Leo: Can we conclude from "A snowboarder in green grinds along the edge of a rail at night." that "A snowboarder is outside at night riding."?
Options:
- yes
- no
- it is not possible to tell
Mei: OK, So, let's think first...
Me:
Grinds along the edge of a rail implies that the snowboarder is riding and is outside.
Thus, the answer is yes.
