Consider the following premises. For all z_3, z_3 will read a book. If Linda were a mechanic, then James is a nurse. For all z_3, if z_3 reads a book, then z_3 is a mechanic. Can we infer the following from them? James is not a nurse.
 From the fact that for all z_3, if z_3 reads a book, then z_3 is a mechanic, and that for all z_3, z_3 will read a book we can infer that for all z_3, z_3 is a mechanic. From the fact that for all z_3, z_3 is a mechanic we can infer that Linda is a mechanic. Finally, from the fact that if Linda were a mechanic, then James is a nurse, and that Linda is a mechanic we can infer that James is a nurse, which contradicts that James is not a nurse. Therefore, the answer is no.
