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.

The question refers to the 704th unit and task about war which is decribed by Passage 1.

New input case for you: Question: How many years after the disappearance of Quentovic was Étaples established? Passage 1:To meet the new requirement, George William Patchett, the chief designer at the Sterling Armaments Company of Dagenham, submitted a sample weapon of new design in early 1944. The first Patchett prototype gun was similar to the Sten insofar as its cocking handle (and the slot it moved back and forth in) was placed in line of sight with the ejection port though it was redesigned soon afterwards and moved up to a slightly offset position. The army quickly recognised the Patchett's potential (i.e. significantly increased accuracy and reliability when compared with the Sten) and ordered 120 examples for trials. Towards the end of the Second World War, some of these trial samples were used in combat by airborne troops during the battle of Arnhem and by special forces at other locations in Northern Europe where it was officially known as the Patchett Machine Carbine Mk 1. For example, a Patchett submachine gun (serial numbered 078 and now held by the Imperial War Museum), was carried in action by Colonel Robert W.P. Dawson while he was Commanding Officer of No. 4 Commando, during the attack on Walcheren as part of Operation Infatuate in November 1944. Because the Patchett/Sterling can use straight Sten submachine gun magazines as well as the curved Sterling design, there were no interoperability problems.
 Passage 2:Quentovic was a Frankish emporium in the Early Middle Ages that was located on the European continent close to the English Channel. The town no longer exists, but it was thought to have been situated near the mouth of the Canche River in what is today the French commune of Étaples. Archaeological discoveries led by David Hill in the 1980s found that the actual location of Quentovic was east of Étaples, in what is now the commune of La Calotterie. It was an important trading place for the Franks and its port linked the continent to England, specifically to the southeastern county of Kent. From what we know today, Quentovic was founded by a Neustrian king in the early 6th century. It was one of the two most prominent Frankish ports in the north (the other being Dorestad) until it was abandoned, probably in the 11th century. Merchants were drawn to this place because the number of trading posts at the time was limited. Quentovic was also the place where Anglo-Saxon monks would cross the English Channel on their pilgrimage to Rome. A lack of physical evidence, and the sudden disappearance of this emporium, make the town difficult to interpret. Some of the most important historical evidence on Quentovic comes from documents of taxation and especially through the town's minting of coinage. Coins minted during both the Merovingian and the Carolingian dynasties have been found.
 Passage 3:The popularity of DC's and Marvel's Silver Age superhero titles led Archie Comics to revive their own line of superhero comics. The Archie Adventure line began with titles centered on The Fly, The Jaguar, and a superheroic/spy version of the 1930s pulp character The Shadow. After suggestions and fan-art began suggesting a team made up of the characters published by Archie Comics precursor MLJ in the 1940s, Archie's superhero imprint, soon retitled Mighty Comics, re-introduced many of these characters, and brought them together in several issues of Fly Man. This team, which followed the success of The Avengers and the Justice League of America, was made up of The Shield, The Fly (re-dubbed Fly-Man), The Black Hood, and The Comet. Calling themselves The Mighty Crusaders, they initially came together as part of a plan by The Fly's nemesis The Spider to trap the hero. After appearing as a team for two more issues of Fly Man, and gaining Flygirl as a member in the process, they spun off into their own series, The Mighty Crusaders, which ran bimonthly for 7 issues. The Archie series mixed typical superhero fare with high camp. Don Markstein writes that they touched on "all the genre's cliches of the time", with Siegel's writing on the book being a "hokey rendition of Stan Lee".
