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.

 Passage 3:About this time, some Dzungars informed the Kangxi Emperor that the 5th Dalai Lama had long since died. He sent envoys to Lhasa to inquire. This prompted Sangye Gyatso to make Tsangyang Gyatso the 6th Dalai Lama public. He was enthroned in 1697. Tsangyang Gyatso enjoyed a lifestyle that included drinking, the company of women, and writing love songs. In 1702, he refused to take the vows of a Buddhist monk. The regent, under pressure from the Emperor and Lhazang Khan of the Khoshut, resigned in 1703. In 1705, Lhazang Khan used the sixth Dalai Lama's escapades as excuse to take control of Lhasa. The regent Sanggye Gyatso, who had allied himself with the Dzungar Khanate, was murdered, and the Dalai Lama was sent to Beijing. He died on the way, near Kokonor, ostensibly from illness but leaving lingering suspicions of foul play. Lhazang Khan appointed a new Dalai Lama who, however, was not accepted by the Gelugpa school. Kelzang Gyatso was discovered near Kokonor and became a rival candidate. Three Gelug abbots of the Lhasa area appealed to the Dzungar Khanate, which invaded Tibet in 1717, deposed Lhazang Khan's pretender to the position of Dalai Lama, and killed Lhazang Khan and his entire family. The Dzungars proceeded to loot, rape and kill throughout Lhasa and its environs. They also destroyed a small force in the Battle of the Salween River which the Emperor had sent to clear traditional trade routes.
