Detailed 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.
Q: Passage: The Rolling Stone Album Guide (2004) writes: "Frank Zappa dabbled in virtually all kinds of music—and, 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 Varèse 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 genres—rock, jazz, classical, avant-garde and even novelty music—with 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.
