Question: How many features did Brecht and Dudow work on together? Passage: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.

Question: What is the population of the city where Wayne Russell is from? Passage:In July 2008, Kamloops MLA Claude Richmond announced he would not seek re-election in the May 2009 provincial election. Consequently, Lake announced that he would not stand for re-election as mayor but would instead seek to replace Richmond. With MLA Kevin Krueger moving to the new Kamloops-South Thompson riding, Lake was unopposed for BC Liberal nomination in the Kamloops-North Thompson. The election was expected to be close but Lake ultimately defeated the NDP candidate Doug Brown, student April Snowe for the Green Party, Clearwater resident Wayne Russell of the Refederation Party, and the Work Less Party's Keston Broughton. Lake's BC Liberals won the election and formed a majority government under Premier Gordon Campbell. In the first two sessions of the 39th Parliament Lake was appointed to the Select Standing Committee on Aboriginal Affairs and the Select Standing Committee on Health, however neither of those committees held any meetings. Premier Campbell did not include Lake in the cabinet but he was appointed as the Parliamentary Secretary for the Ranching Task Force under the Ministry of Agriculture and Lands. The Ranching Task Force began its work in July to review the province's role in the ranching industry, an industry which had been facing setbacks such as declining cattle prices and fewer exports following a Bovine spongiform encephalopathy outbreak and a strengthen currency value (relative to the US dollar). The task force's final report and recommendations were sent to the Minister of Agriculture and Lands in November 2009.

Question: Which war lasted short period of time, the war when the castle was strengthened or the war that devastated Mouscron? Passage:In 1575, in the middle of the Wars of Religion, the castle was strengthened. It was nevertheless besieged and taken by the Geuzen, locally known as the Hurlus in 1579, before being taken back three months later. In 1627, Philip IV of Spain promoted the seigneury to the rank of county. The Franco-Dutch War under Louis XIV devastated this mostly agricultural region. Mouscron and the surrounding area became French after the Treaty of Aix-la-Chapelle (1668). Part of it rejoined the Southern Netherlands after the Treaty of Nijmegen (1678), which drew the frontier right through its territory. It was finally completely ceded to the Southern Netherlands under the terms of the Treaty of Utrecht in 1713. The textile industry started in Mouscron in the 1760s thanks to the imposition by Lille of a ban on the fabrication of molletons, a mixture of flax and wool, in Roubaix and Tourcoing. With the Battle of Fleurus (1794), Mouscron went back to France.
