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: U(z) -> P_1(z). forall z: U(z) or ~P_1(z). forall z: T(z) -> U(z).
forall z: T(z) -> P_1(z) can be inferred via the universal transitivity rule. forall z: P_1(z) -> U(z) can be inferred via the universal rewriting rule.
