Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Now, solve this instance: Question: The was the officer in charge of the United Nations Command during the Battle of Chongju? Passage 1:Jackson was a member of the council of IPPA, a forerunner of Pact, the body which established terms for trade between independent producers and the BBC and other broadcasters. PJP was eventually taken over by Noel Gay Television, a company chaired by the British entertainment executive, Bill Cotton. Jackson served as the Managing Director and the company produced Red Dwarf, the long-running and internationally successful comedy series, the pilot episode of Bottom (Rik Mayall and Adrian Edmonson) and, working with LWT, the hugely influential Channel Four variety show, Saturday Live. Saturday Live featured such comedy stars as Lenny Henry, Pamela Stephenson, Michael Barrymore, Peter Cook and Barry Humphries and brought to prominence talents such as Ben Elton (as a performer), Fry and Laurie, Harry Enfield and Julian Clary. The company also held the contract to provide all entertainment programming for the short lived UK satellite service, British Satellite Broadcasting and produced shows featuring then unknown names such as Armando Ianucci, Steve Coogan, Lee Evans and Jack Dee, as well as The Happening, a precursor to the long-running BBC show Later... with Jools Holland. In 1988 Jackson also co-produced the Oscar-winning short film, The Appointments of Dennis Jennings, starring Steven Wright and Rowan Atkinson.
 Passage 2:The monks initially won the support of Vitalian, an East Roman general who was the magister militum of Thrace and the leader of a powerful pro-Chalcedonian rebellion against Emperor Anastasius I, who was a convinced Monophysite. Vitalian was a native of Scythia Minor and one of the Scythian monks was a relative of his. The rebellion started in 512, when a nearly identical formula to that of the Scythian monks, added to the Trisagion in the liturgy of Hagia Sophia, was removed by Emperor Anastasius II. The rebellion continued until 515, when Vitalian was defeated and forced to go into hiding. By the reign of Anastasius' successor, Justin I, orthodoxy extended even to the army: soldiers were ordered to subscribe to the creed of Chalcedon or be deprived of their rations. At the beginning of the year 519, a delegation of Scythian monks traveled to Constantinople under the leadership of John Maxentius to bring their case before Emperor Justin I, proposing a new solution by arguing in favor of their formula. They were fiercely opposed by legates from Rome and by the Sleepless Monks (so-called for their around-the-clock prayer in eight-hour shifts) ironically, in trying to combat the Eutychian tendencies of the Scythian monks, the Sleepless Monks themselves shifted into Nestorianism, and were excommunicated by Pope John II for this). Faced with this opposition, the Scythian monks' view was that although the Chalcedonian definition (strongly supported by Rome) was indeed an orthodox expression of the faith, it was susceptible to a Nestorian misinterpretation which would in effect split Christ into two persons despite the verbal acknowledgment that Christ has only one person. The Scythian monks' proposal was not well received, mainly because of the timing: the monks arrived in Constantinople just as the emperor Justin I was negotiating an end to the Acacian schism. This split between Rome and Constantinople originated in 484 when Pope Felix III excommunicated Acacius, the Patriarch of Constantinople, for attempting to evade the council of Chalcedon in his attempt to bring the Monophysites back under control. Acacius had advised Emperor Zeno to issue a statement, the Henotikon (the "act of union"; 482), which was an attempt to reconcile the differences between the supporters of Orthodoxy and of Monophysitism. But the Henotikon failed to insist upon Chalcedon as the standard of orthodoxy, and the Council of Chalcedon, because of its endorsement of the Tome of Pope Leo I, had become a mark of the prestige of the Roman See. Acacius's apparent attempt to ignore Chalcedon was seen as an insult against Rome's claim to be the gold standard of orthodoxy. By the time the monks arrived in Constantinople, the political landscape changed and Emperor Justin's policies were directed more to the west than to the east where the Monophysites were dominant. This policy led him, in 519, to accede to Rome's demand that Chalcedon be the official christological confession of the empire. He received the emissaries from Rome in triumphal procession, and Patriarch John of Constantinople signed documents ending the thirty-five-year-old schism. Thus, when the Scythian monks arrived on the scene urging that the resolutions of Chalcedon needed to be supplemented with their Theopaschite formula, no one was willing to listen. The Scythian monks' views were interpreted as an attack on the Council of Chalcedon and thus a threat to the newly established reunion between Rome and Constantinople. A bishop from North Africa named Possessor, who was in Constantinople at the same time as the Scythian monks, also opposed their christological position by citing Faustus of Riez, whom the Scythian monks accused of the Pelagian heresy.
 Passage 3:The Battle of Chongju (29–30 October 1950) took place during the United Nations Command (UN) offensive towards the Yalu River, which followed the North Korean invasion of South Korea at the start of the Korean War. The battle was fought between Australian forces from 3rd Battalion, Royal Australian Regiment (3 RAR) and the 17th Tank Brigade of the Korean People's Army (KPA) for control of Chongju, North Korea and the surrounding area. After detecting a strong KPA armoured force equipped with T-34 tanks and SU-76 self-propelled guns on a thickly wooded ridgeline astride the line of advance, the Australians launched a series of company attacks with American M4 Sherman tanks and aircraft in support. Despite heavy resistance the KPA were forced to withdraw and the Australians captured their objectives after three hours of fighting.
