Consider the following premises. p -> Q(a_12). Q(a_12) -> p. forall x: T(x) -> Q(x). Can we infer T(a_12) -> p from them?
 From forall x: T(x) -> Q(x) we can infer T(a_12) -> Q(a_12). From Q(a_12) -> p, p -> Q(a_12) we can infer Q(a_12) <-> p. From Q(a_12) <-> p we can infer Q(a_12) -> p. Finally, from T(a_12) -> Q(a_12), Q(a_12) -> p we can infer T(a_12) -> p. Therefore, the answer is yes.
