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: Who was the first president of the organization Alfred served as both secretary and president? Passage 1:On 1 September 2012, Affane made his debut for the club against Willem II where he came on as a substitute in the second half and provided the assist for Krisztián Németh's goal and also won the Man of the match. Roda JC went on to win the match 3–0 and this was their first league win in the 2012–13 season. He started his first game for Roda in their next fixture on 16 September 2012 away to AZ Alkmaar, where the game ended in a 4–0 loss. On 25 September 2012, Affane made his KNVB Cup debut for Roda, where they lost 1–0 at home to PEC Zwolle in the extra time. On 30 September 2012, he scored his first goal for Roda in an Eredivisie match where they lost 3–2 to Groningen. He came in as a substitute in the 71st minute and awarded the team with a hard shot from 22 meters and scored the equalizer from a pass by Abel Tamata, 2–2 in the 78th minute. On 20 October 2012, Amin again came in to play as a substitute in the second half of the match where they were drawn 1–1 to FC Twente and assisted the only goal by them, which was scored by Guus Hupperts, while Affane's low cross was missed by Twente goalkeeper Nikolay Mihaylov. On 11 November 2012, Affane set up their two goals which were scored by Senharib Malki and Bart Biemans, both from corners in a 5–2 away loss against Feyenoord at De Kuip. Amin Affane returned to Chelsea after seeing the loan spell at Eredivisie side Roda JC cut short. He initially saw plenty of first-team football at Roda, but fell out of favour in February and has subsequently been deemed surplus to requirements.
 Passage 2:Alfred Stillé (October 30, 1813 – September 24, 1900) was an American physician. Born in Philadelphia, he studied classics at Yale, but was expelled for participating in the Conic Sections Rebellion. He then transferred to the University of Pennsylvania in the same year, where he received an A.B. degree in 1832. He went on to get an A.M. from the University of Pennsylvania in 1835 and in 1836 an M.D. from the school's department of medicine. He settled to practice in his native city, but spent parts of 1841 and 1851 in Paris and Vienna. From 1854 to 1859 he was professor of medicine at the Pennsylvania Medical College and from 1864 to 1884 at the University of Pennsylvania, later becoming its Chair. Stillé was one of the first in America to distinguish between typhus and typhoid fever. His observations in this connection he made during a typhus epidemic in Philadelphia in 1836 and reported in 1838. He acquired a great reputation as a practitioner, teacher, and writer, and was the first secretary, and in 1871–72 the president, of the American Medical Association. However, as evidenced by his later writings, he was also known for refusing to accept the germ theory or laboratory medicine.
 Passage 3:Eritrea returned to the 2009 CECAFA Cup in Nairobi. A young squad was assembled with just 12 days' training. In Group B, they gained a surprise draw with Zimbabwe, lost narrowly to Rwanda, and beat Somalia 3–1. They were easily beaten 4–0 in the quarter-finals by Tanzania. Twelve squad members failed to report for the return flight, and sought the assistance of the Refugee Consortium of Kenya. They were believed to be in hiding in Eastleigh, an eastern suburb of Nairobi home to many immigrants. Nicholas Musonye, the secretary-general of CECAFA, feared that the government might react by refusing to let the team travel abroad in future. The twelve players were later granted interim asylum by the United Nations High Commissioner for Refugees in Kenya. Eleven of these players have since travelled to Adelaide in Australia with two of them, Samuel Ghebrehiwet and Ambes Sium, signing for Gold Coast United in the A-League in August 2011.

Example Input: Question: Who owned the promotion that Leon made several appearances in during 2006? Passage 1:In an open letter to the President, the Congress, and the American people, eighty economists, including Nobel Laureate Vernon L. Smith, stated that the FairTax would boost the United States economy. According to the National Bureau of Economic Research and Americans For Fair Taxation, GDP would increase almost 10.5% in the year after the FairTax goes into effect. Real investments could increase by as much as 76% initially and remain 15% above present levels. In addition, the incentive to work would increase by as much as 20%, the economy's capital stock would increase by 42%, labor supply by 4%, output by 12%, and real wage rate by 8%. A study in 2007 by the Beacon Hill Institute of Suffolk University stated that within five years real GDP would increase 10.7% over the current system, domestic investment by 86.3%, capital stock by 9.3%, employment by 9.9%, real wages by 10.2%, and consumption by 1.8%. Laurence Kotlikoff of Boston University finds that the shift to the FairTax would raise marginal labor productivity and real wages over the course of the century by 18.9% and long-run output by 10.6%. Further, studies of the FairTax at Boston University and Rice University suggests the FairTax will bring long-term interest rates down by as much as one third. As falling tax compliance costs lower production costs, exports would increase by 26% initially and remain more than 13% above present levels. According to Professor Dale Jorgenson of Harvard University’s Economics Department, revenues to Social Security and Medicare would double as the size of the economy doubles within 15 years after passage of the FairTax. Wall Street Journal columnist James Taranto states the FairTax is unsuited to take advantage of supply-side effects and would create a powerful disincentive to spend money.
 Passage 2:After leaving AtoZ, Takase began wrestling under a mask and adopted the new ring name Toujyuki Leon. Her first appearance under the new character, took place on February 11, 2005, when she was defeated by Akino at a JDStar event. On February 20, Toujyuki Leon made her debut for JWP Joshi Puroresu, losing to Tsubasa Kuragaki. She returned to the promotion on April 24, when she teamed with Kaori Yoneyama to defeat Eco and Kazuki to become the number one contenders to the JWP Tag Team Championship. On May 15, Toujyuki Leon and Yoneyama defeated Akino and Tsubasa Kuragaki to become the new JWP Tag Team Champions. For most of 2005, Toujyuki Leon for the M's Style promotion, where she defeated Ayako Hamada on April 24 to win the Tournament of Style, while also making it to the finals of a one night tag team tournament on August 7, teaming with noki-A. On December 4, Toujyuki Leon defeated Hikaru in the finals of a seven-woman tournament to win the Next Shining Generation (NSG) Championship, an independent title with no official home promotion. She would hold the title for four months, before losing it to Hikaru on April 2, 2006. After a fifteen-month reign, Toujyuki Leon and Kaori Yoneyama lost the JWP Tag Team Championship to Ran Yu-Yu and Toshie Uematsu on August 6, 2006. During 2006, Toujyuki Leon also made several appearances for the Ibuki and Oz Academy promotions.
