Q10

by ManhattanPrepLSAT1 Mon Oct 07, 2013 2:19 pm

10. (D)
Question Type: Conditional

This question gives us multiple pieces of extra, conditional ("If") information that will apply to this question only: L is shown three times, H twice, and G once. Given these conditions, we’re looking for a complete and accurate list of the films that could be the first film shown on Thursday.
Again, we want to start by using the additional information to create an inference chain.
First, if L is shown three times, then L must be shown on Thursday. We already know that H must be shown on Thursday as well, and that nothing can follow H on Thursday (H must be last). So, L must be shown before H on Thursday. Thus, H CANNOT be shown first on Thursday. We can eliminate any answer that includes H. Eliminate (A), (C), and (E).
We’re down to (B) and (D). Both contain L, so we know that L can indeed be shown first on Thursday. The real question is whether G can be shown first. Let’s try it:

Why wasn't another scenario of the diagram written as:
Thurs: L, H, Frid: H,L, Sat: L, G.

IF the diagram was written this way, then B would be correct too.

You're correct in thinking that you wrote AN ADDITIONAL scenario that shows that L could be first on Thursday.

However, that doesn't make (B) correct.

G can also be first on Thursday.
Since G and L can each be first on Thursday,
then a complete list of the films that could be the first film would be
G and L.

(B) would be wrong because it's incomplete. It leaves off the possibility that G could also be the first film on Thurs.

Hope this helps.
