Detailed Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Problem:Passage: In the Hundred Acre Wood, Tigger searches for someone to bounce with him, but all of his friends are too busy getting ready for the upcoming winter. While he searches for a playmate, Tigger inadvertently destroys Eeyore's house with a boulder. He later damages the complex pulley system that Rabbit has rigged up to remove the boulder, much to the latter's frustration. The rest of Tigger's friends say that they are not quite as bouncy as he is because they are not Tiggers like him. Tigger sadly wanders off in loneliness, wishing there was somebody else like him.
Wanting to play with Tigger, Roo asks if Tigger has a Tigger family he could bounce with. Tigger is fascinated by the idea, and the two go to visit Owl for advice on finding Tigger's family. Owl shows them portraits of his own family and mentions the concept of family trees; Tigger accidentally knocks the portraits over. When he quickly hangs them back up, all of Owl's ancestors appear to be perched on a single tree. Tigger concludes that his family tree must be a real tree, and he and Roo go searching for it.
After searching the wood without turning up any giant, Tigger-striped trees, Tigger and Roo go back to Tigger's house to search for clues to his family's whereabouts. Tigger teaches Roo the awesome Whoop-de-Dooper-Loop-de-Looper-Alley-Ooper Bounce. They find a heart-shaped locket that Tigger hopes will contain a picture of his family, but it is empty. Roo suggests Tigger try writing a letter to his family, which Tigger does.
