One 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.

Explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this: Question: Is Prague the capital of a country? Passage 1:The Locust Music releases (curated and designed by Dawson Prater) showcase the full range of his musical interests from minimalism, hillbilly country and garage rock. "C Tune" (Locust, 2002) documents a 1980 live improvisation with Catherine Christer Hennix on tamboura and Flynt on electric violin. "Raga Electric: Experimental Music 1963-1971" (Locust, 2002) is the seminal anthology of Flynt's most challenging avant-garde work that includes "Raga Electric" (1966) and "Free Alto" (1964). "Back Porch Hillbilly Blues - Volume 1" (Locust, 2003), with "Acoustic Hillbilly Jive" and "Blue Sky Highway and Tyme", and "Back Porch Hillbilly Blues Volume 2" (Locust) showcase a meeting of Henry Flynt's vision of rural roots music and American minimalism. "I Don't Wanna" (Locust Music, 2004) documents a garage-punk band, the Insurrections, that Flynt led in 1966 with Walter De Maria and Paul Breslin. "Purified by the Fire" (Locust, 2005), recorded in December 1981, repeats the format of "C Tune": Catherine Christer Hennix on tamboura and Flynt on electric violin. The 41-minute raga is dominated by the languid phrases of the violin that tests the border between melodic fragments and distorted tones. The "Indian" element is the background of hypnotic tamboura drones, but Flynt's improvisation at the violin betrays the influence of jazz music."Henry Flynt & Nova'Billy" (Locust, 2007) collects material recorded between 1974 and 1975 by his rock band Nova'Billy. "Dharma Warriors" (Locust, 2008) showcases another meeting between Catherine Christer Hennix & Flynt recorded in 1980 in Woodstock, New York.
 Passage 2:In the months following up to the September 11 attacks, officials at the Czech Interior Ministry asserted that Atta made a trip to Prague on April 8, 2001, to meet with an Iraqi intelligence agent named Ahmed Khalil Ibrahim Samir al-Ani. This piece of information was passed on to the FBI as "unevaluated raw intelligence". Intelligence officials have concluded that such a meeting did not occur. A Pakistani businessman named Mohammed Atta had come to Prague from Saudi Arabia on May 31, 2000, with this second Atta possibly contributing to confusion. The Egyptian Mohamed Atta arrived at the Florenc bus terminal in Prague, from Germany, on June 2, 2000. He left Prague the next day, flying on Czech Airlines to Newark, New Jersey, U.S. In the Czech Republic, some intelligence officials say the source of the purported meeting was an Arab informant who approached the Czech intelligence service with his sighting of Atta only after Atta's photograph had appeared in newspapers all over the world. United States and Czech intelligence officials have since concluded that the person seen with Ani was mistakenly identified as Atta, and the consensus of investigators has concluded that Atta never attended a meeting in Prague.
 Passage 3:UNICS has gone a long way towards helping Russian basketball since the club was established in 1991. Between 1994 and 1997, UNICS secured a berth in Russia's first division, and then made a smashing debut, establishing itself among the top five teams in the country. UNICS had already played in European competitions in 1997, but the new millennium happened to be a turning point for the club. The team placed second to CSKA in the Russian Basketball Super League in 2001 and 2002, the year in which it also reached the Saporta Cup semifinals, losing against the Greek club Maroussi in the semifinals. UNICS' first title was the Russian Cup in March 2003, with an electrifying 81–82 overtime victory over CSKA. UNICS' fans did not have to wait long to see their team win a European title, too. Kazan hosted the FIBA Europe League final four, which was eventually named the FIBA EuroChallenge, in April 2004, and UNICS made sure of its opportunity. UNICS signed Saulius Štombergas, Eurelijus Žukauskas, and Chris Anstey, and then won its regular season group, and advanced to the final four, which was held on its own floor, and where the club was crowned the FIBA Europe League champions. The MVP of the tournament's final four, Martin Müürsepp, scored 22 points, in an 87–63 win over Maroussi, in the title game. By the 2005–06 season, UNICS went one level up, and made its ULEB Cup (later named EuroCup) debut, where they tied the best regular season record in the competition's history. However, things turned south quickly, as UNICS lost at home against Roma, for the only time all season, in the tournament's eighth finals’ second leg, and crashed out earlier than expected. UNICS got stronger for the next season, keeping the core group of the previous season's side, while adding Darjuš Lavrinovič to reunite with his twin brother Kšyštof Lavrinovič, in a twin-towers set full of talent. The team made it to the ULEB Cup semifinals, before losing to the eventual league champs Real Madrid. It also returned to the Russian League finals, losing against perennial champion CSKA.
