Input: Consider Input: Question: How many terms as a senator did Robert Kean's father serve? Passage:Kean was born September 28, 1893, in Elberon, New Jersey. His father, Hamilton Fish Kean (18621941), was a United States Senator from New Jersey and his son, Thomas Kean, served two terms as the Governor of New Jersey. Robert Kean was the great-great-grandson of John Kean, a Delegate to the Continental Congress from South Carolina (17561795). His uncle, John Kean (18521914), was also a United States Senator from New Jersey. His grandson, Thomas Kean, Jr., is presently the Minority Leader of the New Jersey State Senate. His mother, Katherine Taylor Winthrop (18661943), was a descendant of John Winthrop, a wealthy English Puritan lawyer and one of the leading figures in the founding of the Massachusetts Bay Colony, the first major settlement in what is now New England after Plymouth Colony. Winthrop led the first large wave of migrants from England in 1630 and served as governor for 12 of the colony's first 20 years of existence.

Input: Consider Input: 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 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.

Input: Consider Input: Question: Where is Chouinard Art Institute located? Passage:CalArts was originally formed in 1961, as a merger of the Chouinard Art Institute (founded 1921) and the Los Angeles Conservatory of Music (founded 1883). Both of the formerly existing institutions were going through financial difficulties around the same time, and the founder of the Art Institute, Nelbert Chouinard, was mortally ill. The professional relationship between Madame Chouinard and Walt Disney began in 1929 when Disney had no money and Madame Chouinard agreed to train Disney's first animators on a pay-later basis. It was through the vision of Disney, who discovered and trained many of his studio artists at Chouinard (including Mary Blair, Maurice Noble and some of the Nine Old Men, among others), that the merger of the two institutions was coordinated; the process continued after his death in 1966. Joining him were his brother Roy O. Disney, Lulu Von Hagen and Thornton Ladd (Ladd & Kelsey, Architects), of the Los Angeles Conservatory of Music. The original board of trustees at CalArts included Harrison Price, Royal Clark, Robert W. Corrigan, Roy E. Disney, Roy O. Disney, film producer Z. Wayne Griffin, H. R. Haldeman, Ralph Hetzel (then vice-president of Motion Picture Association of America), Chuck Jones, Ronald Miller, Millard Sheets, attorney Maynard Toll, attorney Luther Reese Marr, bank executive G. Robert Truex Jr., Jerry Wexler, Meredith Willson, Peter McBean and Scott Newhall (descendants of Henry Newhall); and the wives of Roswell Gilpatric, J. L. Hurschler, Richard R. Von Hagen.
