Input: Consider Input: Question: What car did Sommer drive in the Vanderbilt Cup? Passage:Sommer was born in Mouzon, in the Ardennes département of France, into a wealthy Sedan carpet-making family. His father, Roger Sommer, broke the Wright Brothers' record for the longest flight in 1909. It was not until 1931 that Raymond started to display daredevil tendencies of his own, entering motor races in a privateer Chrysler Imperial. The following year, he won the 24 Hours of Le Mans race, despite having to drive over 20 hours solo after his teammate, Luigi Chinetti, retired ill. During the 1930s, Sommer was to dominate the French endurance classic, winning again in 1933 driving an Alfa Romeo alongside Tazio Nuvolari. He also led every race until 1938, only to suffer a mechanical failure, once when 12 laps in the lead. Sommer traveled to Long Island, New York, to compete in the 1936 Vanderbilt Cup where he finished fourth behind the winner, Nuvolari.

Input: Consider Input: Question: Who made more money the year Armstrong recorded with the Hot Seven, Pete Briggs or Art Hodes? Passage:Dodds gained a reputation as a top young drummer in New Orleans. In 1918, Dodds left Sonny Celestin's outfit to play in Fate Marable's riverboat band. A young Louis Armstrong also joined the band, and the two of them were on the boats for three years (from 1918 to 1921). The band played on four different boats, and usually left New Orleans in May and travel to St. Louis, though they also sometimes traveled further north. They played jazz, popular, and classical music while on the boats. Dodds and Armstrong left Fate Marable's band in 1921 due to a disagreement about musical style, and Dodds soon joined King Oliver's Creole Jazz Band. At this time, the personnel in Oliver's band were Joe "King" Oliver on cornet, Baby Dodds' brother Johnny Dodds on clarinet, Davey Jones on alto saxophone, Honoré Dutrey on trombone, Lil Hardin on piano, Jimmy Palao on violin, and Eddie Garland on bass fiddle. They moved to California in 1921 to work with Oliver there, and they played together for about fifteen months. In 1922, the band, excepting Garland, Palao, and Jones, followed Oliver to Chicago, which would be his base of operations for several years. They began playing at the Lincoln Gardens, and Louis Armstrong also joined this outfit. Dodds describes playing with this band as "a beautiful experience". Dodds recorded with Louis Armstrong, Jelly Roll Morton, Art Hodes, and his brother Johnny Dodds. Dodds played in Louis Armstrong's Hot Five and Hot Seven groups. In May 1927 Armstrong recorded with the Hot Seven, which consisted of Johnny Dodds, Johnny St. Cyr, Lil Hardin Armstrong, John Thomas, Pete Briggs, and Baby Dodds. From September to December 1927 the Hot Five Armstrong assembled consisted of Johnny Dodds, Kid Ory, Johnny St. Cyr, Lonnie Johnson, and Baby Dodds.

Input: Consider Input: Question: What was John Holt's career? Passage:Youth activism as a social phenomenon in the United States truly became defined in the mid- to late-nineteenth century when young people began forming labor strikes in response to their working conditions, wages, and hours. Mary Harris "Mother" Jones organized the first youth activism in the U.S., marching 100,000 child miners from the coal mines of Pennsylvania to the U.S. Capitol in Washington, D.C. in 1908. Youth newspaper carriers soon followed. These actions isolated youths' interests in the popular media of the times, and separated young people from their contemporary adult labor counterparts. This separation continued through the 1930s, when the American Youth Congress presented a "Bill of Youth Rights" to the US Congress. Their actions were indicative of a growing student movement present throughout the US from the 1920s through the early 1940s. The 1950s saw the Student Nonviolent Coordinating Committee bring young people into larger movements for civil rights. All the way back in 1959, Rev. Dr. Martin Luther King, Jr. engaged youth activists in protesting against Bull Connor's racist law enforcement practices in Birmingham, Alabama. The youth activism of Tom Hayden, Keith Hefner and other 1960s youth laid a powerful precedent for modern youth activism. John Holt, Myles Horton and Paulo Freire were important in this period. Youthful life and expression defined this era.
