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.

Question: Was Stef the winner in the race where he finished on three wheels? Passage:He was replaced at Ferrari by Austrian Gerhard Berger for and he moved to McLaren as number two driver behind double and reigning World Champion Alain Prost. McLaren weren't as competitive in 1987 as they had been in 1984–1986, with Prost only adding three wins to his tally (and beating the record of 27 Grand Prix wins held by Jackie Stewart with his 28th win in Portugal) and failing to successfully defend his Drivers' Championship. Further podium finishes did follow for the Swede and Johansson finished sixth in the Drivers' Championship. Stefan Johansson's position at McLaren was considered by many as just a stop gap signing by team boss Ron Dennis who had failed to lure Ayrton Senna from Lotus due to him being under contract until the end of 1987 and always intended signing the Brazilian for . Johansson famously finished the 1987 German Grand Prix on three wheels having had a puncture on the last lap. He also finished second behind Prost in Belgium and added further podium finishes in Brazil, Spain and Japan. Despite 11 podiums in three seasons, Johansson was still winless and was not wanted by a top team (he had hoped to join Williams in 1988 as a replacement for the departing 1987 World Champion Nelson Piquet but Williams signed Riccardo Patrese instead). He did return to McLaren in a test-driver capacity in 1991, testing the Honda V12 engine at Suzuka in Japan.
