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.

Now, solve this instance: Question: How many teams did Dubai have? Passage 1:The maple leaf has been used as a Canadian emblem since the 18th century. It was first used as a national symbol in 1868 when it appeared on the coat of arms of both Ontario and Quebec. In 1867, Alexander Muir composed the patriotic song "The Maple Leaf Forever", which became an unofficial anthem in English-speaking Canada. The maple leaf was later added to the Canadian coat of arms in 1921. From 1876 until 1901, the leaf appeared on all Canadian coins and remained on the penny after 1901. The use of the maple leaf by the Royal Canadian Regiment as a regimental symbol extended back to 1860. During the First World War and Second World War, badges of the Canadian Forces were often based on a maple leaf design. The maple leaf would eventually adorn the tombstones of Canadian military graves.
 Passage 2:In 1983 Linda Ronstadt took a break from recording contemporary music in order to make an album of standards with conductor Nelson Riddle, and their collaboration, What's New went triple Platinum. Barbra Streisand's 1985 release The Broadway Album reached number one and went on to quadruple Platinum certification, so a renewed interest in what came to be known as traditional pop was evident. Mathis had not tried a studio album without current hits or new songs since the ill-fated Broadway project in 1965, so his choice to collaborate with Henry Mancini in 1986 for The Hollywood Musicals, which had a lineup of classics that were mostly from the 1940s, was quite a change of pace. And while he has done some albums of contemporary pop songs since then, the category in which he has received four Grammy nominations since 1992 has been Best Traditional Pop Vocal Album, and the industry has recognized his past work as well. Three of his recordings have been inducted into the Grammy Hall of Fame ("Chances Are" in 1998, "Misty" in 2002, and "It's Not for Me to Say" in 2008), and in 2003 he was given the Grammy Lifetime Achievement Award.
 Passage 3:He was selected as Sepahan's assistant coach in 2006 by Luka Bonačić. After Sepahan was unable to win the 2007–08 season and was ranked as runner up like AFC Champions League and winning Hazfi Cup in both 2006 and 2007, Bonačić was resigned as Sepahan's head coach and was appointed as Dubai based team, Al-Nasr Sports Club. He was selected Ghanbari as his first team assistant coach which was worked with him until his dismissal in February 2009. After he expired his contract with Al-Nasr, he became assistant manager of Sepahan for a second time under management of Amir Ghalenoei. He continue his career with Sepahan after Ghalenoie's resignation in 2011. Bonačić was appointed as Sepahan head coach for a second tensure and Ghanbari was one of his assistants. On 14 August 2011 and after Bonačić was sacked by club due to bad results, Ghanbari became caretaker manager of Sepahan. He was replaced with Zlatko Kranjčar after Sepahan was eliminated from Hazfi Cup. On 30 May 2012, he was named as Mansour Ebrahimzadeh's assistant coach in Naft Tehran. After Ebrahimzadeh signed as head coach of Rah Ahan, Ghanbari also signs a contract to become his assistant.
