argues that open-plan offices increase productivity because employees can communicate more easily with each other. Which of the following most weakens this argument?

Studies show that noise and interruptions in open offices reduce individuals' ability to focus on complex tasks. (Correct answer)
The company recently hired 20 new employees who need workspace.
Some employees prefer working from home.
Open-plan offices are less expensive to build than offices with private rooms.
Communication technology allows employees to collaborate without being in the same room.

Correct answer: Studies show that noise and interruptions in open offices reduce individuals' ability to focus on complex tasks.

If noise and interruptions reduce focus on complex tasks, the communication benefits of open plans may be outweighed by decreased individual productivity, undermining the overall productivity claim.

Question 53: Seven athletes are divided into two relay teams—Red and Blue—each with 3 members, with one athlete as the coach's assistant not on either team. A and B cannot be on the same team. C must be on the Red team. D is the coach's assistant. E and F must be on the same team. G must be on the Blue team. Which of the following is an acceptable assignment?

Red: C, E, F; Blue: A, B, G
Red: A, C, G; Blue: B, E, F
Red: C, E, G; Blue: A, B, F
Red: A, C, E; Blue: B, F, G (Correct answer)
Red: B, C, F; Blue: A, E, G

Correct answer: Red: A, C, E; Blue: B, F, G

Check A: Red: A,C,E; Blue: B,F,G. A and B on different teams ✓. C on Red ✓. D is coach's assistant (not on either team) ✓. E and F on same team? E is on Red, F is on Blue—different teams ✗. Invalid.

Question 54: A tech executive argues that social media increases political polarization because users are exposed primarily to content that confirms their existing views. Which of the following most weakens this argument?

Social media companies have tried to reduce the spread of misinformation.
Research shows that political polarization has been rising since decades before social media existed. (Correct answer)
Younger generations use social media more than older generations.
Many users follow accounts with opposing political viewpoints.
Social media platforms use algorithmic feeds that prioritize engagement.

Correct answer: Research shows that political polarization has been rising since decades before social media existed.

If polarization was already increasing before social media existed, social media may not be the cause—correlation does not establish causation, especially when the trend predates the proposed cause.

Question 55: A psychologist argues that therapy is effective for treating depression because patients who complete therapy courses report lower depression symptoms than before treatment. Which of the following most weakens this argument?

Depression often resolves naturally over time, so patients might have improved without any treatment. (Correct answer)
Some patients drop out of therapy before completing their course.
Several types of therapy, including CBT and DBT, are used for depression.
The psychologist measured symptoms using a standardized scale.
Therapy is often combined with medication.

Correct answer: Depression often resolves naturally over time, so patients might have improved without any treatment.

Natural remission means improvement could occur regardless of treatment, making it impossible to attribute recovery to therapy without a proper control group.

Question 56: In a selection game, which deduction technique is most efficient when two items are linked by an 'if and only if' (biconditional) rule?

Use the contrapositive of only the forward direction
Treat the biconditional as two separate one-way conditionals (Correct answer)
Ignore one direction of the biconditional
Assume both items are always selected

Correct answer: Treat the biconditional as two separate one-way conditionals

A biconditional (A↔B) means A→B AND B→A; treating it as two conditionals captures all inferences.

Question 57: A science passage describes the development of mRNA vaccine technology, noting that it had been researched for decades before COVID-19 created conditions for rapid deployment. This historical context most likely serves to:

Demonstrate that private investment, not government funding, drove vaccine research
Show that mRNA technology should have been deployed in earlier pandemics
Counter the perception that mRNA vaccines were developed recklessly quickly by showing the underlying science was mature (Correct answer)
Argue that vaccine development was unnecessarily delayed by regulatory red tape

Correct answer: Counter the perception that mRNA vaccines were developed recklessly quickly by showing the underlying science was mature

Providing the decades-long research history addresses the concern that speed of development reflected inadequate safety testing.

Question 58: A historian argues that Nation X's economic growth in the 1990s was caused by free trade policies adopted in 1991, since growth accelerated immediately afterward. Which most weakens this argument?

