Student: Premise: "Several people are standing on a street corner watching a cartoonist with glasses draw on his sketch pad."
Based on this premise, can we conclude that the hypothesis "Nobody has a sketch pad." is true?
Options:
- yes
- it is not possible to tell
- no.
Teacher: Let's think:
There can be a cartoonist who draws on his sketch pad or nobody has a sketch pad. So the final answer is no.
