Consider the following premises. For all y, y is poor or y is not rich. For all y, y is rich and y will make tea. Can we infer the following from them? For all y, y is poor.

From the fact that for all y, y is rich and y will make tea we can infer that for all y, y is rich. Finally, from the fact that for all y, if y were rich, then y is poor, and that for all y, y is rich we can infer that for all y, y is poor. Therefore, the answer is yes.
