What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_3: P_2(x_3) <-> W_4(x_3). forall x_3: Q_4(x_3) -> P_2(x_3). forall x_3: ~W_4(x_3). forall x_3: W_4(x_3) -> P_2(x_3).
forall x_3: P_2(x_3) -> W_4(x_3). forall x_3: W_4(x_3) -> P_2(x_3). forall x_3: ~P_2(x_3).
