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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

Passage: Stephen Thomas Erlewine of AllMusic said that releasing the Spanish-language Fijacion Oral, Vol. 1 after the success of the English-language Laundry Service was a "sharp move", complimenting the album for demonstrating that Shakira "can not only return to her roots, but expand upon them". He described "La Tortura" as a "natural for American radio", and felt that the parent album generated anticipation for the upcoming Oral Fixation, Vol. 2. Writing for PopMatters, Matt Cibula praised the album for its musical departure from Laundry Service, applauding the integration of subtle samples across several songs as "great nods to the sounds of the 1980s". Dave Simpson of The Guardian compared Shakira to a "Latin American Madonna", describing her vocals as reminiscent of "Cher and Hazel O'Connor, produced by Julio Iglesias".Jon Pareles of The New York Times found Shakira's "smart or ambitious" image to be uncharacteristic of a sex symbol. He praised the versatility of her multilingual lyrics and her experimentation in a number of genres, citing the "multiplicity" in "the arrangements, in the mixed emotions of the lyrics, [and] in Shakira's mercurial voice". Writing for Paste, Mark Kemp complimented Shakira for dispelling notions she is "the Latin Britney, the female Ricky Martin [and] the pretty pop tart who sings in Spanish and sounds like Alanis"; he compared the mix of musical elements in Fijacion Oral, Vol. 1 to a Pop-Tart with a "rich and nutritious filling". Tom Townsend of Yahoo! Music called her "the greatest pop star we have", comparing her "consuming artistry" to that of Madonna and Prince. He credited the album for inspiring a revival of pop music, saying that the release proved that the genre "wasn't dead, just sleeping".Shakira's international success was solidified with Fijacion Oral, Vol. 1's strong commercial performance. After it debuted at number 4 on the US Billboard 200 and became the highest-debuting full-length Spanish album in the country, her label Epic Records called her "the biggest female crossover artist in the world". The album is her third-highest-charting release in the nation, behind Laundry Service's peak position at number 3 and Shakira's number 2 peak. According to Billboard, it was the second best-selling Latin album of the decade in the US after Barrio Fino by Daddy Yankee.
