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 Jürgen 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 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points 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.

Question: When was the academy founded? Passage 1:He attended schools in Brixen and Innsbruck and served as a nurse during the Franco-Prussian War. In 1871, following his father's wishes, he began studying economics, eventually attending schools in Leipzig, Breisgau and Freiburg, where he was a member of the Corps Suevia Freiburg. His interest in hunting led him to give up his studies and take positions as a game warden and forester, first for the estates of Count Ernst II, then in Schillersdorf, Upper Silesia, for Nathaniel Meyer von Rothschild., but he had to quit due to an illness. After convalescing in Munich an acquaintance, Eduard von Grützner, suggested art as a career, so Pfretzschner studied sculpture with Edmund von Hellmer in Vienna and Ludwig Manzel in Berlin, where he worked from 1891 to 1913, becoming a Professor at the Prussian Academy of Art.
 Passage 2:His 2009 season Schüttler started off at the Chennai Open, beating Prakash Amritraj 6–2, 4–6, 6–1. In the second round, he beat Simon Greul 6–4, 6–2, and in the quarterfinals Björn Phau, 6–2, 7–5. Unfortunately Schuettler had to withdraw from his semifinal match against Somdev Devvarman because of a wrist injury. He also withdrew from the tournament in Sydney. At the Australian Open, he was seeded 30th but lost in the first round to Israeli Dudi Sela 1–6, 6–2, 6–4, 6–4. He also participated in the doubles with Lu Yen-hsun, but they were defeated by Łukasz Kubot and Oliver Marach. In the first round in Rotterdam, he lost to Mario Ančić. He played the Open 13 in Marseille, defeating Laurent Recouderc in the first round 6–1, 6–4.
 Passage 3:Born in Tacoma, Washington to an attorney and his wife who were active New Deal Democrats, Elizabeth Binns wanted to be a lawyer from a young age. Her father sometimes allowed her to skip classes in order to watch him try cases; she graduated from the local public high school at age 16. She then attended Stanford University and graduated with a Bachelor of Arts degree in 1942 at the age of 19. Because so many men were away during World War II, Binns was admitted to the Stanford Law School, and completed one year before marrying Robert L. Fletcher, who was soon assigned to fly anti-aircraft blimps out of Lakehurst, New Jersey. They started a family, and moved back to Lakewood, Washington, after the war. With her parents' assistance in caring for their four young children (and renting out their own house to live in Lakewood), Fletcher resumed her legal education after a decade, now commuting to Seattle to study at the University of Washington School of Law. In 1956 she graduated at the top of her law school class, with a Bachelor of Laws.

Question: What time period did the Antonine dynasty rule? Passage 1:He led the 1901-1904 Swedish Antarctic Expedition, aboard the ship Antarctic. The expedition visited the Falkland Islands before the ship, commanded by seasoned Antarctic sailor Carl Anton Larsen, dropped Nordenskjöld's party off at Snow Hill Island, a small island off the coast of the Antarctic Peninsula. Nordenskiöld overwintered at Snow Hill Island, while Antarctic returned to the Falklands. The following summer Larsen brought her south, intending to retrieve the Nordenskiöld party, but she became trapped in ice which eventually crushed her hull, forcing Larsen and his crew to overwinter in a hastily constructed shelter on Paulet Island. Larsen and Nordenskjöld finally rendezvoused at their fall-back rescue hut at Hope Bay in late 1903, where they were picked up by the Argentine Navy corvette ARA Uruguay (commanded by Julián Irízar), which had been dispatched when Antarctic had failed to make her appointed return to South America the previous year. Despite its end and the great hardships endured, the expedition was considered a scientific success, with the parties having explored much of the eastern coast of Graham Land, including Cape Longing, James Ross Island, the Joinville Island group, and the Palmer Archipelago. The expedition, which also recovered valuable geological samples and samples of marine animals, earned Nordenskjöld lasting fame at home, but its huge cost left him greatly in debt.
 Passage 2:Lange returned to television for a 1966 role on the series The Fugitive (1963). She starred from 1968 to 1970 on the television series, The Ghost & Mrs. Muir for which she earned two Emmy Awards and a Golden Globe Award nomination. This success was followed by three seasons on The New Dick Van Dyke Show as Dick Van Dyke's wife, Jenny Preston, from 1971 to 1974, after which she declined to return for a fourth season of the show. She also appeared in twelve television movies, one being Crowhaven Farm where she played the role of a witch. In 1977, she returned to the Broadway stage where her acting career had originally begun. She also played the murdered wife of Charles Bronson's vigilante character in Death Wish (1974). In 1985, she appeared in , and in 1986, she took a role as Laura Dern's mother in David Lynch's Blue Velvet. She took a Broadway role in Same Time, Next Year and then made appearances in the television movie based on Danielle Steel's Message from Nam and in Clear and Present Danger (1994).
 Passage 3:Commodus, the last emperor of the Antonine dynasty, remembered by contemporaneous chronicles as an unpopular ruler notorious for his extravagance and cruelty, was assassinated in 192. Without sons to be his heir, a struggle for power immediately broke out amongst the governors of the most important provinces. Pertinax was elevated to the purple and recognized by his peers, but following his murder by a restive Praetorian Guard, Septimius Severus decided to make his bid for power and usurped the throne. Although initially a usurper, Severus managed to remain in power for the next 18 years and died a natural death while campaigning in northern Britain. The death of Severus Alexander (the last emperor of the Severan dynasty) in 235 triggered what historians call the crisis of the third century. In this period, from 235 to the accession of Diocletian and the establishment of the Tetrarchy in 286, Rome saw 28 emperors of whom only two had a natural death (from the plague). However, there were also 38 usurpers who raised revolts across the Empire, a clear sign that the security of the frontiers was not the only problem within the Roman world. Usurpation attempts were a constant worry for the emperors in this period; it was a too common method of acceding the throne. Successful usurpers were usually either provincial governors, commanders of a large grouping of Roman legions, or prefects of the Praetorian Guard, which had control of Rome, where the Imperial palace still lay.
