Consider the following premises. For all y, y will read a book or y will drive a car. There is at least one y for which if y works, then y is reading a book. For all y, if y reads a book, then y is working. For all y, y will not work. Can we infer the following from them? For all y, y will not drive a car.
 From the fact that there is at least one y for which if y works, then y is reading a book, and that for all y, if y reads a book, then y is working we can infer that there is at least one y for which y will work if and only if y will read a book. From the fact that there is at least one y for which y will work if and only if y will read a book, and that for all y, y will not work we can infer that there is at least one y for which y will not read a book. Finally, from the fact that for all y, y will read a book or y will drive a car, and that there is at least one y for which y will not read a book we can infer that there is at least one y for which y will drive a car, which contradicts that For all y, y will not drive a car. Therefore, the answer is no.
