Consider the following premises. For all x_13, if x_13 were poor, then x_13 is a poet. William is a lawyer or Robert is not poor. For all x_13, if x_13 were a poet, then x_13 is poor. Can we infer the following from them? The fact that Robert were a poet does not imply that William is a lawyer.
That contradicts the premises. Therefore the answer is no.
