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: U(y) or T(y). forall y: U(y) -> P_3(y). forall y: P_3(y) -> R(y). forall y: Q_2(y) -> R(y). forall y: T(y) -> Q_2(y).
forall y: U(y) -> R(y) can be inferred via the universal transitivity rule. forall y: T(y) -> R(y) can be inferred via the universal transitivity rule.
