Leo: If "A janitor flashes a smile while he cleans a replica small building with a vacuum cleaner." does that mean that "Janitor smiles at small child while working."?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
Just because a janitor smiles does not mean that he is smiling at a small child.
Thus, the answer is it is not possible to tell.
