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_3: S_1(x_3) -> W(x_3). forall x_3: P_3(x_3) -> S_1(x_3). forall x_3: P_3(x_3). forall x_3: Q(x_3) -> W(x_3).
forall x_3: S_1(x_3) can be inferred via the universal modus ponens rule. forall x_3: P_3(x_3) -> W(x_3) can be inferred via the universal transitivity rule.
