What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_7: W(x_7) and Q_7(x_7). forall x_7: S(x_7) <-> W(x_7).
forall x_7: W(x_7). forall x_7: Q_7(x_7). forall x_7: S(x_7) -> W(x_7). forall x_7: W(x_7) -> S(x_7).
