Consider the following premises. forall x: R(x) <-> W_1(x). exists x: ~W_1(x). forall x: R(x) <-> T(x). Can we infer exists x: ~T(x) from them?
 From forall x: R(x) <-> W_1(x), exists x: ~W_1(x) we can infer exists x: ~R(x). Finally, from forall x: R(x) <-> T(x), exists x: ~R(x) we can infer exists x: ~T(x). Therefore, the answer is yes.
