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_1: ~S_1(z_1). forall z_1: S_1(z_1) or ~Q_3(z_1). exists z_1: S_1(z_1) -> Q_3(z_1).
forall z_1: Q_3(z_1) -> S_1(z_1) can be inferred via the universal rewriting rule.
