Student asked: Premise: "A group of people are walking in single file at an exhibit."
Based on this premise, can we conclude that the hypothesis "People walk single file at an exhibit." is true?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. Sentence 2 is a simplified description of people walking past an exhibit. The answer is yes.

Student asked: Premise: "An elderly man clad in gray slacks and a white button shirt is sitting on a rounded step next to a full bag."
Hypothesis: "A man is delivering crocheries."
Do we know that the hypothesis entailed by the premise?
Teacher's response: Let's think. A man can have a bag and not be delivering crocheries. The answer is it is not possible to tell.

Student asked: Premise: "Two girls eat sprinkle covered ice creams at a park table outside."
Based on this premise, can we conclude that the hypothesis "Two girls are friends and they are eating ice cream together outside at the park." is true?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. The two girls are not necessarily friends and just because they are both eating ice cream does not necessarily mean they are doing it together. The answer is it is not possible to tell.

Student asked: Given the sentence "A man in yellow polo shirt is walking in the crosswalk." can we conclude that "The cars are stopping so the man can walk."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response:
Let's think. The cars could have stopped anywhere and not just on the crosswalk so that the man could walk. The answer is it is not possible to tell.
