LSAT (Law School Admission Test)Analytical ReasoningEasy
A group of six friends—F, G, H, I, J, K—are planning a road trip. They must decide on the order in which they will drive, with each friend driving exactly once. The following conditions apply: * J must drive immediately before K. * F cannot drive first. * G must drive sometime after H. * I must drive third. Which of the following could be the order in which the friends drive?
- AH, G, I, F, J, K
- BH, F, I, J, K, G
- CG, H, I, J, K, F
- DF, H, I, J, K, G
Show answer & explanationAnswer & explanation
Correct answer: B. H, F, I, J, K, G
We need to find an order that satisfies all four given conditions. By systematically checking each option against the rules, we can identify the valid sequence.
Why the other options are wrong
- A. Violates the rule that J must drive immediately before K; F is between J and K.
- C. Violates the rule that F cannot drive first, and G is before H.
- D. Violates the rule that F cannot drive first.
Ordering Rules Application
Applying a set of sequential constraints to determine valid arrangements of elements.
- Each element appears exactly once.
- Rules dictate positions or relative order.
- Systematic checking of options is often effective.
