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: forall y: P_2(y) -> S_3(y). forall y: P_2(y) and W(y).
forall y: P_2(y) can be inferred via the universal simplification rule. forall y: W(y) can be inferred via the universal simplification rule.
