Come up with a question and stream of consciousness reasoning that would justify this answer: it is not possible to tell
The question is: Can we conclude from "An elder man with a long gray beard riding on the bus." that "The old man is riding the crowded bus."?
Options:
- yes
- no
- it is not possible to tell
Stream of consciousness: The man on the bus may not be riding on a crowded bus. There may not be any other passengers on the bus.
