[Q]: Question: What other teammates had Roberts had before partnering with Lawson? Passage:Lawson accepted an offer from Yamaha to contest the 500cc World Championship as Kenny Roberts' teammate for the 1983 season. Lawson spent the 1983 season learning the ropes of the Grand Prix circuit. In 1984, Lawson began winning regularly and won the 1984 World Championship. It would mark the first of four world titles Lawson would go on to win. In 1985, he won the prestigious Imola 200 pre-season race. After winning two more titles for Yamaha in 1986 and 1988, Lawson shocked the racing world by announcing he would be leaving Yamaha to sign with their arch-rivals Rothmans Honda as teammate to his own archrival, Australia's 1987 World Champion Wayne Gardner. By switching teams, Lawson also fulfilled his desire to work with Erv Kanemoto. After Gardner crashed and broke his leg during the third round at Laguna Seca, Lawson went on to win the 1989 title for Honda, becoming the first rider to win back-to-back championships on machines from different manufacturers. By winning with both Yamaha and Honda, Lawson silenced his critics who believed he would not be as successful away from the factory Marlboro Yamaha team.

[Q]: Question: How long was the person that Shields succeeded in 1911 Captain the the team? Passage:Shields played first for Leicestershire in 1906 and became a regular player as wicketkeeper in 1907, thereafter playing fairly regularly until the end of the 1910 season. He succeeded Sir Arthur Hazlerigg as captain for the 1911 season with an extremely poor side: Vivian Crawford, a mainstay of the batting, had departed for Sri Lanka and fast bowler Thomas Jayes was able to play only two matches because of the tuberculosis that led to his early death; in addition, Ewart Astill, the other reliable bowler of previous years, lost form so badly that he lost his place in the team. Wisden Cricketers' Almanack noted that "no one but a sanguine man of happy disposition could have gone through the season at all complacently". In 24 first-class matches, Leicestershire lost 18 times and gained just a single victory, though they did not finish bottom of the County Championship because Somerset's record was even worse. The single victory was one of the sensational matches of the season: Yorkshire, in the match after Wilfred Rhodes' benefit match, were shot out for just 47 by John King's left-arm medium pace and Leicestershire won by an innings.

[Q]: Question: How many days do the symptoms last of the virus Hodes isolate from the brain of a child who died? Passage:Hodes worked as an intern and resident at the Children's Hospital of Philadelphia until 1935, when he moved to Baltimore to take up a position at the Harriet Lane Home of Johns Hopkins Hospital as the dispensary director. In 1936, he developed a method that used ultraviolet light to reduce the infectiousness of viruses, a technique that later was used to create commercial vaccines against rabies and influenza. He became a pediatrician at Johns Hopkins in 1938 while also serving as the medical director of Sydenham Hospital for Communicable Diseases. During an outbreak of diarrhea in 1942, he isolated the first virus known to cause diarrhea, later identified as rotavirus. The same year, he became the first to isolate the measles virus from the brain of a child who had died from measles encephalitis. While stationed in Guam with the U.S. Navy in World War II, he discovered that the Japanese encephalitis virus was spread by mosquitoes. Hodes continued working in Baltimore after World War II, and started teaching at the Johns Hopkins School of Medicine and School of Hygiene, as well as the University of Maryland School of Medicine.
