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.
Input: Passage: Grayson's traveling carnival comes to Munich with acts that include high-dive artist Frank Collini and silent strongman Groppo. A local girl named Willi picks the pocket of Joe, who works for the carny, but she ends up being offered a job.
Joe makes romantic advances to Willi, who tries to resist him but can't. Collini asks if she would like to become a part of his act, which involves diving into a flaming tank of water from a great height. He also proposes marriage on Willi's first night as part of the show.
Magazine photographer Bill comes to take their picture as The Great Collinis' fame grows. Collini gives a beating to Joe after catching him with Willi, whereupon he plunges to his death after a rung on his high-dive ladder breaks.
Willi inherits $5,000. Joe spends the night with her; but, next morning, he is gone as is her money. She eventually gets Joe to confess that he sawed Collini's rung in two, deliberately causing his death. When Willi asserts her independence from Joe, he attacks her and tries to strangle her.  Hearing her cries for help, strongman Groppo comes to Willi's rescue, He chases Joe who tries to escape on a Ferris wheel.  Groppo climbs to the top of the wheel and throws Joe off, killing Joe; and Groppo is led away by the police.
Output:
What is the full name of the person who falls off the ladder?
