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 was the age of the oldest member (besides Stephanie) of the group representing Armenia in the Eurovision Song Contest 2015? Passage 1:Chemokine receptors are G protein-coupled receptors containing 7 transmembrane domains that are found predominantly on the surface of leukocytes, making it one of the rhodopsin-like receptors. Approximately 19 different chemokine receptors have been characterized to date, which share many common structural features; they are composed of about 350 amino acids that are divided into a short and acidic N-terminal end, seven helical transmembrane domains with three intracellular and three extracellular hydrophilic loops, and an intracellular C-terminus containing serine and threonine residues that act as phosphorylation sites during receptor regulation. The first two extracellular loops of chemokine receptors are linked together by disulfide bonding between two conserved cysteine residues. The N-terminal end of a chemokine receptor binds to chemokine(s) and is important for ligand specificity. G-proteins couple to the C-terminal end, which is important for receptor signaling following ligand binding. Although chemokine receptors share high amino acid identity in their primary sequences, they typically bind a limited number of ligands. Chemokine receptors are redundant in their function as more than one chemokine is able to bind to a single receptor.
 Passage 2:A return to the Formula Three Euroseries beckoned for van Dam, with a 2009 campaign for Kolles & Heinz Union, the new team set up by Colin Kolles and Werner Heinz. However, the partnership was not to last, as after the rounds at Lausitz, van Dam parted company with the team. In four races, his best finish was eighteenth during the season-opening race at Hockenheim. Van Dam drove in the 24-hour endurance races at the Nürburgring and at Spa, before agreeing to drive the car of PSV Eindhoven in the Superleague Formula series. He replaced Dominick Muermans in the car, with the team lying eighteenth in the overall standings. However, he returned to the Euroseries, for the Barcelona rounds, rejoining his former team SG Formula.
 Passage 3:In February 2015 she was announced as a member of the music group Genealogy (made up of singers from Armenia and the Armenian diaspora) that represented Armenia in the Eurovision Song Contest 2015. Stephanie Topalian represents the Asian continent in the formation whereas the Ethiopian Vahe Tilbian represents Africa, the American Tamar Kaprelian the American continent, the French Essaï Altounian the European continent and the Australian Mary-Jean O'Doherty Basmadjian Oceania and Inga Arshakyan Armenia. The super group sang "Face the Shadow", the Armenian entry to the 2015 Eurovision Song Contest in Vienna, Austria. She became an Armenian citizen along with the other foreign members of Genealogy on 28 April 2015 after being given Armenian passports by President Serzh Sargsyan.

Example Input: Question: Did Strings second album 2 have any hits in the United States? Passage 1:The Akademisches Kunstmuseum (English: Academic Museum of Antiquities ) was founded in 1818 and has one of the largest collections of plaster casts of ancient Greek and Roman sculptures in the world. At this time collections of plaster casts were mainly used in the instruction of students at art academies. They were first used in the instruction of university students in 1763 by Christian Gottlob Heyne at University of Göttingen. The Akademisches Kunstmuseum in Bonn was the first of its kind, as at this time collections at other universities were scattered around universities libraries. The first director was Friedrich Gottlieb Welcker, who also held a professorship of archaeology. His tenure was from 1819 until his retirement in 1854. He was succeeded by Otto Jahn and Friedrich Wilhelm Ritschl, who shared the directorship. From 1870 to 1889 Reinhard Kekulé von Stradonitz, nephew of the famous organic chemist Friedrich August Kekulé von Stradonitz, was the director. In 1872 the museum moved to a new building that was formerly used by the department of anatomy. The building was constructed from 1823 to 1830 and designed by Karl Friedrich Schinkel and Hermann Friedrich Waesemann. Other directors of the museum were Georg Loeschcke (from 1889 to 1912), Franz Winter (from 1912 to 1929), Richard Delbrück (from 1929 to 1940), Ernst Langlotz (from 1944 to 1966), Nikolaus Himmelmann (from 1969 to 1994) and Harald Mielsch (since 1994). All directors, with the exception of Friedrich Wilhelm Ritschl held a professorship of archaeology at the university.
