Consider the following premises. p_8 <-> s. forall z: T(z) -> W_1(z). W_1(c) <-> s. ~p_8. Can we infer ~T(c) from them?
 From forall z: T(z) -> W_1(z) we can infer T(c) -> W_1(c). From p_8 <-> s, ~p_8 we can infer ~s. From W_1(c) <-> s, ~s we can infer ~W_1(c). Finally, from T(c) -> W_1(c), ~W_1(c) we can infer ~T(c). Therefore, the answer is yes.
