[EX Q]: 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.

[EX Q]: Question: What song on Hammer's debut album samples a song by the same name from BB King? Passage:Before Hammer's successful career (with his mainstream/commercial popularity lasting approximately between the mid-1980s until the late-1990s) and his "rags-to-riches-to-rags-and-back saga", Burrell formed the Christian rap music group Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as "K.B." and then eventually M.C. Hammer once it was produced), was later released by Jon Gibson (aka "J.G."). This was Contemporary Christian music's first rap hit ever (by anyone), in particular by a Caucasian (Gibson) and/or from a duo. The track appeared on Gibson's album Change of Heart (1988), and "Son of the King" showed up on Hammer's debut album Feel My Power (1987) as well as the re-released version Let's Get It Started (1988). Burrell, along with Tramaine Hawkins, performed with Gibson's band doing several concerts in various venues such as the Beverly Theatre in Beverly Hills.

[EX Q]: Question: Who framed the McKinley Tariff? Passage:Like his father, Mellon consistently supported the Republican Party, and he frequently donated to state and local party leaders. Through state party boss Matthew Quay, Mellon influenced legislators to place high tariffs on aluminum products in the McKinley Tariff of 1890. During the early 20th century, Mellon was dismayed by the rise of progressivism and the antitrust actions pursued by the presidential administrations of Theodore Roosevelt, William Howard Taft, and Woodrow Wilson. He especially opposed the Taft administration's investigations into Alcoa, which in 1912 signed a consent decree rather than going to trial. In the aftermath of World War I, he provided financial support to Henry Cabot Lodge and other Republicans in their successful campaign to prevent ratification of the Treaty of Versailles. Mellon attended the 1920 Republican National Convention as a nominal supporter of Pennsylvania Governor William Cameron Sproul (Mellon hoped Senator Philander Knox would win the nomination), but the convention chose Senator Warren G. Harding of Ohio as the party's presidential nominee. Mellon strongly approved of the party's conservative platform, and he served as a key fundraiser for Harding during the presidential campaign.
