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: T_2(z) -> P(z). forall z: P(z) -> U_3(z). forall z: U_3(z) -> T_2(z). forall z: T_2(z) or ~U_3(z).
forall z: T_2(z) -> U_3(z) can be inferred via the universal transitivity rule. forall z: P(z) -> T_2(z) can be inferred via the universal transitivity rule. forall z: U_3(z) -> P(z) can be inferred via the universal transitivity rule. forall z: U_3(z) -> T_2(z) can be inferred via the universal rewriting rule.
