LSAT Logic Games: Sequencing and Ordering Games 4 — Questions and Answers
Question 1: In a sequencing game, the phrase 'at least two positions before' means:
- The first variable's position number is at least 2 less than the second's. (Correct answer)
- The two variables are exactly 2 positions apart.
- The first variable immediately precedes the second.
- There is at most one variable between them.
Correct answer: The first variable's position number is at least 2 less than the second's.
If X is at least two positions before Y, then Y's position − X's position ≥ 2, meaning at least one other slot separates them.
Question 2: A game places five runners in finishing positions 1–5. Clues: H finishes before J; J finishes before K; L finishes before H. Which of the following is a complete list of runners that COULD finish first?
- L only (Correct answer)
- L or H
- H or J
- L, H, or J
Correct answer: L only
The chain L<H<J<K means L must come before H, H before J, and J before K; only L has no one required before it, so only L can finish first.
Question 3: In a sequencing game, you are told 'either P is before Q, or R is before S, but not both.' If R is before S, which of the following must be true?
- Q is before P. (Correct answer)
- P is before Q.
- P and Q are adjacent.
- R is immediately before S.
Correct answer: Q is before P.
Since the constraint is an exclusive or, if R is before S (second condition is true), then P before Q (first condition) must be false — meaning Q is before P.
Question 4: Six musicians perform in sequence. Violinist (V) performs sometime before Cellist (C). Guitarist (G) performs immediately after Drummer (D). Pianist (P) performs last. Flutist (F) performs first. If C performs third, which of the following could be the complete performance order?
- F, V, C, D, G, P (Correct answer)
- F, D, C, G, V, P
- F, D, G, C, V, P
- V, F, C, D, G, P
Correct answer: F, V, C, D, G, P
F first, V second, C third, D fourth, G fifth (G immediately after D), P last — all constraints satisfied.
Question 5: A sequencing game involves eight packages delivered in order. Package T is delivered exactly three positions after Package R. If R is delivered second, in what position is T delivered?
- 4th
- 5th (Correct answer)
- 6th
- 3rd
Correct answer: 5th
R in position 2, plus exactly 3 positions later, places T in position 2 + 3 = 5.
Question 6: In a linear ordering game, the clue 'X is not first and not last' combined with 'Y is last' means:
- X can be in any position except the first and the last occupied by Y. (Correct answer)
- X and Y must be adjacent.
- X is in the second-to-last position.
- X is always immediately before Y.
Correct answer: X can be in any position except the first and the last occupied by Y.
X is excluded from position 1 and from the last position (which is fixed as Y's), so X can occupy any middle position.
Question 7: In a complex sequencing game, the contrapositive of 'If A is third, then B is fifth' is:
- If B is not fifth, then A is not third. (Correct answer)
- If B is fifth, then A is third.
- If A is not third, then B is not fifth.
- If A is fifth, then B is third.
Correct answer: If B is not fifth, then A is not third.
The contrapositive of 'If P then Q' is 'If not Q then not P,' so the contrapositive is 'If B is not fifth, then A is not third.'
