What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_10: P_10(x_10) or Q_7(x_10). forall x_10: Q_7(x_10) -> R(x_10). exists x_10: P_10(x_10) -> Q_10(x_10). forall x_10: R_4(x_10). forall x_10: Q_10(x_10) -> R(x_10).
exists x_10: P_10(x_10) -> R(x_10).
