What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_14: P_9(x_14) -> P(x_14). forall x_14: P_6(x_14) or ~P_14(x_14). forall x_14: P_9(x_14). forall x_14: P_14(x_14) or ~P(x_14).
forall x_14: P(x_14). forall x_14: P_14(x_14) -> P_6(x_14). forall x_14: P(x_14) -> P_14(x_14).
