Consider the following premises. S_15(a_15) -> q. ~t_3. forall x_15: T(x_15) -> S_15(x_15). q -> t_3. Can we infer T(a_15) from them?
 From forall x_15: T(x_15) -> S_15(x_15) we can infer T(a_15) -> S_15(a_15). From T(a_15) -> S_15(a_15), S_15(a_15) -> q we can infer T(a_15) -> q. From q -> t_3, ~t_3 we can infer ~q. Finally, from T(a_15) -> q, ~q we can infer ~T(a_15), which contradicts T(a_15). Therefore, the answer is no.
