I put together the setup with all of the inferences that you can make before you begin the questions. The color coded boxes refer to two places that must have the same character assigned.
There are two rows for Rosenberg and two rows for Juarez, keeping track of both the order of the books for each as well as what kind of book each is. Sometimes, even if we don't know which book goes where, we'll still know whether it's an advanced book or else and introductory book.
Hope this helps!
