Example Input: Question: How many years did Darrell Van Citters work on the newer Bugs Bunny shorts? Passage 1:Ohloblyn traced his ancestry to the Novgorod-Siversky region of Left-bank Ukraine, which had formed an important part of the autonomous Ukrainian "Hetmanate" in the seventeenth and eighteenth centuries, and throughout his professional career as a historian retained a lively interest in this area and wrote frequently about it. Educated at the universities in Kiev, Odessa, and Moscow, from 1921 to 1933 he taught history at the Kiev Institute of People's Education (as Kiev University was known after the revolution), but during Joseph Stalin's purges, was dismissed from his posts, forced to recant his allegedly "bourgeois nationalist" views, and suffered repression including several months of imprisonment. In the late 1930s he returned to teaching at Kiev and Odessa universities. When the Germans occupied Kiev in the fall of 1941, Ohloblyn was appointed head of the Kiev Municipal Council, a post which he held from September 21 to October 25, and was a member of the Ukrainian National Council which tried to organize Ukrainian life under the difficult conditions of the occupation. He desperately tried to save from execution some of Jews he knew but the German commandant of Kiev informed him that "the Jewish issue belongs to exclusive jurisdiction of Germans and they will solve it at their own discretion" (, in Russian). Politics under the Nazis was not to his taste and he quickly retired from his public positions and returned to his scholarly work. In 1942 he worked as a director of Kiev Museum-Archive of Transitional Period, whose exhibition compared life under Bolsheviks and under Germans. In 1943 he moved to Lviv in western Ukraine and in 1944 to Prague. Upon the approach of the Red Army, he fled west to Bavaria. From 1946 to 1951, he taught at the Ukrainian Free University in Munich. In 1951, he moved to the United States where he was active in various Ukrainian emigre scholarly institutions such as the Ukrainian Academy of Arts and Sciences in the US and the Ukrainian Historical Association. From 1968 to 1970, he was a Visiting Professor of History at Harvard University.
 Passage 2:In 2019, Alexandrova had more success in the WTA Tour. Seeded sixth, she reached the quarterfinals of the St. Petersburg Ladies' Trophy, followed by a semifinal entry at the Hungarian Ladies Open. She entered the 3rd Round of the Premier Mandatory BNP Paribas Open in Indian Wells, after beating World No. 13 Caroline Wozniacki in three sets. She performed not satisfying on clay tournaments, except at French Open, reaching the third round of a Grand Slam tournament for the first time. In the grass court season, Alexandrova made it into the quarterfinals of the Premier Eastbourne International tournament, losing there to Karolina Pliskova. She achieved her best run in a Premier 5 tournament at the Rogers Cup, reaching the 3rd Round as qualifier. She lost to Serena Williams. After reaching the 2nd Round of the US Open and following Daria Kasatkina's 1st Round loss, Alexandrova became Russia's number one female tennis player.
 Passage 3:Beginning in 1986, Warner Bros. moved into regular television animation production. Warners' television division was established by WB Animation President Jean MacCurdy, who brought in producer Tom Ruegger and much of his staff from Hanna-Barbera Productions' A Pup Named Scooby-Doo series (1988–1991). A studio for the television unit was set up in the office tower of the Imperial Bank Building adjacent to the Sherman Oaks Galleria northwest of Los Angeles. Darrell Van Citters, who used to work at Disney, would work on the newer Bugs Bunny shorts, before leaving to form Renegade Animation in 1992. The first Warner Bros. original animated TV series Tiny Toon Adventures (1990–1995) was produced in conjunction with Amblin Entertainment, and featured young cartoon characters based upon specific Looney Tunes stars, and was a success. Later Amblin/Warner Bros. television shows, including Animaniacs (1993–1998), its spin-off Pinky and the Brain (1995–1998), and Freakazoid! (1995–1997) followed in continuing the Looney Tunes tradition of cartoon humor.

Example Input: 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.

