Example Input: Question: What was the name of the Ottoman governor who presented Robert Rollo Gillespie with an Arabian  horse? Passage 1:He then transferred to India, traveling initially to Hamburg where, though both were in disguise and had no political principles in common, he was warned by Napper Tandy to flee to Danish territory in Altona. He continued overland through Germany, Austria, and Serbia, to the Euxine where he felt obliged to force his ship's captain at gunpoint to take him to Constantinople as agreed, rather than a corsair port for murder or slavery. He passed through Greece without recorded incidents, and took ship for Aleppo. He narrowly saved his own life, and his servant's, in the desert by curing the chief of a band of Arabs, who were planning to murder and rob him. He stayed for some time in Baghdad, where he was presented with a valuable Arabian horse by the Ottoman governor. From Basra he took ship for Bombay, then travelled overland to Madras. He was soon appointed to the command of the 19th Dragoons at Arcot, some 16 miles from Vellore.
 Passage 2:Hamilton followed his mother as a Christian Scientist, and attended Claremont Fan Court School and then Eton College. He did National Service in the Coldstream Guards from 1955 to 1958. His father had been wounded while serving with the same regiment in the Second World War. Hamilton then worked in the City of London as a gilts broker. He was a member of the London Stock Exchange from 1967 to 1980. He remained in the City for only a short period, leaving when he inherited two estates from his father's cousin. He married his wife, Corinna Dixon, in 1967, and they had four sons together. He succeeded his father as Baron Hamilton of Dalzell in 1990, inheriting land near and properties in the village of Betchworth in Surrey, and a Regency mansion.
 Passage 3:As a backbencher in Ralph Klein's Progressive Conservative caucus, Knight moved a number of government bills. The first was 2003's Electric Utilities Act, which made some changes to the government's deregulation of the province's electricity market. Much of the debate around the bill was about whether the government's deregulation had worked well to date. The bill was passed on a party line vote, with Knight's fellow Progressive Conservatives voting unanimously in favour and the opposition Liberals and New Democrats voting unanimously against. Knight also sponsored the Securities Amendment Acts, separate bills with the same name from different years, 2005 and 2006. The first of these was designed to harmonize the securities regulation with that of other provinces. It was supported by Liberals Rick Miller and Bill Bonko, who considered it a step in the right direction. New Democrats gave it a mixed reception, with Ray Martin agreeing that it did make some improvements, but with his colleague David Eggen trying to kill it on third reading, saying that what was needed was a supra-provincial securities regulator. The 2006 edition of the Securities Amendment Act implemented further harmonization, and passed with little debate. The Securities Transfer Act of the same year consolidated and harmonized the province's rules for transferring securities, and passed with all-party support.

Example Input: Question: How long did Aulus Plautius live after capturing the lands south of the River Trent? Passage 1:The general outline of the Roman conquest of Britain during the 1st century AD is recorded by historical sources; for the involvement of specific forts historians depend on archaeological excavations. This part of Britain was occupied by a tribe known as the Cornovii. In AD 46–47 the Roman Army led by governor Aulus Plautius had probably occupied the lands to the south of the River Trent. Late in 47 the new governor of Britain, Ostorius Scapula, began a campaign against the tribes of the western mountains (modern Wales). Caratacus, their leader, was defeated in battle in AD 50 and fled to the Brigantes who occupied the Pennines. Their queen, Cartimandua, came to terms with the Romans and handed Caratacus over to them. Ostorius died and was replaced by Aulus Gallus who brought the Welsh borders under control but did not move further north or west. It was at about this time that the fort at Strutt's Park was built. It probably lay not far south of the border between Roman territory and that held by the Brigantes, who were now an allied or subject kingdom.
 Passage 2:In 1854 Klindworth went to London, where he remained for fourteen years, studying, teaching and occasionally appearing in public. From London Klindworth went to Moscow in 1868, following Nikolai Rubinstein's invitation to take up the position of professor of pianoforte at the Moscow Conservatory, where he first met Pyotr Ilyich Tchaikovsky as professor of harmony. While in Russia he completed his pianoforte arrangements for Wagner's Der Ring des Nibelungen, which he had commenced during Wagner's visit to England in 1855, Beethoven's sonatas and also his critical edition of Frédéric Chopin's works. He then became conductor of the Berlin Philharmonic in 1882, in association with Joseph Joachim and Franz Wüllner, being also the conductor of the Berlin Wagner Society. At this time, he established the Klindworths Musikschule, which later became the Klindworth-Scharwenka Conservatory.
