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 flights per year depart from the airport where Spirit Airlines moved to in 2001? Passage 1:Friedman graduated from the University of Houston with a degree in philosophy in 1956. During his career, he wrote for the Houston Chronicle, the Detroit Free Press, Newsday, and for Knight Ridder newspapers. He won a 1963 Nieman Fellowship. His work landed him on the master list of Nixon political opponents. He was one member of a team that covered the 1967 Detroit riot for the Detroit Free Press. Next year they shared the Pulitzer Prize in Local General or Spot News Reporting (a predecessor of the Breaking News Pulitzer), citing "both the brilliance of its detailed spot news staff work and its swift and accurate investigation into the underlying causes of the tragedy." Friedman also taught national and foreign affairs reporting at the Columbia University Graduate School of Journalism for a year. In 1985, Friedman and his family moved to Edgewater, Maryland, where Friedman worked as a White House correspondent. Friedman began working for Newsday, although he left to spend five months in South Africa teaching journalists. After his return, Friedman wrote a weekly column called "Gray Matters" that covered issues affecting older people. After working there for more than twenty years, he quit Newsday in October 2009 over its decision to charge for its web content. He began publishing his column in November 2009 in Time Goes By, a blog.
 Passage 2:Dagan was conscripted into the Israel Defense Forces (IDF) in 1963. He was considered for the elite Sayeret Matkal unit, but ended up joining the Paratroopers Brigade. He completed his compulsory service in 1966, but was called up as a reservist in 1967, and fought in the Six-Day War as an officer, commanding a paratrooper platoon on the Sinai front. In the early 1970s, he commanded an ad hoc undercover commando unit, known as Sayeret Rimon, whose task was to combat the increasing violence in the Palestinian territories. In 1971, he received a Medal of Courage for tackling a wanted terrorist who was holding a live grenade. Dagan later fought in the 1973 Yom Kippur War as an officer on the Sinai front, and participated in the crossing of the Suez Canal. During the 1982 Lebanon War, he commanded the Barak Armored Brigade, and was one of the first brigade commanders to enter Beirut. In the 1990s, he held a series of high-level positions in the IDF command, eventually reaching the rank of Major General before retiring from the army in 1995, after 32 years of service.
 Passage 3:In later years, Continental Express continued to serve the airport with nonstop regional jet flights to Cleveland while Continental Connection was operating nonstop turboprop flights to Albany, NY; however, both services ended in 2005. Spirit Airlines scheduled flights to several Florida cities and Detroit, before moving to LaGuardia Airport in 2001; in May 2008 the airline resumed service to Fort Lauderdale from MacArthur only to drop it soon after. Delta Express, which had nonstops to Orlando and Fort Lauderdale, dropped MacArthur Airport in 2003 after a decline in traffic. Delta Connection regional jet service to Atlanta flown by Atlantic Southeast Airlines (ASA) on behalf of Delta Air Lines ended on May 1, 2008 following a mid-April announcement that Delta and Northwest Airlines were planning to merge – a move that led to changes for the merged airline.
