Consider the following premises. For all x_1, if x_1 were curious, then x_1 is climbing a mountain. For all x_1, x_1 is a bartender. There is at least one x_1 for which if x_1 were a bartender, then x_1 is curious. Can we infer the following from them? There is at least one x_1 for which x_1 will climb a mountain.
 From the fact that there is at least one x_1 for which if x_1 were a bartender, then x_1 is curious, and that for all x_1, if x_1 were curious, then x_1 is climbing a mountain we can infer that there is at least one x_1 for which if x_1 were a bartender, then x_1 is climbing a mountain. Finally, from the fact that there is at least one x_1 for which if x_1 were a bartender, then x_1 is climbing a mountain, and that for all x_1, x_1 is a bartender we can infer that there is at least one x_1 for which x_1 will climb a mountain. Therefore, the answer is yes.
