Denny asked: Can we conclude from "The boys smiles underwater at the pool." that "Small boys smile and give a thumbs up under water at a public pool."?
Options:
- yes
- no
- it is not possible to tell.
Le: OK, so how can I answer with some explanation?
Boys don't need to give a thumbs up to smile underwater. The pool is not necessarily a public pool.
The answer: it is not possible to tell.
