Consider the following premises. For all x_5, x_5 will climb a mountain or x_5 is poor. There is at least one x_5 for which x_5 will not climb a mountain. For all x_5, x_5 is a soldier. Can we infer the following from them? There is at least one x_5 for which x_5 is poor and x_5 is a soldier.
 From the fact that for all x_5, x_5 will climb a mountain or x_5 is poor, and that there is at least one x_5 for which x_5 will not climb a mountain we can infer that there is at least one x_5 for which x_5 is poor. Finally, from the fact that there is at least one x_5 for which x_5 is poor, and that for all x_5, x_5 is a soldier we can infer that there is at least one x_5 for which x_5 is poor and x_5 is a soldier. Therefore, the answer is yes.
