Since this is a "could be true" question, all the incorrect answer choices CANNOT be true. Let's see why (B) cannot be true.

Let's first quickly review the setup for the game:

An art gallery is scheduling 5 consecutive exhibitions - J K L N O. During the opening reception, one of five musicians will perform - T V W Y Z. The game requires us to determine the order of the exhibitions and match musicians to the artists.

A: __ __ __ __ __
M: __ __ __ __ __

The following rules apply:

(1) J exhibit is earlier than K, and K is earlier than L.

This rule tells us we have the following chain: J - K - L.

(2) T performs earlier than V, who performs earlier than W.

This rule tells us we have the following musician chain - T - V- W.

(3) W does not perform in the 4th week.

A: __ __ __ __ __
~K ~L ~J ~J
~L ~K
M: __ __ __ __ __
~W ~W ~W ~T
~V ~T ~V

We can infer that W can only perform in weeks 3 or 5.

(4) Y does not perform at the N exhibition.
(5) Z performs at the O exhibition.

The question asks us if T performs at J exhibition and V performs at K exhibition which of the following could be true?

Since we have the following chains - J - K -L and T-V-W, and match T/J and K/V, we know that W must perform later at N exhibition since Z performs at O and Y cannot perform at N, so Y must perform at L.


Let's look at (B) and (E):

(B) N exhibition is in the 4th week.

If N exhibition is in the 4th week, then W must perform in the 4th week, which violates rule (3). Thus, we can conclude that it cannot be true.

(E) Z performs in the third week.

If Z performs in the third week, O exhibition must be third. J K L exhibitions could be 1,2, and 4 respectively, and N exhibition -fifth.

A: J K O L N
M: T V Z Y W

Since this scenario complies with all the rules, we can conclude that (E) could be true.

Let me know if this makes sense and if you have any further questions.

I realized I made a careless error buy assignment 2 artists and 2 musicians together when I diagrammed it the first time, causing the confusion. Makes senses now. Thank you
