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: R_6(x_10) or ~U(x_10). forall x_10: Q_10(x_10) -> Q_6(x_10). forall x_10: U(x_10). forall x_10: Q_6(x_10) -> R_6(x_10).
forall x_10: Q_10(x_10) -> R_6(x_10) can be inferred via the universal transitivity rule. exists x_10: U(x_10) -> R_6(x_10) can be inferred via the existential rewriting rule.
