Question: How long had Manchester United been a club when Duncan Edwards died? Passage 1:Critic Janet Maslin, writing in The New York Times, said of director Kasdan, "he creates the film's most satisfying moments by communicating his own sheer enjoyment in revitalizing scenes and images that are so well-loved." Impressed, she exclaimed, "Silverado is a sweeping, glorious-looking western that's at least a full generation removed from the classic films it brings to mind." Roger Ebert in the Chicago Sun-Times called it "sophisticated" while remarking, "This is a story, you will agree, that has been told before. What distinguishes Kasdan's telling of it is the style and energy he brings to the project." In the San Francisco Chronicle, Peter Stack wrote that the film "delivers elaborate gun-fighting scenes, legions of galloping horses, stampeding cattle, a box canyon, covered wagons, tons of creaking leather and even a High Noonish duel." He openly mused, "How it manages to run the gamut of cowboy movie elements without getting smart-alecky is intriguing." In a mixed review, Gene Siskel of the Chicago Tribune, said the film was "a completely successful physical attempt at reviving the western, but its script would need a complete rewrite for it to become more than just a small step in a full-scale western revival." Another ambivalent review came from Jay Carr of The Boston Globe. He noted that Silverado "plays like a big-budget regurgitation of old Westerns. What keeps it going is the generosity that flows between Kasdan and his actors. It's got benevolent energies, but not the more primal kind needed to renew the standard Western images and archetypes." In an entirely negative critique, film critic Jay Scott of The Globe and Mail said the all too familiar "manipulative Star Wars-style score is the only novelty on tap in Silverado, which has a plot too drearily complicated and arid to summarize". Left equally unimpressed was Dave Kehr of the Chicago Reader. Commenting on director Kasdan's style, he said his "considerable skills as a plot carpenter seem to desert him as soon as the story moves to the town of the title." As far as the supporting cast was concerned, he dryly noted, "none of them assumes enough authority to carry the moral and dramatic center of the film." Giving Silverado 4 out of 5 stars, author Ian Freer of Empire, thought the film was the "kind of picture that makes you want to play cowboys the moment it is over." He exclaimed, "Whereas many of the westerns from the ‘70s try a revisionist take on the genre, Silverado offers a wholehearted embracing of western traditions."
 Passage 2:The most famous former resident of the Priory Estate is Duncan Edwards, who was born two miles away at Holly Hall but moved to 31 Elm Road as a small child and went on to play 18 times for England as well as winning two Football League championships with Manchester United before he died in 1958 at the age of 21 from injuries sustained in the Munich air disaster. As a child, he had attended Priory Primary School and then Wolverhampton Street School. The school is most famous for being the former school (1941 to 1948) of the late Duncan Edwards, the former Manchester United and England footballer. He died aged 21 as a result of the Munich air disaster in 1958. After his death, a stained glass window was dedicated to Edwards at St Francis parish church at the junction of Laurel Road and Poplar Crescent. The church was founded during 1931 and originally based at Priory Hall before the church building on the newly developed housing estate was opened on 10 May 1932.
 Passage 3:The Yasui procedure is a pediatric heart operation used to bypass the left ventricular outflow tract (LVOT) that combines the aortic repair of the Norwood procedure and a shunt similar to that used in the Rastelli procedure in a single operation. It is used to repair defects that result in the physiology of hypoplastic left heart syndrome even though both ventricles are functioning normally. These defects are common in DiGeorge syndrome and include interrupted aortic arch and LVOT obstruction (IAA/LVOTO); aortic atresia-severe stenosis with ventricular septal defect (AA/VSD); and aortic atresia with interrupted aortic arch and aortopulmonary window. This procedure allows the surgeon to keep the left ventricle connected to the systemic circulation while using the pulmonary valve as its outflow valve, by connecting them through the ventricular septal defect. The Yasui procedure includes a modified Damus–Kaye–Stansel procedure to connect the aortic and pulmonary roots, allowing the coronary arteries to remain perfused. It was first described in 1987.

Question: Who piloted the airplane that killed Mulgrew Nunatak in 1979? Passage 1:Carter started his career as an apprentice at Brighton & Hove Albion but failed to make the grade for the first team. He made his first team debut in April 1987 in a 1–1 draw with Blackburn Rovers, coming on as a substitute and almost scoring with his first touch. He subsequently dropped down to the Isthmian League where he spent a season with Billericay Town. He was signed by Fourth Division side Leyton Orient in July 1988 and remained a first team regular in his seven-year spell at the club, which included promotion to the Third Division in his first season with via the play-offs. In June 1995, he joined newly relegated Second Division side Peterborough United for a fee of £25,000. He was a first team regular in his first season with the club but dropped out of the side in his second season as the club narrowly avoided relegation twice. Following his release he spent time on trial at Cambridge United and Wycombe Wanderers, however, both were unsuccessful in earning a full-time contract. He subsequently signed for Welsh Premier League side Barry Town, where he spent two seasons and made a total of sixty league appearances, scoring ten goals. He later joined Southern League Premier side Merthyr Tydfil in 1999 and spent six seasons with the club making over 200 appearances. He was also the club captain. In the summer of 2005 he signed for newly promoted Welsh Premier League side Cardiff Grange Harlequins but only made eight league appearances and the side couldn't avoid relegation at the first attempt.
