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: Zappa's relationship with long-time manager Herb Cohen ended in 1976. Zappa sued Cohen for skimming more than he was allocated from DiscReet Records, as well as for signing acts of which Zappa did not approve. Cohen filed a lawsuit against Zappa in return, which froze the money Zappa and Cohen had gained from an out-of-court settlement with MGM over the rights of the early Mothers of Invention recordings. It also prevented Zappa having access to any of his previously recorded material during the trials. Zappa therefore took his personal master copies of the rock-oriented Zoot Allures (1976) directly to Warner Bros., thereby bypassing DiscReet.In the mid-1970s Zappa prepared material for Läther (pronounced "leather"), a four-LP project. Läther encapsulated all the aspects of Zappa's musical styles—rock tunes, orchestral works, complex instrumentals, and Zappa's own trademark distortion-drenched guitar solos. Wary of a quadruple-LP, Warner Bros. Records refused to release it. Zappa managed to get an agreement with Phonogram Inc., and test pressings were made targeted at a Halloween 1977 release, but Warner Bros. prevented the release by claiming rights over the material. Zappa responded by appearing on the Pasadena, California radio station KROQ, allowing them to broadcast Läther and encouraging listeners to make their own tape recordings. A lawsuit between Zappa and Warner Bros. followed, during which no Zappa material was released for more than a year. Eventually, Warner Bros. issued different versions of much of the Läther material in 1978 and 1979 as four individual albums (five full-length LPs) with limited promotion.Although Zappa eventually gained the rights to all his material created under the MGM and Warner Bros. contracts, the various lawsuits meant that for a period Zappa's only income came from touring, which he therefore did extensively in 1975–77 with relatively small, mainly rock-oriented, bands. Drummer Terry Bozzio became a regular band member, Napoleon Murphy Brock stayed on for a while, and original Mothers of Invention bassist Roy Estrada joined. Among other musicians were bassist Patrick O'Hearn, singer-guitarist Ray White and keyboardist/violinist Eddie Jobson. In December 1976, Zappa appeared as a featured musical guest on the NBC television show Saturday Night Live. Zappa's song "I'm the Slime" was performed with a voice-over by SNL booth announcer Don Pardo, who also introduced "Peaches En Regalia" on the same airing. In 1978, Zappa served both as host and musical act on the show, and as an actor in various sketches. The performances included an impromptu musical collaboration with cast member John Belushi during the instrumental piece "The Purple Lagoon". Belushi appeared as his Samurai Futaba character playing the tenor sax with Zappa conducting.

Passage: Rebuilding was rapid and performed on a grand scale. Rejecting calls to completely remake the street grid, San Franciscans opted for speed. Amadeo Giannini's Bank of Italy, later to become Bank of America, provided loans for many of those whose livelihoods had been devastated. The influential San Francisco Planning and Urban Research Association or SPUR was founded in 1910 to address the quality of housing after the earthquake. The earthquake hastened development of western neighborhoods that survived the fire, including Pacific Heights, where many of the city's wealthy rebuilt their homes. In turn, the destroyed mansions of Nob Hill became grand hotels. City Hall rose again in splendid Beaux Arts style, and the city celebrated its rebirth at the Panama-Pacific International Exposition in 1915.It was during this period San Francisco built some of its most important infrastructure. Civil Engineer Michael O'Shaughnessy was hired by San Francisco Mayor James Rolph as chief engineer for the city in September 1912 to supervise the construction of the Twin Peaks Reservoir, the Stockton Street Tunnel, the Twin Peaks Tunnel, the San Francisco Municipal Railway, the Auxiliary Water Supply System, and new sewers. San Francisco's streetcar system, of which the J, K, L, M, and N lines survive today, was pushed to completion by O'Shaughnessy between 1915 and 1927. It was the O'Shaughnessy Dam, Hetch Hetchy Reservoir, and Hetch Hetchy Aqueduct that would have the largest effect on San Francisco. An abundant water supply enabled San Francisco to develop into the city it has become today.
In ensuing years, the city solidified its standing as a financial capital; in the wake of the 1929 stock market crash, not a single San Francisco-based bank failed. Indeed, it was at the height of the Great Depression that San Francisco undertook two great civil engineering projects, simultaneously constructing the San Francisco–Oakland Bay Bridge and the Golden Gate Bridge, completing them in 1936 and 1937, respectively. It was in this period that the island of Alcatraz, a former military stockade, began its service as a federal maximum security prison, housing notorious inmates such as Al Capone, and Robert Franklin Stroud, the Birdman of Alcatraz. San Francisco later celebrated its regained grandeur with a World's fair, the Golden Gate International Exposition in 1939–40, creating Treasure Island in the middle of the bay to house it.

Passage: Most of Melodifestivalen's rules are dictated by those of the Eurovision Song Contest.  However, regulations have been introduced by the Swedish broadcasters. The competition's official rules are released by SVT early in preparation for each year's Melodifestival, to ensure any changes are noted by songwriters and performers.
There was a limit of six people on stage for each performance. This included the Melodifestivalen choir (huskören, literally "the house choir"), a five-person group of flexible backing singers used by most participants. Artists could use some or all of the back-up singers, or use their own group. All vocals had to be completely live; human voices were not allowed on backing tracks. However, from 2009, the number of performers allowed on stage was eight, and voices were allowed on backing tracks. A live orchestra was used every year from the event's debut to 2000, except 1985 and 1986. Two orchestras were used between 1960 and 1963, a large orchestra and Göte Wilhelmsons kvartett, a jazz quartet. Since 2001, participants have performed to backing tracks.
Entries cannot be publicly broadcast until the semi-finals are previewed on radio. Entries eliminated in the semi-finals may be broadcast as soon as the semi-final has finished. An embargo is placed on songs that qualify for the later rounds until the previews for the Second Chance are broadcast. After this, restrictions on the broadcast of contestant songs are lifted.Broadcasters sometimes make sweeping changes to winning songs before they go to Eurovision. For example, at Melodifestivalen 1961, Siw Malmkvist won with "April, April". Performing after her victory, she stumbled on the lyrics of the song and laughed out loud. The press criticised this as childish. SR replaced her with Lill-Babs for the Eurovision Song Contest. The 1987 winner "Fyra bugg och en Coca Cola", performed by Lotta Engberg, is another example; the song's title was changed to "Boogaloo" for Eurovision, as use of a brand name was against the Contest's rules. This name was chosen as Sweden's two previous Eurovision winners had also included the suffix "-loo".Until 1999, competing songs were only permitted in Swedish, apart from 1965, 1973, 1974, 1975. This did not stop most winning entries recording English (and other language) versions of their songs. Since the abolition of Eurovision's language restrictions in 1999, regardless of the performance language at Melodifestivalen, every Swedish entry has been in English. Spanish, French, Greek, Italian, Portuguese, Bosnian and Persian are among the other languages to have featured. Cameron Cartio's entry in Melodifestivalen 2005 was performed in a constructed language.
