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.
Example solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: 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.

Problem: Passage: Ravel completed two operas, and worked on three others. The unrealised three were Olympia, La cloche engloutie and Jeanne d'Arc. Olympia was to be based on Hoffmann's The Sandman; he made sketches for it in 189899, but did not progress far. La cloche engloutie after Hauptmann's The Sunken Bell occupied him intermittently from 1906 to 1912, Ravel destroyed the sketches for both these works, except for a "Symphonie horlogere" which he incorporated into the opening of L'heure espagnole. The third unrealised project was an operatic version of Joseph Delteil's 1925 novel about Joan of Arc. It was to be a large-scale, full-length work for the Paris Opera, but Ravel's final illness prevented him from writing it.Ravel's first completed opera was L'heure espagnole (premiered in 1911), described as a "comedie musicale". It is among the works set in or illustrating Spain that Ravel wrote throughout his career. Nichols comments that the essential Spanish colouring gave Ravel a reason for virtuoso use of the modern orchestra, which the composer considered "perfectly designed for underlining and exaggerating comic effects". Edward Burlingame Hill found Ravel's vocal writing particularly skilful in the work, "giving the singers something besides recitative without hampering the action", and "commenting orchestrally upon the dramatic situations and the sentiments of the actors without diverting attention from the stage." Some find the characters artificial and the piece lacking in humanity. The critic David Murray writes that the score "glows with the famous Ravel tendresse".The second opera, also in one act, is L'enfant et les sortileges (1926), a "fantaisie lyrique" to a libretto by Colette. She and Ravel had planned the story as a ballet, but at the composer's suggestion Colette turned it into an opera libretto. It is more uncompromisingly modern in its musical style than L'heure espagnole, and the jazz elements and bitonality of much of the work upset many Parisian opera-goers. Ravel was once again accused of artificiality and lack of human emotion, but Nichols finds "profoundly serious feeling at the heart of this vivid and entertaining work". The score presents an impression of simplicity, disguising intricate links between themes, with, in Murray's phrase, "extraordinary and bewitching sounds from the orchestra pit throughout".Although one-act operas are generally staged less often than full-length ones, Ravel's are produced regularly in France and abroad.
Solution: What is the name of the opera where critics accused the man who completed two operas of artificiality and lack of human emotion?
