Student: Premise: "A group of construction workers going down a flight of stairs."
Based on this premise, can we conclude that the hypothesis "Men and women walked down the stairs." is true?
Options:
- yes
- it is not possible to tell
- no.
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.

The group of constructions workers doesn't necessarily consist of both men and women. So the final answer is it is not possible to tell.