Nation X also discovered large oil reserves in 1991, which could independently explain the growth. (Correct answer)
Free trade is generally endorsed by economists.
Nation X's inflation rate declined in 1993.
Neighboring countries also adopted free trade in the 1990s.

Correct answer: Nation X also discovered large oil reserves in 1991, which could independently explain the growth.

An alternative cause—the oil discovery—emerging at the same time undermines the conclusion that free trade policies caused the growth.

Question 59: A manager assigns 5 tasks—P, Q, R, S, T—to 3 employees—X, Y, Z. Each task goes to exactly one employee. Employee X gets at least 2 tasks. Q and R must go to the same employee. T must go to employee Y. S cannot go to the same employee as T. If P goes to employee X, which of the following is a complete and accurate assignment?

X: P, Q, S; Y: T; Z: R
X: P, S; Y: T, Q; Z: R
X: P, Q; Y: T, R; Z: S
X: P, R; Y: T, Q; Z: S
X: P, Q, R; Y: T; Z: S (Correct answer)

Correct answer: X: P, Q, R; Y: T; Z: S

Check X: P,Q,R; Y: T; Z: S. P→X ✓. Q and R same employee (both X) ✓. T→Y ✓. S not same as T (S on Z, T on Y) ✓. X has 3 tasks (≥2) ✓. Valid assignment.

Question 60: A conservation organization that successfully lobbied to protect additional forest land found that deforestation rates in surrounding unprotected areas increased after the protections were established. Which of the following most helps to explain this paradox?

The forest industry shifted its operations to unprotected areas once protected areas became legally inaccessible, concentrating deforestation pressure rather than reducing it. (Correct answer)
Unprotected forest owners preemptively deforested their land before regulations could extend to them.
Conservation organizations tend to focus on aesthetically valuable areas rather than ecologically important ones.
Protected areas require active management that draws conservation resources away from unprotected areas.
The new protections generated media attention that highlighted the forest as an economic resource.

Correct answer: The forest industry shifted its operations to unprotected areas once protected areas became legally inaccessible, concentrating deforestation pressure rather than reducing it.

Leakage effect: protecting forest in one area displaced logging pressure to adjacent unprotected areas rather than reducing total logging activity, concentrating and potentially increasing deforestation where protections don't apply.

Question 61: Five toddlers attend Big Bean Playroom: Amara, Bea, Calix, Danny, and Evia. Five trains, each of a different color, are lined up. Blue, Green, Orange, Red, and Yellow are the colors from left to right. Each child has their own train to play with. Calix despises the colors orange and yellow. Evia and his older brother Danny are separated by only one train. Amanda is seated between two little guys. Danny immediately snatches the blue train and refuses to share it. Amara might be playing with which train?

The yellow train.
The red train
The blue train.
The orange train. (Correct answer)

Correct answer: The orange train.

Explanation The correct answer The orange train

Question 62: Passage (continued from above): The passage indicates that Donoghue v. Stevenson (1932) was significant because it:

Extended the duty of care to manufacturers regarding ultimate consumers. (Correct answer)
Established the four-element framework for negligence claims.
Limited duty of care to contractual relationships.
First applied negligence principles to cases involving physical injury.
Created the reasonable person standard in tort law.

Correct answer: Extended the duty of care to manufacturers regarding ultimate consumers.

The passage states Donoghue v. Stevenson 'established that manufacturers owe a duty to the ultimate consumers of their products,' marking its significance.

Question 63: A climate scientist argues that ocean acidification caused by CO2 absorption is harming coral reef ecosystems. Which of the following most strengthens this argument?

Coral reefs support approximately 25% of marine biodiversity.
Oceans absorb approximately 30% of human-produced CO2 emissions.
Ocean temperatures have been rising alongside acidification.
Some coral species appear more resilient to acidification than others.
Controlled aquarium experiments exposing coral to seawater with elevated CO2 concentrations show measurably reduced calcification rates and skeletal weakening at concentrations already observed in some ocean regions. (Correct answer)

Correct answer: Controlled aquarium experiments exposing coral to seawater with elevated CO2 concentrations show measurably reduced calcification rates and skeletal weakening at concentrations already observed in some ocean regions.

