What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_9: W(x_9) -> T(x_9). forall x_9: Q_5(x_9) -> T(x_9). forall x_9: W(x_9) and Q_9(x_9). forall x_9: S(x_9) -> ~T(x_9).
forall x_9: W(x_9). forall x_9: Q_9(x_9).
