Student asked: Given the sentence "A mechanic is working on the underside of a bus that is lifted." can we conclude that "Two kids hang their heads out the window of a moving bus."?
Options:
- yes
- it is not possible to tell
- no

Student asked: Given the sentence "A lady showing off a ring to two other ladies." can we conclude that "The woman is showing off her necklace."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. Woman is a general description while lady is in more detail. Think of a generic woman versus someone of high class. Also a ring and a necklace are two different pieces of jewelry. The answer is no.

Student asked: If "The woman is wearing a purple shirt and runs on the beach." does that mean that "A man is fishing in a boat."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response:
Let's think. A woman who runs on the beach is not the same person as a man fishing in a boat. A woman and a man cannot be the same person. The answer is no.
