What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_9: Q_3(x_9) -> T(x_9). forall x_9: W(x_9) or Q(x_9). forall x_9: ~W(x_9) or S_2(x_9). forall x_9: Q(x_9) -> Q_3(x_9). forall x_9: S_2(x_9) <-> T(x_9).
forall x_9: Q(x_9) -> T(x_9). forall x_9: Q(x_9) or S_2(x_9). forall x_9: S_2(x_9) -> T(x_9). forall x_9: T(x_9) -> S_2(x_9).
