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 long did the Croatian War of Independence last? Passage 1:In 1991, the first multi-party elections were held in Croatia, with Franjo Tuđman's win raising nationalist tensions further in an already tense SFR Yugoslavia. The Serb politicians left the Sabor and declared the autonomy of areas that would soon become part of the unrecognized Republic of Serbian Krajina, which had the intention on achieving independence from Croatia. As tensions rose, Croatia declared independence in June 1991. However, the declaration was suspended for three months, until 8 October 1991. The suspension came about as the European Economic Community and the Conference on Security and Cooperation in Europe urged Croatia that it would not be recognized as an independent state because of the possibility of a civil war in Yugoslavia. The tensions escalated into the Croatian War of Independence when the Yugoslav People's Army and various Serb paramilitaries mobilized inside Croatia. On 3 October, the Yugoslav Navy renewed its blockade of the main ports of Croatia. This move followed months of standoff and the capture of Yugoslav military installations in Dalmatia and elsewhere. These events are now known as the Battle of the barracks. That resulted in the capture of significant quantities of weapons, ammunition and other equipment by the Croatian Army, including 150 armoured personnel carriers, 220 tanks and 400 artillery pieces of caliber or larger, 39 barracks and 26 other facilities including two signals centres and a missile base. It also coincided with the end of Operation Coast-91, in which the Yugoslav forces failed to occupy the coastline in an attempt to cut off Dalmatia's access to the rest of Croatia.
 Passage 2:Philippe belonged to the poorer nobility. At first, he served under Luchino Visconti in Lombardy but within a year he entered the service of the husband of Joanna I of Naples, Andrew, Duke of Calabria, who was the son of the King Charles I of Hungary. Andrew was assassinated very soon in September 1345. In the autumn of that year, Philippe set out for the East in the French army. After the Battle of Smyrna in 1346 he was made a knight, and when the French army was disbanded, he made his way to Jerusalem. He realized the advantage which the discipline of the Saracens gave them over the disorderly armies of the West, and conceived the idea of a new order of knighthood, but his efforts proved fruitless. The first sketch of the order was drawn up by him in his Nova religio passionis (1367–1368; revised and enlarged in 1386 and 1396). From Jerusalem he found his way in 1347 to Cyprus to the court of Hugh IV, where he found a kindred enthusiast in the king's son, Peter of Lusignan, then count of Tripoli; but he soon left Cyprus, and had resumed his career as a soldier of fortune when the accession of Peter to the throne of Cyprus (Nov. 1358) and his recognition as king of Jerusalem induced Philippe to return to the island, probably in 1360, when he became chancellor.
 Passage 3:Davies gained a PPE degree from Oxford University in 1974, and started his journalism career in 1976, working as a trainee for the Mirror Group in Plymouth. He then moved to London initially to work for the Sunday People and spent a year working for The Evening Standard before becoming a news reporter at The Guardian in July 1979. Since then he has worked as home affairs correspondent at The Observer; chief feature writer at London Daily News in 1986 and on-screen reporter for World in Action and Channel 4's Dispatches. After the London Daily News folded he moved to the United States for a year, where he wrote White Lies, about the wrongful conviction of a black janitor, Clarence Brandley, for the murder of a white girl. From 1989 Davies was a freelance reporter for The Guardian, for which contributed articles, working from his home in Sussex. He was the winner of the first Martha Gellhorn Prize for Journalism in 1999. In September 2016 he retired, announcing that he would travel in search of interesting experiences. His website states he was last seen somewhere between a yoga shala in Indonesia and a cattle ranch in northern Argentina.
