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.

Q: Question: Who is the current leader of the clan that ruled the Choshu domain? Passage 1:The area around present-day Atsugi city has been inhabited for thousands of years. Archaeologists have found ceramic shards from the Jōmon period at numerous locations in the area. By the Kamakura period, this area part of the Mōri shōen, part of the holdings of Ōe no Hiromoto. His descendants, the Mōri clan later ruled Chōshū domain. During the Kamakura period, the area was also known for its foundry industry for the production of bells for Buddhist temples. The area came under the control of the Ashikaga clan in the early Muromachi period and was later part of the territories of the Later Hōjō clan from Odawara. With the start of the Edo period, the area was tenryō territory controlled directly by the Tokugawa shogunate, but administered through various hatamoto, as well as exclaves under the control of Odawara Domain, Sakura Domain, Mutsuura Domain, Ogino-Yamanaka Domain and Karasuyama Domain. After the Meiji Restoration, the area was consolidated into Aikō District of Kanagawa Prefecture by 1876. Atsugi town was created on April 1, 1889 through merger of several small hamlets. Atsugi was elevated to city status on February 1, 1955 through merger with neighboring Mutsuai Village, Koaiyu Village, Tamagawa Village and Minamimori Village. The city expanded on July 8, 1958 through merger with neighboring Echi Village, and with Aikawa Village from Naka District. On September 30, 1956, Ogino Village joined with Atsugi. In April 2000, Atsugi exceeded 200,000 in population and was proclaimed a special city with increased autonomy from the central government.
