Consider the following premises. For all x_15, x_15 is a nurse or x_15 is a sailor. For all x_15, x_15 will drive a car or x_15 is not a sailor. For all x_15, if x_15 were a nurse, then x_15 is driving a car. For all x_15, x_15 will not read a book. There is at least one x_15 for which x_15 will read a book or x_15 is a server. Can we infer the following from them? There is at least one x_15 for which x_15 will drive a car and x_15 is a server.
 From the fact that for all x_15, x_15 will drive a car or x_15 is not a sailor we can infer that for all x_15, if x_15 were a sailor, then x_15 is driving a car. From the fact that there is at least one x_15 for which x_15 will read a book or x_15 is a server, and that for all x_15, x_15 will not read a book we can infer that there is at least one x_15 for which x_15 is a server. From the fact that for all x_15, if x_15 were a nurse, then x_15 is driving a car, that for all x_15, if x_15 were a sailor, then x_15 is driving a car, and that for all x_15, x_15 is a nurse or x_15 is a sailor we can infer that for all x_15, x_15 will drive a car. Finally, from the fact that for all x_15, x_15 will drive a car, and that there is at least one x_15 for which x_15 is a server we can infer that there is at least one x_15 for which x_15 will drive a car and x_15 is a server. Therefore, the answer is yes.
