What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: For all y, y will make tea or y will not climb a mountain. For all y, y will not make tea. For all y, if y makes tea, then y is climbing a mountain.
For all y, if y climbs a mountain, then y is making tea can be inferred via the universal rewriting rule.
