Example input: 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.

Q: Question: How much time passed between the start of the First Carlist War and the end of the last war after Bilbao suffered a third seige? Passage 1:For the 2008 Isle of Man TT Races, following the deaths of a race competitor and two spectators at the 26th Milestone during the 2007 Senior TT a number of changes occurred in spectator safety and road widening occurred at Braddan Bridge and a new link road and mini-roundabout at Governor's Bridge. The race organisation changed with the Manx Motor Cycle Club (MMCC) replaced by ACU Events Ltd a subsidiary of the Auto-Cycle Union (ACU). A contract for the official course vehicles was awarded to Audi in a 3-year deal to celebrate the win by the pre-war Audi satellite company DKW by Ewald Kluge in the 1938 Isle of Man TT Races. A further contract was awarded to Yamaha UK to provide motor-cycles and support for the TT Travelling Marshalls. The Isle of Man TT competitor Martin Finnegan was killed while racing at the Tandragee 100 Races on 3 May 2008 and this was followed by the former Isle of Man TT and Manx Grand Prix winner Robert Dunlop who died in an accident on 16 May 2008 at Mather's Cross during practice for the 2008 North West 200 Races.
 Passage 2:Jowett was born in Peckham, Kent, and grew up in Camberwell, the third of nine children. His father was a furrier originally from a Yorkshire family that, for three generations, had been supporters of the Evangelical movement in the Church of England, and an author of a metrical translation of the Old Testament Psalms. His mother was a Langhorne, related to John Langhorne, the poet and translator of Plutarch. At twelve, Jowett was placed on the foundation of St Paul's School (then in St Paul's Churchyard) where he soon gained a reputation as a precocious classical scholar. Aged eighteen he was awarded an open scholarship to Balliol College, Oxford, where he remained for the rest of his life. He went up in 1836, and was quickly recognized as one of the leading Oxford dons of his generation, made a Fellow while still an undergraduate in 1838; he graduated with first-class honours in 1839. This was at the height of the Oxford Tractarian movement: through the friendship of W. G. Ward he was drawn for a time in the direction of High Anglicanism; but a stronger and more lasting influence was that of the Arnold school, represented by A. P. Stanley. The controversy caused Jowett to withdraw from High Table at college to lodgings in Broad Street.
 Passage 3:The Basque Country was one of the main sites of battles during the First Carlist War, a civil war between supporters of the Spanish regent Maria Christina, known as liberals, and those of the late king's brother Carlos of Borbón, known as Carlists. The Carlists were particularly focused on capturing Bilbao, a liberal and economic bastion in northern Spain. The Carlist general Tomás de Zumalacárregui tried to take the city during the Siege of Bilbao of 1835, but he was wounded during a battle near Begoña and died some time after in the town of Zegama. The next year, the city resisted a second siege during which the liberal general Baldomero Espartero defeated the Carlists in the Battle of Luchana. The city was untouched by the Second Carlist War, which took place mostly in Catalonia, but was again an important scenario during the Third Carlist War; in April 1874 the city suffered a third siege which lasted two months.
