Student asked: If "Two people wearing brightly colored protective headgear are in a swimming pool with very choppy water and the person in the foreground has a hand on a yellow and blue ball which is approximately the size of a basketball." does that mean that "The swimmers are in very choppy water and are in danger of drowning even though one has a huge hand."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. Not all hands are huge and swimming in a pool with choppy water does not imply being in danger of drowning. The answer is it is not possible to tell.

Student asked: Premise: "A street performer dressed as a statue stands in the middle of a street."
Hypothesis: "A person imitating a statue scares pedestrians as they cross the road."

Teacher's response:
Let's think. Not all street performers are imitating something. What scares them if he's standing still? Not everyone is going to cross the street. The answer is it is not possible to tell.
