Question: When did the state entitiy where Sakic was born dissolve? Passage 1:Retford's officially designated BBC Local Radio station in terms of radio coverage is BBC Radio Sheffield. However, editorially, local news coverage is covered on BBC Radio Nottingham's radio and Internet outlets, despite Retford being outside the official coverage area of both BBC Radio Nottingham's FM and DAB signals. Trax FM also editorially covers the town of Retford, although its Ofcom designated FM coverage area only covers the Doncaster area, Worksop and rural areas west of Retford, Retford is covered on DAB via the Sheffield multiplex. Hallam FM's and Greatest Hits South Yorkshire's AM signals also cover the town of Retford. National analogue FM radio services from the BBC and Classic FM are broadcast from the Holme Moss transmitting station in West Yorkshire. Digital Radio services come primarily from the Clarborough transmitter outside of Retford for the Sheffield and Digital One multiplexes, Clifton transmitter near Doncaster for the BBC National DAB multiplex and the Belmont, High Hunsley (near Hull) and Tapton Hill (Sheffield), Waltham and Emley Moor transmitters for the Sound Digital multiplex.
Passage 2:Dinko Sakic (8 September 1921 20 July 2008) was a Croatian fascist leader and war criminal who commanded the Jasenovac concentration camp in the Independent State of Croatia (NDH) from April to November 1944, during World War II. Born in the village of Studenci, near the town of Imotski in what was then the Kingdom of Serbs, Croats and Slovenes, he became a member of the fascist Ustase at a young age. When the Axis powers occupied the Kingdom of Yugoslavia in April 1941, Sakic, aged 19, joined the administration in Jasenovac. He became the camp's assistant commander the following year, and married Nada Luburic, the half-sister of concentration camp commander Vjekoslav "Maks" Luburic, in 1943. This marriage, as well as his fanatic support for Ustase leader Ante Pavelic, led to Sakic's appointment as commander of Jasenovac in April 1944. He was charged in the deaths of an estimated 2,000 people who died during his six months of command at the concentration camp.
Passage 3:The Mustang's success left General Motors unprepared. Chrysler introduced the Plymouth Barracuda a few weeks before the Mustang, and although it was later redesigned as a distinct "pony car", it was initially a modified Plymouth Valiant. However, the "fish car" did not enjoy as strong a market demand as Ford's "pony". General Motors executives thought the rear-engined Chevrolet Corvair Monza would compete against the Mustang, but it also sold poorly by comparison. The Monza performed well, but lacked a V8 engine and its reputation was tarnished by Ralph Nader in his book Unsafe At Any Speed. It took GM until the 1967 model year to counter with the Chevrolet Camaro and Pontiac Firebird. Lincoln-Mercury joined the competition in 1966 with the Mercury Cougar, an "upmarket Mustang" and subsequent Motor Trend Car of the Year. In 1967, American Motors (AMC) introduced the Javelin, an image changing "standout" four-place pony car. In 1969, the Dodge Challenger, a version of the Plymouth Barracuda platform, was last to join the pony car race. This genre of small, sporty automobiles is often referred to as the "pony car" because of the Ford Mustang that established this market segment.

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 DamusKayeStansel procedure to connect the aortic and pulmonary roots, allowing the coronary arteries to remain perfused. It was first described in 1987.

He served as Ambassador Extraordinary and Plenipotentiary of the Sovereign Military Order of Malta to the Slovak Republic from December 2009 to March 2013. He previously served as a United Nations official for 32 years, most recently as the Resident Coordinator of the United Nations system in Ukraine, from 30 September 2004 until 31 March 2009, and previously in the same capacity in Serbia-Montenegro. In early 2012, he was appointed to the Council of the Order of Clans of Ireland (under the patronage of the President of Ireland), and was elected its Chancellor in May 2014 .

Passage 2:Jimmie Giles, Jr. (born November 8, 1954) is a former professional American football player who was drafted by the Houston Oilers in the third round of the 1977 NFL Draft. A , 238lb tight end from Alcorn State University, Giles played in 13 NFL seasons from 1977 to 1989. A four-time Pro Bowl selection, Giles's career flourished as a member of the Tampa Bay Buccaneers during the early and mid-1980s, despite being used mainly as a blocker during several seasons in which he fell into disfavor with the coaching staff. Giles' benching coincided with a training-camp holdout, the first in Buccaneers history by a player under contract, and the difficult Doug Williams negotiations that resulted in his departure for the USFL. Giles' four touchdowns against the Miami Dolphins on October 20, 1985, tied Earl Campbell's record for the most touchdowns by a Dolphins opponent, and is still (as of 2017) the Buccaneers' single-game record; despite this, the Dolphins would win 41-38. Dolphins coach Don Shula said of the performance, "I can't remember any tight end dominating us that way". Buccaneer teammate Gerald Carter said that Giles could have been "one of the best all-time tight ends, if they'd used him more". In 1988 with the Philadelphia Eagles, he caught a touchdown on one of the most memorable plays in Monday Night Football. Quarterback Randall Cunningham escaped a tackle from Giants linebacker Carl Banks and threw a touchdown to Giles.
Passage 3:He was born in 1745 in Melpeia of Messinia. He developed an early anti-Ottoman activity and in 1770 he participated in the Orlov Revolt. He was a friend of Theodoros Kolokotronis father, Konstantinos. Later, he participated in the preparation of the Greek War of Independence in Messenia and when that begun, he was at the side of Theodoros Kolokotronis, whom he followed in the military operations in Arcadia. Despite his advanced age, he participated in the Battle of Valtetsi in May 1821 as the head of the fighters of Androusa and Leontari. Positioned on the western bastion of the Greek camp together with Ioannis Mavromichalis, P. Kefalas and Dimitrios Papatsonis, he was distinguished for the repulse of the repeated attacks of the Ottoman cavalry. Later he participated in the siege and conquest of Tripolitsa. In 1822, he participated in the operations against the expeditionary force of Mahmud Dramali Pasha. For his contribution, he was named a chiliarch in 1823. During the Greek civil wars of 182425, he supported Kolokotronis's side and for that, he was arrested and jailed by the government forces of the Georgios Kountouriotis in the monastery of Prophet Elias on Hydra Island. Soon after his release in May 1825, he became a general and took part in the operations against Ibrahim Pasha of Egypt.
