Consider the following premises. For all x_5, if x_5 drives a car, then x_5 is reading a book. For all x_5, x_5 will read a book if and only if x_5 is a soldier. There is at least one x_5 for which x_5 is a soldier. Can we infer the following from them? There is at least one x_5 for which x_5 will read a book.
 From the fact that there is at least one x_5 for which x_5 is a soldier we can infer that there is at least one x_5 for which x_5 is a soldier or x_5 will drive a car. From the fact that for all x_5, x_5 will read a book if and only if x_5 is a soldier we can infer that for all x_5, if x_5 were a soldier, then x_5 is reading a book. Finally, from the fact that for all x_5, if x_5 were a soldier, 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 there is at least one x_5 for which x_5 is a soldier or x_5 will drive a car we can infer that there is at least one x_5 for which x_5 will read a book. Therefore, the answer is yes.
