What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_8, x_8 is a janitor or x_8 will climb a mountain. For all x_8, if x_8 were a janitor, then x_8 is cooking. For all x_8, x_8 will cook if and only if x_8 will climb a mountain. There is at least one x_8 for which if x_8 were a police officer, then x_8 is not cooking.
For all x_8, if x_8 cooks, then x_8 is climbing a mountain. For all x_8, if x_8 climbs a mountain, then x_8 is cooking.
