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.

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.

Question: How long is the Lachlan River? Passage 1:A. Sibiryakov sailed on 28 June 1932 from the Krasny (previously Sobornoy) docks in Arkhangelsk, crossed the Kara Sea and chose a northern, unexplored way around Severnaya Zemlya to the Laptev Sea. In September, after calling at Tiksi and the mouth of the Kolyma, the propeller shaft broke and the icebreaker drifted for 11 days. However, A. Sibiryakov crossed the Chukchi Sea using improvised sails and arrived in the Bering Strait in October. A. Sibiryakov reached the Japanese port of Yokohama after 65 days, having covered more than in the Arctic seas. This was regarded as a heroic feat of Soviet polar seamen and Chief of Expedition Otto Schmidt and Captain Vladimir Voronin were received with many honors at their return to Russia.
 Passage 2:Despite that it was unusual for women to participate in archaeology at the time, in 1901, encouraged by Howard Carter, Lady William Cecil began excavations at Qubbet el-Hawa near Aswan. Her family was wintering in the area and while exploring on the west bank of the Nile had discovered what she thought might be an ancient cemetery. Carter, who in 1899 had been appointed by the Antiquities Service as one of two European Chief Inspectors and in charge of excavations in the Nile Valley south from Qus to the Sudanese border, came to see the find the following day. He arranged for permits to excavate and provided an inspector and workers to assist in the dig. She kept a diary of the details of the expedition in which multiple tombs were found, as well as wooden anthropoid coffins of the Saite Era. Though the entire necropolis was infested with termites, Tomb 21 yielded two burial boxes. The male's coffin disintegrated when it was touched, but the female's coffin remained intact and was removed. The exterior was painted in yellow and devoid of any inscription. The mummy was covered with a blue network of beading. A coarse blue glaze was used on the winged scarabs and Amenti gods depicted on the canopic jars. The sole adornment of the mummy was a one inch by half inch opaque green stone. Lady William's diary recorded that the names found in the tomb were Bao-bao, daughter of Pawebas and Shepentanefet and her brother Waher. She also reported remnants of a former burial, which may have been the tomb of Shepentanefret.
 Passage 3:He was born in Hobart, Tasmania, to shipping agent William Carmichael and Emma Willson, both Scottish-born. He was educated at Hobart and then held a variety of occupations, including coaching in Brisbane and farming on the Lachlan River, where he became involved in the Farmers and Settlers Association. Around 1893 he married Mabel Pillinger at Lake Cargelligo. In around 1900 he established a business in Sydney. In 1907 he was elected to the New South Wales Legislative Assembly as the Labor member for Leichhardt. He was appointed an honorary minister in 1910, assuming the Public Instruction and Labour and Industry portfolios in 1911. from 1912 to 1913 he was also Treasurer, returning thereafter to become Minister for Public Instruction until 1915. He enlisted in the Australian Imperial Force as a private for the First World War, serving in the 36th Battalion. He was awarded the Military Cross for action at Houplines in 1917 and was invalided home, but later returned to the frontline, attaining the rank of captain. During his return he spoke in favour of conscription, and after the war he formed the Soldiers and Citizens Party, standing as a candidate for the five-member seat of Balmain. He was defeated, and became a public accountant. His second marriage, which took place in 1934 in Sydney, was to Olive Thorngate Weston. He died at Darlinghurst in 1953.

Question: What year did the revolt take place that was masterminded by someone that Maqrizi studied theology under? Passage 1:Al-Maqrīzī was born in Fatimid Cairo and spent most of his life in Egypt, When he presents himself in his books he usually stops at the 10th forefather although he confessed to some of his close friends that he can trace his ancestry to Al-Mu‘izz li-Dīn Allāh -first Fatimid caliph in Egypt and the founder of al-Qahirah- and even to Ali ibn Abi Talib. He was trained in the Hanafite school of law. Later, he switched to the Shafi'ite school and finally to the Zahirite school. Maqrizi studied theology under one of the primary masterminds behind the Zahiri Revolt, and his vocal support and sympathy with that revolt against the Mamluks likely cost him higher administrative and clerical positions with the Mamluk regime. The name Maqrizi was an attribution to a quarter of the city of Baalbek, from where his paternal grandparents hailed. Maqrizi confessed to his contemporaries that he believed that he was related to the Fatimids through the son of al-Muizz. Ibn Hajar preserves the most memorable account: his father, as they entered the al-Hakim Mosque one day, told him "My son, you are entering the mosque of your ancestor." However, his father also instructed al-Maqrizi not to reveal this information to anyone he could not trust; Walker concludes:
 Passage 2:The concept of the morphogen has a long history in developmental biology, dating back to the work of the pioneering Drosophila (fruit fly) geneticist, Thomas Hunt Morgan, in the early 20th century. Lewis Wolpert refined the morphogen concept in the 1960s with the French flag model, which described how a morphogen could subdivide a tissue into domains of different target gene expression (corresponding to the colours of the French flag). This model was championed by the leading Drosophila biologist, Peter Lawrence. Christiane Nusslein-Volhard was the first to identify a morphogen, Bicoid, one of the transcription factors present in a gradient in the Drosophila syncitial embryo. She was awarded the 1995 Nobel Prize in Physiology and Medicine for her work explaining the morphogenic embryology of the common fruit fly. Groups led by Gary Struhl and Stephen Cohen then demonstrated that a secreted signalling protein, Decapentaplegic (the Drosophila homologue of transforming growth factor beta), acted as a morphogen during the later stages of Drosophila development.
 Passage 3:Sefer ha-Mizrachi is a supercommentary on Rashi's commentary on the Torah. It is counted in its own right as among the most important commentaries on the Torah. It was first published in Venice in 1527 after Mizrachi's death, by his son Israel. Mizrachi himself considered his commentary on Rashi the most important of his works (Responsa, Nos. 5, 78). The work shows Rashi's Talmudic and midrashic sources, and elucidates all obscure passages. It was written, partially, to defend Rashi from the strictures of the later commentators, particularly Nachmanides. A compendium by Jacob Marcaria was published under the title Kitzur Mizrachi (Trento, 1561), and later, one by Isaac ha-Kohen of Ostroh, entitled Mattenat 'Ani (Prague, 1604-9). Several commentaries have been written on Mizrachi, including Yeri'ot Shlomo by Solomon Luria (Maharshal), a supercommentary on Sefer ha-Mizrachi by Barzillai ben Baruch Jabez, and strictures on the work by Samuel Edels, (Maharsha).
