Consider the following premises. For all x, x is a doctor or x will not read a book. For all x, x is not a doctor. Can we infer the following from them? For all x, x will not read a book.
 From the fact that for all x, x is a doctor or x will not read a book we can infer that for all x, if x reads a book, then x is a doctor. Finally, from the fact that for all x, if x reads a book, then x is a doctor, and that for all x, x is not a doctor we can infer that for all x, x will not read a book. Therefore, the answer is yes.
