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 y: T(y) -> W_1(y). forall y: W_1(y) -> Q(y). forall y: Q(y) -> W_1(y).
forall y: T(y) -> Q(y) can be inferred via the universal transitivity rule. forall y: W_1(y) <-> Q(y) can be inferred via the universal biconditional introduction rule. forall y: Q(y) <-> W_1(y) can be inferred via the universal biconditional introduction rule.
