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_4: W(x_4) and U_2(x_4). u.
forall x_4: W(x_4) can be inferred via the universal simplification rule. forall x_4: U_2(x_4) can be inferred via the universal simplification rule.