Example Input: Question: Was Viborg Ff still operational when Burns earned a place in his first All-Star game? Passage 1:Finucane was born into a prominent republican family on the Falls Road, Belfast. He was the eldest child, with six brothers and one sister. At the start of the Troubles, his family was forced out of their home. He graduated from Trinity College, Dublin in 1973. One of his brothers, John, a Provisional Irish Republican Army (IRA) member, was killed in a car crash in the Falls Road in 1972. Another brother, Dermot, successfully contested attempts to extradite him to Northern Ireland from the Republic of Ireland for his part in the killing of a prison officer; he was one of 38 IRA prisoners who escaped from the Maze in 1983. A third brother Seamus was the fiancé of Mairead Farrell, one of the IRA trio shot dead by the Special Air Service (SAS) in Gibraltar in March 1988. Seamus was the leader of an IRA unit in west Belfast before his arrest in 1976 with Bobby Sands and seven other IRA men, during an attempt to destroy Balmoral's furniture store in south Belfast. He was sentenced to 14 years' imprisonment. Finucane's wife, Geraldine, whom he met at Trinity College, is the daughter of middle-class Protestants; together they had three children. His son John is a Sinn Féin politician who was elected as Lord Mayor of Belfast in May 2019.
 Passage 2:The Battle of Ia Drang was the first major battle between the United States Army and the People's Army of Vietnam (PAVN), also referred to as the North Vietnamese Army (NVA), and was part of the Pleiku Campaign conducted early in the Vietnam War. It comprised two main engagements, centered on two previously scouted helicopter landing zones (LZs), known as LZ X-Ray and LZ Albany. The first involved the 1st Battalion, 7th Cavalry Regiment and supporting units under the command of Lieutenant Colonel Hal Moore, and took place November 14–16, 1965 at LZ X-Ray, located at the eastern foot of the Chu Pong Massif in the central highlands of Vietnam. The second engagement involved the 2nd Battalion, 7th Cavalry Regiment plus supporting units under the command of Lieutenant Colonel Robert McDade, and took place on November 17 at LZ Albany, farther north in the Ia Drang Valley. It is notable for being the first large scale helicopter air assault and also the first use of Boeing B-52 Stratofortress strategic bombers in a tactical support role. Surrounded and under heavy fire from a numerically superior force, the American forces at LZ X-ray were able to hold off and drive back the North Vietnamese forces over three days of battle, largely through the support of both air power and heavy artillery bombardment, which the North Vietnamese lacked. LZ X-ray was considered an American tactical victory, as the Americans were able to exact an almost 10:1 kill ratio. At LZ Albany, the American forces were ambushed in close quarters. They were unable to use air and artillery support due to the close engagement of the North Vietnamese, the American forces were badly defeated, suffering an over-50% casualty rate before being extricated from the battle. Both sides, therefore, were able to claim victory in the battle.
 Passage 3:In 1995, the MLS began an expansion plan to add new teams to the league. In the 1996 MLS Inaugural Allocations, the MLS assigned Burns to the New England Revolution. In August 1995, the MLS loaned out Burns to Danish club Viborg FF. The Revolution retained his rights and Burns returned to play for the Revolution in 1996. In 1998, Burns earned a place in the MLS All-Star game. In the 1999 off-season, he made several attempts to move back to a European club, trying out with clubs such as Utrecht, Bolton and Hearts. None of the clubs expressed interest in him and Burns returned to the Revolution. In June 2000, the Revolution traded Burns, Dan Calichman and a first round draft pick to the San Jose Earthquakes in exchange for Mauricio Wright. Burns finished the 2000 season with the Earthquakes. However, he did not remain with the team and he was traded in March 2001 to the Kansas City Wizards in return for conditional picks in the 2002 MLS SuperDraft. Burns played two seasons with the Wizards, 2001 and 2002. In 2002, he was chosen to play in the 2002 MLS All-Star Game. At the end of the 2002 season, Burns announced his retirement from professional football.
