What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_3: P_3(x_3). exists x_3: P(x_3). forall x_3: P_3(x_3) -> S_2(x_3).
forall x_3: S_2(x_3). exists x_3: P(x_3) and P_3(x_3). exists x_3: P_3(x_3) and P(x_3).
