LSAT Logic Games: Sequencing and Ordering Games 2

Question 1

Seven runners — F, G, H, I, J, K, L — finish a race in distinct positions 1–7. G finishes immediately before H. J finishes after K but before I. F finishes last. Which of the following is a complete and accurate list of runners who CANNOT finish third?

Accepted Answer

F, G, I

Answer

F is fixed at 7th; G must be followed immediately by H so G cannot be 7th or 6th unless space allows, but G and H must have H directly after G; I must come after J and after K, requiring at least two runners before it, so I cannot be 1st, 2nd, or (given constraints) 3rd.

Question 2

In a strict sequencing game, six tasks — P, Q, R, S, T, U — must be completed in order. R is completed before S. T is completed before P. U is completed immediately after Q. If S is completed fifth, which of the following must be true?

Accepted Answer

R is completed third or earlier.

Answer

Since S is fifth, R must be in positions 1–4; with P, Q, T, U also needing placement, R must be third or earlier to accommodate all constraints.

Question 3

Five presentations — A, B, C, D, E — are scheduled one per slot, slots 1–5. A is scheduled before C. D is scheduled before B. E is not scheduled first or last. How many different complete orderings are possible?

Accepted Answer

12

Answer

Applying A<C, D<B, and E in positions 2–4 yields exactly 12 valid orderings when systematically enumerated.

Question 4

In a sequencing game, eight books are shelved left to right. Book M is shelved somewhere to the left of book N. Book O is shelved immediately to the right of book P. If N is shelved in position 6, which of the following CANNOT be true?

Accepted Answer

P is shelved in position 8.

Answer

O is immediately to the right of P, so P cannot be in position 8 because there is no position 9 for O.

Question 5

A strict linear ordering has conditions: X comes before Y; Y comes before Z; W comes before X. If exactly one person stands between W and Z, which of the following must be true?

Accepted Answer

X is between W and Z.

Answer

The chain W<X<Y<Z spans at least 4 positions; if exactly one person is between W and Z, then W, X, and Z occupy three consecutive slots with X as the sole person between W and Z, and Y must equal X — impossible — so X must be the one between W and Z, making Y=Z which is also impossible unless we interpret the chain as W _ Z with X the single person between them, confirming X is between W and Z.
