Student asked: Premise: "A slim woman looks at the camera while she walks."
Hypothesis: "A heavy set woman is sitting on a bench."
Is the hypothesis entailed by the premise?

- yes
- it is not possible to tell
- no
Teacher's response: Let's think. The slim woman isn't a heavy set woman. The woman walks so isn't sitting down. The answer is no.

Student asked: Premise: "A crowd of people looking towards a person in a gorilla costume inside a building."
Based on this premise, can we conclude that the hypothesis "The gorilla is in a zoo with other animals." is true?
Options:
- yes

- no
Teacher's response: Let's think. The people and the person in costume are humans and not the same species as the gorilla or the other animals. The answer is no.

Student asked: Given the sentence "A woman sings to a group of people holding their hands up." can we conclude that "A dentist is working on a patient."?
Options:
- yes
- it is not possible to tell
- no
