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: Q(y) -> R(y). forall y: U_2(y) -> Q(y). R(h_4) -> p.
forall y: U_2(y) -> R(y) can be inferred via the universal transitivity rule.