 Passage 2:Mulgrew Nunatak () is a prominent nunatak, 1,600 m, standing four nautical miles (7 km) east of Tentacle Ridge in the Cook Mountains. Its summit, standing at , is named Peter Crest. The nunatak was first mapped by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58). Both it and its peak were named for Peter D. Mulgrew, a New Zealand adventurer who accompanied Sir Edmund Hillary to the South Pole and served as the chief radio operator at Scott Base. He perished in the Air New Zealand DC10 scenic flight to Ross Island, 28 November 1979, when the airplane crashed near Te Puna Roimata Peak ("spring of tears" peak) on the northeast slope of Mount Erebus, killing all 257 persons aboard.
 Passage 3:The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) From Fort Ross, the northern segment continues overland, forming in part a linear valley through which the Gualala River flows. It goes back offshore at Point Arena. After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.

Question: What modern day country is Chipata part of? Passage 1:Hunzahúa, heir of Idacansás, was a cacique in the sacred valley of the iraca and was chosen by the other caciques of the region to make peace between the battling parties. He became the first zaque of the northern Muisca region based in Hunza, present-day Tunja, and one of his policies was the ban on the use of weapons. According to Muisca scholar Javier Ocampo López, who wrote extensively about the religion and mythology of the Muisca, his mother was named Faravita and his sister Noncetá. Legend tells that Hunzahúa fell in love with his sister and made her his wife when he left Hunza for Chipatá. Faravita, the mother of the zaque, disagreed with the marriage of her two children and attacked the couple, spilling a bowl of chicha. This created the Hunzahúa Well. When Hunzahúa saw what his mother had done, and the Muisca protesting against his incest, he damned Hunza and the surrounding valley. Noncetá gave birth to a son in Susa, but the young boy turned into a rock. The sad couple traveled further, to the Tequendama Falls. Here, they changed into two rocks at either side of the sacred waterfall.
 Passage 2:The Romanoviches (Izyaslavichi of Volhynia)were the line of Roman the Great, descended from Mstislav I of Kiev through his son Iziaslav II of Kiev and his grandson Mstislav II of Kiev, father of Roman the Great. The older Monomakhovychi line that ruled Principality of Volhynia, they were eventually crowned kings of Galicia and Volhynia and ruled until 1323. Romanovychi displaced the older line of Izyaslavychi from Turov and Volhynia as well as Rostyslavychi from Galicia. The last were two brothers of Romanovychi, Andrew and Lev II, who ruled jointly and were slain trying to repel Mongol incursions. The Polish king, Władysław I the Elbow-high, in his letter to the Pope wrote with regret: "The two last Ruthenian kings, that had been firm shields for Poland from the Tatars, left this world and after their death Poland is directly under Tatar threat." Losing their leadership role, Rurikids, however, continued to play a vital role in the Grand Duchy of Lithuania and the later Polish-Lithuanian Commonwealth. Most notably, the Ostrogski family held the title of Grand Hetman of Lithuania and strove to preserve the Ruthenian language and Eastern Orthodoxy in this part of Europe. It is thought that the Drutsk and related princely families may also descend from Roman the Great.
 Passage 3:McKay grew up supporting Heart of Midlothian (Hearts) and joined the club from local side Edinburgh City in July 2010, aged 17. During the 2010–11 season he gained some experience on loan at junior side Penicuik Athletic, winning their Players' Player of the Year award. McKay was included in the first team squad for the first time on 17 December 2011, when he was an unused substitute against Dunfermline. In May 2012, he signed a 12-month contract tying him to the club until at least the summer of 2013. In November McKay was loaned to Second Division side Stenhousemuir on a month's loan deal, he returned to Hearts after making four league appearances. In February 2013, McKay signed a further one-year extension committing him to the club until the summer of 2014. On 10 March 2013, McKay made his first team debut coming on as a 38th-minute substitute at Easter Road in a Scottish Premier League match against Hibernian, replacing the injured Fraser Mullen in a 0–0 draw. Throughout the pre-season of 2014–15 season McKay was given the opportunity to captain his boyhood club by head coach Robbie Neilson when club captain Danny Wilson was not on the field. McKay played less frequently during the 2014–15 season, as he was unable to break a defensive partnership of Wilson and Alim Ozturk.
