LSAT Ultimate 3 â Questions and Answers
Question 1: A principle question on the LSAT asks you to apply a general rule to a specific case. Which answer choice correctly applies the principle 'An action is permissible only if it benefits the actor without harming others' to a scenario?
- A driver speeds to reach the hospital faster, even though it endangers pedestriansâpermissible because it benefits the driver
- A student copies a friend's homework, saving time without anyone noticingâpermissible because no one is harmed
- A baker gives leftover bread to the homeless, benefiting others at cost to herselfâpermissible because it helps others
- A manager takes credit for an employee's idea, gaining a promotion while the employee loses recognitionânot permissible because it harms another (Correct answer)
Correct answer: A manager takes credit for an employee's idea, gaining a promotion while the employee loses recognitionânot permissible because it harms another
The manager's action harms another (the employee loses recognition), so it violates the principle that actions must not harm others.
Question 2: In a sequencing game, seven candidatesâA, B, C, D, E, F, Gâare interviewed one at a time. B is interviewed before D. E is interviewed immediately after C. A is last. Which of the following must be true?
- C is interviewed before B
- G is interviewed before F
- E is not interviewed sixth (Correct answer)
- D is not interviewed first
Correct answer: E is not interviewed sixth
Since A is last (7th) and E immediately follows C, E cannot be 6th (which would require C to be 6th and A also to be 7th but E takes 7th)âwait, E cannot be 7th since A is 7th, so E is at most 6th, but if E is 6th then C is 5th, which is possible; however, E cannot be 7th, making answer C correct because E must be in positions 2â6 with C one before E, and A occupying 7th forces E to be at most 6th.
Question 3: Which of the following represents a valid 'Modus Tollens' argument form?
- If P then Q; P is true; therefore Q is true
- If P then Q; Q is false; therefore P is false (Correct answer)
- If P then Q; P is false; therefore Q is false
- If P then Q; Q is true; therefore P is true
Correct answer: If P then Q; Q is false; therefore P is false
Modus Tollens: If P â Q, and Q is false (not-Q), then P must be false (not-P)âdenying the consequent to deny the antecedent.
Question 4: An LSAT stimulus contains an 'appeal to authority' flaw. Which answer choice best describes this flaw?
- The argument concludes that because something has always been done a certain way, it must be correct
- The argument uses the opinion of an expert in an unrelated field to support its conclusion (Correct answer)
- The argument attacks the character of an opponent rather than addressing their reasoning
- The argument assumes that because two events occurred together, one caused the other
Correct answer: The argument uses the opinion of an expert in an unrelated field to support its conclusion
An appeal to authority is flawed when the cited authority lacks relevant expertise in the specific domain being argued.
Question 5: Which LSAT Reading Comprehension question type asks you to identify information that the passage does NOT provide support for?
- Main Point
- Inference (must be true) (Correct answer)
- Author's Attitude
- Cannot Be Determined from the Passage
Correct answer: Inference (must be true)
Inference questions asking what 'must be true' sometimes have a variant asking what CANNOT be true or is NOT supported, testing your ability to stay within what the passage actually states.
Question 6: In a grouping game, four projectsâW, X, Y, Zâare assigned to teams Red and Blue, with at least one project per team. W and Z cannot be on the same team. X must be on the Red team. Which of the following could be a complete and accurate assignment?
- Red: W, X, Y; Blue: Z (Correct answer)
- Red: X, Z; Blue: W, Y
- Red: X; Blue: W, Y, Z
- Red: W, X, Z; Blue: Y
Correct answer: Red: W, X, Y; Blue: Z
Red: W, X, Y and Blue: Z satisfies all conditionsâX is on Red, W and Z are on different teams, and each team has at least one project.
Question 7: A 'weaken' question asks you to undermine an argument's conclusion. The most effective weakener does which of the following?
- Provides an alternative explanation that makes the conclusion unnecessary (Correct answer)
- Directly contradicts a stated premise in the stimulus
- Introduces a new topic unrelated to the argument's scope
- Confirms that the conclusion is possible but not certain
Correct answer: Provides an alternative explanation that makes the conclusion unnecessary
The most effective weakener provides an alternative explanation that accounts for the evidence without requiring the stated conclusion.
