Q8

[Emily Madan]

8. The correct answer is (C).

As a conditional question, we should start by seeing what inferences can be made based on the new condition. Jackson going on Wednesday means there is one remaining spot on Monday and two on Tuesday. Because H can’t go on Monday, he has to go to Tuesday. F and G are split up between the one spot on Monday on the other on Tuesday. With that knowledge, we can evaluate what must be true. Remember that most of these answers will likely be possible, but we can eliminate anything that is not certain. Possible is still wrong.

(A) Could be true, but Monday could be either F or G. This answer choice is not a must be true. Eliminate it.

(B) Eliminate this for the exact same reason we eliminated (A)

(C) We know this must be true. Either F or G but not both and no one else is on Monday. This is the correct answer.

At this point, we know the answer, so we should pick (C) and move on. However, let’s review the last two choices for thoroughness.

(D) This must be false because we only have one person on Monday

(E) This answer choice is possible, but F could easily be paired with H as well. This is not a must be true.
