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: Was Commandino older or younger than Francesco Maurolico? Passage 1:In 1787, Swedish part-time chemist Carl Axel Arrhenius found a heavy black rock near the Swedish village of Ytterby, Sweden (part of the Stockholm Archipelago). Thinking that it was an unknown mineral containing the newly discovered element tungsten, he named it ytterbite. Finnish scientist Johan Gadolin identified a new oxide or "earth" in Arrhenius' sample in 1789, and published his completed analysis in 1794; in 1797, the new oxide was named yttria. In the decades after French scientist Antoine Lavoisier developed the first modern definition of chemical elements, it was believed that earths could be reduced to their elements, meaning that the discovery of a new earth was equivalent to the discovery of the element within, which in this case would have been yttrium. Until the early 1920s, the chemical symbol "Yt" was used for the element, after which "Y" came into common use. Yttrium metal was first isolated in 1828 when Friedrich Wöhler heated anhydrous yttrium(III) chloride with potassium to form metallic yttrium and potassium chloride.
 Passage 2:Aikido was first brought to the rest of the world in 1951 by Minoru Mochizuki with a visit to France where he introduced aikido techniques to judo students. He was followed by Tadashi Abe in 1952, who came as the official Aikikai Hombu representative, remaining in France for seven years. Kenji Tomiki toured with a delegation of various martial arts through 15 continental states of the United States in 1953. Later that year, Koichi Tohei was sent by Aikikai Hombu to Hawaii for a full year, where he set up several dojo. This trip was followed by several further visits and is considered the formal introduction of aikido to the United States. The United Kingdom followed in 1955; Italy in 1964 by Hiroshi Tada; and Germany in 1965 by Katsuaki Asai. Designated "Official Delegate for Europe and Africa" by Morihei Ueshiba, Masamichi Noro arrived in France in September 1961. Seiichi Sugano was appointed to introduce aikido to Australia in 1965. Today there are aikido dojo throughout the world.
 Passage 3:Born in Urbino, he studied at Padua and at Ferrara, where he received his doctorate in medicine. He was most famous for his central role as translator of works of ancient mathematicians. In this, his sources were primarily written in Greek and secondarily in Arabic, while his translations were primarily in Latin and secondarily in Italian. He was responsible for the publication of many treatises of Archimedes. He also translated the works of Aristarchus of Samos (On the sizes and distances of the Sun and the Moon), Pappus of Alexandria (Mathematical collection), Hero of Alexandria (Pneumatics), Ptolemy of Alexandria (Planisphere and Analemma), Apollonius of Perga (Conics) and Euclid of Alexandria (Elements). Among his pupils was Guidobaldo del Monte and Bernardino Baldi. Commandino maintained a correspondence with the astronomer Francesco Maurolico. The proposition known as Commandino's theorem first appears in his work on centers of gravity.

Example Input: Question: How old was Tony Benn the year that he beat Malcolm St. Clair in the London County Council elections, in Islington East? Passage 1:A major proponent of representative government was Itagaki Taisuke, a powerful leader of Tosa forces who had resigned from his Council of State position over the Korean affair in 1873. Itagaki sought peaceful rather than rebellious means to gain a voice in government. Such movements were called The Freedom and People's Rights Movement. He started a movement aimed at establishing a constitutional monarchy and a national assembly. Itagaki and others wrote the Tosa Memorial in 1874 criticizing the unbridled power of the oligarchy and calling for the immediate establishment of representative government. Dissatisfied with the pace of reform after having rejoined the Council of State in 1875, Itagaki organized his followers and other democratic proponents into the nationwide Aikokusha (Society of Patriots) to push for representative government in 1878. In 1881, in an action for which he is best known, Itagaki helped found the Jiyūtō (Liberal Party), which favored French political doctrines. In 1882 Ōkuma Shigenobu established the Rikken Kaishintō (Constitutional Progressive Party), which called for a British-style constitutional democracy. In response, government bureaucrats, local government officials, and other conservatives established the Rikken Teiseitō (Imperial Rule Party), a pro-government party, in 1882. Numerous political demonstrations followed, some of them violent, resulting in further government political restrictions. The restrictions hindered the political parties and led to divisiveness within and among them. The Jiyūtō, which had opposed the Kaishintō, was disbanded in 1884, and Ōkuma resigned as Kaishintō president.
