Question: What was the population of Muirhouse in 1955? Passage 1:Because his father - Sergey Matveyev - was a notable diplomat, Artamon Matveyev was brought up at the royal court since the age of thirteen, where he would become close friends with Alexius I. Matveyev started his career as a government official, who worked in Ukraine and took part in some of Russia's wars with Poland. He was a member of the Russian delegation at the conclusion of the Treaty of Pereyaslav in 1654 and Russian diplomatic mission to Poland in 1656-1657. As the head of the Streltsy Department, Matveyev participated in suppression of the Copper Riot in 1662. Seven years later, he was put in charge of the Malorossiysky Prikaz, i.e. Ministry of the Ukrainian Affairs, and in 1671 - head of the Posolsky Prikaz (foreign ministry) and other ministries. Matveyev was known to have considered unification of Ukraine and Russia as the most important issue of the Russian foreign policy. He once said that it was even possible to temporarily forget about the struggle with the Swedes for the Baltic Sea for the sake of unification with Ukraine. In 1672, Matveyev managed to secure Kiev for Russia during the talks with Poland.
 Passage 2:Irvine Welsh was born in Leith, the port area of the Scottish capital Edinburgh. He states that he was born in 1958, though, according to the Glasgow police, his birth record is dated around 1951. When he was four, his family moved to Muirhouse, in Edinburgh, where they stayed in local housing schemes. His mother worked as a waitress. His father was a dock worker in Leith until bad health forced him to quit, after which he became a carpet salesman; he died when Welsh was 25. Welsh left Ainslie Park High School when he was 16 and then completed a City and Guilds course in electrical engineering. He became an apprentice TV repairman until an electric shock persuaded him to move on to a series of other jobs. He left Edinburgh for the London punk scene in 1978, where he played guitar and sang in The Pubic Lice and Stairway 13, the latter a reference to the Ibrox disaster. A series of arrests for petty crimes and finally a suspended sentence for trashing a North London community centre inspired Welsh to correct his ways. He worked for Hackney London Borough Council in London and studied computing with the support of the Manpower Services Commission.
 Passage 3:The third son of Edmond Prideaux, he was born at Padstow, Cornwall, on 3 May 1648. His mother was a daughter of John Moyle. After education at Liskeard grammar school and Bodmin grammar school, he went to Westminster School under Richard Busby, recommended by his uncle William Morice. On 11 December 1668 he matriculated at Christ Church, Oxford, where he had obtained a studentship. He graduated B.A. 22 June 1672, M.A. 29 April 1675, B.D. 15 November 1682, D.D. 8 June 1686. In January 1674, Prideaux recorded in his letters a visit to his home of William Levett; with Levett came Lord Cornbury, son of the Earl of Clarendon, Levett's principal patron. In other letters, Prideaux mentioned alliances with Levett in ongoing church political maneuverings. At the university he was known for scholarship; John Fell employed him in 1672 on an edition of Florus. He also worked on Edmund Chilmead's edition of the chronicle of John Malalas.

Question: How many seats are required for a majority in the parliament that the first informal Parliamentary group for HIV/AIDS was formed in? Passage 1:An avid sportsman, Pierre Lorillard and his brother, George Lyndes Lorillard, were both major figures in Thoroughbred horse racing. In 1874, Pierre's horse, Saxon, won the Belmont Stakes. Although his horse Parole finished fourth in the 1876 Kentucky Derby, it went on to race with considerable success both in the United States and in Europe. In the 19th century, shipping horses from New York to Louisville, Kentucky was a major undertaking and as the Preakness Stakes and the Belmont Stakes were both held in the New York City area in the period, neither of the Lorillard brothers entered horses again in the Kentucky Derby. Pierre Lorillard established Rancocas Stable, named for the New Jersey town where he owned a country house. He spent time in Paris and in England where, in 1881, his horse Iroquois became the first American-owned and bred horse to win a European classic race. Ridden by the champion English jockey Fred Archer, Iroquois won The Derby and then went on to capture the St. Leger Stakes as well. Lorillard had other successes in England, notably with the horse named for the actor David Garrick, which won the 1901 Chester Cup ridden by American jockey, Danny Maher.
