[Q]: Question: Did the war that Hurst served in last longer than 2 years? Passage:Aurthur Frederick Hertz was born in Bradford to Fanny Mary and William Martin Hertz, a merchant of German Jewish descent. Hertz changed the spelling of his surname to Hurst in 1916. He attended Bradford Grammar School and Manchester Grammar School before graduating from Magdalene College, Oxford in 1904. He joined the staff of Guy's Hospital in 1906 and ran his own private practice before serving in World War I as a consulting physician stationed in Salonika. From 1916 to 1918, Hurst led the neurology department at Netley Hospital. Seale-Hayne College was repurposed as a military hospital that same year. Hurst moved there to help with treatment of shell shock, working at Netley until 1919. After the war, Hurst relocated his private practice to Windsor and retired in 1939. Upon his retirement, Hurst became a consulting physician and served on Guy's Hospital board of governors. Hurst was knighted in 1937 six years after his older brother Gerald Berkeley Hurst. He died in Birmingham in 1944, aged 65.

[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 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.

[Q]: Question: Who wrote the first song that Graham Clark learned to sing? Passage:Graham Clarke was born in Holy Name Medical Center in Teaneck, New Jersey on July 11, 1970. Clarke's parents, Lorain Maria Clarke (nee Meola), a homemaker, and Thomas Michael "Moose" Clarke, a stockbroker were married in 1960 and had three children before Graham: Thomas in 1961, Dennis in 1962, and Martin in 1965. He spent the first seven years of his life in a split-level home in Dumont, New Jersey. He was frequently in the room when his older brother Tommy would have guitar lessons with musician Bob Berger. Bob noted one time when a screaming Graham had scarlet fever "That boy's screaming on key! That's a C note." Such exposure to music had an obvious influence on him and there is an oft-told family story that claims the first song Graham ever learned to sing was "Me and Julio Down by the Schoolyard," a popular song Tommy was learning on the guitar at the time. At the age of seven, his family moved one town over to Oradell, where he attended St. Joseph Grammar School, and later Bergen Catholic High School. Neither school had a music program so Graham taught himself how to play the guitar using his brother's old fake books.
