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_3: T(z_3) -> S(z_3). exists z_3: T(z_3) or ~S(z_3). forall z_3: ~T(z_3).
exists z_3: S(z_3) -> T(z_3) can be inferred via the existential rewriting rule.
