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.

Let me give you an 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.

Question: Who long did the Russian internal conflict where women fought on both sides last? Passage 1:In 1966/67 she went to Puerto Rico, where she worked in the Anti-Poverty Programs of the Office of Economic Opportunity. From 1969 to 1970, she taught seminars on women's studies and on race and class at Columbia College Chicago and was active in the women’s movement. In 1972 Schultz was awarded a Ph.D. at University of Wisconsin–Madison. In 1973 she returned to Germany and taught women's studies and cultural and immigration issues at the John F. Kennedy Institute for North American Studies at the Free University of Berlin. Alongside, she established together with a few fellow campaigners a book publishing house specialized on feminist literature and a feminist women's health center in 1974. As a visiting professor, she taught sociology of education at State University of New York in 1981. In 1984, she helped civil rights activist and poet Audre Lorde, whom she got to know at the 1980 UN World Conference on Women in Copenhagen, to become a visiting professor at FU Berlin.

 Passage 2:The final was played under floodlights at the Sir Vivian Richards Stadium, in North Sound, Antigua, roughly a 15-minute drive north of the country's capital city, St. John's. The stadium had not been used during the group stage of the tournament, but hosted both semi-finals prior to the final. A crowd of over 9,000 attended the match, which began at 20:00 AST () with a scheduled break between the two innings from 21:30 to 21:50; play was due to finish by 23:20. Langton Rusere of Zimbabwe and the South African Shaun George were appointed at on-field umpires for the match, with Gregory Brathwaite as the TV umpire. Nitin Menon served as reserve umpire, while Sir Richie Richardson was the match referee. Rusere's appointment marked the first time that a Zimbabwean had stood in the final of a major international cricket tournament. George had previously umpired in three Women's Cricket World Cup finals, in each of 2005, 2013 and 2017.
 Passage 3:The only nation to deploy female combat troops in substantial numbers was Russia. From the onset, female recruits either joined the military in disguise or were tacitly accepted by their units. The most prominent were a contingent of front-line light cavalry in a Cossack regiment commanded by a female colonel, Alexandra Kudasheva. Others included Maria Bochkareva, who was decorated three times and promoted to senior NCO rank, while The New York Times reported that a group of twelve schoolgirls from Moscow had enlisted together disguised as young men. In 1917, the Provisional Government raised a number of "Women's Battalions", with Bochkareva given an officer's commission in command. They were disbanded before the end of the year. In the later Russian Civil War, they fought both for the Bolsheviks (infantry) and the White Guard.
