Student asked: Given the sentence "A man with a red jacket and hood on hold onto the bars of a blue bus." is it true that "A man is riding a bus."?
Teacher's response: Let's think. A man holding on to the bars of a blue bus doesn't necessarily mean he is riding the bus. The bus could be stopped. The answer is it is not possible to tell.


Student asked: Premise: "A young performer stands atop a red ball at the circus."
Based on this premise, can we conclude that the hypothesis "A person on a ball falls off." is true?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. A young performer at a circus would not necessarily have to be a person. Standing atop a red ball does not necessarily mean the performer will fall off. The answer is it is not possible to tell.
