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:
