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 the group that built the improved Devils Canyon Road formed before or after the Washington State Department of Transportation? Passage 1:When Bundgaard arrived in Copenhagen, he undertook a variety of odd jobs until his artistic talents were discovered by Emil Blichfeldt who encouraged him to attend the Technical School in 1884 and later the Danish Academy. It was there that he was introduced to French Naturalism by Stephan Sinding, giving his works with a rather dramatic touch. A stay in Paris also provided him with inspiration from Jules Dalou, Alexandre Falguière and Auguste Rodin. In addition, his father's interest in mythology and folk tales reinforced his imaginative approach which can be seen in his robust, Naturalistic works, often made of granite. His interest in ecclesiastical art from the Middle Ages is also apparent. Bundgaard undertook several major decorative projects including sculptures for the recently built Copenhagen City Hall (1894–99) and for Christiansborg Palace (1907–28) where his four majestic figures stand over the entrance to the parliamentary chamber. Bundgaard's works often exhibit a mythological, nationalistic slant as can be seen in two of his masterpieces, the Gefion Fountain (1908) on Copenhagen's waterfront and the Cimbrian Bull (1937) in Aalborg. He also completed a number of monuments in commemoration of the volunteers from 1848 and 1864 as well as the Reunification Monument in Randers. Many of Bundgaard's original plaster models can be seen in the Thingbæk Kalkminer Museum, a former mine near the Rebild National Park.
 Passage 2:Adams was active in rioting at this time and later became involved in the republican movement. In August 1971, internment was reintroduced to Northern Ireland under the Special Powers Act 1922. Adams was interned in March 1972, on , but on the Provisional IRA's insistence was released in June to take part in secret, but abortive talks in London. The IRA negotiated a short-lived truce with the British government and an IRA delegation met with British Home Secretary William Whitelaw at Cheyne Walk in Chelsea. The delegation included Adams, Martin McGuinness, Sean Mac Stiofain (IRA Chief of Staff), Daithi O'Conaill, Seamus Twomey, Ivor Bell and Dublin solicitor Myles Shevlin. Adams was re-arrested in July 1973 and interned at the Long Kesh internment camp. After taking part in an IRA-organised escape attempt, he was sentenced to a period of imprisonment. During this time, he wrote articles in the paper An Phoblacht under the by-line "Brownie", where he criticised the strategy and policy of Sinn Féin president Ruairí Ó Brádaigh and IRA Belfast OC Billy McKee. He was also highly critical of a decision taken by McKee to assassinate members of the rival Official IRA, who had been on ceasefire since 1972. 
 Passage 3:Devils Canyon was originally home to the Portland–Spokane line of the Spokane, Portland and Seattle Railway, completed in 1908 with a small tunnel near the north bank of the Snake River. The United States Army Corps of Engineers built an improved Devils Canyon Road to connect Kahlotus to a grain facility owned by the newly established Port of Kahlotus in 1961. The Lower Monumental Dam on the Snake River was completed in February 1969 and opened in May of the same year at the south end of Devils Canyon. The rail line fell into disuse by 1987 and the right-of-way was acquired by the Washington State Park System in 1991 to become the Columbia Plateau Trail. The road was designated as State Route 263 (SR 263) in 1991 and signed into law on April 1, 1992 to serve the Port of Kahlotus, now the Port of Windust, and connect to the existing SR 260 in Kahlotus. No major revisions have occurred since the signing of the highway in 1961, however a landslide in July 2012 closed the highway for two days as Washington State Department of Transportation crews cleared up to of debris and later repairing damaged asphalt.

Example Input: Question: How long after the Battle of Princeton did the war during which Fort Mercer was built end? Passage 1:The Calgary Flames selected him in the eighth round, 182nd overall at the 1981 NHL Entry Draft, and he began his professional career in 1983–84 with a 30-point season for the Colorado Flames of the Central Hockey League (CHL). He then spent the majority of three seasons in the American Hockey League (AHL) with the Moncton Golden Flames. He was named to the AHL second All-Star Team in 1984–85, and served as captain of the Golden Flames in 1985–86. DeGray appeared in one NHL game that season, making his NHL debut with Calgary on March 6, 1986, against the New York Rangers. He played a part-time role in Calgary in 1986–87; in 27 games with the Flames, DeGray scored six goals and seven assists.
