Leo: Given the sentence "A man in a striped shirt lifts a log in a playground." can we conclude that "A man is working on building a playground."?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
A man lifting a log in a playground is not necessarily working on building a playground.
Thus, the answer is it is not possible to tell.
