Consider the following premises. For all y, if y were an office clerk, then y is reading a book. For all y, if y reads a book, then y is an office clerk. Jennifer is not an office clerk. Can we infer the following from them? Jennifer is reading a book.
 From the fact that for all y, if y reads a book, then y is an office clerk, and that for all y, if y were an office clerk, then y is reading a book we can infer that for all y, y will read a book if and only if y is an office clerk. From the fact that for all y, y will read a book if and only if y is an office clerk we can infer that for all y, if y reads a book, then y is an office clerk. From the fact that for all y, if y reads a book, then y is an office clerk we can infer that if Jennifer reads a book, then Jennifer is an office clerk. Finally, from the fact that if Jennifer reads a book, then Jennifer is an office clerk, and that Jennifer is not an office clerk we can infer that Jennifer is not reading a book, which contradicts that Jennifer is reading a book. Therefore, the answer is no.
