What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall z_3: ~Q(z_3). exists z_3: Q(z_3) -> W(z_3). forall z_3: W(z_3) -> Q(z_3).
forall z_3: ~W(z_3). exists z_3: Q(z_3) <-> W(z_3). exists z_3: W(z_3) <-> Q(z_3).
