Consider the following premises. For all x_5, x_5 will make tea. For all x_5, if x_5 were a sailor, then x_5 is an astronaut. For all x_5, if x_5 makes tea, then x_5 is a sailor. For all x_5, if x_5 were an astronaut, then x_5 is a poet. Can we infer the following from them? For all x_5, x_5 is a poet.
 From the fact that for all x_5, if x_5 makes tea, then x_5 is a sailor, and that for all x_5, if x_5 were a sailor, then x_5 is an astronaut we can infer that for all x_5, if x_5 makes tea, then x_5 is an astronaut. From the fact that for all x_5, if x_5 makes tea, then x_5 is an astronaut, and that for all x_5, x_5 will make tea we can infer that for all x_5, x_5 is an astronaut. Finally, from the fact that for all x_5, if x_5 were an astronaut, then x_5 is a poet, and that for all x_5, x_5 is an astronaut we can infer that for all x_5, x_5 is a poet. Therefore, the answer is yes.
