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.

New input: Question: How many years had the Comedy Theatre been in operation for by the year Journey's End was revived in London? Passage 1:In 2004, the play was again revived in London, directed by David Grindley. From its initial twelve-week season at the Comedy Theatre from January 2004, it transferred to the Playhouse Theatre and the Duke of York's Theatre, finally closing on 18 February 2005. A touring company took the same production to over 30 venues across Britain in 2004 and 2005 and back to London, to the New Ambassadors Theatre from September 2005 to January 2006. Grindley's production received its Broadway debut in 2007. Starring Hugh Dancy, Boyd Gaines, Jefferson Mays and Stark Sands, it opened in New York at the Belasco Theatre on 22 February 2007 and closed on 10 June after 125 performances. Grindley's production was revived in 2011 for a UK tour from March to June, and transferred to the Duke of York's Theatre in the West End from July to September. The Sell A Door Theatre Company ran this play at the Greenwich Theatre until 17 February 2013. During 2014 it was presented at the Octagon Theatre, Bolton; directed by David Thacker, it featured David Birrell, Richard Graham and, as Stanhope, James Dutton.
 Passage 2:Over her career, Moore met numerous wealthy and famous people for TV interviews, which was quite easy for journalists and TV personalities during a time before satellite became a common way of conducting interviews. Out of all the people she's met, it was former Pensacola resident and friend Leif Erickson of the NBC western "The High Chaparral" who helped keep Dot's relationship with the network's stars alive for years to come. With such a Hollywood connection came a few roles on television, including Erickson's program and the show Movin' On with Claude Akins, another one of Dot's many guests (Movin' On was filmed on location once in Mobile and its surrounding areas). Besides people, Dot had an encounter with a Bengal tiger and its trainer, which went through fairly well despite a wet moment that would make Johnny Carson and the monkey he encountered laugh. All good things would come to an end in 1985, when NBC ended Moore's flights to visit the famous and must settle with the network's newly installed satellite technology to keep in touch, but there were exceptions. Art Linkletter and Jock Mahoney were Dot's first celebrated guests three weeks into her show's run. The "People Are Funny" emcee and the "Yancy Derringer" star happened to be in Mobile the same day. Ed McMahon made a visit to Mobile for the America's Junior Miss national finals in May 1973, plus he made a stop at WALA to appear on Moore's tenth anniversary show on May 14. "And now, here's Dottie!" was Ed's introduction for his friend Dot as she was getting ready to go on the air, which came as such a surprise that it never made it into the show's taping. 
 Passage 3:Benjamin Thompson was a Loyalist during the American Revolution, and fled the country in 1775 when the British evacuated Boston. He returned late in the Rev War commanding the King's American Dragoons, who saw action in the Southern states. He returned to England after the British surrender. He eventually settled for a time in the Holy Roman Empire, where he acquired the title of Count Rumford, and where he performed his groundbreaking research into the design of heating systems. This research resulted in a series of improvements to home heating systems, notably the Rumford stove, a shallow fireplace that more efficiently projected heat into a room than older and larger fireplaces. While in Munich, Thompson oversaw reforms of the indigent welfare system of Bavaria, and designed the city's famous English Garden. Thompson was also an inveterate and practical tinkerer, developing new versions of everyday utensils. He also proposed in 1799 the establishment in the United Kingdom of a research organization, which resulted in the founding of the Royal Institution. Although he never returned to the country of his birth, he did endow a professorial chair at Harvard College, and established the Rumford Prize, an annual award given by the American Academy of Arts and Sciences. He died in Paris in 1814.
