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: Q_2(z) -> S(z). forall z: T_2(z) -> Q_2(z). forall z: S(z) -> R_3(z).
forall z: Q_2(z) -> R_3(z) can be inferred via the universal transitivity rule. forall z: T_2(z) -> S(z) can be inferred via the universal transitivity rule.
