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: In which country did Hue attend college? Passage 1:There is no official state religion in the Thai constitution, which guarantees religious freedom for all Thai citizens, though the king is required by law to be a Theravada Buddhist. The main religion practised in Thailand is Buddhism, but there is a strong undercurrent of Hinduism with a class of brahmins having sacerdotal functions. The large Thai Chinese population also practises Chinese folk religions, including Taoism. The Chinese religious movement Yiguandao (Thai: Anuttharatham) spread to Thailand in the 1970s and it has grown so much in recent decades to come into conflict with Buddhism; in 2009, it was reported that each year 200,000 Thais convert to the religion. Many other people, especially among the Isan ethnic group, practise Tai folk religions. A significant Muslim population, mostly constituted by Thai Malays, is present especially in the southern regions.
 Passage 2:Robert Hues (1553 – 24 May 1632) was an English mathematician and geographer. He attended St. Mary Hall at Oxford, and graduated in 1578. Hues became interested in geography and mathematics, and studied navigation at a school set up by Walter Raleigh. During a trip to Newfoundland, he made observations which caused him to doubt the accepted published values for variations of the compass. Between 1586 and 1588, Hues travelled with Thomas Cavendish on a circumnavigation of the globe, performing astronomical observations and taking the latitudes of places they visited. Beginning in August 1591, Hues and Cavendish again set out on another circumnavigation of the globe. During the voyage, Hues made astronomical observations in the South Atlantic, and continued his observations of the variation of the compass at various latitudes and at the Equator. Cavendish died on the journey in 1592, and Hues returned to England the following year.
 Passage 3:From May, 1941, it was transferred to an occupation force in Croatia. The battles with Yugoslav Partisans of increasing intensity were fought in November–December 1941 at Štirovača forest, Divoselo (Croatia), and Žuta Lokva, resulting ultimately in the Battle of the Neretva. It was fought initially at Gospić, Otočac and Bihać. The Yugoslav Partisans has launched a major assault on Korenica and Udbina from 2 January until 15 January 1942. These attacks were fended off by division Re, and in February–March, 1942, it participated in the mopping-up operation in the same area. The culmination of Battle of the Neretva for division Re was the Operation K, between 23 – 28 March 1942, carried out over six days by the Italian V Corps. The objective was to break through to and relieve the surrounded garrisons in Titova Korenica, Udbina and Donji Lapac the operation was successful and the division suffered only light casualties. In April, 1942, the Yugoslav Partisans has launched an assault on Mogorić and Bihać. Pressure was such what he garrison of Bihać had to be evacuated in June, 1942. All lost positions were recovered by the end of June, 1942, after fierce fighting.
