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: W_3(x) -> Q(x). exists x: ~P_3(x). forall x: Q(x) -> P_3(x). forall x: T_2(x) -> W_3(x).
exists x: ~Q(x) can be inferred via the existential modus tollens rule. forall x: W_3(x) -> P_3(x) can be inferred via the universal transitivity rule. forall x: T_2(x) -> Q(x) can be inferred via the universal transitivity rule.
