You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.

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

New input: Question: How many years passed between Zinoviev fighting against the Basmachi and him getting captured? Passage 1:Ivan Dmitrievich Zinoviev (Russian: Иван Дмитриевич Зиновьев; 17 January 1905 – 1942) was a Red Army colonel and Hero of the Soviet Union. Zinoviev began his military service with the OGPU Border Troops and fought against the Basmachi. He was awarded the title Hero of the Soviet Union and the Order of Lenin for his leadership of a border post during the Winter War. After Operation Barbarossa, Zinoviev became commander of the 393rd Rifle Division and led the division during the Barvenkovo-Lozovaya Operation but was captured and seriously wounded during the Second Battle of Kharkov. Zinoviev was sent to a concentration camp in Germany, then transferred to another camp in Norway, where he tried to escape and was shot.
 Passage 2:Yet another of Krishnamacharya's pupils, K. Pattabhi Jois, came to the United States in 1975, starting a long-lasting craze in the country for Ashtanga Vinyasa Yoga. A vinyasa is a movement that connects yoga poses together; the result is a continuously flowing sequence that can be learnt and practised as a whole, making yoga into an energetic aerobic exercise. Ashtanga Yoga gave rise to various spinoff styles including Power Yoga in the 1990s, with one form created in 1995 by Beryl Bender Birch and others by Bryan Kest, a student of K. Pattabhi Jois, and Baron Baptiste, trained in the hot style of Bikram Yoga. Bikram Choudhury arrived in the United States in 1971, and by 1974 had created his own style of yoga, with the studios heated to . He was strongly charismatic, had been taught yoga by the bodybuilder B. C. Ghosh, Yogananda's youngest brother, and like Jois saw hatha yoga as a religion. The two men made yoga serious, hard work, with an intensity that demanded a lifestyle arranged around yoga; up to that point, it had been seen as a slow, gentle, feminine form of exercise, and classes had consisted mainly of women. Practice was so hot and sweaty, and required such mobility, that clothing was reduced to a new minimum: men often wore nothing but long shorts, while women wore footless leggings, sports bras, and small tank tops.
 Passage 3:In December 2009, with Fisichella having moved to Ferrari and Liuzzi being promoted to the race team, di Resta took part in a test with the team at the Jerez circuit alongside J. R. Hildebrand. At the Autosport International show in January 2010, he was said to be close to a deal as the team's test and reserve driver for the 2010 season. The deal was announced on 2 February. Di Resta made his Formula One race meeting début at the 2010 Australian Grand Prix, where he took part in the first free practice session in place of Sutil and placed 11th. He drove in the first practice sessions of all the following races until Monaco Grand Prix, where he did not take part. He resumed driving for the team at the European Grand Prix and the following British Grand Prix. After sitting out the German Grand Prix he returned for the Hungarian Grand Prix. Di Resta subsequently sat out the Belgian Grand Prix as Tonio Liuzzi and Adrian Sutil needed as much track-time as possible to get the feeling of the new parts. He participated in practice for the Italian Grand Prix, but did not participate in the Singapore or Japanese Grands Prix. The team elected that di Resta should miss the Korean Grand Prix to allow Liuzzi and Sutil to get used to the new track for the race.
