Consider the following premises. For all x_1, x_1 is not a server. There is at least one x_1 for which if x_1 reads a book, then x_1 is a janitor. For all x_1, if x_1 were a janitor, then x_1 is a server. Can we infer the following from them? For all x_1, x_1 will read a book.
 From the fact that for all x_1, if x_1 were a janitor, then x_1 is a server, and that for all x_1, x_1 is not a server we can infer that for all x_1, x_1 is not a janitor. Finally, from the fact that there is at least one x_1 for which if x_1 reads a book, then x_1 is a janitor, and that for all x_1, x_1 is not a janitor we can infer that there is at least one x_1 for which x_1 will not read a book, which contradicts that For all x_1, x_1 will read a book. Therefore, the answer is no.
