Consider the following premises. For all x_9, if x_9 were an electrician, then x_9 is an artist. For all x_9, if x_9 were poor, then x_9 is an artist. For all x_9, x_9 is rich or x_9 is a poet. For all x_9, x_9 is not a poet or x_9 is an electrician. For all x_9, x_9 is not rich or x_9 is poor. Can we infer the following from them? There is at least one y for which y is an artist.
 From the fact that for all x_9, x_9 is rich or x_9 is a poet, and that for all x_9, x_9 is not rich or x_9 is poor we can infer that for all x_9, x_9 is a poet or x_9 is poor. From the fact that for all x_9, x_9 is a poet or x_9 is poor, and that for all x_9, x_9 is not a poet or x_9 is an electrician we can infer that for all x_9, x_9 is poor or x_9 is an electrician. From the fact that for all x_9, if x_9 were poor, then x_9 is an artist, that for all x_9, if x_9 were an electrician, then x_9 is an artist, and that for all x_9, x_9 is poor or x_9 is an electrician we can infer that for all x_9, x_9 is an artist. From the fact that for all x_9, x_9 is an artist we can infer that Mary is an artist. Finally, from the fact that Mary is an artist we can infer that there is at least one y for which y is an artist. Therefore, the answer is yes.
