instruction:
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: When Muggs refuses to train for the Golden Gloves match unless he has his own private camp in the country, Danny placates his pal by enlisting members of the Vassey Street Boys' Club in the Civilian Conservation Corps. Arriving at the camp, Muggs refuses to accept the authority of Allen, the leader of the boys, and treats the facility as if it was his own private property. Later, Muggs has a chance to demonstrate his true nature when he risks his own life to save Al from being crushed by a falling tree. The camp captain praises Muggs for his courage, and as a reward, Muggs requests a boxing match with Al. Norton, a small-time boxing promoter, comes to watch the fight, which ends in a draw. Furious at the outcome, Muggs refuses to shake his opponent's hand, an act which earns the enmity of the other boys. When the captain fails to remove the chip from Muggs' shoulder, his daughter, Elaine, tries to reform him through kindness. Meanwhile, Willie, one of the boys, steals one hundred dollars from the camp cash box and confides to Muggs that he needed the money for his poor aunt. To get the money back for Willie, Muggs has Norton arrange a fight, and although he takes a beating in the ring, Muggs earns the one hundred dollars. While returning the money to the cash box, Muggs is caught and accused of theft. He refuses to inform on Willie, though and instead runs away. Danny then forces the truth from Willie, thus proving Muggs' true sportsmanship.
answer:
Who arranges a private camp for Muggs?

Passage: Following the seven performances on the Joshua Tree Tour, U2 did not perform "Mothers of the Disappeared" until 1998, on the fourth leg of the PopMart Tour. It was played at three concerts in Argentina and once in Chile, concluding all four shows. Bono sang "el pueblo vencerá" at the end of each performance. The first rendition was on 5 February 1998 in Buenos Aires, where it was performed with the Madres accompanying them onstage. The song was played by just Bono and the Edge and was set against footage of the Madres on the video screen. At the conclusion of the song, the band members faced the Madres and applauded, an act in which the rest of the audience joined. Part of the performance was later included on the television documentary Classic Albums: The Joshua Tree.The cost of the tickets was too high for many fans in South America, so the band broadcast the 11 February concert in Chile live on television. Knowing that many people in the country would be watching, they played "Mothers of the Disappeared" in place of "Wake Up Dead Man". The stadium in which the concert was held had been used as a prison camp by Pinochet's regime following the coup d'état. Again it was performed solely by Bono and the Edge against footage of the Madres, and they invited the women to join them onstage a second time. The Madres held up photographs of their children and spoke about them briefly during the performance, an act which received a mixed reception from the audience. Bono made a plea to Pinochet, asking him to "tell these women where are the bones of their children.""Mothers of the Disappeared" was performed again on the fourth leg of the Vertigo Tour, on 26 February 2006 in Santiago and 2 March in Buenos Aires. Although it was rehearsed by the full band, it was played only by Bono and the Edge in an arrangement similar to the one from the PopMart Tour. The Edge performed the song on a charango that Chilean President Ricardo Lagos had given to Bono earlier that day. It was played at three concerts on the third leg of the U2 360° Tour in place of "MLK". One performance in Istanbul, Turkey was dedicated to Fehmi Tosun, an ethnic Kurd who was kidnapped in October 1995 and subsequently disappeared. The abduction was witnessed by his wife and daughter; no information regarding his disappearance has ever been released.
For the first time in 30 years, a full band arrangement of "Mothers of the Disappeared" returned to U2's live set for the Joshua Tree Tour 2017, on which the group played The Joshua Tree in sequence in its entirety for each show. Eddie Vedder and Mumford & Sons accompanied U2 on-stage in a performance of the song during a 14 May 2017 show in Seattle.
answer:
What had "el pueblo vencerá" sung after each performance?


question:
Passage: Mesopropithecus is a genus within the sloth lemur family (Palaeopropithecidae), which includes three other genera: Palaeopropithecus, Archaeoindris, and Babakotia. This family in turn belongs to the infraorder Lemuriformes, which includes all the Malagasy lemurs.Mesopropithecus was named in 1905 by Herbert F. Standing using four skulls found at Ampasambazimba. He noted that the animal had characteristics of both Palaeopropithecus and the living sifakas (Propithecus). In 1936, Charles Lamberton defined Neopropithecus globiceps (based on one skull from Tsirave) and N. platyfrons (based on two skulls from Anavoha).  He thought that Neopropithecus was a separate, intermediate genus between Mesopropithecus and Propithecus.  In 1971, paleoanthropologist Ian Tattersall merged N. platyfrons into N. globiceps and Neopropithecus into Mesopropithecus.Until 1986, Mesopropithecus was only known from cranial (skull) remains from central and southern Madagascar, and because these are similar to teeth and skulls of living indriids, particularly those of Verreaux's sifaka (Propithecus verreauxi), Mesopropithecus was often assigned to the family Indriidae.  For example, in 1974, Tattersall and Schwartz labeled Mesopropithecus as a sister group to sifakas.  With the discovery of an associated skeleton of M. dolichobrachion near Ankarana in 1986, it became clear that Mesopropithecus shared distinct traits with sloth lemurs.  Unlike the indriids, but like the sloth lemurs, they had elongated forelimbs and other adaptations for arboreal suspension (hanging in trees), linking them most closely to family Paleaeopropithecidae.  A comparison of these morphological traits between the sloth lemurs and indriids suggest that Mesopropithecus was the first genus to diverge within the sloth lemur family.
answer:

What was labeled as a sister group in 1974?
