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: What years was Billy Hughes the prime minister? Passage 1:Billy Hughes was a former prime minister who had been successively a member of the Labor Party, the National Labor Party, and the Nationalist Party. By 1928, he was the de facto leader of a group of backbenchers hostile to the government of Stanley Bruce (who had replaced him as Nationalist leader in 1923). He and his supporters began to frequently cross the floor and vote against the government, particularly on the controversial subject of industrial relations. On 22 August 1929, Hughes and Edward Mann were expelled from the Nationalist Party for voting in favour of an unsuccessful censure motion against the government. Tensions finally came to a head on 10 September, when Hughes successfully moved an amendment to the government's flagship Maritime Industries Bill. Bruce took this to be a vote of no confidence, and called an election for 12 October. Labor under James Scullin won a landslide victory, while Hughes and two other ex-Nationalists were re-elected as independents.
 Passage 2:In 1993, Vintage Crop made a brief return to hurdling to finish sixth to Granville Again in the Champion Hurdle at Cheltenham Racecourse before being aimed at long distance races on the flat. He won a minor race at Leopardstown Racecourse and the Listed Curragh Cup as well as being placed in the Saval Beg Stakes and the Meld Stakes and finishing sixth in the Ascot Gold Cup. On 18 September, the gelding ran for the second time in the Irish St Leger and started at odds of 9/2 against a field which included Drum Taps and Snurge. Ridden by Mick Kinane, he took the lead approaching the final quarter mile and won by two and a half lengths from Assessor. Vintage Crop was then sent to Australia in an attempt to become the first foreign-trained horse to win the Melbourne Cup. Ridden again by Kinane, the Irish gelding produced a strong run in the straight to overtake Te Akau Nick in the closing stages and win going away by three lengths. The unplaced horses included Subzero, The Phantom and Drum Taps.
 Passage 3:The airline was established in 1993 by Mike Brady of Express Airlines I in Atlanta, Georgia. The airline started operations in August 1993. Its route structure in many ways mimiced an unrelated defunct predecessor named Chicago Air which also operated from Chicago Midway's airport less than a decade before. On June 1, 1999, Chicago Express became a wholly owned subsidiary of Amtran, later known as ATA Holdings and now Global Aero Logistics, and operated as ATA Connection, a regional code sharing affiliate of the now defunct ATA Airlines (formerly known as American Trans Air). Chicago Express' principal base of operations was Chicago Midway International Airport, where the company maintained its headquarters. For several months before its liquidation, the company also operated a hub in Indianapolis, part of ATA's failed plan for intrastate flights throughout Indiana. However, following ATA Holdings' decision to codeshare flights with Southwest Airlines, a decision was made to terminate Chicago Express effective March 28, 2005, in favor of a strictly mainline operation. CSC Investment Group, Inc., headed by CEO Edward S. Halley, purchased the airline in 2005 for $3.2 million.
