What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_11: R_11(x_11) -> P(x_11). forall x_11: ~P_11(x_11) or R_11(x_11). forall x_11: Q_11(x_11) -> P(x_11). forall x_11: P(x_11) -> Q(x_11). exists x_11: P_11(x_11) or Q_11(x_11).
forall x_11: R_11(x_11) -> Q(x_11). forall x_11: Q_11(x_11) -> Q(x_11). exists x_11: Q_11(x_11) or R_11(x_11).
