Consider the following premises. For all x_5, if x_5 were an electrician, then x_5 is a doctor. For all x_5, if x_5 drives a car, then x_5 is a writer. For all x_5, if x_5 were a doctor, then x_5 is reading a book. For all x_5, x_5 is an electrician or x_5 will drive a car. For all x_5, if x_5 were a writer, then x_5 is reading a book. Can we infer the following from them? There is at least one x_5 for which x_5 will not read a book.
 From the fact that for all x_5, if x_5 drives a car, then x_5 is a writer, and that for all x_5, if x_5 were a writer, then x_5 is reading a book we can infer that for all x_5, if x_5 drives a car, then x_5 is reading a book. From the fact that for all x_5, if x_5 were an electrician, then x_5 is a doctor, and that for all x_5, if x_5 were a doctor, then x_5 is reading a book we can infer that for all x_5, if x_5 were an electrician, then x_5 is reading a book. Finally, from the fact that for all x_5, if x_5 were an electrician, then x_5 is reading a book, that for all x_5, if x_5 drives a car, then x_5 is reading a book, and that for all x_5, x_5 is an electrician or x_5 will drive a car we can infer that for all x_5, x_5 will read a book, which contradicts that There is at least one x_5 for which x_5 will not read a book. Therefore, the answer is no.
