What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one x_10 for which if x_10 climbs a mountain, then x_10 is a bartender. For all x_10, if x_10 were a bartender, then x_10 is climbing a mountain. For all x_10, if x_10 works, then x_10 is a bartender. For all x_10, x_10 will not climb a mountain.
For all x_10, x_10 is not a bartender. For all x_10, if x_10 works, then x_10 is climbing a mountain. There is at least one x_10 for which x_10 will climb a mountain if and only if x_10 is a bartender. There is at least one x_10 for which x_10 is a bartender if and only if x_10 will climb a mountain.
