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: What country were US tanks still rolling toward in March of 2003? Passage 1:Wilson was the son of Alexander Robertson Wilson, writer (or solicitor) and town clerk of the then Royal and Ancient Burgh of Irvine, and Elizabeth Wylie Murray. He was born in Irvine. He was named for a great-grandfather, John Gray, who was town clerk of Ayr, and joint secretary of the first Burns festival there in 1844; an uncle 'John Gray Wilson' had died at the age of 14. The John Gray Wilson of this article, the Sheriff, was educated at Irvine Royal Academy; the Edinburgh Academy, where he was Dux (leading scholar) in 1935; and, as an Open Classics Scholar, at Oriel College, Oxford where he graduated B.A.. In the long vacation of 1936 he contracted polio, which left him with a weakened leg and chest, and contributed to his early death. (At the time of this enforced absence, his name was used by a fantasist claiming to have been an aviator during the Spanish Civil War.) After Oxford, he attended Edinburgh University where he received the degree of Bachelor of Laws. In 1943 he married Nan MacAuslan, herself active in the liberal Party and later awarded a PhD by the University of Edinburgh for a Thesis on the Social Anthropology of the Faculty of Advocates. They had three sons.
 Passage 2:MEED was launched in 1957. When Rafiq Hariri drew up plans to rebuild a war-shattered Lebanon, MEED met the prime minister and asked him to explain them. When Colonel Gaddafi unveiled the first part of his Great Manmade River, MEED took a front-row seat at the ceremony and quizzed the engineers. While US tanks were still rolling towards Baghdad in March 2003, MEED obtained plans from Washington that described how the US was hoping to rebuild the country. Three months before going public, MEED revealed DP World's IPO plans. Abdalla el-Badri announced Opec's potential move from US dollar to euro pricing to MEED. MEED broke news of Saudi Arabia moving ahead with plans for a Mile-High Tower in Jeddah – which would make it the tallest tower in the world – and Nakheel's plans to create a tower over one kilometre high (then called Nakheel Tower, later announced as Dubai's Harbour Tower) to trump Emaar's Burj Khalifa.
 Passage 3:Balsdon skips one of the top teams in Ontario. As of 2019, Balsdon has played in 13 provincial championships. He first played at the provincials in 1999, playing for John Base (4th place). He left the Base rink in 2000 to form his own team. He qualified again in 2002 as a skip, again finishing 4th. His next provincial was the 2005 Ontario Kia Cup, where his rink finished 4th once again. He qualified again in 2007, where he once again finished 4th at the 2007 TSC Stores Tankard. His next provincial in 2011 would be more successful. At the 2011 provincial championship, he lost to the (then) five-time defending champion Glenn Howard rink in the final. At the time, Balsdon represented the one-sheet Loonie Curling Club located in Chaffeys Locks, Ontario, north of Kingston. Despite representing the club, he had only played there once. The Loonie was built in 2008, and Balsdon has represented it twice. Balsdon returned to the Tankard in 2012, finishing tied for 8th. Despite battling an injury for much of the season, Baldson won his first provincial men's title in 2014, when his rink defeated Glenn Howard in the Ontario final. The win broke Howard's record eight-year provincial championship streak. The team was named after third Mark Bice who had skipped the team through zone and regional play due to Baldson recovering from a broken rib. However, Balsdon would skip the team in the provincial championship. The team represented Ontario at the 2014 Tim Hortons Brier, where they went 5-6 in the round robin, missing the playoffs. The following season, at the 2015 Ontario Tankard, Balsdon and his rink lost in a tie breaker. Following the season, the team broke up.

Example Input: Question: How many total people were made Knight of the Bath? Passage 1:In 1658 Hungerford was elected Member of Parliament for Chippenham in the Third Protectorate Parliament. He was elected MP for Chippenham in 1660 for the Convention Parliament. He was made a Knight of the Bath at the coronation of King Charles II on 23 April 1661. In 1661 he was elected for Chippenham again in the Cavalier Parliament but the election was declared void. He was then re-elected in the by-election later in 1661 and also in the two elections in 1679. In January 1680 he presented a petition for the summoning of a parliament, and his avowed opposition to the court party of King Charles II led to his removal as Lord Lieutenant of his county in May 1681. He settled in Spring Gardens, Whitehall, in 1681 and was elected MP for Chippenham again in the Oxford Parliament of 1681. He was implicated in the 1683 Rye House Plot and his home at Farleigh Castle was searched for arms. He was elected MP for New Shoreham in 1685, 1688, and 1690, and for Steyning in 1695, 1698, 1700, and 1702.
