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: T(y) -> R_2(y). forall y: P(y) or ~P_3(y). forall y: P(y) -> T(y). forall y: R_2(y) -> S(y).
forall y: T(y) -> S(y) can be inferred via the universal transitivity rule. forall y: P(y) -> R_2(y) can be inferred via the universal transitivity rule. forall y: P_3(y) -> P(y) can be inferred via the universal rewriting rule.
