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 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: Which drivers finished ahead of Fabio Leimer in the 2011 Asia series? Passage 1:For 2011, Leimer moved to the Rapax team alongside Julián Leal. He finished fifth overall in the Asia series, and then proceeded to take his second category win in the main series. As was the case the previous year, the victory came in the sprint race at the Catalunya circuit, and he again set the fastest lap in the process, although on this occasion he owed his reverse-grid pole position to Romain Grosjean's disqualification from the feature race. Another haul of points at Monza saw him improve to 14th position in the championship standings. He also won the feature race of the non-championship event held at the Yas Marina Circuit. Leimer switched to the Racing Engineering team for 2012, where he partnered Nathanaël Berthon. Despite failing to win a race during the season, his improved consistency, consisting of six podium finishes, saw him improve to seventh place in the drivers' championship. Leimer took the GP2 driver's championship title in 2013, with seven podium finishes and three wins.
 Passage 2:Greenberg had expressed the wish that he should be cremated and his remains buried, without any religious ceremony, near Mount Scopus in Palestine. The casket containing his ashes arrived in Haifa in November 1931, but the Orthodox rabbinate in Jerusalem insisted that since Jewish law prohibits cremation, it could not be buried in consecrated ground. Letters flew back and forth between London and Palestine as his son Ivan tried to resolve the impasse. In January 1932, Joe Linton, one of Weizmann's aides, suggested burying the casket in Herbert Bentwich's private garden near Mount Scopus. This would have been a nice irony since the two men had loathed one another. In any event, this solution was over-ruled by the rabbinate. By May 1932, the casket was still in the customs office in Haifa, and officials threatened to throw it out if something was not done about it. Eventually, through the combined efforts of Moshe Sharett (later Foreign Minister and Prime Minister of Israel) and Chaim Arlosoroff, both high-ranking officials in the Jewish Agency, a resting place for Greenberg's remains was found at Kibbutz Degania by the shore of the Sea of Galilee.
 Passage 3:In the United States it is the State Tree of Maine (as of 1945) and Michigan (as of 1955). Its "pine cone and tassel" is also the State Flower of Maine. Sprigs of eastern white pine were worn as badges as a symbol of Vermont identity during the Vermont Republic and are depicted in a stained glass window in the Vermont State House, on the Flag of Vermont, and on the naval ensign of the Commonwealth of Massachusetts and the state of Maine. The 1901 Maine Flag prominently featured the tree during its brief tenure as Maine's state flag. The Maine State Guard also use the tree in their uniform badges.
