Given the task definition, example input & output, solve the new input case.
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.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input case for you: Passage: Young Judy Bellaire has trouble fitting in at school, causing trouble by introducing her jazzy style into music class and being expelled as a result. Returning home to her dysfunctional and financially challenged family, where her playwright father, actress mother, and beautiful elder sister, Sylvia compete for attention along with the funny Russian maid, Olga and the hunky cook, Ricky, who is not-so-secretly in love with Sylvia. Judy foils her father's attempt to ship her off to Europe by escaping from the ship and then trying out for a musical show as a blackface singer, taking advantage of her love of jazz to enchant the show's producer, who hires her and makes her a star of his new show. Meanwhile, Ricky cuts a record, musically expressing his love for Sylvia. Nevertheless, Sylvia is forced into engagement with another man.
When the distraught parents discover their younger daughter is appearing in a musical show, Sylvia rejoins her love, who is also appearing in the show. Finally, all the cast members are reunited, including the Russian maid, who finds her lost love, Boris. The movie's happy ending includes an extravagant stage piece with gorgeously attired chorus girls, happily reunited parents and child, and the happy kiss between Sylvia and Ricky, who is now the producer of a successful musical show.
Output:
What day job does the man who writes a song for Sylvia do?