Controlled experiments demonstrating the specific biological mechanism at CO2 concentrations already present in some ocean regions provides strong causal evidence linking acidification to coral harm.

Question 64: 1Every schoolboy is familiar with the broad strokes of Macaulay's life and work, to use one of his own favorite adages. We have recited the Lays, presumably read some of the History, and perhaps even heard of his eloquent and unrestrained criticism of writers whose works offended him. Even if his assertions weren't always correct, we know that his recall was incredible. The biographers go on to say that no one could be more uncomplicated or more dedicated to his own family; his nephews and nieces were unaware of his greatness and considered him to be their favorite "Uncle Tom." Of course, criticism is far from unanimity. 'Macaulay, the great prophet of Whiggery which never had or will have a prophet, vehemently judged that a man who could pass over from the celestial Whigs to the infernal Tories must be a traitor false as Judas, an apostate black,' observed Mr. Augustine Birrell wryly. James Thomson epitomized his political bias in a biting sentence: "Macaulay, historiographer in chief to the Whig Always a youngster at heart and utterly unconcerned with his appearance, Macaulay had such incredible success in every field that envy may be to blame for the majority of personal criticism that isn't motivated by obvious rivals. Those who referred to him as a bore were probably being overly sensitive about their own incapacity to counter ideas or viewpoints that they yearned to oppose. When the magnificent piece on the translation of a recently discovered Milton dissertation on Christian Doctrine appeared in the Edinburgh (1825) and unleashed a new force in English prose, he was a student at Lincoln's Inn. Even though Macaulay admitted it was "overloaded with garish and ungraceful argument," it cemented his literary reputation and shaped a significant portion of his career. He gained control over the 21Edinburgh, perhaps slightly altering its overall tone, and started to identify with its reputation. Christopher North claims that "the son of a Saint," who appears to be some sort of reviewer, is "insidious as the serpent, but fangless as the glow worm." The Tory press, of course, was outraged at the champion critic of their favorite prodigies. Choose the introductory phrase that is most likely to result in agreement from both passage authors.

Locating recorded historical data of astronomical changes as far back as the days of the glacial epoch may produce further climate facts affected by astrological movements of our solar system.
The ambiguity of climate changes infer that a cause and effect study of the earths' atmosphere from the sun to below Earths surface may not bring clarity due to the eccentricity of earth's orbit. (Correct answer)
Geologists are responsible for researching climate changes on Earth and not from the angle of the earth to sun energy scenario.
Volcanic dust and eruptions are not as peculiar to geologist as the localization of Ice glaziers and their changes.

Correct answer: The ambiguity of climate changes infer that a cause and effect study of the earths' atmosphere from the sun to below Earths surface may not bring clarity due to the eccentricity of earth's orbit.

Through making assertions and citing evidence relating to the climate impacts, such as the cause and effect of astronomical causes to our geological climate and passage B's intention to understand the geological changes from the earth's surface and below, both authors identified with the effects of climate change and crisis. Additional response options are either inaccurate claims not contained in either passage or do not connect to the core issue focus of the two passages, which is climate impacts.

Question 65: Political Analyst: 'Councilman Thompson's proposal to fund a new public park is fiscally irresponsible. We cannot trust his judgment on public spending, as it was recently revealed that he has significant personal credit card debt and recently declared bankruptcy. Therefore, the city council should reject his proposal.' The analyst's argument is most vulnerable to criticism on which one of the following grounds?

It does not consider the potential benefits that a new public park could bring to the city.
It assumes that personal financial management skills are relevant to managing public funds.
It fails to provide any evidence that the park proposal itself is fiscally irresponsible.
It attacks the councilman's personal financial situation instead of the merits of his proposal. (Correct answer)

Correct answer: It attacks the councilman's personal financial situation instead of the merits of his proposal.

The argument commits an ad hominem fallacy. Instead of analyzing the details, costs, and benefits of the park proposal, the analyst attacks Councilman Thompson's personal character and financial history. The merits of an argument or proposal are independent of the character of the person presenting it. The argument shifts focus from the proposal to the person, which is a logical flaw.

