Given the task definition, example input & output, solve the new input case.
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.

New input case for you: Question: What country was Mirche Atsev born? Passage 1:After the fall of the Berlin Wall in Germany in 1989, the organization conducted its first military interventions in Bosnia from 1992 to 1995 and later Yugoslavia in 1999 during the breakup of Yugoslavia. Politically, the organization sought better relations with former Warsaw Pact countries, most of which joined the alliance in 1999 and 2004. , requiring member states to come to the aid of any member state subject to an armed attack, was invoked for the first and only time after the September 11 attacks, after which troops were deployed to Afghanistan under the NATO-led ISAF. The organization has operated a range of additional roles since then, including sending trainers to Iraq, assisting in counter-piracy operations and in 2011 enforcing a no-fly zone over Libya in accordance with UN Security Council Resolution 1973. The less potent Article 4, which merely invokes consultation among NATO members, has been invoked five times following incidents in the Iraq War, Syrian Civil War, and annexation of Crimea.
 Passage 2:State Street continues north through the Crescent neighborhood, past the site of the historic Crescent Elementary School, and enters Downtown Sandy. It intersects 10600 South, which becomes State Route 151 a short distance to the west, and passes a large retail area that includes big box stores and the South Towne Mall. The street climbs a small hill to pass over the Jordan and Salt Lake Canal, then passes a cemetery and a small amount of undeveloped greenfield land near the crossing of Dry Creek before reaching a larger hill into which the East Jordan Canal is carved. At the top of this hill, the street passes west of Jordan High School and the South Towne Expo Center before intersecting 9400 South (former State Route 209). A short distance north of that intersection, the East Jordan Canal passes back under the street on its way toward Holladay, and Rio Tinto Stadium fronts onto the street on the west side. Just before the intersection with 9000 South (modern State Route 209), State Street passes the site of a former smelter (which now has a medical center built on part of it). The street forms the western boundary of the Sandy Historic District from 9000 South to Pioneer Avenue (8530 South), and several historic buildings face onto it in this area. There is a traffic signal it the intersection with Sandy's Main Street at 8720 South. North of the historic district, State Street passes through some relatively lightly developed land near the city's border with Midvale, though there are some townhouse developments in progress in the area.
 Passage 3:Mirche Atsev was born in 1859 in the village of Oreovec in the Prilep district, then part of the Ottoman Empire. He was named after his father, Mirche Atsev, who was a well-known voyvoda. He schooled himself in Prilep and then he worked as a shepherd. After Turks murdered his father, he joined the Hayduk's band of Kone Pavlov in 1885. Houever, in the next year, he was arrested and imprisoned in Solun. After having escaped from the prison, Atsev moved to Bulgaria. During his stay in Sofia, he was accused of involvement in the murder of Stefan Stambolov, as a result of which he was imprisoned for three years in the Black Mosque, (now Sveti Sedmochislenitsi Church). In Sofia, together with his brothers Petar and Georgi, he joined the revolutionary activity of the IMARO against the Turkish authorities. In 1899, Atsev entered with a revolutionary band into Ottomn Macedonia, in the region of Nevrokop. Later, he was a voyvoda in the region in Prilep. In 1901, on the way to the village of Ulanci, in the Tikveš region, his band was chased and crushed by a Turkish military detachment. Mirche Atsev died in this battle.