 Passage 2:Mušicki was stationed in Slavonski Brod at the time of the Axis invasion of Yugoslavia in April 1941 and served as the Royal Yugoslav Army commander responsible for the railroad between Belgrade and Zagreb in the rank of colonel. He demonstrated his support for the Germans by helping their forces during the invasion. Yugoslavia was quickly conquered by the Axis powers and Mušicki remained in Slavonski Brod for several months after the conquest. He attempted to join the Ustaše Militia there, but was rejected. He went to Belgrade in mid-August, where he was received by Zbor leader Dimitrije Ljotić. On 6 October, Milan Nedić, the Prime Minister of the Axis-installed puppet Government of National Salvation, appointed Mušicki to lead the Serbian Volunteer Command (, SDK). Mušicki was involved in executing Serb civilians in the town of Čačak in December 1941. He and Milan Aćimović contacted Chetnik leader Draža Mihailović on 5 December, possibly in an effort to warn him in advance of the assault the Germans had planned, codenamed Operation Mihailovic. This action prompted the Germans to question Mušicki's loyalty. He was removed from command at the end of 1941 and imprisoned by the Germans, but was later freed at Nedić's intervention.
 Passage 3:Fort Mercer was a fort on the Delaware River in New Jersey constructed by the Continental Army during the American Revolutionary War. Built by Polish engineer Thaddeus Kosciuszko under the command of George Washington, Fort Mercer was built in 1777 to block the approach to Philadelphia, Pennsylvania in concert with Fort Mifflin on the Pennsylvania side. Fort Mercer was located in an area called Red Bank, in what is now the borough of National Park, Gloucester County, New Jersey. The fort was named in honor of Brigadier General Hugh Mercer who had died earlier that year at the Battle of Princeton. The fort's site is now part of Red Bank Battlefield Historical Park, which includes a monument and museum. Several cannons attributed to British warships lost supporting the attack on the fort, and others found buried at the fort itself, are in the park.

Example Input: Question: How old was Robert Nairac when Jones was promoted to lieutenant?  Passage 1:He has been a professor at Princeton since 1975, following a leave from his professorship at MIT. Lieb has been awarded several prizes in mathematics and physics, including the 1978 Heineman Prize for Mathematical Physics of the American Physical Society and the American Institute of Physics (1978), the Max Planck Medal of the German Physical Society (1992), the Boltzmann medal of the International Union of Pure and Applied Physics (1998), the Schock Prize (2001), and the Henri Poincaré Prize of the International Association of Mathematical Physics (2003). Lieb is a member of the U.S. National Academy of Sciences and has twice served (1982–1984 and 1997–1999) as the President of the International Association of Mathematical Physics. Lieb was awarded the Austrian Decoration for Science and Art in 2002. In 2012 he became a fellow of the American Mathematical Society and in 2013 a Foreign Member of the Royal Society.
 Passage 2:He was promoted to lieutenant on 23 January 1962, captain on 23 July 1966, and major on 31 December 1972, At this time he was brigade major at HQ 3rd Infantry Brigade in Northern Ireland. As such he was responsible for the efforts to find Captain Robert Nairac who had been abducted by the Provisional IRA. Nairac and Jones had become friends and would sometimes go to the Jones household for supper. After a four-day search, the Garda Síochána confirmed that Nairac had been shot and killed in the Republic of Ireland after being smuggled over the border. On 13 December 1977 he was appointed a Member of the Order of the British Empire (MBE) for his services in Northern Ireland that year. On 30 June 1979 he was promoted lieutenant colonel, and on 1 December 1979, he was transferred to the Parachute Regiment. In the 1981 New Year Honours he was appointed an Officer of the Order of the British Empire (OBE).
 Passage 3:In 1919, after the end of the war, he started his writing career. He wrote a polemical work entitled "The Knight, death and the devil: the heroic idea", a reworking of the tradition of German Pagan-Nationalist Romanticism into a form of "biological nationalism". Heinrich Himmler was very impressed by this book. In 1922 Günther studied at the University of Vienna while working in a museum in Dresden. In 1923 he moved to Scandinavia to live with his second wife, who was Norwegian. He received scientific awards from the University of Uppsala and the Swedish Institute for Race Biology, headed by Herman Lundborg. In Norway he met Vidkun Quisling. In May 1930 he was appointed to the University of Jena by Wilhelm Frick who had become the first NSDAP minister in a state government when he was appointed minister of education in the right-wing coalition government formed in Thuringen following an election in December 1929. In 1935 he became a professor at the University of Berlin, teaching race science, human biology and rural ethnography. From 1940 to 1945 he was professor at Albert Ludwigs University.
