Student asked: Premise: "Man with hard hat talking on phone."
Based on this premise, can we conclude that the hypothesis "Man smashes his phone on the concrete floor." is true?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. Talking on a phone is a different activity than smashing it. Yelling into a phone while it is being smashed is not really 'talking' on it. The answer is no.
