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 x_2: T(x_2) -> Q_2(x_2). forall x_2: Q_2(x_2) -> R_2(x_2). forall x_2: R_2(x_2) -> T(x_2).
forall x_2: T(x_2) -> R_2(x_2) can be inferred via the universal transitivity rule. forall x_2: Q_2(x_2) -> T(x_2) can be inferred via the universal transitivity rule. forall x_2: R_2(x_2) -> Q_2(x_2) can be inferred via the universal transitivity rule.
