Consider the following premises. There is at least one x_8 for which if x_8 were a soldier, then x_8 is curious. For all x_8, if x_8 were curious, then x_8 is climbing a mountain. For all x_8, if x_8 climbs a mountain, then x_8 is a soldier. For all x_8, x_8 is a soldier. Can we infer the following from them? There is at least one x_8 for which x_8 is curious.
 From the fact that for all x_8, if x_8 were curious, then x_8 is climbing a mountain, and that for all x_8, if x_8 climbs a mountain, then x_8 is a soldier we can infer that for all x_8, if x_8 were curious, then x_8 is a soldier. From the fact that for all x_8, if x_8 were curious, then x_8 is a soldier, and that there is at least one x_8 for which if x_8 were a soldier, then x_8 is curious we can infer that there is at least one x_8 for which x_8 is curious if and only if x_8 is a soldier. From the fact that there is at least one x_8 for which x_8 is curious if and only if x_8 is a soldier we can infer that there is at least one x_8 for which if x_8 were a soldier, then x_8 is curious. Finally, from the fact that there is at least one x_8 for which if x_8 were a soldier, then x_8 is curious, and that for all x_8, x_8 is a soldier we can infer that there is at least one x_8 for which x_8 is curious. Therefore, the answer is yes.
