Part 2. Example
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: How old was the former commander of the 40th Regiment of Foot when MacDowall came to replace him? Passage 1:Becoming editor of La Lanterne in 1882, he founded two years later Le Matin. In December, 1882, he was chosen to represent the Gros-Caillou quarter in the municipal council of Paris, and was reelected in 1884. Dreyfus in this position showed a remarkable aptitude for finance. In October, 1885, he was elected deputy by the department of the Seine, and was reelected, for the Twelfth District, in 1889, in opposition to a Boulangist candidate. A radical, with wide schemes of reform, Dreyfus sat with the Extreme Left. He was appointed a member of the army commission, and also on that of espionage. He fought many duels, one with the Marquis de Morès, the anti-Semite. His publications include: Une Dictature (Le Mans, 1874); Giboyer à Saint-Pélagie (Paris, 1875); L'Evolution des Mondes et des Sociétés (Paris, 1888); Les Traités de Commerce (Tours, 1879); Le Tunnel du Simplon et les Intérêts Français (Paris, 1879); L'Angleterre, son Gouvernement, ses Institutions (Paris, 1881); La Guerre Nécessaire, Réponse d'un Français à M. de Bismarck (Paris, 1890). Dreyfus was also secretary and part founder of La Grande Encyclopédie. He was a member of the Légion d'honneur.
 Passage 2:France–United Kingdom relations are the relations between the governments of the French Republic and the United Kingdom of Great Britain and Northern Ireland (UK). The historical ties between France and the UK, and the countries preceding them, are long and complex, including conquest, wars, and alliances at various points in history. The Roman era saw both areas, except northern England and Scotland, conquered by Rome, whose fortifications exist in both countries to this day, and whose writing system introduced a common alphabet to both areas; however, the language barrier remained. The Norman conquest of England in 1066 decisively shaped English history, as well as the English language. In the medieval period, the countries were often bitter enemies, with both nations' monarchs claiming control over France. Some of the noteworthy conflicts include the Hundred Years' War and the French Revolutionary Wars which were French victories, and the Seven Years' War, Second Hundred Years’ War and Napoleonic Wars, from which Britain emerged victorious.
 Passage 3:MacDowall was appointed Lieutenant-Colonel of the 57th Regiment of Foot in 1791 and served in Flanders in 1793 and after serving as Commander-in-Chief in Ceylon from 1798 to 1804. In 1802, as a Major-General, he was appointed Colonel commandant of a Battalion of the 40th Regiment of Foot in place of Lord Hutchinson. He was appointed Commander-in-Chief of the Madras Army in 1807. He was made Colonel of the 41st Regiment of Foot in 1808. Following a period of dispute with the civil government of Madras over his exclusion from its council, and the affair of the arrest of Quartermaster-General John Munro, he resigned his commission in January 1809 and took ship for England on the East Indiaman Lady Jane Dundas. The ship was lost with all hands near the Cape of Good Hope in March 1809.
