Consider the question. Can we conclude from "The man works on the roof of the building." that "The man is on the roof."?
Options:
- yes
- no
- it is not possible to tell
 If the answer is 'yes'; explain the reasoning:

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.
