What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y_4: T_1(y_4) -> W_1(y_4). forall y_4: T_1(y_4). forall y_4: U_2(y_4).
forall y_4: W_1(y_4). forall y_4: T_1(y_4) and U_2(y_4). forall y_4: U_2(y_4) and T_1(y_4).
