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.

. 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.

New input: Question:  What age was Kensuke Kitawhen Asian Kung-Fu Generation was first formed? Passage 1:Asian Kung-Fu Generation was first formed in 1996 when Masafumi Gotoh, Kensuke Kita, and Takahiro Yamada met while attending a music club at Kanto Gakuin University, a private university in Yokohama, Japan. After realizing that they all shared similar musical tastes, the three decided to start their own band. Masafumi Gotoh became the lead vocalist and played rhythm guitar, Kensuke Kita played lead guitar and sang backup and Takahiro Yamada played bass. Drummer Kiyoshi Ijichi joined them later on after parting with another college band he was in. The four then began providing performances at their university as well as throughout the local Yokohama area. After graduating from college, following years of playing in several small venues and having collaborated with fellow Japanese rock musician Caramelman, AKFG released their first indie EP in 2000. The six-track EP contained original lyrics written and sung almost entirely in English. The four spent the remainder of the year playing in clubs and hosting independent events.
 Passage 2:As part of its promotion, One Direction performed the song on televised programmes and during their worldwide Take Me Home Tour (2013). One Direction performed the track on The Today Show at the Rockefeller Center on 13 November 2012, to a record crowd estimated at 15,000. "Kiss You" was included in the set list of the group's 3 December 2012 sold-out show at New York City's Madison Square Garden. One Direction delivered a performance of "Kiss You", in front of a video game-themed set, on the final of the ninth series of The X Factor UK on 10 December 2012.
