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.

Let me give you an 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.

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

OK. solve this:
Question: How old was the businessman that Nobel signed an agreement with in Berlin? Passage 1:Emanuel Nobel was a very forward-looking businessman, just like his father, who had instigated the construction of Russia's first pipeline and the world's first oil tanker in 1878, as well as the world's first railway tank cars in 1883. On 16 February 1898 Emanuel signed a licence agreement in Berlin with Rudolf Diesel, after having heard Diesel describing his new engine in a public lecture. The agreement allowed Nobel to build the world's first diesel engine plant in St Petersburg, and the engines were used to propel Branobel's fleet of oil tankers. Emanuel led Baku to a dominating role in the global oil industry and Branobel activities soon developed throughout the Caspian Sea, operating also in Grozny and Dosser.
 Passage 2:Dean Clark took over as head coach shortly after James' resignation, and led the 1997–98 Hitmen to a remarkable turnaround. The team improved to a 40–28–4 record and first-place finish in the Central Division, qualifying for the playoffs for the first time in franchise history. They defeated the Saskatoon Blades and Swift Current Broncos to reach the Eastern Conference final before falling to the Brandon Wheat Kings. Clark was awarded the Dunc McCallum Memorial Trophy as the WHL's top coach, and also won the Canadian Hockey League's Brian Kilrea Coach of the Year Award. Calgary improved to 51–13–8 in 1998–99, finishing one point ahead of the Kamloops Blazers for the regular season title. Led by Brad Moran, Pavel Brendl and goaltender Alexandre Fomitchev, the Hitmen lost just five games in the playoffs en route to their first league championship. They won the title at home before a WHL playoff record crowd of 17,139. They became the first Calgary-based team to qualify for the Memorial Cup since the Calgary Canadians won the 1926 title.
 Passage 3:Secondly, those teams who had backed out of the 1982 San Marino boycott were harshly dealt with. The Tyrrell team was the last team to obtain a turbocharged engine contract (essential in order to be competitive in Formula One from 1983 onward), finally signing a deal to run "customer" Renault turbos in the latter part of 1985 (roughly three years before turbo engines were ultimately banned). Toleman was effectively squeezed out of the Formula One world championship in 1985 when their tyre supplier pulled out of Formula One. In both cases, it must be said, the teams had previously blotted their copybook with inappropriate acts. In Tyrrell's case, they had backed out of a 1974 contract to run Renault turbo engines, leading directly to the carmaker's entry into Formula One as a factory team in 1977. While in Toleman's case, they broke a Pirelli tyre contract in favour of Michelin tyres in 1984, only to be left without a contract when Michelin withdrew at the end of 1984. Pirelli, understandably, felt they could not reasonably supply the team in 1985. Goodyear, the other supplier, refused to do so on grounds of capacity. This was resolved before the Monaco Grand Prix in 1985, when Toleman bought the Pirelli contract from the recently closed Spirit team, after signing a long-term sponsorship with Luciano Benetton.
