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: exists x_5: S(x_5) -> S_3(x_5). forall x_5: W(x_5) -> Q_5(x_5). forall x_5: Q_5(x_5) -> S(x_5). forall x_5: W(x_5).
forall x_5: Q_5(x_5) can be inferred via the universal modus ponens rule. forall x_5: W(x_5) -> S(x_5) can be inferred via the universal transitivity rule. exists x_5: Q_5(x_5) -> S_3(x_5) can be inferred via the existential transitivity rule.
