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: In what states did John Marshall serve in the American Revolution? Passage 1:Shovell's fleet of twenty-one ships left Gibraltar on 29 September, with serving as his own flagship, HMS Royal Anne as flagship of Vice-Admiral of the Blue Sir George Byng and as flagship of Rear-Admiral of the Blue Sir John Norris. The passage was marked by extremely bad weather and constant squalls and gales. As the fleet sailed out on the Atlantic, passing the Bay of Biscay on their way to England, the weather worsened and storms gradually pushed the ships off their planned course. Finally, on the night of 22 October 1707 Old Style, (2 November 1707 by the modern calendar), the squadron entered the mouth of the English Channel and Shovell's sailing masters believed they were on the last leg of their journey. The fleet was thought to be sailing safely west of Ushant, an island outpost off the coast of Brittany. However, because of a combination of the bad weather and the mariners' inability to accurately calculate their longitude, the fleet was off course and closing in on the Isles of Scilly instead. Before their mistake could be corrected, the fleet struck rocks and four ships were lost:
 Passage 2:After the 1775 Battles of Lexington and Concord, Thomas and John Marshall volunteered for service in the 3rd Virginia Regiment. In 1776, Marshall became a lieutenant in the Eleventh Virginia Regiment of the Continental Army. During the American Revolutionary War, he served in several battles, including the Battle of Brandywine, and endured the winter at Valley Forge. After he was furloughed in 1780, Marshall began attending the College of William and Mary. Marshall read law under the famous Chancellor George Wythe at the College of William and Mary, and he was admitted to the state bar in 1780. After briefly rejoining the Continental Army, Marshall won election to the Virginia House of Delegates in early 1782.
 Passage 3:She was born in New Orleans, Louisiana, and was graduated from Vassar College in 1949. In 1950, she married Tobin Armstrong and moved to Kenedy County, Texas. From 1966 to 1968, she was the vice chairman of the Texas Republican Party. From 1971 to 1973 she was Co-chairman of the Republican National Committee, and she was the keynote speaker at the 1972 Republican National Convention. (She was the first woman from either major party to keynote at a national convention). Nixon named her as Counselor to the President on 19 December 1972, which she held from January 19, 1973 to November 1974 under President Ford. During her tenure as Counselor, Armstrong founded the first Office of Women's Programs in the White House, predecessor to the current White House Council on Women and Girls. Fluent in Spanish, she was Nixon's liaison to Hispanic Americans and was a member of a Cabinet committee on opportunities for Spanish-speaking people. In 1973, a young Karl Rove, then on his way to becoming the chairman of the College Republicans, suggested in a memorandum to Armstrong that the Republican Party show nonpolitical films (such as John Wayne movies and Reefer Madness) at College Republican clubs as part of a strategy to raise support for the party among students and for fundraising.
