What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_14: R(x_14). forall x_14: Q_5(x_14). forall x_14: P_14(x_14) -> S(x_14). exists x_14: P_14(x_14) or Q_14(x_14). forall x_14: Q_14(x_14) -> S(x_14).
forall x_14: R(x_14) and Q_5(x_14). forall x_14: Q_5(x_14) and R(x_14). exists x_14: S(x_14).