 Passage 2:Penzias was born in Munich, Germany, the son of Justine (née Eisenreich) and Karl Penzias, who ran a leather business. His grandparents had come to Munich from Poland and were among the leaders of the Reichenbach Strasse Shul. At age six, he and his brother Gunther were among the Jewish children evacuated to Britain as part of the Kindertransport rescue operation. Some time later, his parents also fled Nazi Germany for the U.S., and the family settled in the Garment District of New York City in 1940. In 1946, Penzias became a naturalized citizen of the United States. He graduated from Brooklyn Technical High School in 1951 and after enrolling to study chemistry at the City College of New York, he changed majors and graduated 1954 with a degree in physics, ranked near the top of his class.
 Passage 3:In 1990 the band signed with EMI Records and released their debut album, Strings. Their initial experiments with synthesised sounds and rhythms were not immediately recognised, although Strings sold 20,000 copies during its first week after release. Two years later the band released their second album, 2, which included the critically acclaimed single "Sar Kiye Yeh Pahar". The song was first aired on MTV Asia, and led the band to widespread fame. After the release of 2, the quartet disbanded to focus on their studies and careers. In 2000 Maqsood and Kapadia released Duur, which revived the band's popularity, and followed it with Dhaani in 2003. This album included the single "Najane Kyun", which was part of the soundtrack for the Hollywood film Spider-Man 2. Following Junoon and Nusrat Fateh Ali Khan, Strings went to India (where they found remixes of one of their early songs playing in clubs). In 2008 Strings released their fifth album, Koi Aanay Wala Hai, with the singles "Yeh Hai Meri Kahani" and "Aakhri Alvida" (included on the soundtracks for Bollywood's Zinda and Shootout at Lokhandwala). The album was co-produced by Bollywood actor John Abraham, and was successful in Pakistan and India.

Example Input: Question: What state is the candidate Barron served as an elector from? Passage 1:From there it flows west through the Navajo Nation, turning northwest near Shiprock and its namesake monolith, crossing very briefly back into southwest Colorado (within half a mile (0.8 km) of the Four Corners quadripoint) before entering southeastern Utah. West of Bluff, Utah the river slices through the Comb Ridge and enters a series of rugged winding canyons, often over in depth. The lower of the San Juan River, in a remote portion of the Glen Canyon National Recreation Area, are flooded by Lake Powell, which is formed by Glen Canyon Dam on the Colorado River. The San Juan joins the Colorado in San Juan County, Utah at a point about to the north of Navajo Mountain and northeast of Page, Arizona.
 Passage 2:In 2002, it was proposed that a for-profit prison corporation, Cornell Corrections, build a prison on the island. To connect the island with Ketchikan, it was originally planned that the federal government spend $175 million on building a bridge to the island, and another $75 million to connect it to the power grid with an electrical intertie. The Ketchikan Borough Assembly turned the proposal down when the administration of Governor Tony Knowles also expressed its disfavor to the idea. Eventually, the corporation's prison plans led to the exposure of the wide-ranging Alaska political corruption probe, which eventually ensnared U.S. Senator Ted Stevens. The bridge idea persisted. The 2005 Highway Bill provided for $223m to build the Gravina Island Bridge between Gravina Island and nearby Ketchikan, on Revillagigedo Island. The provisions and earmarks were negotiated by Alaska's Rep. Don Young, who chaired the House Transportation Committee and were supported by the Chair of the Senate Appropriations Committee, Alaska's Senator Stevens. This bridge, nicknamed "The Bridge to Nowhere" by critics, was intended to replace the auto ferry which is currently the only connection between Ketchikan and its airport. While the federal earmark was withdrawn after meeting opposition from Oklahoma Senator Tom Coburn, though the state of Alaska received $300 million in transportation funding, the state of Alaska continued to study improvements in access to the airport, which could conceivably include improvements to the ferry service. Despite the demise of the bridge proposal, Governor Sarah Palin spent $26 million in transportation funding for the planned access road on the island that ultimately went nowhere.
 Passage 3:Before the 2012 Republican primary, Barron helped organize the "Draft Cheney 2012" movement, which was to convince the former vice president Cheney to seek the Republican presidential nomination in 2012. Early in the 2012 Republican primary process, Barron endorsed Herman Cain for the 2012 U.S. presidential election. After Cain dropped out, Barron endorsed Republican and later Libertarian Party presidential candidate Gary Johnson for the 2012 U.S. presidential election. He was a delegate to the 2012 Libertarian National Convention. In the 2012 Republican primary in the District of Columbia, Barron voted for Ron Paul. In October 2012, however, he announced he had decided to support and vote for Mitt Romney for President, even while continuing to serve as a D.C. elector for Johnson.
