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_5: T_2(x_5) -> S_3(x_5). forall x_5: T_2(x_5). forall x_5: S_3(x_5) -> R(x_5). exists x_5: R_3(x_5) -> R(x_5).
forall x_5: S_3(x_5) can be inferred via the universal modus ponens rule. forall x_5: T_2(x_5) -> R(x_5) can be inferred via the universal transitivity rule.
