Input: Question: How old was First King Carol when the Romanian War of Independence began? Passage 1: is the best-known of Sanrio's fictional characters, created in 1974. Hello Kitty is drawn simply with a trademark red bow. Registered in 1975, Hello Kitty is now a globally known trademark. Hello Kitty has been marketed in the United States from the beginning and has held the position of U.S. children's ambassador for UNICEF since 1983. The brand rose to greater prominence during the late 1990s when several celebrities such as Mariah Carey adopted Hello Kitty as a fashion statement. New products featuring the character can be found in virtually any American department store and Hello Kitty was once featured in an advertising campaign of the retail chain Target. The character got her first Massively Multiplayer Online Game produced by Sanrio Digital and Typhoon Games entitled Hello Kitty Online which was released worldwide, including the United States, Singapore, Indonesia and the Philippines.
 Passage 2:The idea of a national cathedral first emerged following the Romanian War of Independence (1877–1878), which was mainly fought between the Russian and Ottoman Empires. The church was to symbolise the victory of Orthodox Christians over the Ottoman Muslims. The idea was shelved for lack of consensus on design, location and funding. The Unification of the Romanian Principalities in 1859, entailed a unitary organization of church structures in Moldavia and Wallachia within the Holy Synod (1872), thus the assembly of hierarchs increased to 12 members, including: the Primate Metropolitan (chairman), the Metropolitan of Moldavia and their suffragan bishops of Râmnic, Buzău, Argeș, Roman, Huși and Lower Danube (Galați) and one auxiliary vicar-bishop for every diocese. The old Metropolitan Cathedral had proved overcrowded, especially during the national holidays, such as the Proclamation of the Kingdom of Romania and the crowning of the First King Carol I (10 May 1881), when none of the over one hundred churches in Bucharest were able to receive those who would have wanted to participate in the official service. Therefore, at King Carol I's desire, Romania's Assembly of Deputies and the Senate voted in favour of the Law no.1750 on the construction of the Cathedral Church in Bucharest, promulgated by King Carol I on 5 June 1884.
 Passage 3:Born Shirley Fishman in Brooklyn, New York, she attended Abraham Lincoln High School. Her teacher, Leon Friend, arranged for guest lectures by commercial and fine artists. Shirley Fishman had the opportunity to study with three of them: Chaim Gross, Moses Soyer, and Raphael Soyer. Gross influenced her early sculptural work, which features squat figures with thick limbs. While attending Brooklyn College, where she earned her B.A. in 1944, she met Leonard Gorelick (1922–2011), a fellow student. They married in 1944 and shared an enthusiasm for art and culture. Leonard Gorelick was an orthodontist and later a collector of cylinder seals. He combined his interests by investigating the authenticity of cylinder seals through the use of dental technology, especially electronmicroscopy. Shirley Gorelick earned an M.A. at Teachers College, Columbia University in 1947. That year, she studied for several weeks with Hans Hofmann in Provincetown. For a short time in the late 1950s, she was a student of the painter Betty Holliday and, in the early 1960s, learned printmaking in the Long Island studio of Ruth Leaf.
