Consider the following premises. For all x_5, x_5 will drive a car or x_5 is a soldier. For all x_5, if x_5 listens to a song, then x_5 is a musician. For all x_5, if x_5 were a soldier, then x_5 is listening to a song. For all x_5, if x_5 drives a car, then x_5 is a musician. For all x_5, x_5 is an astronaut. Can we infer the following from them? For all x_5, x_5 is a musician and x_5 is an astronaut.
 From the fact that for all x_5, if x_5 were a soldier, then x_5 is listening to a song, and that for all x_5, if x_5 listens to a song, then x_5 is a musician we can infer that for all x_5, if x_5 were a soldier, then x_5 is a musician. From the fact that for all x_5, if x_5 drives a car, then x_5 is a musician, that for all x_5, if x_5 were a soldier, then x_5 is a musician, and that for all x_5, x_5 will drive a car or x_5 is a soldier we can infer that for all x_5, x_5 is a musician. Finally, from the fact that for all x_5, x_5 is a musician, and that for all x_5, x_5 is an astronaut we can infer that for all x_5, x_5 is a musician and x_5 is an astronaut. Therefore, the answer is yes.
