Example Input: Question: Where did Dudow work with Leopold Jessner? Passage 1:Dudow was born in Zaribrod, Bulgaria (today Dimitrovgrad, Serbia). In 1922, he emigrated to Berlin with the intention of becoming an architect. He gave up this plan and began studying theatre in 1923, first under Emmanuel Reicher, and then, from 1925 to 1926, as a theatre studies student under Max Herrmann at the university. He worked with Leopold Jessner and Jurgen Fehling, served as a chorus member under Erwin Piscator, and was a director's assistant to Fritz Lang on the production of Metropolis. During this time, Dudow also ran a bookstore with his wife and worked as a foreign correspondent for a Bulgarian newspaper. In 1929, he visited the Soviet Union, where he met Vladimir Mayakovsky and Sergei Eisenstein in Moscow and eventually, Bertolt Brecht. After his return from the USSR, Dudow directed Brecht's theatrical piece, The Decision (Die Massnahme), and began his film directing career. He was commissioned by the left-wing, Soviet-German production company Prometheus-Film to direct a short film, Wie der Berliner Arbeiter wohnt (1929), as part of the documentary series Wie lebt der Berliner Arbeiter? Dudow's first feature, Kuhle Wampe (To Whom Does the World Belong?, 1932) was a collaboration with Brecht (who provided the script and helped finance the project), Hanns Eisler, and Ernst Ottwalt. It was banned because it was perceived as being politically subversive.
Passage 2:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 21 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17points above Carlisle United, the only side to be relegated out of The Football League.
Passage 3:Jones was selected by the Dallas Cowboys in the first round (24th overall) of the 1992 NFL Draft, becoming the first player from East Carolina University to be drafted that high. The team moved Ken Norton Jr. to outside linebacker, allowing him to become the second rookie (Eugene Lockhart) in Cowboys history to start at middle linebacker, and the second rookie (Lee Roy Jordan) linebacker in franchise history to start in a season-opener. He helped the Cowboys establish the top defense in the league in 1992, was named NFC rookie of the year and was selected to the NFL All-rookie team. He started 13 out of 15 games, posting 108 tackles (second on the team), one sack, 2 tackles for loss, 4 quarterback pressures, one pass defensed and one fumble recovery. He had 16 tackles against both the Philadelphia Eagles and Kansas City Chiefs.

Example Input: Question: What country is Gasaton Cros' birthplace now found? Passage 1:The Chronicon Angliae Petriburgense is a 14th-century chronicle written in Medieval Latin at Peterborough Abbey, England, covering events from 604 to 1368, although the original manuscript ends with an entry for 868, and the remainder was added in the 17th century. It survives as part of a composite manuscript volume held at the British Library with the mark Cotton Claudius A.v, in which it appears on folios 245. An edition of the Chronicon was published in 1723 by Joseph Sparke, in a collection of English histories by various writers. According to John Allen Giles, in the preface to his own edition published by the Caxton Society in 1845, the Chronicon was attributed by both Simon Patrick and Henry Wharton to John of Caleto (or "Caux"), who was an abbot of Peterborough (12501262). Giles reported a marginal note in the manuscript making a similar attribution, besides a similar note at the beginning of the manuscript stating that it belonged to Peterborough Abbey. However, Giles observed that this manuscript attribution was "comparatively modern", and regarded the chronicle's author as unknown. In Giles's view, the Chronicon is "extremely valuable both on account of the numerous facts which it contains, and for the [700 years] which it embraces."
Passage 2:Born in Berlin to the distinguished Prussian military family von Bulow, originally from Mecklenburg, he enlisted in the Prussian Army and was assigned to the 2nd Guards regiment of infantry in 1864. He saw action during the Austro-Prussian War in 1866 and gained distinction at Koniggratz. Von Bulow served through the Franco-Prussian War of 1870 as a junior officer, winning the Iron Cross Second Class. A Captain of the German General Staff in 1877, von Bulow was promoted to Colonel and assigned to the 9th Guards Regiment in 1894. In 1897, von Bulow was a major-general and became director of the Central Department in the German War Ministry. In 1900 he was promoted to lieutenant-general and in 1901 was appointed general commanding the Guards Division. He was Commander of the German III Corps from 1903 until his appointment as Inspector of the German 3rd Army in 1912.
