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_6: U(x_6) and S(x_6). forall x_6: T_3(x_6) or ~U(x_6).
forall x_6: U(x_6) can be inferred via the universal simplification rule. forall x_6: S(x_6) can be inferred via the universal simplification rule. forall x_6: U(x_6) -> T_3(x_6) can be inferred via the universal rewriting rule.
