What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_10: R_10(x_10) -> P_9(x_10). forall x_10: Q_10(x_10) -> R_10(x_10). forall x_10: P_9(x_10) -> R_10(x_10). forall x_10: Q(x_10) -> Q_10(x_10). forall x_10: P_9(x_10) -> Q(x_10).
forall x_10: R_10(x_10) -> Q(x_10). forall x_10: Q_10(x_10) -> P_9(x_10). forall x_10: Q(x_10) -> R_10(x_10). forall x_10: P_9(x_10) -> Q_10(x_10). forall x_10: R_10(x_10) <-> P_9(x_10). forall x_10: P_9(x_10) <-> R_10(x_10).
