#9 - Local, Must Be True

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=3673)

The correct answer choice is (E)

This question introduces a number of local conditions, so it is best to take them one step at a time:

If G is shown exactly three times, it must be the last film shown on Friday and Saturday in
compliance with the second and the third rules. G must also be shown on Thursday, before H,
because H must be shown last on Thursday according to the first rule:

We are also asked to show H twice. H is already being shown on Thursday (first rule), but it
cannot be shown on Saturday with G (third rule). Therefore, H must be shown on Friday:

Finally, we need to show L exactly once. G and L cannot both be shown on Friday (second rule),
and so L must be shown on either Thursday or Saturday. The film showings on each day are now
completely defined:

With these two solutions in place, the correct answer to this Must Be True question can easily be
prephrased: both solutions show that H and G are the only two films shown on Friday, which
immediately validates answer choice (E).

Answer choice (A) is not necessarily true, because it is possible that only two films are shown on
Thursday.

Answer choice (B) is not necessarily true, because only one film can be shown on Saturday.

Answer choice (C) is not necessarily true, because L need not be shown on Thursday.

Answer choice (D) is not necessarily true, because L could also be shown on Saturday.

Answer choice (E) is the correct answer choice, as explained above.
