Denny asked: Given the sentence "A group of people listening to a speech or presentation near the front of the room." is it true that "The people in the back can't hear."?.
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.

People in the back are not certain to not be able to hear.
The answer: it is not possible to tell.
