Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=8560)
The correct answer choice is (B)
This question is a direct test of your Not Laws. Since L cannot be at 1 PM (first rule), whereas Z must be at 1 PM (main inference, as explained above), L and Z cannot be given at the same time.
Answer choice (A): This answer choice is incorrect, because L and Y can both be at 2 PM. For instance:
Answer choice (B): This is the correct answer choice. Note that if you did not make this inference ahead of time, this question would require you to “plug-and-chug,” i.e. try out every pair of variables—each at both 1 PM and 2 PM—in order to identify the pair that cannot be at either time slot. This would be an inordinate amount of work, which merely serves to emphasize the importance of investing more time and energy at the initial setup of the game.
Answer choice (C): This answer choice is incorrect, because M and X can both be at 2 PM. For instance:
Answer choice (D): This answer choice is incorrect, because X and Y can both be at 2 PM. For instance:
Answer choice (E): This answer choice is incorrect, because Y and Z can both be at 1 PM. For instance:
