Can we conclude from "A group of dogs pull a person on a dog sled up a hill." that "Dogs run around a grassy backyard chasing a red ball."?
Options:
- yes
- no
- it is not possible to tell
Let's solve step-by-step:
Dogs running around a grassy backyard can't be going up a hill. Dogs chasing a ball must be engaged in a different activity than to pull a person on a sled up a hill. The answer is no.