Question 66: A committee of 3 is selected from 7 candidates: A, B, C, D, E, F, G. B and D cannot both be selected. If A is selected, C must also be selected. E cannot be selected with F. Which of the following could be a complete and accurate committee?

A, C, D
D, E, G
B, C, F
A, B, E
A, C, F (Correct answer)

Correct answer: A, C, F

Check A, C, F: A is selected and C is selected ✓ (A→C). B and D: neither is selected ✓. E and F: E not selected ✓. Valid committee.

Question 67: A Florida-based company called Sunrise Travel sells cruises and other types of holiday packages. It has 500 employees. Except for the President and other executives chosen by the Board of Directors, all employees of Sunrise Travel are deemed to be at-will workers, according to the company's articles of incorporation. Sunrise Travel's president is Mr. Santos. All at-will employees of Sunrise Travel are subject to the policies in the employee handbook, which was published by the company's human resources division. Would it be accurate for a paralegal to get to the conclusion that Mr. Santos is exempt from the policies in the employee handbook?

No, because being an officer of Sunrise Travel does not preclude application of the handbook. (Correct answer)
Yes, because Mr. Hernandez is not considered an at-will employee of Sunrise Travel.
No, because the handbook was not approved by the Board of Directors.
Yes, because the President is not considered an at-will employee of Sunrise Travel.

Correct answer: No, because being an officer of Sunrise Travel does not preclude application of the handbook.

The company's articles of incorporation explicitly state that the President and other executives are *not* considered at-will employees. The employee handbook, however, states that 'All at-will employees of Sunrise Travel are subject to the policies in the employee handbook.' Since Mr. Santos is the President and therefore not an at-will employee, his status does not automatically exempt him from *all* policies within the handbook. The handbook might contain general policies applicable to all employees, or specific policies for officers, even if the 'at-will' specific provisions do not apply to him. Thus, concluding he is entirely exempt based solely on his non-at-will status is not necessarily accurate.

Question 68: On the LSAT, when a question asks 'The argument depends on which assumption?' it is asking for a:

Causal assumption
Sufficient assumption
Necessary assumption (Correct answer)
Conditional assumption

Correct answer: Necessary assumption

The word 'depends on' signals a necessary assumption—something the argument cannot do without.

Question 69: Five presentations—W, X, Y, Z, V—are scheduled for consecutive time slots. Y is in slot 3. X is after W. V is immediately after Z. If W is in slot 1 and the Z-V block is in slots 4 and 5, which is the complete and accurate schedule?

W, Z, Y, V, X
W, V, Y, Z, X
W, Y, X, Z, V
X, W, Y, Z, V
W, X, Y, Z, V (Correct answer)

Correct answer: W, X, Y, Z, V

W=1, Y=3, Z=4, V=5 (Z-V block in 4-5). X must come after W(1) and fill the remaining slot 2. Order: W, X, Y, Z, V.

Question 70: Political Analyst: A candidate who does not win the support of young voters will not be elected president. Since candidate Miller has focused her campaign on issues that are of primary concern to young voters, she is likely to be elected president.

No other candidate has focused on issues of primary concern to young voters.
Candidate Miller will win the support of young voters.
Focusing a campaign on issues of primary concern to young voters is sufficient to win their support. (Correct answer)
Issues of primary concern to young voters are the most important issues in the presidential election.

Correct answer: Focusing a campaign on issues of primary concern to young voters is sufficient to win their support.

This is a sufficient assumption question. The argument's structure is: Premise 1: Not winning young voters -> Not elected. Premise 2: Miller focused on young voters' issues. Conclusion: Miller will be elected. There's a leap from 'focusing on their issues' to 'winning their support' and another from there to being 'elected'. The correct answer must bridge this gap completely. Answer A, if assumed true, connects the premise (focusing on issues) to the necessary condition for winning (winning their support), making the argument logically valid. Specifically, it guarantees Miller wins the support of young voters, which allows the conclusion to be drawn.

