Consider the following premises. For all x_3, if x_3 were a poet, then x_3 is a janitor. There is at least one x_3 for which if x_3 were bored, then x_3 is a poet. For all x_3, if x_3 were a janitor, then x_3 is bored. Can we infer the following from them? For all x_3, the fact that x_3 were a poet does not imply that x_3 is bored.
That contradicts the premises. Therefore the answer is no.
