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-Lo 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 (18941973) 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 years after World War I started was the Treaty of Versalilles signed? Passage 1:Autechre use many different digital synths and a few analogue synths in their production, as well as analogue and digital drum machines, mixers, effects units and samplers. They have also made extensive use of a variety of computer based sequencers, software synthesisers, and other applications as a means of controlling those synths and processing the synthesised sounds. Much of the hardware and software they use has been customised by the band themselves. Autechre have also experimented in depth with development environments such as Max/MSP, and Kyma, amongst others, from 1997 onwards. From 2005 until 2009, they have used the Elektron Machinedrum and Monomachine, alongside Akai MPC and Nord Modular in their live performances. It has also been rumoured that Autechre have used military equipment in their work. In 2008, Sean Booth reported that if he were locked in a cell for a year with only one piece of software and one piece of hardware, he'd "probably take a copy of Digital Performer and an AKG C 1000 microphone." Other machines that Autechre have repeatedly mentioned in interviews are appreciated for their interface and aesthetics as much as their sound, including the Roland TR-606 and MC-202, and the Nord Lead. According to the 2016 interview to Resident Advisor, both members haven't bought a piece of equipment "in the last 5 years", making MAX/MSP a primary production method, with Sean Booth stating that "in Max I can generally build the thing I need, and if I don't know how to do that it'll generally be worthwhile learning."
Passage 2:A part of the Province of East Prussia until after World War I, in 1920 Nemirseta was with the Klaipeda Region (Memelland) separated from Germany according to the Treaty of Versailles. It was put under administration of the League of Nations and controlled by French forces, until the 1923 Klaipeda Revolt, after which it was annexed by Lithuania. For a brief period Nemirseta again became a border checkpoint, when Lithuanian Foreign Minister Juozas Urbsys under pressure of Nazi Germany in March 1939 signed an agreement after which the Klaipeda Region was reannexed to the German nation. The secret protocol of the MolotovRibbentrop Pact allocated it to the German sphere of influence.
Passage 3:Jackson ran again in 1828, defeating Adams in a landslide. Jackson faced the threat of secession by South Carolina over what opponents called the "Tariff of Abominations." The crisis was defused when the tariff was amended, and Jackson threatened the use of military force if South Carolina attempted to secede. In Congress, Henry Clay led the effort to reauthorize the Second Bank of the United States. Jackson, regarding the Bank as a corrupt institution, vetoed the renewal of its charter. After a lengthy struggle, Jackson and his allies thoroughly dismantled the Bank. In 1835, Jackson became the only president to completely pay off the national debt, fulfilling a longtime goal. His presidency marked the beginning of the ascendancy of the party "spoils system" in American politics. In 1830, Jackson signed the Indian Removal Act, which forcibly relocated most members of the Native American tribes in the South to Indian Territory. The relocation process dispossessed the Indians and resulted in widespread death and disease. Jackson opposed the abolitionist movement, which grew stronger in his second term. In foreign affairs, Jackson's administration concluded a "most favored nation" treaty with Great Britain, settled claims of damages against France from the Napoleonic Wars, and recognized the Republic of Texas. In January 1835, he survived the first assassination attempt on a sitting president.
