Question: What year did the war end during which Šakić commanded the Jasenovac concentration camp? 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.
