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: Did the coach of the Chargers from 1992 to 1996 coach any other professional teams? Passage 1:Suffocation was formed in 1988 on Long Island, New York, by vocalist Frank Mullen, guitarists Guy Marchais and Todd German, bassist Josh Barohn, and an unknown drummer. By 1990, the band had hired guitarists Terrance Hobbs and Doug Cerrito along with drummer Mike Smith, who were members of a local band called Mortuary, which had already disbanded. The quintet was mainly influenced by fellow American death metal bands as well as the British band Napalm Death and Brazilian Sepultura. Smith commented on meeting Hobbs for the first time: "That's where I first noticed, 'Wow, theres another black guy playing this kind of stuff'". The band's first EP, Human Waste, was released through Relapse Records in 1991. The full-length debut album, Effigy of the Forgotten, recorded by producer Scott Burns at Tampa's Morrisound Studios and released by Roadrunner Records the same year. In July 1991, Barohn was replaced by Chris Richards, as the album became substantially influential in extreme metal music.
 Passage 2:WEVD (originally broadcasting at 1220 kHz AM, later on 1300 kHz, for many years on 1330 kHz and finally on 1050 kHz), was an American brokered programming radio station with some news-talk launched in August 1927 by the Socialist Party of America. Making use of the initials of recently deceased party leader Eugene Victor Debs in its call sign, the station operated from Woodhaven in the New York City borough of Queens. The station was purchased with a $250,000 radio fund raised by the Socialist Party in its largest fundraising effort of the 1920s and was intended as spreading progressive ideas to a mass audience. A number of national trade unions and other institutions aided the Socialists in obtaining the station.
 Passage 3:Bobby Ross coached the Chargers from 1992 to 1996, and is the only coach to win awards while coaching the Chargers. In 1992, Ross won the Pro Football Weekly NFL Coach of the Year, the Maxwell Football Club NFL Coach of the Year and the UPI NFL Coach of the Year. The Pro Football Weekly NFL Coach of the Year is presented annually by various news and sports organizations to the National Football League (NFL) head coach who has done the most outstanding job of working with the talent he has at his disposal. The Maxwell Football Club NFL Coach of the Year was created in 1989 and is originally titled the Earle "Greasy" Neale Award for Professional Coach of the Year. The United Press International (UPI) NFL Coach of the Year award was first presented in 1955. Before the AFL-NFL merger, an award was also given to the most outstanding coach from the AFL. When the leagues merged in 1970, separate awards were given to the best coaches from the AFC and NFC conferences. The UPI discontinued the awards after 1996.
