[Q]: Passage: Bush starred in the 1990 black comedy film Les Dogs, produced by The Comic Strip for BBC television. Bush plays the bride Angela at a wedding set in a post-apocalyptic Britain. In another Comic Strip Presents film, GLC, she produced and sang on the theme song "Ken". The song was written about Ken Livingstone, the leader of the Greater London Council and future mayor of London, who at the time was working with musicians to help the Labour Party garner the youth vote.Bush wrote and performed the song "The Magician", using a fairground-like arrangement, for Menahem Golan's 1979 film The Magician of Lublin. The track was scored and arranged by Michael Kamen. In 1986, she wrote and recorded "Be Kind to My Mistakes" for the Nicolas Roeg film Castaway. An edited version of this track was used as the B-side to her 1989 single "This Woman's Work". In 1988, the song "This Woman's Work" was featured in the John Hughes film She's Having a Baby, and a slightly remixed version appeared on Bush's album The Sensual World. The song has since appeared on television shows, and in 2005 reached number-eight on the UK download chart after featuring in a British television advertisement for the charity NSPCC.In 1999, Bush wrote and recorded a song for the Disney film Dinosaur, but the track was not included on the soundtrack. According to the winter 1999 issue of HomeGround, a Bush fanzine, it was scrapped when Disney asked her to rewrite the song and she refused. Also in 1999, Bush's song "The Sensual World" was featured prominently in Canadian filmmaker Atom Egoyan's film "Felicia's Journey".In 2007, Bush was asked to write a song for The Golden Compass soundtrack which made reference to the lead character, Lyra Belacqua. The song, "Lyra", was used in the closing credits of the film, reached number 187 in the UK Singles Chart and was nominated for the International Press Academy's Satellite Award for original song in a motion picture. According to Del Palmer, Bush was asked to compose the song on short notice and the project was completed in 10 days. 
Question: What is the last name of the person who wrote and recorded "Be Kind to My Mistakes" ?
[A]: Bush.


[Q]: Passage: Bartlett decided to send a team back to establish the exact location of the island that the Anderson party had approached, and to determine if Anderson had actually landed there. An injury to his knee ruled Mamen out from this mission, which was undertaken by ship's steward Ernest Chafe, with the Inuit pair, Kataktovik and Kuraluk. Chafe's group came within 2 miles (3 km) of Herald Island before being stopped by open water. A careful examination through binoculars revealed no signs of the missing party, and Chafe concluded that Anderson and company had not reached the island. Chafe and his party then returned to Shipwreck Camp.Meanwhile, on 4 February, Mackay and his group (Murray and Beuchat, joined by seaman Stanley Morris) announced they were leaving the next day, to seek land. Mackay presented Bartlett with a letter dated 1 February that began: "We, the undersigned, in consideration of the present critical situation, desire to make an attempt to reach the land." The letter requested appropriate supplies, and concluded by emphasising that the journey was on their own initiative and absolving Bartlett from all responsibilities. Bartlett allocated them a sledge, a tent, six gallons of oil, a rifle and ammunition and food for 50 days. They left on 5 February; the last sighting of them was a few days later, by Chafe and the Inuit, returning from their abortive trip to Herald Island. They found Mackay's party struggling to make headway, with some of their provisions lost and clothing and other equipment discarded to lighten their load. Beuchat in particular was in a distressed state, nearly delirious and in the throes of hypothermia. However, the party refused assistance and rejected Chafe's pleas that they return with him to Shipwreck Camp. Thereafter the only hint of their fate was a sailor's scarf belonging to Morris, later found buried in an ice floe. It was assumed that the four had either been crushed by the ice, or had fallen through it. 
Question: What were the last names of the people in Mackay's group?
[A]: Murray.


[Q]: Passage: The search for a singer-actress to play Carmen began in the summer of 1873. Press speculation favoured Zulma Bouffar, who was perhaps the librettists' preferred choice. She had sung leading roles in many of Offenbach's operas, but she was unacceptable to Bizet and was turned down by du Locle as unsuitable. In September an approach was made to Marie Roze, well known for previous triumphs at the Opéra-Comique, the Opéra and in London. She refused the part when she learned that she would be required to die on stage. The role was then offered to Célestine Galli-Marié, who agreed to terms with du Locle after several months' negotiation. Galli-Marié, a demanding and at times tempestuous performer, would prove a staunch ally of Bizet, often supporting his resistance to demands from the management that the work should be toned down. At the time it was generally believed that she and the composer were conducting a love affair during the months of rehearsal.The leading tenor part of Don José was given to Paul Lhérie, a rising star of the Opéra-Comique who had recently appeared in works by Massenet and Delibes. He would later become a baritone, and in 1887 sang the role of Zurga in the Covent Garden premiere of Les pêcheurs de perles. Jacques Bouhy, engaged to sing Escamillo, was a young Belgian-born baritone who had already appeared in demanding roles such as Méphistophélès in Gounod's Faust and as Mozart's Figaro. Marguerite Chapuy, who sang Micaëla, was at the beginning of a short career in which she was briefly a star at London's Theatre Royal, Drury Lane; the impresario James H. Mapleson thought her "one of the most charming vocalists it has been my pleasure to know". However, she married and left the stage altogether in 1876, refusing Mapleson's considerable cash inducements to return. 
Question: What is the last name of the person who had sung leading roles in many of Offenbach's operas?
[A]:
Bouffar.
