What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall z_4: W(z_4) <-> T_2(z_4). forall z_4: W(z_4) -> T_2(z_4). forall z_4: ~T_2(z_4).
forall z_4: ~W(z_4). forall z_4: W(z_4) -> T_2(z_4). forall z_4: T_2(z_4) -> W(z_4). forall z_4: ~W(z_4).
