Bob: Hey, look! Whose schoolbag do you think this is?
Anna: I don’t know. Look, here’s a school T-shirt.
Bob: Well then, the person must go to our school. Oh! Here is a hair band, so the person can’t be a boy.
Anna: It could be Mei’s hair band. She has long hair.
Bob: Or the hair band might belong to Linda. She was at the picnic, wasn’t she?
Anna: Yes, she was. But then the schoolbag could belong to Rita. She’s always forgetting things.
Bob: Oh, look! Tennis balls.
Anna: Then it must be Linda’s schoolbag. She has long hair and she’s on the tennis team.
Bob: You’re right!
