What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x: S(x) -> Q(x). exists x: T_3(x) -> W(x). forall x: Q(x) -> T_3(x). forall x: W(x) -> S(x).
forall x: S(x) -> T_3(x). forall x: W(x) -> Q(x). exists x: T_3(x) -> S(x). exists x: Q(x) -> W(x).
