Remember in the setup I said that only the Turner, the Vuillard, and the Whistler can go between the Renoir and the Morisot?
This restriction is rather central. In this question, the Turner is beside the Vuillard. That means that neither the Turner nor the Vuillard can go in between R_M. So only Whistler can.
Once you make a deduction like that, it usually answers the question. B is CORRECT. The Renoir must always come before the Whistler, because they go in this order: RWM
This may not be a satisfactory explanation for this question. That’s the trouble with questions like this. Either they take forever, and you solve them with brute force, or you solve them quickly.
I personally didn’t figure out the solution in advance. I make one scenario with the Turner next to the Vuillard. In the process of drawing, I noticed that the Renoir had to be before the Whistler, and at that point I realized there was no other way.
Making drawings is a revelation. You see things you could never possibly realize if you just try to think a question through. If I can teach you one thing, it’s this: practice drawing, rather than thinking.
I’ll repeat that, because it’s important. Instead of thinking: draw, and draw quickly. In the process of drawing, you will figure things out.
To draw well, and fast, you need to know the rules. There’s no substitute for this.

Mr. Blake,
Here is a little better explanation for Preptest 71 section II question 23:
The key is the fact that P&S are not required to be in any order at anytime and according to the rules for order; T will be hung closer to the door than W….these two rules allow the following painting order, PSVTRWM. Now if you read the question it says which pair of paintings in which the one mentioned first must be closer to the entrance than the one mentioned second. Thus, PS is not required to be in any order, thus you skip to V and it is fixed at 3 or 4 and is not a pair according to rule and then you have T and W and this pair fits the question and the rules and the order…The only pair that can be read according to rule.
