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.

Question: How wide is the body of water that Evel Knievel attempted to jump across? Passage 1:Golden turned professional in 1915 and was an assistant pro and later head pro at the Tuxedo Club until 1929 when he took the head job at North Jersey Country Club in Paterson, New Jersey. During his time at the Tuxedo Club, he was a three-time semifinalist in the PGA Championship. In 1922, he lost to Emmet French. In 1926, he dropped a semifinal match to Leo Diegel, and the following year he lost in the semis to Joe Turnesa. Golden remained in Paterson for just a year, leaving for the head professional job at Wee Burn Country Club near Darien, Connecticut. While serving as the pro at Wee Burn, Golden won four consecutive Connecticut Open titles (1932–35), with the 1932, 1933 and 1935 events part of the official PGA schedule. His most lucrative win came in 1931, at the Agua Caliente Open in Mexico. Golden finished regulation tied with George Von Elm at 293. The duo agreed prior to the playoff to split first- and second-prize money, a common practice, with each player pocketing $6,750. Golden went on to win the playoff. Without the agreement, he would have won $10,000.
 Passage 2:ABC's Wide World of Sports was unwilling to pay the price Knievel wanted for the Snake River Canyon jump, so he hired boxing promoter Bob Arum's company, Top Rank Productions, to put the event on closed-circuit television and broadcast to movie Investors in the event took a substantial loss, including promoter Don E. Branker, as well as Vince McMahon of what was then called the World Wrestling Federation. Arum partnered with Invest West Sports, Shelly Saltman's company, to secure from Invest West Sports two things: first, the necessary financing for the jump, and second, the services of Saltman, long recognized as one of America's premier public relations and promotion men, to do publicity so that Knievel could concentrate on his jumps. Knievel hired subcontractor and aeronautical engineer Doug Malewicki to build him a rocket-powered cycle to jump across the Snake River, and called it the Skycycle X-1. Malwecki's creation was powered by a steam engine built by former Aerojet engineer Robert Truax. On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp. The decision was then made to have Truax build the Skycycle X-2 and have it take off and fly more like a rocket than a motorcycle.
