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 after Gene Haas formed his NASCAR Sprint Cup Series team did he form his Haas F1 Team? Passage 1:Several team changes took place before the season began. Haas F1 Team, a team formed by NASCAR Sprint Cup Series team owner Gene Haas, joined the Formula One grid, becoming the first American team to compete since the unrelated Haas Lola team competed in 1986. The team used power units supplied by Ferrari and a chassis developed by Dallara. Dallara had last participated in Formula One as the chassis manufacturer for HRT in . Renault returned to Formula One as a full factory-supported team after they purchased Lotus from Genii Capital, the venture capital firm they had originally sold the same team to in 2010, and supplied engines to up until the end of . Lotus's participation in the 2016 season was in question pending the resolution of a High Court case brought against the team by HM Revenue and Customs over unpaid PAYE tax.
 Passage 2:Okazaki-shuku was a part of the flourishing castle town surrounding Okazaki Castle, the headquarters for Okazaki Domain. The classic ukiyo-e print by Andō Hiroshige (Hōeidō edition) from 1831 to 1834 depicts a Yahagibashi, one of the few bridges permitted by the Tokugawa shogunate on the Tōkaidō, and one of the longest bridges built in Japan during the early Edo period. Okazaki Castle is depicted in the distance on the far shore of the river. Following the Meiji restoration, with the construction of railroads, the route of what became the Tokaido Main Line was laid down through the nearby village of Hane ( Hane-mura) to the south. Unlike Goyu-shuku and Akasaka-juku, but this did not cause a huge economic decline to Okazaki-shuku. There was a horse-drawn rail line connecting Okazaki to the train station, as well as a teachers' school, which kept the town alive. On the other hand, Okazaki was not able to compete with the growth of Toyohashi, which was located directly on the railway, and which gained city-status first. Because of fires during World War II and the subsequent rebuilding of Okazaki in the post-war years, there are few remnants of the post town remaining today.
 Passage 3:Before the station house was built rail service to Chatham started on December 21, 1841 when the first portion of the Albany and West Stockbridge Railroad was put into service between Greenbush (east of Albany) and Chatham. The Harlem Extension of the New York and Harlem Railroad was built to Chatham by 1869. By late 1870 a series of company mergers led to the formation of the Boston and Albany Railroad (B&A). In 1881 the B&A hired Henry Hobson Richardson to design several stations for the railroad. Richardson died unexpectedly in 1886 and the remaining station design work was transferred to the Boston-based architecture firm of Shepley, Rutan and Coolidge. They designed the Chatham Station which was opened for service along the B&A's Boston to Albany line in 1887. The Richardsonian Romanesque building features a Dutch gable roof with wide eaves and colonnade porticos that extend out east and west along the tracks over the low platform. The walls are made of lightly colored rusticated stone with window and door frames, sills, and lintels of contrasting brownstone. A prominent bow window faces trackside and once was used as part of the stationmaster's office.