 Passage 2:The Sex Pistols evolved from the Strand, a London band formed in 1972 with working-class teenagers Steve Jones on vocals, Paul Cook on drums and Wally Nightingale on guitar. According to a later account by Jones, both he and Cook played on instruments they had stolen. Early line-ups of the Strand—sometimes known as the Swankers—also included Jim Mackin on organ and Stephen Hayes (and later, briefly, Del Noones) on bass. The band members regularly hung out at two clothing shops on the King's Road in Chelsea, London: John Krivine and Steph Raynor's Acme Attractions (where Don Letts worked as manager) and Malcolm McLaren and Vivienne Westwood's Too Fast to Live, Too Young to Die. McLaren's and Westwood's shop had opened in 1971 as Let It Rock, with a 1950s revival Teddy Boy theme. It had been renamed in 1972 to focus on another revival trend, the rocker look associated with Marlon Brando. As John Lydon later observed, "Malcolm and Vivienne were really a pair of shysters: they would sell anything to any trend that they could grab onto." The shop became a focal point of the punk rock scene, bringing together participants such as the future Sid Vicious, Marco Pirroni, Gene October, and Mark Stewart, among many others. Jordan, the wildly styled shop assistant, is credited with "pretty well single-handedly paving the punk look".
 Passage 3:In 1955, he stood unsuccessfully as a Conservative candidate at the London County Council elections, in Islington East. At the 1959 general election he stood as Conservative candidate in Bristol South East, but he lost to the sitting Labour Member of Parliament Tony Benn (then known as Anthony Wedgwood Benn), whose majority was nearly 6,000 votes. However, in November 1960 Benn's father died and Benn inherited his peerage as Viscount Stansgate, with an automatic seat in the House of Lords. This disqualified Benn from sitting in the House of Commons, triggering a by-election on 4 May 1961. Benn, who wished to be allowed to disclaim his peerage, defied his inability to sit in the Commons by standing at the election, and he and St Clair were the only two candidates. St Clair's campaign displayed posters near every polling station warning voters that Benn was disqualified and that any votes for him would have no effect. Benn nevertheless won the election with nearly 70% of the votes and an increased majority of over 13,000. However, an Election Court considered what to do about the result, found that Benn was disqualified from being elected and that the voters were aware of this, and awarded the seat to St. Clair as the only duly qualified candidate. (At the time, St Clair was himself Master of Sinclair – heir presumptive (1957–1968) to his second cousin Charles St Clair, 17th Lord Sinclair, one of the representative peers for Scotland in the House of Lords.)

Example Input: Question: How long had the secret project, Tube Alloys, been going on before it merged with the American Manhattan Project according to the Quebec Agreement? Passage 1:During the early part of the Second World War, Britain had a nuclear weapons project, code-named Tube Alloys, which the 1943 Quebec Agreement merged with the American Manhattan Project to create a combined American, British, and Canadian project. The British government expected that the United States would continue to share nuclear technology, which it regarded as a joint discovery, but the United States Atomic Energy Act of 1946 (McMahon Act) ended technical co-operation. Fearing a resurgence of United States isolationism, and Britain losing its great power status, the British government restarted its own development effort, which was given the cover name "High Explosive Research". The first British atomic bomb was tested in Operation Hurricane at the Monte Bello Islands in Western Australia on 3 October 1952.
 Passage 2:Romero first played on the European Tour in 1985 and was a full member from 1988 to 2005. He has 8 tournament victories and seven top twenty placings on the Order of Merit. In 2002 he became the third oldest winner on the European Tour (behind Des Smyth and Neil Coles) when he won the Scottish Open just three days before his 48th birthday. Romero came fifth on the Order of Merit for 2002. Romero turned fifty in 2004, and just a few days later he finished in a tie for second at his first senior tournament, the Senior British Open. In 2005 he won his first senior title at the European Seniors Tour's Travis Perkins Senior Masters, and he won the Wentworth Senior Masters in both 2005 and 2006. In 2006, he lost in a playoff against Loren Roberts for the Senior British Open Championship and won a playoff against Lonnie Nielsen for the JELD-WEN Tradition for his first Champions Tour win and major. He was the Champions Tour's 2006 Rookie of the Year. He won the U.S. Senior Open, his second major, at The Broadmoor in Colorado Springs in 2008.
 Passage 3:Minaj was one of the opening acts on Britney Spears' 2011 Femme Fatale Tour. She and Kesha appeared on the remix of Spears' "Till the World Ends", which peaked at number-three on the Billboard Hot 100. On August 7, 2011, Nicki experienced a "nip slip" during a live performance on Good Morning America. Minaj was criticized for wearing the low-cut shirt during her performance which led to the brief exposure of her breast on a live telecast. ABC apologized for incident. Minaj, while interviewed on ABC's Nightline show, apologized for the incident and denied that she intentionally sought to expose herself on live television as a publicity stunt. The incident attracted protest from the Parents Television Council. Despite this, Minaj continued to perform at high-profile events throughout 2011; Donatella Versace invited her to perform with Prince for the introduction of a Versace collection for H&M, and she performed "Super Bass" at the 2011 Victoria's Secret Fashion Show.
