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: When did the team that is now the Washington Nationals leave Montreal? Passage 1:Since about 560, the Avars had ruled over large parts of the Pannonian Basin and Carantania southeast of Francia, though in the last decades, the Avar Khaganate had to deal with Bulgarian and Croat incursions. To secure the frontier of his empire and the traffic on the trade routes to the east, Charlemagne allied with Khan Krum of Bulgaria and the Croatian duke Vojnomir, and from 791 launched several campaigns against the Avars, where he, according to the Vita Karoli Magni, encountered only modest opposition. In 796 Carolingian forces under Charlemagne's son Pepin of Italy destroyed the main Avar fortress called the Ring of the Avars and made the Khagan a Frankish vassal, while the remaining Avars retreated behind the Tisza River. The victory is perpetuated by the poem De Pippini regis Victoria Avarica. 
 Passage 2:The Washington Nationals' 2012 season was the eighth season for the baseball franchise of Major League Baseball in the District of Columbia, the fifth season at Nationals Park, and the 44th since the original team was started in Montreal, Quebec. After finishing the previous season in third place with an 80–81 record, out of last place in the NL East for the second time since moving to Washington, the Nationals made several moves to pursue playoff contention in 2012 and beyond. Despite being plagued with injuries, the Nationals had an impressive start to the season, never dropping below the .500 mark and consistently holding first or second place in their division. On September 3, the Nationals won their 82nd game of the season, making this season their first winning season since moving to Washington, D.C. in 2005 and the first for the franchise since 2003. On September 20, the Nationals beat the Los Angeles Dodgers to clinch the franchise's first postseason berth since 1981, and the first for a Washington-based team since the Washington Senators won the American League pennant in 1933. On October 1, the Nationals clinched the National League East division. On October 3, they went on to clinch the best record in Major League Baseball at 98-64. They finished the season with a 98-64 record and played the St. Louis Cardinals in the Divisional Series. On October 12, in Game 5 of the NLDS, they lost to the Cardinals 9-7 and were eliminated.
 Passage 3:On 16 June 2013, in a series of telephone interviews Kinnear claimed he had been appointed as director of football for Newcastle United. In a Talksport interview over the telephone on 17 June 2013, Kinnear claimed to have replaced someone called "Derek Lambesi" (sic) as the club's director of football, signed Dean Holdsworth at Wimbledon for £50,000 (actually £650,000), sold Robbie Earle (retired a year after Kinnear left), signed goalkeeper Tim Krul when he was previously manager (actually signed by Graeme Souness three years prior) and has been awarded the LMA Manager of the Year award three times despite only winning the award once, he also said he'd never been sacked in his life. Kinnear claimed to have signed John Hartson on a free when he in fact paid £7.5 million for the striker. He also mispronounced the names of Yohan Cabaye, Hatem Ben Arfa, Shola Ameobi and others in the Talksport interview. The appointment, a three-year contract, was confirmed by Newcastle United on 18 June. The confusion around Kinnear's appointment to the role was criticised by former club chairman Freddy Shepherd in an interview with BBC Sport. Kinnear drew criticism when the 2013 summer transfer window closed with Kinnear failing to make a single permanent signing, lone recruit Loïc Rémy having been signed on loan from Queens Park Rangers. This criticism intensified at the end of the 2014 winter transfer window with Kinnear failing again to make a permanent signing, this after the £20 million sale of midfielder Yohan Cabaye, with Luuk de Jong having been brought in on loan from Borussia Mönchengladbach.
