What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_9: P_9(x_9) or Q_4(x_9). forall x_9: W_3(x_9) -> P_9(x_9). exists x_9: T_2(x_9) -> ~W_3(x_9). forall x_9: Q_4(x_9) -> W_3(x_9). forall x_9: P_9(x_9) -> W_3(x_9).
forall x_9: Q_4(x_9) -> P_9(x_9). forall x_9: W_3(x_9). forall x_9: W_3(x_9) <-> P_9(x_9). forall x_9: P_9(x_9) <-> W_3(x_9).
