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 hurricanes did the Atlantic coast see in 1916? Passage 1:He was born in Strasbourg, served in the Breton Volunteers and then came to Nova Scotia as a Foreign Protestants with Edward Cornwallis in 1751. Pernette served as an aide-de-camp during the taking of Quebec City in the Battle of the Plains of Abraham. He first settled at Halifax but later moved to the New Dublin area. He built a gristmill and a sawmill on the LaHave River and also built the first ship on the river. Pernette served as justice of the peace, deputy surveyor and was colonel in the local militia, participating in the defense of Lunenburg during the Raid on Lunenburg, Nova Scotia (1782). He also conducted a census of the area and constructed a road to Lunenburg. Pernette also operated a ferry connecting that road to the road to Liverpool. 
 Passage 2:The 1916 Gulf Coast hurricane was a destructive tropical cyclone that struck the central Gulf Coast of the United States in early July 1916. It generated the highest storm surge on record in Mobile, Alabama, wrought widespread havoc on shipping, and dropped torrential rainfall exceeding . The second tropical cyclone, first hurricane, and first major hurricane – Category 3 or stronger on the modern-day Saffir–Simpson scale – of the highly active 1916 Atlantic hurricane season, the system originated in the southwestern Caribbean Sea on June 28 and moved generally toward the north-northwest. Crossing the Yucatán Channel on July 3 as a strengthening hurricane and brushing Cuba with gusty winds, the cyclone reached its peak intensity with maximum sustained winds of 120 mph (195 km/h) prior to making landfall near Pascagoula, Mississippi, at 20:00 UTC on July 5. Over land, the hurricane rapidly weakened to a tropical storm, but then retained much of its remaining strength as it meandered across interior Mississippi and Alabama for several days, its northward progress impeded by a sprawling high-pressure area to the north. The system weakened into a tropical depression on June 9 and dissipated late the next day over southern Tennessee.
 Passage 3:In the second qualifying session, every driver set a lap on the option tyres except two. Lewis Hamilton still managed to take his McLaren into Q3 with the sixth fastest Q2 time on the prime tyres, and Pastor Maldonado, who did not set a timed lap. It was notable that Red Bull Racing and Ferrari needed to use options when Hamilton could use primes. Jaime Alguersuari – a man who had come from far back to score points a few times in , like his teammate did at this weekend set the slowest Q2 time and dropped out on the same row as Rubens Barrichello's Williams. Neither Renault made the top 10, Vitaly Petrov in 12th and Nick Heidfeld in 14th. One Force India and one Sauber failed to make the cut – Kamui Kobayashi (13th) joined Heidfeld on row 7, and similarly Paul di Resta just missed out with 11th.
