Denny asked: If "A line of people rides an escalator upstairs while an advertisement is featured in the foreground." does that mean that "People are sitting on a blanket in the park."?
Options:
- yes
- it is not possible to tell
- no.
Le: OK, so how can I answer with some explanation?
People who at the park sitting down can not be riding escalator at the same time.
The answer: no.
