What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y_4: W(y_4) or T_4(y_4). forall y_4: T(y_4) -> U(y_4). forall x_18: P_18(x_18). forall y_4: T_4(y_4) -> T(y_4). forall y_4: W(y_4) -> T(y_4).
forall y_4: T_4(y_4) -> U(y_4). forall y_4: W(y_4) -> U(y_4). forall y_4: T(y_4).
