Denny asked: Given the sentence "A brown bird is sitting on a tree branch." is it true that "A brown bird is sitting in a nest on a tree branch."?.
Le: OK, so how can I answer with some explanation?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Sitting on a tree branch does not imply it is sitting in a nest.
The answer: it is not possible to tell.
