Example: 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.

 Passage 2:Other examples of mostly locally generated historical markers in the United States include the plaque outside the Alaska Governor's Mansion made by the Alaska Centennial Commission's historical markers program, the historical markers of State Historic Marker Council in Florida, the markers placed by various agencies in Georgia (of which one source mentions 3,292 different historical markers), in Indiana, where it is illegal to create a historical marker in the "state format" without first getting official approval from that state's historical bureau, historical markers in Kansas erected by the Kansas Historical Society and the Kansas Department of Transportation, the Roadside Historic Marker Program in Maryland administered by the Maryland Historical Trust, the State Historic Marker Program of New York (begun in 1926 to commemorate the Sequicentennial of the American Revolution), the historic markers placed as recently as 2008 in Sussex County, New Jersey, the New Mexico historical markers printed in white letters on a brown background by the New Mexico Department of Transportation, the historical markers of North Carolina (the Historical Publications Section of the state Office of Archives and History publishes a Guide to North Carolina Highway Historical Markers), the more than 1200 historical markers of Ohio (all of which are now made in a Marietta, Ohio workshop), and over 550 official state markers in Wisconsin.
 Passage 3:In Brisbane they soon became known for their unique shows, experimentation and friendliness. After some initial hardships, McSweeney soon found like-minded musicians in Josh Engelking (percussion), Bo Whitton (bass guitar), Ellen Stancombe (violin) and Wayne Jennings (cello). The newly formed lineup soon released the "Rain" single. Based on the single and performances, McSweeney soon began to feature heavily in local media, becoming known for his revolutionary views on music, eccentric interviews/performances and the influence of his colour synesthesia on his music and art. In 2006 the band conducted two extensive national tours, including sets at the coveted Livid and Big Day Out festivals. Following this success, a live performance was recorded with Brisbane community radio station 4ZZZ FM and was released in 2004 as the album The Virgin Mary Australian Tour Acoustic/Strings Album, which received yet more positive feedback. They also headlined the 2004 Valley Fiesta, and played support for Australian singer–songwriter Missy Higgins. 2005 saw the band conduct a two-week tour of China, and release the Walls EP with Modern Music/Sony BMG to critical acclaim. The EP received high rotation play on the national Triple J radio station and generated plenty of new fans. The title track, "Walls", entered the stations "Net 50" chart at #3 and charted for fifteen weeks. Sometime around this release bass player Bo Whitton left the band and was replaced by Amanda Holmes.
