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.

Example Input: Question: How long had the London Stock Exchange been in existence for by the year Hamilton quit his membership there? Passage 1:Hamilton followed his mother as a Christian Scientist, and attended Claremont Fan Court School and then Eton College. He did National Service in the Coldstream Guards from 1955 to 1958. His father had been wounded while serving with the same regiment in the Second World War. Hamilton then worked in the City of London as a gilts broker. He was a member of the London Stock Exchange from 1967 to 1980. He remained in the City for only a short period, leaving when he inherited two estates from his father's cousin. He married his wife, Corinna Dixon, in 1967, and they had four sons together. He succeeded his father as Baron Hamilton of Dalzell in 1990, inheriting land near and properties in the village of Betchworth in Surrey, and a Regency mansion.
 Passage 2:As a backbencher in Ralph Klein's Progressive Conservative caucus, Knight moved a number of government bills. The first was 2003's Electric Utilities Act, which made some changes to the government's deregulation of the province's electricity market. Much of the debate around the bill was about whether the government's deregulation had worked well to date. The bill was passed on a party line vote, with Knight's fellow Progressive Conservatives voting unanimously in favour and the opposition Liberals and New Democrats voting unanimously against. Knight also sponsored the Securities Amendment Acts, separate bills with the same name from different years, 2005 and 2006. The first of these was designed to harmonize the securities regulation with that of other provinces. It was supported by Liberals Rick Miller and Bill Bonko, who considered it a step in the right direction. New Democrats gave it a mixed reception, with Ray Martin agreeing that it did make some improvements, but with his colleague David Eggen trying to kill it on third reading, saying that what was needed was a supra-provincial securities regulator. The 2006 edition of the Securities Amendment Act implemented further harmonization, and passed with little debate. The Securities Transfer Act of the same year consolidated and harmonized the province's rules for transferring securities, and passed with all-party support.
 Passage 3:On January 13, UFC revealed this event was originally intended to take place at Arena da Baixada (a much larger venue) in Curitiba, Brazil, and feature a UFC Heavyweight Championship rematch between champion Fabrício Werdum and former two-time champion Cain Velasquez, with former UFC Middleweight Champion Anderson Silva in the co-main event slot, possibly against Michael Bisping. Due to a series of injuries, the company moved the heavyweight bout to a separate event scheduled for February 6, which at that time was . This change made the March 5 event a smaller draw, which led to the transition to the smaller venue in Rio de Janeiro. To maintain local interest, the company then considered booking the main event as a rematch between two Brazilian fighters, Silva and former UFC Light Heavyweight Champion Vitor Belfort. Belfort declined the bout, as he wished to wait for the result of the middleweight title fight at UFC 194. This final fall-through is what prompted the cancellation of the event in Brazil and relocation to Las Vegas. On January 27, it was revealed the Werdum-Velasquez bout (which had been moved to "UFC 196" scheduled for February 6, 2016) was cancelled entirely. This forced that event to alter into a "UFC Fight Night" card, and the originally scheduled "UFC 197" event was renamed UFC 196.

Example Input: Question: Who is the head of the National Basketball Association? Passage 1:The Hoyas′ previous season had been a disappointing one in which the relatively young and experienced Georgetown team had fallen from a Top Ten ranking in early January 2009 to a 16–15 finish in March that ended with the loss of 12 out of 16 games and first-round exits from both the 2009 Big East Tournament and the 2009 National Invitation Tournament. The Hoyas had lost starting forward DaJuan Summers after the end of the season when he chose to forego his senior year of college and enter the 2009 National Basketball Association draft, as well as starting guard Jessie Sapp, who graduated, and reserve guard/forward Omar Wattad, who transferred. But with freshman forwards Jerrelle Benimon and Hollis Thompson joining the team and sophomore starting center Greg Monroe, junior reserve center Henry Sims, junior starting guards Austin Freeman and Chris Wright, junior reserve forward Julian Vaughn, and sophomore reserve forward Jason Clark all returning, the Hoyas expected to bounce back in 2009–10. The preseason Associated Press Poll ranked them No. 20.
 Passage 2:Lewald was born in 1860; his aunt was Jewish novelist Fanny Lewald. Lewald became a civil servant in Prussia in 1885, and became the acting Reich Commissioner in 1903. In that role, Lewald attended the 1904 Worlds Fair (held along with the Olympic Games), where he disagreed with Kaiser Wilhelm II over whether the Deutscher Olympischer Sportbund, of which he was the President, should be politically independent. After Berlin won the right to stage the 1916 Summer Olympics (which were later cancelled due to the outbreak of World War I), Lewald encouraged the German Reich to invest in the games, arguing that it was comparable to a World Trade Exhibition. Lewald retired from government in 1923; he had been the under Secretary of State. In 1935, Lewald recommended that Pierre de Coubertin be awarded a Nobel Prize.
 Passage 3:The 1993–94 NBA season was the Spurs' 18th season in the National Basketball Association, and 27th season as a franchise. It was also their first season at the Alamodome. During the offseason, the Spurs acquired All-Star forward Dennis Rodman from the Detroit Pistons, and signed free agent Sleepy Floyd. Rodman led the league with 17.6 rebounds per game as the Spurs went on an 8-game winning streak after a 4–5 start to the season. The team would then win 13 consecutive games between January and February, and finish second in the Midwest Division with a 55–27 record. David Robinson captured the scoring title leading the league with 29.8 points per game, and was selected for the 1994 NBA All-Star Game. However, in the first round of the playoffs, Rodman became a distraction as he scuffled with head coach John Lucas as the Spurs lost to the 5th-seeded Utah Jazz in four games.

