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.

New input case for you: Question: In what year was the railway company that was authorized to build two extensions in 1873 founded? Passage 1:In 1873, the Hoylake and Birkenhead Railway was authorised to construct two extensions to its lines. One was a short connecting section near to Birkenhead docks, and the other was the extension from Hoylake to West Kirby. The station and the extension were opened on 1 April 1878 as the terminus of the Wirral Railway's route from Birkenhead Park station. The station's original signal box was built in 1886, to a London and North Western Railway (LNWR) design. This signal box was removed and replaced in 1932. After the opening of the Mersey Railway Tunnel in 1886, carriages were operated through Birkenhead Park, every half-hour, all the way to James Street station in Liverpool. As traffic increased, the line into West Kirby was doubled, from a single track, in 1896. After a board meeting on 28 October 1895, it was decided to extend the line from Hooton, into West Kirby. The station was relocated on the western side of the original station, with an enlarged island platform and rebuilt, in 1898-9, in red brick, with a turreted clock tower and mock Tudor frontage. A further platform was constructed for the Hooton line, on the eastern side of the original station. The site of the original station was used for goods sidings. In the present day, this is the site of The Concourse, a community building operated by Wirral Metropolitan Borough Council.
 Passage 2:Meléndez began his wrestling career in 1951 at age 18. During a lengthy tenure in his native Puerto Rico, he went under various monikers and learned the ropes with the likes of Pedro Morales and Carlos Colón Sr.. Meléndez made his United States debut at Sunnyside Garden in Long Island, New York in 1963. Primarily using the name Gypsy Joe by this point, he mainly worked for Nick Gulas and later Jerry Jarrett in the Southeastern region, particularly Mid-Southern Wrestling. During his Gulas run, he was often teamed with heels like Tojo Yamamoto, with whom he formed the No Pain Train, and The Cuban Assassin. He also joined forces with Frank Martinez to be collectively known as the Blue Infernos. The masked duo would attain tag team championships on numerous occasions. By the 1970s, Gypsy Joe was a local star of Chattanooga, Tennessee, regularly performing at Soldiers and Sailors Memorial Auditorium on Saturdays and appearing on local WDEF-TV. His career wasn't limited to the South, however, winning championships around the country as well as in Canada’s Stampede Wrestling.
 Passage 3:Coming off their win over the Steelers the Jets played an interconference duel with the Bears. In the first quarter the Jets trailed early as kicker Robbie Gould got a 37-yard field goal, followed by Matt Forte getting a 22-yard TD run. The Jets pulled ahead with RB Shonn Greene getting a 3-yard TD run, followed by CB Dwight Lowery returning an interception 20 yards for a touchdown, followed by RB LaDainian Tomlinson getting a 3-yard TD run letting the Jets lead 21–10. The lead was narrowed as QB Jay Cutler scrambled 2 yards for a touchdown, but was soon extended as kicker Nick Folk made a 26-yard field goal. They trailed again with Cutler completing a 40 and a 25-yard TD pass to wide receivers Devin Hester and Johnny Knox respectively, but soon were able to tie the game with QB Mark Sanchez throwing a 23-yard TD pass to WR Santonio Holmes. The Bears escaped the tie with Cutler finding Knox again on a 26-yard TD pass. The Jets tried to come back, but only came away with a 34-yard field goal from Folk. When the Jets got the ball back, Sanchez threw a pass intended for Holmes, only to be intercepted by safety Chris Harris with 0:58 to go.
