In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
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: What was the highest rank reached by  the man who lead the mission to Japan in 1857? Passage 1:Mary was born the only child to David Turnbull (1900-1961), a native farm-owner in the Cheviot Hills, and Edna Mary Williamson (1901-1991), a schoolteacher from Laxey in the Isle of Man, on a farm not far from Wooler, Northumberland. In the 1920s Coventry grew to be the centre of UK motor industry, and her family moved to the thriving city when her father, who had been forced give up farming as a result of the Great Depression, found a job in motorcar engineering at the Rootes car factory. Throughout her childhood Mary led a happy but simple life despite having to live with different relatives during the Great Depression while her parents were both looking for work in Coventry, and being evacuated several times during World War II. She often described the experience of living through the Coventry Blitz and later, as a university student, the "doodlebugs" (V-1 flying bombs) in London.
 Passage 2:Dinko Šakić (8 September 1921 – 20 July 2008) was a Croatian fascist leader and war criminal who commanded the Jasenovac concentration camp in the Independent State of Croatia (NDH) from April to November 1944, during World War II. Born in the village of Studenci, near the town of Imotski in what was then the Kingdom of Serbs, Croats and Slovenes, he became a member of the fascist Ustaše at a young age. When the Axis powers occupied the Kingdom of Yugoslavia in April 1941, Šakić, aged 19, joined the administration in Jasenovac. He became the camp's assistant commander the following year, and married Nada Luburić, the half-sister of concentration camp commander Vjekoslav "Maks" Luburić, in 1943. This marriage, as well as his fanatic support for Ustaše leader Ante Pavelić, led to Šakić's appointment as commander of Jasenovac in April 1944. He was charged in the deaths of an estimated 2,000 people who died during his six months of command at the concentration camp.
 Passage 3:Pompe van Meerdervoort traveled to Japan in 1857 with the second Dutch military mission led by Lieutenant Willem Huyssen van Kattendijke. Since the beginning of the seventeenth century, the ruling Tokugawa shogunate of Japan pursued a policy of isolating the country from outside influences. Foreign trade was maintained only with the Dutch and the Chinese and was conducted exclusively at Nagasaki. However, by the early nineteenth century, this policy of isolation was increasingly under challenge. Following the Perry Expedition and with the increased threat to Japanese sovereignty posed by the European powers and their Black ships, the Japanese government turned towards the Dutch for technical and military assistance. The Nagasaki Naval Training Center was opened in 1855 with Dutch military advisors to teach the Japanese about steam warship technology. On arrival, he found that his predecessor Jan Karel van den Broek had been devoting much of his energies into production of a Japanese-Dutch/Dutch-Japanese dictionary, and acting as technical advisor on a wide range of engineering and technical questions, rather than concentrating on medicine or medical education. However, this provided Pompe van Meerdervoort with a foundation on which he was able to establish a school of western medicine on 12 November 1857. Initially, he had only twelve students and used the residence of Takashima Shūhan to lecture on biology, chemistry, human anatomy, physiology, and pathology. He performed the first recorded human autopsy in Japan, and his student base quickly expanded to over 133 students, including Kusumoto Ine, the daughter of Philipp Franz von Siebold. The Nagasaki Naval Training Center was closed in 1860 and its Dutch staff withdrawn, with the exception of Pompe van Meerdervoort.