Example Input: Question: What venue was the Madrid open at? Passage 1:Anderson did not play again on tour until May at the Madrid Open. He lost in the first round against 13th seed Gaël Monfils. Anderson then played in Rome as the 16th seed. Anderson won his first-round match against Feliciano López, but lost in the second round to Juan Mónaco, despite winning the first set. Anderson then competed in Nice as the third seed. He defeated qualifier Diego Schwartzman, before losing to fifth seed João Sousa. Anderson then played at the French Open as the 18th seed, where he lost in the first round to Stéphane Robert. Anderson started his grass season at Queen's Club. Since he entered late, he had to go through qualifying. Anderson defeated Edward Corrie and Jiří Veselý, both in straight sets, to enter the main draw. He then lost to Bernard Tomic in the first round of the main draw. Anderson then played at Nottingham as the top seed. He defeated Ivan Dodig and 14th seed Fernando Verdasco to reach the quarterfinals, where he lost to sixth seed and eventual champion Steve Johnson. Anderson then played at Wimbledon as the 20th seed. He lost in the first round to Denis Istomin, despite winning the first two sets.
 Passage 2:Christopher William "Will" Gill, BFA (born July 5, 1968) is a Canadian contemporary artist known for his wide-ranging works in sculpture, painting, photography and video. Born and raised in Ottawa, Ontario, Canada, he received his Bachelor of Fine Arts in 1991 from Mount Allison University, where he studied sculpture and printmaking. In 1997 he moved to St. John's, Newfoundland. "Some of Gill's notable works have drawn upon the Newfoundland landscape. In the 2009 performance Cape Spear, he tossed fibreglass-encased glow sticks off of the easternmost point of North America using a catapult." "The 2009 installation Bareneed is a replica of a cast-iron bathtub that Gill saw on the bottom of the ocean floor while sea-kayaking near the titular coastal community (the artist himself has noted that the St. John's setting has been key to his art production)." Gill was longlisted for the Sobey Art Award in 2004 and 2006. In March 2013, Gill was selected from a group of 31 artists to create an indoor public art installation in the lobby of a new office building in St. John's, set to open in the spring of 2014 - the first private juried art commission in the province awarded to a local artist. From June to November 2013 he exhibited along with artist Peter Wilkins as part of an official Collateral Project at the 2013 Venice Biennale.
 Passage 3:After a brief period in the diplomatic service, Himmatsinhji returned to the army, seeing service in the Second World War. A war-substantive lieutenant-colonel at the war's end, he eventually reached the rank of major-general. He was appointed a Companion of the Order of the Indian Empire (CIE) in the 1946 New Year Honours. He was elected to the Central Legislative Assembly, India's pre-independence lower house, in 1946, and was later a member of the Constituent Assembly, the transitional body established after independence. A member of the Indian National Congress, he was a party whip before being appointed Deputy Minister of Defence in Jawaharlal Nehru's first ministry. In this position he chaired a committee responsible for recommended improvements to India's defences along its border with what was then the Kingdom of Tibet, prior to China's invasion and eventually annexation. Upon retirement, Himmatsinhji was appointed the first lieutenant-governor of Himachal Pradesh, a newly created Part C state of India. He served in the position from 1952 to 1954, when he was succeeded by Bajrang Bahadur Singh. Himmatsinhji died in January 1973.
