Consider the following premises. For all x_6, if x_6 were a soldier, then x_6 is fast. For all x_6, if x_6 were fast, then x_6 is curious. There is at least one x_6 for which if x_6 were an astronaut, then x_6 is a soldier. For all x_6, if x_6 were rich, then x_6 is an astronaut. Can we infer the following from them? There is at least one x_6 for which if x_6 were rich, then x_6 is curious.
 From the fact that for all x_6, if x_6 were a soldier, then x_6 is fast, and that for all x_6, if x_6 were fast, then x_6 is curious we can infer that for all x_6, if x_6 were a soldier, then x_6 is curious. From the fact that for all x_6, if x_6 were rich, then x_6 is an astronaut, and that there is at least one x_6 for which if x_6 were an astronaut, then x_6 is a soldier we can infer that there is at least one x_6 for which if x_6 were rich, then x_6 is a soldier. Finally, from the fact that there is at least one x_6 for which if x_6 were rich, then x_6 is a soldier, and that for all x_6, if x_6 were a soldier, then x_6 is curious we can infer that there is at least one x_6 for which if x_6 were rich, then x_6 is curious. Therefore, the answer is yes.
