Input: Consider Input: Question: In what city is the school that Porter attended from 1969-1973? Passage:Claire Porter was born in New Britain, Connecticut, where, as a child, she was a star athlete and danced in a local studio. After she earned her BA in Mathematics from the College of New Rochelle in New York, she became a computer programmer for G.E. Analytical Engineering in Schenectady, New York. Porter returned to her dancing roots after witnessing a performance by Maria Tallchief. She then attended Sonoma State University in California from 1969-1973. At Sonoma State, she studied dance, taught Family Dance, Exercise, and Children’s Dance, and directed a dance company of 12 members. Porter eventually moved from California to Ohio to study dance at Ohio State University. It was there that Porter discovered Laban Movement Analysis and began exploring gestures, acting, writing, and voice. She later received her certification for Laban Movement Analysis at the Laban/Bartenieff Institute of Movement Studies NYC. She earned her MA in Dance from Ohio State and has continued the exploration of gestural movement as a teacher, choreographer and performer.

Input: Consider Input: Question: How many years did the Great Depression last? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

Input: Consider Input: Question: What river runs through the town where Pointon was born? Passage:Pointon was born in Evesham, Worcestershire. He began his football career as an amateur with Coventry City and Redditch Town before joining Birmingham, still as an amateur, in August 1913. The club were fined £5 for playing him in the reserves before the transfer formalities had been completed. An outside left, his performances in the reserves were such that he was invited to a trial for England's amateur team, which proved unsuccessful. He made his debut in the Second Division on New Year's Day 1914 in a 2–0 defeat at Stockport County, and played three times more that season, scoring once, but left in April 1914. He played briefly for Redditch, then joined Walsall shortly before the First World War started. After the war he had a season with Nuneaton Town before returning to the Football League with Coventry City. He played twice in the Second Division for Coventry before a third spell with Redditch and finishing his career at Tamworth Castle.
