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 z: T(z) or ~W(z). forall z: S(z) <-> W(z). forall z: W(z) -> S(z). forall z: ~T(z).
forall z: W(z) -> T(z) can be inferred via the universal rewriting rule. forall z: S(z) -> W(z) can be inferred via the universal biconditional elimination rule. forall z: W(z) -> S(z) can be inferred via the universal biconditional elimination rule.
