What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_1: ~P_1(x_1). forall x_1: S(x_1) <-> W_3(x_1). forall x_1: P_1(x_1) <-> W(x_1). forall x_1: W_3(x_1) <-> W(x_1).
forall x_1: S(x_1) -> W_3(x_1). forall x_1: P_1(x_1) -> W(x_1). forall x_1: W_3(x_1) -> W(x_1). forall x_1: W_3(x_1) -> S(x_1). forall x_1: W(x_1) -> P_1(x_1). forall x_1: W(x_1) -> W_3(x_1). forall x_1: ~W(x_1).
