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_9: R(x_9). forall x_9: Q_5(x_9) -> W(x_9). forall x_9: T_1(x_9) -> W(x_9). forall x_9: R(x_9) -> Q_5(x_9).
forall x_9: Q_5(x_9) can be inferred via the universal modus ponens rule. forall x_9: R(x_9) -> W(x_9) can be inferred via the universal transitivity rule.
