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 z: Q(z) -> P(z). forall z: T(z) -> Q(z). forall z: U(z) -> T(z).
forall z: U(z) -> Q(z) can be inferred via the universal transitivity rule. exists z: T(z) -> P(z) can be inferred via the existential transitivity rule.
