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 is Gasaton Cros' birthplace now found? Passage 1:The Chronicon Angliae Petriburgense is a 14th-century chronicle written in Medieval Latin at Peterborough Abbey, England, covering events from 604 to 1368, although the original manuscript ends with an entry for 868, and the remainder was added in the 17th century. It survives as part of a composite manuscript volume held at the British Library with the mark Cotton Claudius A.v, in which it appears on folios 245. An edition of the Chronicon was published in 1723 by Joseph Sparke, in a collection of English histories by various writers. According to John Allen Giles, in the preface to his own edition published by the Caxton Society in 1845, the Chronicon was attributed by both Simon Patrick and Henry Wharton to John of Caleto (or "Caux"), who was an abbot of Peterborough (12501262). Giles reported a marginal note in the manuscript making a similar attribution, besides a similar note at the beginning of the manuscript stating that it belonged to Peterborough Abbey. However, Giles observed that this manuscript attribution was "comparatively modern", and regarded the chronicle's author as unknown. In Giles's view, the Chronicon is "extremely valuable both on account of the numerous facts which it contains, and for the [700 years] which it embraces."
Passage 2:Born in Berlin to the distinguished Prussian military family von Bulow, originally from Mecklenburg, he enlisted in the Prussian Army and was assigned to the 2nd Guards regiment of infantry in 1864. He saw action during the Austro-Prussian War in 1866 and gained distinction at Koniggratz. Von Bulow served through the Franco-Prussian War of 1870 as a junior officer, winning the Iron Cross Second Class. A Captain of the German General Staff in 1877, von Bulow was promoted to Colonel and assigned to the 9th Guards Regiment in 1894. In 1897, von Bulow was a major-general and became director of the Central Department in the German War Ministry. In 1900 he was promoted to lieutenant-general and in 1901 was appointed general commanding the Guards Division. He was Commander of the German III Corps from 1903 until his appointment as Inspector of the German 3rd Army in 1912.
Passage 3:Colonel Marie Augstin Gaston Cros (known as Gaston Cros) (6 October 1861 10 May 1915) was a French army officer and archaeologist. He was born in Alsace and was displaced when that territory was incorporated into the German Empire. He joined the French Army as a lieutenant and saw action in Tonkin before spending several years surveying in Tunisia, receiving the honours of membership of Vietnamese and Tunisian orders and appointment as a chevalier of the Legion of Honour. In 1901 Cros was appointed head of the French archaeological expedition to Girsu, Iraq to continue the work of Ernest de Sarzec. His work over the next five years included the tracing of the thick city wall and for his work there received a letter of commendation from Gaston Doumergue, the Minister of Fine Arts, and the award of the Golden Palms of the Ordre des Palmes Academiques. Promoted to lieutenant-colonel, Cros served in the French protectorate of Morocco from 1913, seeing action in the Zaian War.

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.

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 Fabricio 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.
