Consider the following premises. For all x_7, if x_7 were a nurse, then x_7 is a poet. There is at least one x_7 for which if x_7 takes a plane, then x_7 is a nurse. For all x_7, x_7 will take a plane or x_7 is not a lawyer. Can we infer the following from them? If we can, name the inference rule being used: For all x_7, the fact that x_7 were a lawyer does not imply that x_7 is a poet.
That contradicts the premises. Therefore the answer is no.
