In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Example 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.

Example Input: Question: Was his mother still alive when Benigno Simeon Aquino III took the oath? Passage:By tradition, it is also the chief justice who swears into office the President of the Philippines. One notable deviation from that tradition came in 1986, and later again in 2010. Due to the exceptional political circumstances culminating in the People Power Revolution, on February 25, 1986, Corazon Aquino took her oath of office as President before then Associate Justice Claudio Teehankee in San Juan just minutes before Ferdinand Marcos took his own oath of office also as President before Chief Justice Ramon Aquino. Marcos fled into exile later that night. More than two decades afterwards, Benigno Simeon Aquino III followed in his mother's footsteps (with almost similar reasons) by having then Associate Justice Conchita Carpio-Morales to administer his oath of office, rather than then Chief Justice Renato Corona (who was eventually impeached halfway through Aquino's term). Six years later, in 2016, Rodrigo Duterte took his oath of office before Associate Justice Bienvenido Reyes, his classmate at San Beda College of Law, instead of Chief Justice Maria Lourdes Sereno (who would eventually be removed thru quo warranto after it was determined that she had been unlawfully holding office ab initio).

Example Input: Question: Which disease shows symptoms sooner after infection, the measles encephalitis virus or the virus Hodes discovered in Guam that was spread by mosquitoes? 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.