Question 71: A public health official argues that mandatory vaccination programs reduce disease outbreaks because high vaccination rates create herd immunity. Which of the following most weakens this argument?

Mandatory programs may face legal challenges.
Some vaccines require booster shots to maintain effectiveness.
Vaccine hesitancy has increased in recent years.
Some people cannot be vaccinated for medical reasons.
The diseases targeted by the program have low transmission rates, meaning herd immunity thresholds may never be breached anyway. (Correct answer)

Correct answer: The diseases targeted by the program have low transmission rates, meaning herd immunity thresholds may never be breached anyway.

If the diseases have low transmission rates and outbreaks are unlikely regardless of vaccination policy, the mandatory program may not be necessary to prevent outbreaks, weakening the causal claim.

Question 72: Which of the following arguments most closely parallels this reasoning: 'Since all published research requires peer review, and this manuscript has not been peer reviewed, it should not be cited as established science'?

Since all licensed drivers must pass a test, and this person passed a test, they must be a licensed driver.
Since all science requires evidence, and this claim lacks evidence, scientists should ignore it.
Since some peer-reviewed articles contain errors, peer review is not a guarantee of accuracy.
Since all legitimate currencies are government-issued, and this token is not government-issued, it is not legitimate currency. (Correct answer)

Correct answer: Since all legitimate currencies are government-issued, and this token is not government-issued, it is not legitimate currency.

The original argument has the form: All X require Y; this lacks Y; therefore it is not X — option B mirrors this structure exactly with currencies and government issuance.

Question 73: Senator: My opponent argues we should raise the minimum wage, but he has accepted donations from labor unions. His argument should therefore be dismissed. What flaw is present?

Ad hominem — attacking the source rather than the argument (Correct answer)
False dichotomy — presenting only two options
Appeal to authority — citing an unqualified expert
Straw man — misrepresenting the opponent's position

Correct answer: Ad hominem — attacking the source rather than the argument

The senator attacks the opponent's funding source rather than addressing the actual merits of the minimum wage argument.

Question 74: An environmental group argues that offshore wind farms harm marine ecosystems because whale strandings increased in areas near wind farm construction sites. Which most weakens this argument?

Wind farm construction generates significant noise below the water surface.
Whales are protected under international maritime law.
Wind farms require extensive underwater infrastructure.
Ship traffic near whale habitats also increased significantly during the same construction period, and ship collisions are a known cause of whale strandings. (Correct answer)

Correct answer: Ship traffic near whale habitats also increased significantly during the same construction period, and ship collisions are a known cause of whale strandings.

Increased ship traffic is an alternative explanation for the strandings that coincides with but is independent of wind farm construction.

Question 75: A country's government raised the minimum wage, intending to help low-income workers. Economic data showed that average household income among the lowest-earning quintile fell in the following year. Which of the following most helps explain this paradox?

The minimum wage increase was too small to make a meaningful difference in workers' purchasing power.
Low-income workers spent their higher wages on taxable goods, increasing their tax burden.
Higher wages attracted more workers into the labor market, increasing competition for low-wage jobs.
Some employers responded by reducing employee hours or cutting positions, leaving total income for some workers lower despite the higher hourly rate. (Correct answer)

Correct answer: Some employers responded by reducing employee hours or cutting positions, leaving total income for some workers lower despite the higher hourly rate.

If employers reduce hours or eliminate positions in response to higher mandated wages, some workers' total annual earnings decline even as the per-hour rate rises.

Question 76: Passage (continued from above): According to the passage, why do pharmaceutical companies currently have reduced incentives to develop new antibiotics?

International regulations restrict the profitability of antibiotic sales.
New antibiotics face regulatory barriers that delay market approval.
Antibiotic research requires more advanced technology than companies possess.
Antibiotics are used briefly and may quickly become ineffective, making them less profitable than chronic disease treatments. (Correct answer)
Consumer demand for new antibiotics is insufficient to justify research investment.

Correct answer: Antibiotics are used briefly and may quickly become ineffective, making them less profitable than chronic disease treatments.

The passage states 'these drugs are used briefly and may quickly lose effectiveness—making them less profitable than treatments for chronic conditions.'
