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_3: ~P(z_3). forall z_3: S(z_3) or ~P(z_3). forall z_3: S(z_3) -> P(z_3).
forall z_3: ~S(z_3) can be inferred via the universal modus tollens rule. forall z_3: P(z_3) -> S(z_3) can be inferred via the universal rewriting rule.
