Problem: Background: The Mothers of Invention were an American rock band from California that served as the backing musicians for Frank Zappa. Formed in 1964, their work is marked by the use of sonic experimentation, innovative album art, and elaborate live shows. Originally an R&B band called the Soul Giants, the band's first lineup included Ray Collins, David Coronado, Ray Hunt, Roy Estrada and Jimmy Carl Black. Zappa was asked to take over as the guitarist following a fight between Collins and Coronado, the band's original saxophonist/leader.
Context: Later in 1970, Zappa formed a new version of the Mothers (from then on, he mostly dropped the "of Invention"). It included British drummer Aynsley Dunbar, jazz keyboardist George Duke, Ian Underwood, Jeff Simmons (bass, rhythm guitar), and three members of the Turtles: bass player Jim Pons, and singers Mark Volman and Howard Kaylan, who, due to persistent legal and contractual problems, adopted the stage name "The Phlorescent Leech and Eddie", or "Flo & Eddie". This version of the Mothers debuted on Zappa's next solo album Chunga's Revenge (1970), which was followed by the double-album soundtrack to the movie 200 Motels (1971), featuring the Mothers, the Royal Philharmonic Orchestra, Ringo Starr, Theodore Bikel, and Keith Moon. Co-directed by Zappa and Tony Palmer, it was filmed in a week at Pinewood Studios outside London. Tensions between Zappa and several cast and crew members arose before and during shooting. The film deals loosely with life on the road as a rock musician. It was the first feature film photographed on videotape and transferred to 35 mm film, a process which allowed for novel visual effects. It was released to mixed reviews. The score relied extensively on orchestral music, and Zappa's dissatisfaction with the classical music world intensified when a concert, scheduled at the Royal Albert Hall after filming, was canceled because a representative of the venue found some of the lyrics obscene. In 1975, he lost a lawsuit against the Royal Albert Hall for breach of contract. After 200 Motels, the band went on tour, which resulted in two live albums, Fillmore East - June 1971 and Just Another Band From L.A.; the latter included the 20-minute track "Billy the Mountain", Zappa's satire on rock opera set in Southern California. This track was representative of the band's theatrical performances in which songs were used to build up sketches based on 200 Motels scenes as well as new situations often portraying the band members' sexual encounters on the road.
Question: What led the band to get back together?
Answer: due to persistent legal and contractual problems, adopted the stage name "The Phlorescent Leech and Eddie", or "Flo & Eddie".

Problem: Background: David William Donald Cameron (; born 9 October 1966) is a British politician who was Prime Minister of the United Kingdom from 2010 to 2016 and Leader of the Conservative Party from 2005 to 2016. He was Member of Parliament (MP) for Witney from 2001 to 2016. Cameron identifies as a One-Nation Conservative, and has been associated with both economically liberal and socially liberal policies. Born in London to wealthy upper middle-class parents, Cameron was educated at Heatherdown School, Eton College, and Brasenose College, Oxford.
Context: After Lamont was sacked, Cameron remained at the Treasury for less than a month before being specifically recruited by Home Secretary Michael Howard. It was commented that he was still "very much in favour" and it was later reported that many at the Treasury would have preferred Cameron to carry on. At the beginning of September 1993, Cameron applied to go on Conservative Central Office's list of Prospective Parliamentary Candidates. Cameron was much more socially liberal than Howard but enjoyed working for him. According to Derek Lewis, then Director-General of Her Majesty's Prison Service, Cameron showed him a "his and hers list" of proposals made by Howard and his wife, Sandra. Lewis said that Sandra Howard's list included reducing the quality of prison food, although Sandra Howard denied this claim. Lewis reported that Cameron was "uncomfortable" about the list. In defending Sandra Howard and insisting that she made no such proposal, the journalist Bruce Anderson wrote that Cameron had proposed a much shorter definition on prison catering which revolved around the phrase "balanced diet", and that Lewis had written thanking Cameron for a valuable contribution. During his work for Howard, Cameron often briefed the media. In March 1994, someone leaked to the press that the Labour Party had called for a meeting with John Major to discuss a consensus on the Prevention of Terrorism Act. After an inquiry failed to find the source of the leak, Labour MP Peter Mandelson demanded assurance from Howard that Cameron had not been responsible, which Howard gave. A senior Home Office civil servant noted the influence of Howard's Special Advisers, saying previous incumbents "would listen to the evidence before making a decision. Howard just talks to young public school gentlemen from the party headquarters."
Question: Why did he talk to them?
Answer:
During his work for Howard, Cameron often briefed the media.
