Consider the following premises. For all x_3, x_3 is a poet and x_3 will listen to a song. For all x_3, x_3 will drink water. Can we infer the following from them? If we can, name the inference rule being used: For all x_3, x_3 will drink water and x_3 is a poet.
 From the fact that for all x_3, x_3 is a poet and x_3 will listen to a song we can infer that for all x_3, x_3 is a poet via universal simplification. Finally, from the fact that for all x_3, x_3 will drink water, and that for all x_3, x_3 is a poet we can infer that for all x_3, x_3 will drink water and x_3 is a poet via universal conjunction. Therefore, the answer is yes.
