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, if x_8 drinks water, then x_8 is climbing a mountain. For all x_8, if x_8 goes running, then x_8 is drinking water. For all x_8, x_8 will climb a mountain if and only if x_8 is a carpenter. For all x_8, x_8 is not a carpenter.
For all x_8, if x_8 goes running, then x_8 is climbing a mountain. For all x_8, if x_8 climbs a mountain, then x_8 is a carpenter. For all x_8, if x_8 were a carpenter, then x_8 is climbing a mountain. For all x_8, x_8 will not climb a mountain.
