One 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.

Now, solve this: Question: What degree did Mikhail Sumarokov-Elston earn from St. Petersburg University? Passage 1:Mikhail Sumarokov-Elston was born on in 1893 to Count Nicholai Felixovich Sumarokov-Elston reserve Lieutenant of the Cavalry Regiment and Countess Sofia Mikhaylovna Koskul. He was the great-great-great-great-grandson of poet Alexander Sumarokov and the Great Great Grandson of Field Marshal Mikhail Kutuzov. He was the nephew of tennis player Count Pavel Sumarokov-Elston, who was his first coach and doubles partner, grandson of Count-General Felix Sumarokov-Elston, Governor of Kuban Oblast, and cousin of the infamous Prince Felix Yussupov, who later became known as one of the collaborators who conspired to kill Grigori Rasputin, cult leader and mentor of Empress consort of Russia Alexandra. Felix provided his own palace for the murder spot and also shot Rasputin once before murdering him with the help of his accomplices. Mikhail had a sister called Elena and a brother Nicholas. At the age of twelve he had a surgery on his right hand, which as a result was rendered unsuitable for tennis and he later switched to left-hand play. First he moved to Dresden and was trained by Kurt Bergmann and George K. Logie. In 1906 he entered the second-class tournament of the Bad Homburg Championships, where he defeated Jack Hillyard amongst many to claim his first title. With this he set a record of being the youngest winner ever at the time in the history of the tournament. In 1908 his father and brother died within two weeks of each other. He moved back to his homeland and graduated first at the Annenschule then at the Law Faculty of the St. Petersburg University.
