Student: Can we conclude from "A group of people building a structure are talking." that "A group of people tear down a structure."?
Options:
- yes
- no
- it is not possible to tell.
Teacher: Let's think:

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.