 Passage 3:Kevin Francis (born June 5, 1993) is a professional Canadian football linebacker for the Ottawa Redblacks of the Canadian Football League (CFL). After going undrafted in the 2016 NFL draft, Francis declared eligible for the 2016 CFL Supplemental Draft after informing the league that he was born in Toronto, Ontario. He was drafted by the Roughriders on May 26, 2016, who forfeited a third round selection in the 2017 CFL Draft to acquire his rights. Upon entering 2016 training camp, Francis switched to the defensive side of the ball after playing as a tight end during his college football career with the North Carolina A&T Aggies. He made his CFL debut on June 30, 2016 against the Toronto Argonauts, registering his first defensive tackle. Francis finished his rookie season leading the team in special team tackles, also being ranked 7 on the CFL rising sophomore list

Example Input: Question: What is the population of the city where Vordtriede once studied and worked as a teacher? Passage 1:After the Nazis came to power, he emigrated to Switzerland in 1933 and to the United States later. He began his studies in Zurich and worked part-time as a house teacher. Meanwhile, he wrote articles and book reviews for the Neue Zürcher Zeitung, using several pseudonyms because of prohibition of work. He earned his PhD and taught French and German Literature at various universities, including Princeton University and University of Wisconsin-Madison. During a journey to Europe, Vordtriede was surprised by the outbreak of the Second World War and interned as an Enemy alien in occupied France. By interventions, he became free months later and was allowed to go back to America. He met his mother in New York City late in 1941, who also emigrated to the USA. He received the American citizenship in 1946 and became a Guggenheim Fellow in 1957. His sister Fränze emigrated in 1947 and went to Philadelphia.
 Passage 2:Johann Diederich Gries was born into a prosperous Hamburg family, the fourth of his parents' seven recorded sons. Franz Lorenz Gries (1731-1803), his father, was a merchant and city senator. His mother Johanna also came from a mercantile background. He undertook an apprenticeship in business with a Hamburg wholesale merchant for three years between 1793 and 1795 which, he let it be known, was a miserable thing to have to do. After his elder brother Ludwig had intervened with their father on his behalf he was permitted to embark on a period of study in Law, enrolling at the University of Jena in October 1795. At Jena his naturally affability, his abundance of inoffensive humour and his exceptional talent as a piano player all combined to gain him ready access to the homes and social circles of the professors. He also acquired an extensive network of lifelong friend among his student contemporaries, such as Johann Georg Rist, Johann Friedrich Herbart, , also including a couple of years later Georg Arnold Heise, August Ludwig Hülsen and . At the home of the anatomist Justus Christian Loder he got to know Goethe and Schiller, Herder and Fichte. It was nevertheless striking that while his literary awareness and social circle developed rapidly, he approached his studies in jurisprudence with a marked absence of diligence. Early in 1797 he returned to Hamburg for a visit during which he renewed his friendship with Johann Albert Heinrich Reimarus and Friedrich Heinrich Jacobi. That summer he accompanied Caroline Schlegel and her daughter to Dresden where Schlegel was staying. That also gave him the opportunity to meet Schelling by whom he was much impressed. Around this time he also visited Freiberg where he was warmly received by . 
 Passage 3:After the political changes in 2000, Croatian cinema proved it could work in a completely free environment for the first time. As a result, at the beginning of this decade Croatian cinema flourishes again, and many critics write about "third golden era" (after the 1950s and 1960s). One of the most popular authors in the contemporary Croatian cinema is Vinko Brešan whose comedies Kako je počeo rat na mom otoku (How the War Started on My Island, 1997), and Maršal (Marshal Tito's Spirit, 1999) mix grotesque humor and political provocation. Brešan's war drama Svjedoci (Witnesses, based on a novel by Jurica Pavičić) was the first feature film from countries of former Yugoslavia which discussed the war crimes committed by "our guys", not the enemy. Film was screened in competition at the Berlin Film Festival in 2003. A Wonderful Night in Split (Ta divna splitska noć, 2004) by Arsen A. Ostojić received a nomination for the European Discovery EFA award, and Tu (Here, 2003) by Zrinko Ogresta was awarded at the Karlovy Vary Film Festival. Among other distinguished contemporary directors, internationally most recognized is Ognjen Sviličić, whose two films premiered at the Berlin Film Festival - Oprosti za kung fu (Sorry about Kung Fu, 2004) and Armin (2006). Armin was also Croatia's submission for the 2008 Academy Award, and although it didn't earn a nomination in the Best Foreign Language Film category, it did nevertheless receive the prestigious Best Foreign Film of 2007 Award given by the International Federation of Film Critics.
