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.
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.

Explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this: Question: How many other men had won the 10K before Kifle won in Spain in 2002? Passage 1:In his book , author Charles Wheelan wrote "We Chicagoans can drive around the city and literally point to things that Rosty built." Although Rostenkowski never "literally" built anything with his own money or labor, he delivered federal funds for Chicago and the State of Illinois. Some of his notable projects include: securing $32 million for the Blue Line of the Chicago Transit Authority which expanded travel from the Chicago Loop to O'Hare International Airport, $450 million to repave and expand the Kennedy Expressway, $25 million to fix the dangerous S Curve on Lake Shore Drive $4 billion for the Deep Tunnel Project, which was designed to keep raw sewage from entering the Chicago River and Lake Michigan, while also protecting over half a million suburban and city home owners threatened by flooded basements. He followed that with $42.4 million for reservoirs in McCook and Thornton Townships and by O'Hare airport, $16.8 million for downtown's State Street Mall renovation, $3.5 million for the construction of the Cook County Boot Camp, a military-style alternative for first-time youthful offenders. When the Chicago White Sox baseball team was considering moving to Florida, Rostenkowski secured a $150 million bond authority for the construction of US Cellular Field. Once nearly abandoned and left in disrepair, he ensured $75 million in tax-free bonds for the remodeling of Navy Pier, which today has become Chicago's preeminent tourist attraction. To ease erosion that threatened Lake Shore Drive and several harbors and museums along the Chicago lake front, Rostenkowski secured $2.2 million for the Chicago Shoreline Protection Project, and laid the foundation for a coordinated partnership among the Army Corps of Engineers, the federal government and the City of Chicago. He also was responsible for securing funding for the upkeep of Chicago area bridges including the Chicago Skyway, the Division, Cermak, and Roosevelt street bridges.
 Passage 2:Kifle was born in Adi Billai in Eritrea's Debub Region. He made his first international appearance for Eritrea at the age of 21, running in the 3000 metres at the 1999 IAAF World Indoor Championships. He finished in last place and was over twenty seconds behind the rest of the runners. His first international outdoor competition followed later that year and he ran in the heats of the 5000 metres at the 1999 World Championships in Athletics in Seville. In 2000 he came 61st at the 2000 IAAF World Cross Country Championships and made his Olympic debut with a performance in the heats of the 10,000 metres at the 2000 Sydney Olympics. He began to improve from the 2002 season onwards: he was eighth in the long race at the 2000 IAAF World Cross Country Championships, fourth at the 2002 IAAF World Half Marathon Championships with a time of 1:01:05 hours, and came sixth over 5000 m at the 2002 African Championships in Athletics. He also won the Cursa de Bombers 10K in Spain that year.
 Passage 3:During the Battle of Gettysburg, the dirt Wheatfield Road was used by various Union and Confederate troops (e.g., Crawford's Third Division of Pennsylvania Reserves), and Union troops deployed artillery westward to the Peach Orchard using the road. In 1884, the Round Top Branch's wye with double spurs and station was built at the east end of Wheatfield Road, and in 1894 the Gettysburg Electric Railway was laid along a west portion of the road (trolleys also crossed the east end near Round Top Station). In 1895, the Commonwealth of Pennsylvania ceded jurisdiction of Wheatfield Road to the War Department, and in 1900 two cast iron identification tablets were placed to label the road. The Gettysburg Electric Railway tracks were removed from the Wheatfield Road in 1917 and the road was repaired in 1931. The Wheatfield Road was resurfaced with asphalt west of Sykes Avenue in 1933, and completed "from the Rosensteel pavilion to the Taneytown road" in 1940 by the McMillan Woods Civilian Conservation Corps camp.
