[EX Q]: 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 Šakić (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 Ustaše at a young age. When the Axis powers occupied the Kingdom of Yugoslavia in April 1941, Šakić, aged 19, joined the administration in Jasenovac. He became the camp's assistant commander the following year, and married Nada Luburić, the half-sister of concentration camp commander Vjekoslav "Maks" Luburić, in 1943. This marriage, as well as his fanatic support for Ustaše leader Ante Pavelić, led to Šakić'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.

[EX Q]: Question: How long did the battle where Roussel de Bailleul refused to fight last? Passage 1:Live in Atlantic City contains live performances of twenty-one songs along with a new song "God Made You Beautiful", written by Australian singer-songwriter Sia Furler. Several short excerpts of the performances found on the film are also featured in Life Is But a Dream itself. The film opens with Beyoncé appearing in front of a large screen with her silhouette being seen. As the music of "End of Time" starts, she performs a choreography with her female dancers and French duo Les Twins on stage further singing the song's lyrics. "Get Me Bodied" follows with a similarly choreographed performance and for the third song "Baby Boy", the singer dances with her background dancers in front of a holographic background performing a Dutty Wine dance at the end. "Crazy in Love" and "Diva" are featured as the fourth and fifth song, respectively. "Naughty Girl" is preceded by a video projection with a voice-over by Beyoncé talking about female sexuality. A snippet of Donna Summer's "Love to Love You Baby" is interpolated within it and the singer performs the song with her female dancers. She continues with "Party" for which a prominent Las Vegas showgirl theme is featured.
 Passage 2:He was present at the Battle of Manzikert in 1071, where he refused to join the fray; the battle proved to be a disastrous defeat for the Byzantines. Despite this treachery, he was kept in imperial service, where good generals were needed, and was sent into Asia Minor again with a force of 3,000 Franco-Norman heavy cavalry. There Roussel conquered some territory in Galatia and declared it an independent state in 1073, with himself as prince, following the example set by his fellow Normans in the Mezzogiorno. His capital was Ankara, now the capital of Turkey. He defeated the Caesar John Ducas and sacked Chrysopolis, near Constantinople. He even supported a usurper candidate, but by formally ceding lands that the Seljuk Turks had actually conquered, the emperor Michael VII persuaded the Seljuk warlord Tutush I to remove Roussel. However both Ducas and Roussel were defeated and captured by Turkish forces, fortunately for Roussel his wife was able to pay the ransom demanded by the Turks allowing Roussel to return to Amasea, where the population so loved him that he made himself undisputed governor. He was given up by the people through a ploy of Alexius Comnenus (1074), then a general, later an emperor. 
 Passage 3:The regiment was raised by the Honourable East India Company as the Madras Europeans from independent companies in 1742 – "European" indicating it was composed of white soldiers, not Indian sepoys. It saw action at the Siege of Arcot in autumn 1751 during the Second Carnatic War and went on to fight at the Battle of Plassey in June 1757, the Battle of Condore in December 1758 and the Battle of Wandiwash in January 1760 during the Seven Years' War. It also fought at the Siege of Pondicherry in September 1760 during the Third Carnatic War. It became the 1st Madras Europeans, on formation of the 2nd and 3rd Madras Europeans, in 1766. It went on to become the 1st Madras European Regiment in 1774. After that it took part in the Siege of Nundydroog in October 1791 and the Siege of Seringapatam in February 1792 during the Third Anglo-Mysore War.

[EX Q]: Question: How old was Louis de Branges when he proved the Bieberbach conjecture? Passage 1:Sherwood later began taking acting lessons and landed a guest role on the TV sitcom My Wife and Kids. In 2003, she was cast in the short lived series Platinum as the feisty Jade Rhames alongside Sticky Fingaz and Jason George. The show was written by Sophia Coppola and was about two brothers who ran a hip hop record label. it was canceled and only aired six episodes. During 2003, Sherwood guest starred on Boston Public, in which she played Dina Fallow. In 2005, she appeared in two films: as Tosha Cooper in Back in the Day, alongside Tatyana Ali, and as Patty in the horror film Venom, also starring Agnes Bruckner and Jonathan Jackson. Venom was harshly received by critics, with Entertainment Weekly dubbing it a "crappy horror movie". She guest starred on The Bernie Mac Show as Sherri in the episode Jack and Jacqueline.
 Passage 2:The Texans responded to the 2010 poor defensive showing by firing defensive coordinator Frank Bush, secondary coach David Gibbs, linebackers coach Johnny Holland, and assistant linebackers coach Robert Saleh. Kubiak, a ball boy for beloved former Houston Oilers head coach O.A. "Bum" Phillips in the 1970s, hired long-time friend, and Bum's son, Wade Phillips to take over as the Texans' new defensive coordinator on January 5, 2011. Phillips became available after being fired as head coach of the Dallas Cowboys halfway through the 2010 season. Phillips was allowed to bring in his own assistant coaches. The Texans signed two high-profile free agent defensive backs, Johnathan Joseph and Danieal Manning, and used their first five draft picks, including two in the second round of the 2011 NFL Draft, on more defensive players.
 Passage 3:Bieberbach wrote a habilitation thesis in 1911 about groups of Euclidean motions – identifying conditions under which the group must have a translational subgroup whose vectors span the Euclidean space – that helped solve Hilbert's 18th problem. He worked on complex analysis and its applications to other areas in mathematics. He is known for his work on dynamics in several complex variables, where he obtained results similar to Fatou's. In 1916 he formulated the Bieberbach conjecture, stating a necessary condition for a holomorphic function to map the open unit disc injectively into the complex plane in terms of the function's Taylor series. In 1984 Louis de Branges proved the conjecture (for this reason, the Bieberbach conjecture is sometimes called de Branges' theorem). There is also a on space groups. In 1928 Bieberbach wrote a book with Issai Schur titled Über die Minkowskische Reduktiontheorie der positiven quadratischen Formen.
