Student asked: Given the sentence "A fat man wearing a tan t-shirt with black and gray hair brushes his teeth with an electric toothbrush in a room with a calendar on the wall and a lamp on a dresser." can we conclude that "The little boy is combing his hair."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. A fat man isn't a little boy and brushing the teeth is not the same as combing the hair. The answer is no.

Student asked: Test for natural language inference.
Premise: "The little red dog is running a course in front of blue tents."
Hypothesis: "A small red dog competes at a dog show."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell
Teacher's response:
Let's think. Not all dogs are little and red. Just because the little red dog is running a course in front of blue tents does not mean the dog competes at a dog show. The answer is it is not possible to tell.
