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: T(z_1) or S(z_1). exists z_1: ~S(z_1) or Q(z_1). forall z_1: ~T(z_1) or R_4(z_1).
forall z_1: S(z_1) or R_4(z_1) can be inferred via the universal resolution rule.
