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) -> S_3(z_1). forall z_1: W_2(z_1) -> T_2(z_1). exists z_1: T_2(z_1) -> T(z_1). forall z_1: S_3(z_1) -> W(z_1).
forall z_1: T(z_1) -> W(z_1) can be inferred via the universal transitivity rule. exists z_1: T_2(z_1) -> S_3(z_1) can be inferred via the existential transitivity rule. exists z_1: W_2(z_1) -> T(z_1) can be inferred via the existential transitivity rule.
