Leo: Given the sentence "A man in a white cowboy hat riding a bucking brown horse at a rodeo." is it true that "A cowboy is making money for his family."?
Mei: OK, So, let's think first...
Me:
A man in a white cowboy hat riding a bucking brown horse at a rodeo does not imply that he is making money for his family.
Thus, the answer is it is not possible to tell.
