Leo: If "Old woman in blue striped shirt watches a man and his son target shooting for prizes." does that mean that "A boy and his father are swimming alone."?
Options:
- yes
- it is not possible to tell
- no
Mei: OK, So, let's think first...
Me:
The boy and his father are either target shooting for prizes while being watched by an old woman or they are swimming alone.
Thus, the answer is no.
