Consider the following premises. For all x_14, if x_14 makes tea, then x_14 is a poet. For all x_14, x_14 will make tea. There is at least one x_14 for which x_14 will make tea if and only if x_14 is a poet. For all x_14, if x_14 sleeps, then x_14 is a poet. Can we infer the following from them? There is at least one x_14 for which x_14 is a poet.
 From the fact that there is at least one x_14 for which x_14 will make tea if and only if x_14 is a poet we can infer that there is at least one x_14 for which if x_14 were a poet, then x_14 is making tea. From the fact that for all x_14, if x_14 makes tea, then x_14 is a poet, and that there is at least one x_14 for which if x_14 were a poet, then x_14 is making tea we can infer that there is at least one x_14 for which x_14 will make tea if and only if x_14 is a poet. From the fact that for all x_14, x_14 will make tea we can infer that for all x_14, x_14 will make tea or x_14 will sleep. From the fact that there is at least one x_14 for which x_14 will make tea if and only if x_14 is a poet we can infer that there is at least one x_14 for which if x_14 makes tea, then x_14 is a poet. Finally, from the fact that there is at least one x_14 for which if x_14 makes tea, then x_14 is a poet, that for all x_14, if x_14 sleeps, then x_14 is a poet, and that for all x_14, x_14 will make tea or x_14 will sleep we can infer that there is at least one x_14 for which x_14 is a poet. Therefore, the answer is yes.
