Denny asked: Given the sentence "There are groups of people in green or purple shirts gathered outside holding signs and purple balloons." can we conclude that "Group of people gathered outside to celebrate their boss birthday."?
Options:
- yes
- it is not possible to tell
- no.
Le: OK, so how can I answer with some explanation?

Gathering outside does not mean it is to celebrate their boss birthday.
