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_8: Q_3(x_8) -> S_4(x_8). forall x_8: U_4(x_8) -> S_4(x_8). forall x_8: R(x_8) -> Q_3(x_8). forall x_8: P_8(x_8) or T(x_8). forall x_8: ~T(x_8) or U_4(x_8). forall x_8: ~P_8(x_8) or R(x_8).
forall x_8: R(x_8) -> S_4(x_8) can be inferred via the universal transitivity rule. forall x_8: T(x_8) or R(x_8) can be inferred via the universal resolution rule.
