What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: forall x_10: Q_10(x_10) -> U(x_10). forall x_5: U(x_5) -> S_5(x_5). forall x_10: S(x_10) or Q_10(x_10). forall x_10: S(x_10) -> U(x_10).
forall x_10: U(x_10) can be inferred via the universal disjunction elimination rule.
