What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y: ~W_2(y). forall y: T_4(y) <-> U_4(y). forall y: W_2(y) <-> T_4(y). U_4(b_4) <-> p.
U_4(b_4) -> p. p -> U_4(b_4). forall y: T_4(y) -> U_4(y). forall y: W_2(y) -> T_4(y). forall y: U_4(y) -> T_4(y). forall y: T_4(y) -> W_2(y). forall y: ~T_4(y).
