Consider the following premises. There is at least one x_5 for which if x_5 reads a book, then x_5 is not a soldier. For all x_5, x_5 is a soldier. For all x_5, x_5 will drink water. Can we infer the following from them? There is at least one x_5 for which x_5 will not read a book.
 From the fact that for all x_5, x_5 is a soldier, and that for all x_5, x_5 will drink water we can infer that for all x_5, x_5 is a soldier and x_5 will drink water. From the fact that for all x_5, x_5 is a soldier and x_5 will drink water we can infer that for all x_5, x_5 is a soldier. Finally, from the fact that there is at least one x_5 for which if x_5 reads a book, then x_5 is not a soldier, and that for all x_5, x_5 is a soldier we can infer that there is at least one x_5 for which x_5 will not read a book. Therefore, the answer is yes.
