Consider the following premises. If Elisabeth were a poet, then Richard is climbing a mountain. If Susan were a janitor, then Elisabeth is a poet. For all x_14, x_14 is a cashier if and only if x_14 will climb a mountain. Can we infer the following from them? The fact that Susan were a janitor does not imply that Richard is a cashier.
That contradicts the premises. Therefore the answer is no.
