Leo: Given the sentence "A couple is walking down a busy city street when they pass a bird show." is it true that "A married couple in the middle of the shopping season."?
Mei: OK, So, let's think first...
Me:
A couple is walking down a busy city street when they pass a bird show does not imply they are a married couple in the middle of the shopping season.
Thus, the answer is it is not possible to tell.
