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_2: T_3(y_2) or ~S_1(y_2). forall y_2: R(y_2) -> S_1(y_2). forall y_2: Q_2(y_2) -> R(y_2).
forall y_2: Q_2(y_2) -> S_1(y_2) can be inferred via the universal transitivity rule. forall y_2: S_1(y_2) -> T_3(y_2) can be inferred via the universal rewriting rule.
