Let me give you an 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.

. 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.

Question: Which network has aired Teletubbies the longest? Passage 1:On August 21, 2001 Virus participated in his first major CMLL tournament, the Torneo Gran Alternativa ("Great Alternative Tournament") where he was teamed up with Blue Panther. In the first round they defeated the team of Alan Stone and Mr. Niebla but lost to Olímpico and Sicodelico Jr., who would go on to win the entire tournament. After having been a Rudo (a Heel, or bad guy) his entire career Virus was turned Tecnico (Face or good guy) in 2002. In 2003 he took part in a series of matches between CMLL tecnicos, himself, Ricky Marvin and Volador, Jr., and a group called "the Havana Brothers" based out of southern California that consisted of Rocky Romero, Ricky Reyes and T.J. Perkins). The well received series of matches between the six led CMLL to create the CMLL World Super Lightweight Championship. Rocky Romero became the first champion but lost the title to Virus on November 14, 2003. Virus held the title for 392 days before losing it back to Rocky Romero. In 2005 Virus was turned Rudo once more and generally used to help young, high-flying tecnicos get more experience. Over the summer of 2006 Virus represented CMLL in All Japan Pro Wrestling's Junior Heavyweight League tournament. He ended up winning only one match, defeating MAZADA but lost to Katsuhiko Nakajima and Katsushi Takemura, failing to advance in the tournament. On October 2, 2007 Virus won CMLL's recurring Reyes del Aire ("Kings of the Air") tournament outlasting 11 other competitors in a torneo cibernetico, lastly eliminating Valiente to win the match.
