Consider the following premises. For all x_11, if x_11 climbs a mountain, then x_11 is a nurse. There is at least one x_11 for which if x_11 were a bartender, then x_11 is sleeping. For all x_11, x_11 will climb a mountain or x_11 is not sad. For all x_11, if x_11 sleeps, then x_11 is sad. Can we infer the following from them? If we can, name the inference rule being used: For all x_11, the fact that x_11 were a bartender does not imply that x_11 is a nurse.
That contradicts the premises. Therefore the answer is no.