 Passage 2:In March in Gatineau, Shapovalov captured his fourth ITF Futures singles title after defeating Gleb Sakharov in straight sets. Two weeks later, he won his first ATP Challenger title with a victory over Ruben Bemelmans at the 75K in Drummondville, and was the youngest Canadian to win a Challenger until Félix Auger-Aliassime's victory at the Open Sopra Steria de Lyon later in the year. The next week, he was defeated by Mirza Bašić in the final of the ATP Challenger 50K in Guadalajara, stopping his winning streak at 17 matches. At the French Open in May, his first professional Grand Slam, he was defeated in the first round of qualifying by the first seed Marius Copil in three sets. In June, Shapovalov qualified for the ATP 500 at the Queen's Club Championships, his fourth ATP main draw but his first as a qualifier. In the first round, he defeated his second top 50 player, world No. 47 Kyle Edmund, before losing to world No. 14 Tomáš Berdych. At Wimbledon in July, Shapovalov was awarded a wild card for the main draw. He was defeated by Jerzy Janowicz in the opening round. At the end of the month, he won his second ATP Challenger title, defeating compatriot Peter Polansky in the final of the 75K in Gatineau.
 Passage 3:Chris Columbus was hired by 20th Century Fox to write and direct the film in 1995. In 1997, Peter Segal was attached to a script which had been written by Columbus and Michael France. Segal later left the project in the same year. Phillip Morton worked on the script, and Sam Hamm did rewrites in 1998. The following year, Raja Gosnell signed on as director. The film was announced in August 2000 as being aimed for a July 4, 2001 release date. Gosnell decided to leave the project to film Scooby-Doo. Peyton Reed served as replacement in April 2001. Reed contemplated making the film as a period piece set in the early 1960s during the space race. He later dropped out from the film. In April 2004, Tim Story was hired to direct and principal photography began in August in Vancouver, British Columbia, Canada with re-shoots carried on until May 2005. Starring Ioan Gruffudd, Jessica Alba, Chris Evans, Michael Chiklis and Julian McMahon, the film was released on July 8, 2005.

Example Input: Question: How old was Mihailov when the Second Blakan War began? Passage 1:Pointon was born in Evesham, Worcestershire. He began his football career as an amateur with Coventry City and Redditch Town before joining Birmingham, still as an amateur, in August 1913. The club were fined £5 for playing him in the reserves before the transfer formalities had been completed. An outside left, his performances in the reserves were such that he was invited to a trial for England's amateur team, which proved unsuccessful. He made his debut in the Second Division on New Year's Day 1914 in a 2–0 defeat at Stockport County, and played three times more that season, scoring once, but left in April 1914. He played briefly for Redditch, then joined Walsall shortly before the First World War started. After the war he had a season with Nuneaton Town before returning to the Football League with Coventry City. He played twice in the Second Division for Coventry before a third spell with Redditch and finishing his career at Tamworth Castle.
 Passage 2:The main components for water-powered stamp mills – water wheels, cams, and hammers – were known in the Hellenistic era in the Eastern Mediterranean region. Ancient cams are in evidence in early water-powered automata from the third century BC. A passage in the Natural History of the Roman scholar Pliny (NH 18.23) indicates that water-driven pestles had become fairly widespread in Italy by the first century AD: "The greater part of Italy uses an unshod pestle and also wheels which water turns as it flows past, and a trip-hammer [mola]". These trip-hammers were used for the pounding and hulling of grain. Grain-pounders with pestles, as well as ordinary watermills, are also attested as late as the middle of the fifth century in a monastery founded by Romanus of Condat in the remote Jura region, indicating that the knowledge of trip hammers continued into the early Middle Ages. Apart from agricultural processing, archaeological evidence also strongly suggests the existence of trip hammers in Roman metal working. In Ickham in Kent, a large metal hammer-head with mechanical deformations was excavated in an area where several Roman water-mills and metal waste dumps have also been traced.
 Passage 3:Ivan Mihailov was born on 26 August 1896, in the village of Novo Selo (now part of Štip Municipality, North Macedonia) in the Kosovo Vilayet of the Ottoman Empire. Mihailov studied at the Bulgarian Men's High School in Thessaloniki up until the Second Balkan War when the school was closed by the new Greek administration, he later continued his studies at a Serbian school in Skopje. He was offered a scholarship by the Serbian Ministry of Education to pursue a degree at a European university but declined, later enlisting in the Bulgarian army, which had by that time occupied a significant portion of the region. After the end of World War I, Mihailov emigrated to Bulgaria, settling in Sofia. Here he began studying law at the Sofia University, at which time he was contacted by IMRO activists and offered to work as a personal secretary for IMRO's leader at that time, Todor Aleksandrov.
