LSAT Ultimate 2 — Questions and Answers
Question 1: In a logical reasoning question, which of the following most accurately describes the flaw of 'affirming the consequent'?
- Concluding that because P implies Q, and Q is true, P must be true (Correct answer)
- Concluding that because P implies Q, and P is false, Q must be false
- Concluding that because P implies Q, and Q is false, P must be false
- Concluding that because P and Q are both true, P must imply Q
Correct answer: Concluding that because P implies Q, and Q is true, P must be true
Affirming the consequent incorrectly assumes that if the conclusion of a conditional is true, the premise must also be true.
Question 2: An LSAT Reading Comprehension passage discusses two competing theories. Which question type most commonly follows such a dual-passage structure?
- Identify the main point of only one passage
- Compare the relationship between the two passages' arguments (Correct answer)
- Determine the author's tone in the second passage only
- Find a specific detail mentioned in one passage
Correct answer: Compare the relationship between the two passages' arguments
Comparative reading questions require you to analyze how the two passages relate—agree, disagree, or complement each other.
Question 3: In an analytical reasoning game, five books—F, G, H, J, K—are placed on shelves 1 through 5. G is on a higher shelf than F. H is on shelf 3. Which of the following CANNOT be true?
- F is on shelf 1 and G is on shelf 2
- F is on shelf 2 and G is on shelf 4
- F is on shelf 4 and G is on shelf 5
- G is on shelf 1 (Correct answer)
Correct answer: G is on shelf 1
G must be on a higher shelf than F, so G cannot be on shelf 1 because no shelf is lower than 1 for F to occupy.
Question 4: Which LSAT question stem signals a 'Strengthen' question?
- Which one of the following, if true, most seriously weakens the argument?
- Which one of the following, if true, most helps to justify the conclusion? (Correct answer)
- The argument is most vulnerable to criticism on the grounds that it fails to consider which one of the following?
- Which one of the following is an assumption on which the argument depends?
Correct answer: Which one of the following, if true, most helps to justify the conclusion?
'Most helps to justify the conclusion' is a classic strengthen question stem asking you to add support to the argument.
Question 5: A stimulus states: 'All competitive law schools require high LSAT scores. Riverside Law is not a competitive school.' What can properly be concluded?
- Riverside Law does not require high LSAT scores
- Riverside Law may or may not require high LSAT scores (Correct answer)
- Students with high LSAT scores will not attend Riverside Law
- Riverside Law accepts all applicants regardless of LSAT score
Correct answer: Riverside Law may or may not require high LSAT scores
The conditional only tells us what competitive schools require; it says nothing about what non-competitive schools require.
Question 6: On the LSAT, 'parallel reasoning' questions ask you to find an answer choice that:
- Uses the same topic as the stimulus argument
- Has the same logical structure and validity as the stimulus argument (Correct answer)
- Strengthens the conclusion of the stimulus argument
- Identifies the assumption in the stimulus argument
Correct answer: Has the same logical structure and validity as the stimulus argument
Parallel reasoning questions require matching the logical form—premises leading to a conclusion in the same way—not the subject matter.
Question 7: Which of the following best describes the LSAT's Analytical Reasoning section's primary cognitive skill test?
- Memorizing legal rules and applying them to fact patterns
- Deducing conclusions from sets of given conditions and constraints (Correct answer)
- Evaluating the credibility of witnesses in legal scenarios
- Interpreting statutory language and legislative intent
Correct answer: Deducing conclusions from sets of given conditions and constraints
Analytical Reasoning (Logic Games) tests the ability to understand rules and deduce what must, can, or cannot be true given those constraints.
