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