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 z_4: Q(z_4) -> P(z_4). forall z_4: Q(z_4) or ~S(z_4). forall z_4: P(z_4) -> S(z_4).
forall z_4: Q(z_4) -> S(z_4) can be inferred via the universal transitivity rule. forall z_4: S(z_4) -> Q(z_4) can be inferred via the universal rewriting rule.
