Consider the following premises. There is at least one x_5 for which x_5 is a soldier. For all x_5, if x_5 were a soldier, then x_5 is reading a book. For all x_5, x_5 is a cashier. Can we infer the following from them? For all x_5, x_5 will not read a book.
 From the fact that for all x_5, if x_5 were a soldier, then x_5 is reading a book, and that there is at least one x_5 for which x_5 is a soldier we can infer that there is at least one x_5 for which x_5 will read a book. From the fact that there is at least one x_5 for which x_5 will read a book, and that for all x_5, x_5 is a cashier we can infer that there is at least one x_5 for which x_5 will read a book and x_5 is a cashier. Finally, from the fact that there is at least one x_5 for which x_5 will read a book and x_5 is a cashier we can infer that there is at least one x_5 for which x_5 will read a book, which contradicts that For all x_5, x_5 will not read a book. Therefore, the answer is no.
