Consider the following premises. For all x_14, x_14 is poor if and only if x_14 will climb a mountain. For all x_14, x_14 will make tea if and only if x_14 will play tennis. There is at least one x_14 for which x_14 is not poor. For all x_14, x_14 will climb a mountain if and only if x_14 will play tennis. Can we infer the following from them? For all x_14, x_14 will make tea.
 From the fact that for all x_14, x_14 is poor if and only if x_14 will climb a mountain, and that there is at least one x_14 for which x_14 is not poor we can infer that there is at least one x_14 for which x_14 will not climb a mountain. From the fact that for all x_14, x_14 will climb a mountain if and only if x_14 will play tennis, and that there is at least one x_14 for which x_14 will not climb a mountain we can infer that there is at least one x_14 for which x_14 will not play tennis. Finally, from the fact that for all x_14, x_14 will make tea if and only if x_14 will play tennis, and that there is at least one x_14 for which x_14 will not play tennis we can infer that there is at least one x_14 for which x_14 will not make tea, which contradicts that For all x_14, x_14 will make tea. Therefore, the answer is no.
