Student asked: Premise: "A skateboarder going off a ramp."
Based on this premise, can we conclude that the hypothesis "A skateboarder is at the skate park." is true?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. Ramps can be found in places other than at the skate park. The answer is it is not possible to tell.

Student asked: If "A boy wearing shorts and a watch kicks a soccer ball next to a picnic table." does that mean that "A boy kicks a soccer ball to a picnic table."?

Student asked: Given the sentence "A closeup shot of a long-haired man playing a red electric guitar." is it true that "A man is playing the violin."?

Student asked: Test for natural language inference.
Premise: "A woman floats with her face out of water in a pool with another woman nearby posing for the camera."

Options:
- yes
- no
- it is not possible to tell
Teacher's response:
Let's think. One cannot float in a pool and hike up the mountain simultaneously. The answer is no.
