What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_8: P_3(x_8) <-> S_1(x_8). exists x_8: W_2(x_8) <-> S_1(x_8). forall x_8: ~P_3(x_8).
forall x_8: P_3(x_8) -> S_1(x_8). exists x_8: W_2(x_8) -> S_1(x_8). forall x_8: S_1(x_8) -> P_3(x_8). exists x_8: S_1(x_8) -> W_2(x_8). forall x_8: ~S_1(x_8).
