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: U(x) -> Q_2(x). forall x: T(x). forall x: U_3(x) -> Q_2(x). forall x: T_2(x) -> U(x). forall x: U_3(x) or T_2(x).
forall x: T_2(x) -> Q_2(x) can be inferred via the universal transitivity rule.
