Denny asked: Given the sentence "Three black dogs playing on the beach." is it true that "The dogs are fast."?.
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.

Dogs do not have to be fast to be playing on the beach.
The answer: it is not possible to tell.
