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: exists x_10: U(x_10) or T(x_10). forall x_10: P_10(x_10). forall x_10: P_10(x_10) -> R(x_10). forall x_10: U(x_10) -> S(x_10). forall x_10: T(x_10) -> S(x_10).
forall x_10: R(x_10) can be inferred via the universal modus ponens rule. exists x_10: S(x_10) can be inferred via the existential disjunction elimination rule.
