What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y: R_3(y) <-> W(y). forall y: ~R_3(y). forall y: S(y) <-> W(y).
forall y: R_3(y) -> W(y). forall y: S(y) -> W(y). forall y: W(y) -> R_3(y). forall y: W(y) -> S(y). forall y: ~W(y).
