#18 - Local, Must Be True

[Dave Killoran]

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?f=307&t=9348)

The correct answer choice is (D)

If G is inspected on Monday morning and Z is inspected on Wednesday morning, then from the fourth rule L must be inspected on Tuesday morning:

From the third rule, S cannot be inspected on Monday afternoon, and so S must be inspected on Tuesday afternoon or Wednesday afternoon:

Accordingly, answer choice (D) is correct.



Overall, this is a very tough game, and most students felt it was the most difficult game on this exam.

Can you please post an explanation for Q18?

Hi NR2020,

This Local, Must Be True question asks you to put G on Monday morning, and Z on Wednesday morning. With those two variables in place, the fourth rule, Z(morning) L(morning), forces you to put L in the morning. The only remaining morning space is Tuesday morning, so put L there. With G on Monday morning, that means (from the third rule) that S cannot be on Monday afternoon. That means that S must be on Tuesday afternoon or Wednesday afternoon. Since those are the only two possible placements for S, that means answer choice D, "Lido is inspected before Seville is inspected." must be true, and is the correct answer. A diagram of the Local setup to the question is posted below.
