What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall z: P_1(z) <-> T_2(z). forall z: T_2(z) <-> R_3(z). forall z: ~P_1(z).
forall z: P_1(z) -> T_2(z). forall z: T_2(z) -> R_3(z). forall z: T_2(z) -> P_1(z). forall z: R_3(z) -> T_2(z). forall z: ~T_2(z).