Passage 3:Colonel Marie Augstin Gaston Cros (known as Gaston Cros) (6 October 1861 10 May 1915) was a French army officer and archaeologist. He was born in Alsace and was displaced when that territory was incorporated into the German Empire. He joined the French Army as a lieutenant and saw action in Tonkin before spending several years surveying in Tunisia, receiving the honours of membership of Vietnamese and Tunisian orders and appointment as a chevalier of the Legion of Honour. In 1901 Cros was appointed head of the French archaeological expedition to Girsu, Iraq to continue the work of Ernest de Sarzec. His work over the next five years included the tracing of the thick city wall and for his work there received a letter of commendation from Gaston Doumergue, the Minister of Fine Arts, and the award of the Golden Palms of the Ordre des Palmes Academiques. Promoted to lieutenant-colonel, Cros served in the French protectorate of Morocco from 1913, seeing action in the Zaian War.

Example Input: Question: Is the Washington Aqueduct still in use today? Passage 1: the 1840s and 1850s the largest cities in the U.S. built pipelines to supply drinking water from rivers or lakes. However, the drinking water was initially not treated, since the link between waterborne pathogens and diseases was not yet well known. In 1842 New York City was one of the first cities in the U.S. to tap water resources outside the city limits. It dammed the Croton River in Westchester County, New York, and built an aqueduct from the reservoir to the city. Also in 1842, construction was completed on Chicago's first water works, with water mains made of cedar and a water intake located about into Lake Michigan. In 1848, Boston began construction of a water transmission system. A tributary of the Sudbury River was impounded creating Lake Cochituate, from where the Cochituate Aqueduct transported water to the Brookline Reservoir that fed the city's distribution system. In 1853 Washington, D.C. followed suit by beginning the construction of the Washington Aqueduct to provide water from the Great Falls on the Potomac River.
Passage 2:In the Seven Years' War, he served as adjutant in the staff of Duke Ferdinand of Brunswick and on 1 August 1759 was wounded at Minden. On 14 October 1760 he commanded a Light Company at the Battle of Campen, where he was again wounded. One year later, as Lt. Colonel of the 98th Foot, he participated in the Capture of Belle Ile, off the coast of Brittany. Next, he served at the Battle of Havana in 1762. Later, he was on the staff of Wilhelm, Count of Schaumburg-Lippe during the Spanish invasion of Portugal (1762). In 1763 he retired on half-pay, but in 1772 he received a promotion to Colonel and served as aide-de-camp to King George III.
Passage 3:Down the coast of Africa: The Portuguese reached the westernmost point of Africa in 1444 and in 1458 rounded Cape Palmas where the coast tends eastward. Here the trade winds gave out and they faced the irregular winds near the doldrums and the east-flowing Guinea Current. In 1471 they reached the Gold coast where they found the gold that had previously come by caravan across the Sahara. In 1474 Lopes Goncalves reached the point where the coast turns south and became the first European sailor to cross the equator. In 1475-79 Spain and Portugal fought along the coast. The Treaty of Alcacovas gave the whole area to the Portuguese except for the Canaries. This was the first colonial war and the first colonial treaty. In 1482 Diogo Cao continued south against the Benguela current and the southeast trade winds, reaching the Congo River in 1482 and Cape Cross in Namibia in 1485. In 1487 Bartolomeu Dias reached Cape Voltas near the mouth of the Orange River and stood out to sea. Although the sources are not clear, he may have guessed that there were southern westerlies and was trying a volta do mar. After many days, at about 40 degrees south he discovered the westerlies and turned east. Finding no land after a number of days he turned north and reached Mossel Bay about 400km east of Cape Town. He continued east against the Agulhas current to Algoa Bay where the coast began to turn north. Guessing that he had found the route to India, he turned back, discovered and rounded the Cape of Good Hope and reached Lisbon in 1488. In 1493 Columbus arrived at Lisbon with news of the new world and reported that he had sailed out of sight of land for five weeks.
