Hi kmlane!

If U is mentioned in chapter 3, that means that X must be in chapter 2 or 4. I would start by trying out both options. Once X is placed, we have to think about where that T __ __ W block goes. If X is in chapter 2, then the only place left for T __ __ W is 4/7. If X is in chapter 4, then the only place left for T __ __ W is in 2/5. But this would put X next to W, which cannot happen. Therefore, we know that only the option with X in chapter 2 works. At that point, we still have S, Z, and R to place and we only have chapters 1, 5, and 6 open. S and Z cannot be next to each other which means they cannot be in chapters 5 and 6. So one of them has to be in chapter 1. Thus, R will be in chapter 5 or 6 and whichever one of S and Z is not in chapter 1 will also be in either 5 or 6.

The local diagram would look something like this:

From the diagram, we can see that answer choices (A), (C), (D), and (E) cannot happen. Answer choice (B) is the only one that could be true (R could be 5 or 6) and, thus, it is correct.

Hope this helps!
