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.

Part 3. Exercise
Question: When was the predominant religion of Utah citizens founded? Passage 1:Utah – state in the Western United States. It became the 45th state admitted to the Union on January 4, 1896. Utah is the 13th-largest, the 34th-most populous, and the 10th-least-densely populated of the 50 United States. Approximately 80% of Utah's 2,817,222 people live along the Wasatch Front, centering on Salt Lake City, leaving vast expanses of the state nearly uninhabited and making the population the sixth most urbanized in the U.S. Utah is the most religiously homogeneous state in the Union. Approximately 63% of Utahns are reported to be members of The Church of Jesus Christ of Latter-day Saints or LDS (Mormons), which greatly influences Utah culture and daily life. The world headquarters of The Church of Jesus Christ of Latter-day Saints (LDS Church) is located in Utah's state capital.
 Passage 2:Several German socialists of this period also exhibited anarchist tendencies. The young Wilhelm Weitling, influenced by both Proudhon and Louis Auguste Blanqui, once wrote that "a perfect society has no government, but only an administration, no laws, but only obligations, no punishment, but means of correction." Moses Hess was also an anarchist until around 1844, disseminating Proudhon's theories in Germany, but would go on to write the anti-anarchist pamphlet Die letzte Philosophie. Karl Grün, well known for his role in the disputes between Marx and Proudhon, held a view Nettlau would liken to communist anarchism while still living in Cologne and then left for Paris, where he became a disciple of Proudhon. Wilhelm Marr, born in Hamburg but primarily active in the Young Germany clubs in Switzerland, edited several antiauthoritarian periodicals. In his book on anarchism Anarchie oder Autorität, he comes to the conclusion that liberty is found only in anarchy.
 Passage 3:The current Constitution of the Republic of China was adopted by the National Assembly in 1947, when the Nationalist Government was based in Nanjing. Since 1945, China was engulfed in a civil war that pitted the Nationalist Government against the Communist Party of China (CPC). In March 1948, the first National Assembly met in Nanjing, and after some deliberation, decided to invoke Article 174 of the Constitution to amend the Constitution". On 10 May 1948, the Assembly adopted the first set of Temporary Provisions that was set to expire after three years. In 1949, the Communists expelled the Nationalist Government from mainland China, and Chiang's government set up base in Taipei, Taiwan. In 1954, the National Assembly indefinitely renewed the Temporary Provisions in view of the Kuomintang's plans to recapture the mainland. The Temporary Provisions from then on were amended in accordance with the needs of the President of the Republic of China, Chiang Kai-shek, or his son Chiang Ching Kuo. In 1966, the Temporary Provisions were revised to allow for supplementary elections to the National Assembly from the Taiwan Area. In 1971, the ROC was expelled from the United Nations and replaced with representatives from the People's Republic of China; the Temporary Provisions were amended again the same year.
