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.
