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.

Problem: Question: In what city is the university where Riza studied located? Passage 1:Don Bartlett played lead for Kevin Martin beginning in 1991. It was in 1991 that the team won the Brier that year. The team would win the 1997 Brier. Internationally, Bartlett has been to two World Curling Championships and two Winter Olympics. At the 1991 Worlds, Martin, Walchuk, third Kevin Park and second Dan Petryk won a silver medal. At the 1992 Winter Olympics (demonstration), the team finished fourth place. In 1997, the team now consisting of Don Walchuk at third and Rudy Ramcharan at second placed fourth. At the 2002 Winter Olympics now with Carter Rycroft at second, the team won a silver medal. With Martin, Bartlett has been to seven Briers and has won two Canada Cups. Before Martin, Barlett played with Pat Ryan. He went to the 1985 Brier as his alternate player.
 Passage 2:During the Middle Ages of Indian history, many faiths and sects sprang up in religious and social spheres of Hindu society. Their practitioners slowly migrated away from the teachings of the Vedas attaching greater significance to their founders and their preachings. From then onwards polytheism commenced. Great differences developed among the different sects and divided and weakened Hindu society. The caste system based on birth became strong and gave rise to further fragmentation. Like with any aging society without reforms, the customs gave way to superstition and ignorance wherein practice superseded reason and the spread of blind faith threatened degradation of "Hindu" society. The word Hindu is an improper word or misnomer- the correct word is Vedantic or Sanathana Dharma, a religion based upon the Vedas. The word Hindu does not appear any where in the Vedic texts or even the Bhagavad Gita. The word Hindu is a Persian word, used by the Muslims and the renaming of the Vedantic religion to "Hindu" demonstrates the level of weakening to the Vedantic faith. "Hinduism" needs reforms.
 Passage 3:After her education from private teachers in Istanbul, she traveled to Paris, France in 1898 to meet her elder brother Ahmet Rıza, who was a member of the Young Turks movement. She studied in Sorbonne University, and was affiliated to the Committee of Union and Progress (CUP). She was the only female member of the committee. In Paris, she wrote in two newspapers published by CUP in Paris namely Mechveret Supplément Français in French and Şura'i Himmet in Turkish. In 1908, she returned to İstanbul, where she wrote in two newspapers; Hanımlara Mahsus Gazete ("Newspaper for Women") and Kadınlar Dünyası ("Ladies' World"). She also became the secretary general of Turkish Red Crescent between 1908–1913. During the last years of the Ottoman Empire, she worked hard to transform the Adile Sultan Palace, a royal palace in İstanbul, to a girls' school. With the help of her brother, she succeeded and the palace was used as Kandilli High School for Girls up to 1986, when it was partially burned down.
