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.
Q: Passage: The story begins just after the birth of Robert Rabbit. As his parents and friends welcome him into the world, a mysterious old rabbit who walks with a cane greets young Rob and disappears. The old rabbit shows up a few more times throughout Rob's childhood, always disappearing after making comments or inquiries about his talents and attitude. One day, when Rob's parents become endangered by a falling boulder, he sprints toward them and changes into a striped and star-spangled superhero on golden rollerskates. The old rabbit reappears and tells Rob that he is the American Rabbit, capable of changing into superhero form when he sprints and changing back to normal when he says his own name.
Rob decides to try to keep his superpowers a secret and moves to the city. He finds a job as a piano player at the Panda Monium, a nightclub run by a panda named Teddy and a female rabbit named Bunny O'Hare. The club is harassed by a gang of jackals who run a Mafia-style protection racket. When Teddy refuses to buy insurance from them, they return on their motorcycles during a White Brothers show and wreck the club. Bunny and Teddy organize a march and rally the next day, and Walt, the Jackals' well-dressed boss, orders them to ride their motorcycles in the march. They cause a distraction while Walt's buzzard destroys the cables that support a bridge the marchers are crossing, but the American Rabbit stops the bridge from collapsing. Teddy then announces his plans to do a cross-country tour with the White Brothers, which will allow him to raise enough money to rebuild the Panda Monium.
