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_3: U_4(x_3) -> T_2(x_3). forall x_3: W(x_3) or U_4(x_3). forall x_3: T_2(x_3) or ~W(x_3). exists x_3: U(x_3).
forall x_3: W(x_3) -> T_2(x_3) can be inferred via the universal rewriting rule.
