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.

[EX Q]: 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.

[EX Q]: Question: How old was the king when he conferred a title on Viscount Netterville? Passage 1:Unclassified discussions open to the public at UNHQ occur once or twice a year and an RSVP is regularly announced on Twitter. An event held on December 10, 2015 looked at The Economic Cost of LGBT Exclusion and offered fiscal effects from exclusionary practices from the World Bank who estimated it to be 5% of GDP and included the companion video released by the UN's Free & Equal campaign. International concerns of the UN such as extreme hunger or clean water supplies could be remedied if this 5% of GDP was reallocated. At that meeting, the UNDP announced the launch of their LGBTI Inclusions Index, a global collection of data which they hope will help sway minds and move countries toward a brighter future for LGBTQ+ citizens. Another topic speaker on that day was the CEO of Out & Equal who recounted her 20-year efforts working with Fortune 500 and 1000 companies watching them move from 5% inclusion in 1995 to 90% inclusion by 2015. On September 20, 2017, the Group held an event entitled Ending Violence and Discrimination against LGBTI Persons. This included firsthand reports of Human Rights violations. For May 17, 2018 on International Day Against Homophobia, Transphobia and Biphobia, the UN LGBTI Core Group Special Event Celebrating our Allies opened with remarks by the UK Ambassador.
 Passage 2:Viscount Netterville was a title in the Peerage of Ireland. It was created in 1622 for Nicholas Netterville, 1st Viscount Netterville (1581–1654), son of John Netterville of Dowth, County Meath. He was a favorite of King James I of England who in 1622 conferred the title on him "in consideration of his many good qualities". He suffered considerable financial hardship during the English Civil War when the English Parliament, after the failure of the Royalist cause, sequestered his estates, along with those of his eldest son, John, the 2nd Viscount. During the Irish Rebellion of 1641 John, who was adhered to Roman Catholicism, was accused of favouring the rebels, and it does not seem that either side to the conflict fully trusted him. Possibly for this reason his son Nicholas, the 3rd Viscount, had some difficulty after the Restoration of Charles II in recovering the family estates. Because of Nicholas's loyalty to James II the estates were again forfeited after the Glorious Revolution of 1688, but were later restored to his son John, the 4th Viscount. 
 Passage 3:Kretzschmaria deusta, commonly known as brittle cinder, is a fungus and plant pathogen found in temperate regions of the Northern Hemisphere. It is common on a wide range of broadleaved trees including beech (Fagus), oak (Quercus), lime (Tilia), Horse Chestnut and maple (Acer). It also causes serious damage in the base of rubber, tea, coffee and palms. It causes a soft rot, initially and preferentially degrading cellulose and ultimately breaking down both cellulose and lignin, and colonises the lower stem and/or roots of living trees through injuries or by root contact with infected trees. It can result in sudden breakage in otherwise apparently healthy trees. The fungus continues to decay wood after the host tree has died, making K. deusta a facultative parasite. The resulting brittle fracture can exhibit a ceramic-like fracture surface. Black zone lines can often be seen in cross-sections of wood infected with K. deusta.

[EX Q]: Question: Is Liverpool the capital of a country? Passage 1:Louisiana French (, Louisiana Creole: françé la lwizyàn) refers to the complex of dialects and varieties of the French language spoken traditionally in colonial Lower Louisiana. As of today Louisiana French is primarily used in the U.S. state of Louisiana, specifically in the southern parishes, though substantial minorities exist in southeast Texas as well. Over the centuries, the language has incorporated some words of African, Spanish, Native American and English origin, sometimes giving it linguistic features found only in Louisiana, Louisiana French differs to varying extents from French dialects spoken in other regions, but Louisiana French is mutually intelligible with all other dialects and particularly with those of Missouri, New England, Canada and northwestern France. Many famous books, such as Les Cenelles, a poetry anthology compiled by a group of gens de couleur libres, and Pouponne et Balthazar, a novel written by French Creole Sidonie de la Houssaye, are in standard French. It is a misconception that no one in Louisiana spoke or wrote Standard French. Figures from the United States Census record that roughly 3.5% of Louisianans over the age of 5 report speaking French or a French-based creole at home. Distribution of these speakers is uneven, however, with the majority residing in the south-central region known as Acadiana. Some of the Acadiana parishes register francophone populations of 10% or more of the total, with a select few (such as Vermilion, Evangeline and St. Martin Parishes) exceeding 15%.
 Passage 2:Baptised in Liverpool 23 September 1833 in the heart of the city's slums he was the son of a brushmaker, also called William Hodgkins. His mother had been Jane Grocott or Groocock and his sister Jane was born in 1835. William Mathew went to school at Staveley, Derbyshire and his exercise book in penmanship survives, prefiguring his adult career as a law clerk and lawyer and his lifelong interest in graphics. By 1852 his father was in business in Birmingham but William Mathew was a law clerk in London. He lived in Holborn, worked for Waterlow and Sons, famous printers of stamps and bank notes, and for the Patent Office. By 1855 he was in Paris where he assisted in 'literary work' at Versailles, perhaps copying correspondence or graphic works. Back in London about 1857 he studied Turner's paintings and other artists, at Hampton Court and the National Gallery. In 1859 he worked at the National Portrait Gallery in London.
 Passage 3:The Bogd Khanate of Mongolia was the government of Mongolia (Outer Mongolia) between 1911 and 1919 and again from 1921 to 1924. By the spring of 1911, some prominent Mongolian nobles including Prince Tögs-Ochiryn Namnansüren persuaded the Jebstundamba Khutukhtu to convene a meeting of nobles and ecclesiastical officials to discuss independence from the Manchu-led Qing China. On November 30, 1911 the Mongols established the Temporary Government of Khalkha. On December 29, 1911 the Mongols declared their independence from the collapsing Qing Empire following the Xinhai Revolution. They installed as theocratic sovereign the 8th Bogd Gegeen, highest authority of Tibetan Buddhism in Mongolia, who took the title Bogd Khaan or "Holy Ruler". The Bogd Khaan was last khagan of Mongolia. This ushered in the period of "Theocratic Mongolia", also known as the Bogd Khanate.
