Consider the question. Premise: "A black dog runs on green grass with its mouth open."
Based on this premise, can we conclude that the hypothesis "A dog is running with it mouth open to catch a bone." is true?
Options:
- yes
- it is not possible to tell
- no
 If the answer is 'it is not possible to tell'; explain the reasoning:
A dog running with its mouth open is not necessarily trying to catch a bone.