 Passage 2:The 2008 Olympics U.S. Men's Basketball Team represented the United States of America at the 2008 Summer Olympics in Beijing, China. They qualified for the Olympics by winning the FIBA American Championships 2007 held in Las Vegas, Nevada. The team was nicknamed the "Redeem Team", a play on an alternative name for the legendary 1992 squad that was called the "Dream Team", and a reference to the fact that the United States came away with disappointing Bronze Medals during the 2004 Summer Olympics and the 2006 FIBA World Championship. Kobe Bryant was named the team captain and Mike Krzyzewski was named the head coach of the 2008 team. LeBron James, called the "voice of the U.S. team" by Time, stated: "It's the gold, or it's failure." An ESPN program, Road to Redemption, followed the team's preparations.
 Passage 3:The project „Acceptance and Participation of People Living with HIV in Serbian Society” contributed to increasing the role of PLHIV, reinforcing their position in the society, organizing self-help groups and coordination of their activities, their integration in National association of PLHIV and promoting the fight against discrimination, all that for contributing to making sustainable mechanisms that would successfully protect human rights and allow them full access to public services and necessary therapy. PLHIV participation and lobbying for the overall improvement of their rights, establishment of National AIDS experts group which focuses on legislation concerning the matter and the establishment of the first informal Parliamentary group for HIV/AIDS in Serbian Parliament, helped PLHIV to speak freely and openly about their status, making their overall status and approach to prevention and therapy better. Further activities that have been planned include support to PLHIV Union and helping them to connect to relevant European networks, lobbying for permanent parliamentary group and continuing work of the Experts Group on urgent questions such are: the shortage of continuous control and therapy for PLHIV in prisons, the lack of CD4 and PCR tests or the change of legislation that criminalizes HIV transmission. This project was financed by the European Commission and implemented in cooperation with Hivos (Stichting Humanistisch Instituut voor Ontwikkelingssamenwerking – Humanist Institute for Co-operation with Developing Countries) from Netherlands during the period from 2008 until April 2011.

Question: How long did Yoshika command Un'yō? Passage 1:Cecil's success in 2011 was partly due to his training of the Khalid Abdullah-owned Frankel. In the 2010 season Frankel won the Royal Lodge Stakes and Group One Dewhurst Stakes. The following year he continued unbeaten, winning the Greenham Stakes, the 2,000 Guineas, the St. James's Palace Stakes at Royal Ascot, the Sussex Stakes and the Queen Elizabeth II Stakes. His six length victory in the 2,000 Guineas was described as "one of the greatest displays on a British racecourse". After his win in the Sussex Stakes Cecil himself described Frankel as "the best horse I've ever seen". Timeform and the International Federation of Horseracing Authorities rated him the best horse in the world. In his four-year-old season Frankel won the Group One Lockinge Stakes at Newbury before an eleven length victory in the Queen Anne Stakes at Royal Ascot, described in one national newspaper as "possibly the best single performance by any horse, on any track, since three Arabian stallions were imported into Britain to found the thoroughbred breed in the early years of the 18th century". Timeform raised their rating to 147, making Frankel the highest rated horse in their history. He won a second Sussex Stakes, at odds of 1–20, and then stepped up in distance to win by seven lengths the Juddmonte International Stakes at York over 10 furlongs. In October 2012 Frankel won the Champion Stakes at Ascot to finish his career unbeaten. "He's the best I've ever had, the best I've ever seen", Cecil told the BBC after the race, "I'd be very surprised if there's ever been a better."
 Passage 2:Williams was born in New York City to Dr. Richard Derby and Ethel Carow Roosevelt. Edith Roosevelt Derby was the second child of Dr. and Mrs. Derby and the eldest daughter. President Theodore Roosevelt was her grandfather. She was named for her grandmother Edith Roosevelt. She was actively involved in Republican politics and addressed the 1960 Republican National Convention, seconding the nomination of Richard Nixon. Later she founded the Vashon Island Health Center. For forty years, she was the Republican Committeewoman for the state of Washington. In 1975 Williams was named to the Board of Trustees for the University of Washington where she served until 1981. Mrs. Williams served on the Board of Trustees for the Theodore Roosevelt Association where she received the Rose Award in 2004 for her many years of service and dedication to the organization. Williams was also recognised for her work in behalf of conservation and promoting a healthier environment by reducing pollution.
 Passage 3:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.
