The correct answer choice is (A)
This is probably the most difficult question in this game, because an efficient approach is not immediately apparent. When your main setup does not contain the information to answer a Global Cannot Be True question immediately, your first step should be to examine prior work.
In question #14, our local diagram shows that M and R could both be located in aisle 2 without violating any of the rules. This eliminates answer choice (B). For the remaining four answer choices, consider the variables listed and their effect on the setup:
Answer choice (A): This is the correct answer choice. If H and M are the only variables in aisle 2, this would force S to be in aisle 3, which is impossible thanks to the third rule of the game. Therefore, H and M cannot be the sections located in aisle 2.
Answer choice (C): This answer choice seems unlikely to be correct. From question #14, we know that M and R can both be located in aisle 2 without violating any of the rules. The same is also true for M and S. Although S and R are not functionally identical, they function similarly in this context: Answer choice (D): This answer choice is also unlikely to be correct. We already know that H and S can form a block in aisle 2, and there is no reason why this block cannot be joined by M: Answer choice (E): M, R, and S could all be located in aisle 2, as shown in the setup below, making answer choice (E) also incorrect:
