Leo: If "People attending a conference with a lecturer." does that mean that "People are attending a conference with a lecturer speaking about dirty blankets."?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:

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 attending a conference with a lecturer is not always speaking about dirty blankets.
Thus, the answer is it is not possible to tell.
