question:
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:
Question: How long had Mark Vaile held his post before resigning in 2008? Passage:The coalition total was reduced to 64 seats when Rob Oakeshott, former state Nationals turned independent MP, won the seat of Lyne at the September 2008 Lyne by-election, resulting from the resignation of former Howard minister and Nationals leader Mark Vaile. The April 2008 Gippsland by-election, resulting from the resignation of the former Howard minister and Nationals MP Peter McGauran, saw the Nationals' Darren Chester retain the seat, receiving a swing of 6%. The Liberals suffered a swing in the September 2008 Mayo by-election resulting from the resignation of former Howard minister and Liberal leader Alexander Downer, and came close to losing the seat to the Greens candidate. The Liberals retained seats at the Bradfield and Higgins by-elections in December 2009. The member for Ryan, Michael Johnson, was expelled from the Liberal National Party on 20 May 2010, reducing the Coalition to 63 seats.

Question: When was the third time that Deng Xiaoping served? Passage:The Secretary-general of the Communist Party of China () was a senior leadership position of the Communist Party of China to assist in the daily work of the Central Committee.
