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.

Passage: Twist's mother dies in childbirth in the middle of nowhere. Fearing blame, the locals bury her in an unmarked grave and drop the baby at a rural orphanage, where he is named Twist.
Growing up in the dusty wastes of the Swartland, sold from orphanage into child labour on the farms, and later to a rural undertaker, Twist finally takes his fate into his own hands and escapes to Cape Town. Wide eyed at the wonders of the city, he falls in with Fagin - an ancient Ethiopian, Rastafarian, who runs a network of child thieves. His new friend Dodger teaches him the tricks of the trade, but the inexperienced Twist is caught trying to steal from Ebrahim Bassedien.
Although neither understand it, there is a strange affinity between this old man - who has lost his daughter - and the young boy who never knew his mother. Bassedien takes the little stroller in and for a moment it seems that the trauma is over - as the little boy encounters love for the first time in his short and brutal life.
Enter Monks - the only person who knows Twist's true identity. He is paying Fagin to keep the little boy marginalised. If he ends up in jail or dead on the street, so much the better, for Monks stands to lose his inheritance if anybody ever discovers that Twist is Bassedien's grandson.
The brutal gangster Bill Sykes, and his prostitute girlfriend, Nancy, steal Twist back for Fagin, and the struggle for a little boy's soul begins in earnest.
What person never knew his mother?

Passage: The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai. The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier.
The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janacek operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood considered it an elementary rule that "you must not carry the name of one theatre if you are playing in another one." Covent Garden, protective of its status, objected to the suggestion that the Sadler's Wells company should be called "The British National Opera" or "The National Opera", although neither Scottish Opera nor the Welsh National Opera opposed such a change. Eventually the British government decided the matter, and the title "English National Opera" was approved. The company's board adopted the new name in November 1974. In 1977, in response to demand for more opera productions in English provincial cities, a second company was established. It was based at Leeds in northern England, and was known as ENO North. Under Harewood's guidance, it flourished, and in 1981 it became an independent company, Opera North.
What name did the company that was titled "Sadler's Wells Opera" eventually change its name to?

Passage: The Rolling Stone Album Guide (2004) writes: "Frank Zappa dabbled in virtually all kinds of musicand, whether guised as a satirical rocker, jazz-rock fusionist, guitar virtuoso, electronics wizard, or orchestral innovator, his eccentric genius was undeniable." Even though his work drew inspiration from many different genres, Zappa was seen as establishing a coherent and personal expression.
In 1971, biographer David Walley noted that "The whole structure of his music is unified, not neatly divided by dates or time sequences and it is all building into a composite". On commenting on Zappa's music, politics and philosophy, Barry Miles noted in 2004 that they cannot be separated: "It was all one; all part of his 'conceptual continuity'."
Guitar Player devoted a special issue to Zappa in 1992, and asked on the cover "Is FZ America's Best Kept Musical Secret?" Editor Don Menn remarked that the issue was about "The most important composer to come out of modern popular music".Among those contributing to the issue was composer and musicologist Nicolas Slonimsky, who conducted premiere performances of works of Ives and Varese in the 1930s. He became friends with Zappa in the 1980s, and said, "I admire everything Frank does, because he practically created the new musical millennium. He does beautiful, beautiful work ... It has been my luck to have lived to see the emergence of this totally new type of music."Conductor Kent Nagano remarked in the same issue that "Frank is a genius. That's a word I don't use often ... In Frank's case it is not too strong ... He is extremely literate musically. I'm not sure if the general public knows that." Pierre Boulez told Musician magazine's posthumous Zappa tribute article that Zappa "was an exceptional figure because he was part of the worlds of rock and classical music and that both types of his work would survive."In 1994, jazz magazine DownBeat's critics poll placed Zappa in its Hall of Fame. Zappa was posthumously inducted into the Rock and Roll Hall of Fame in 1995. There, it was written that "Frank Zappa was rock and roll's sharpest musical mind and most astute social critic. He was the most prolific composer of his age, and he bridged genresrock, jazz, classical, avant-garde and even novelty musicwith masterful ease". He received the Grammy Lifetime Achievement Award in 1997. He was ranked number 36 on VH1's 100 Greatest Artists of Hard Rock in 2000.
What is the name of the publication that Nicolas Slonimsky contributed to?
