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: How long did the person serving as Malyan Prime Minister during 1958 serve in office? Passage:Relations with the former state of South Vietnam were established when South Vietnam recognised the Federation of Malaya's independence on 1957. From that point, Malaya provided aid to the South Vietnamese regime in its fight against the Viet Cong and North Vietnamese army. Malayan Prime Minister Tunku Abdul Rahman made a first visit on 1958 which was reciprocated twice by the South Vietnamese President Ngô Đình Diệm on 28–31 January 1958 and in October 1961. By 1963, when Malaya transformed into Malaysia (with an additional territory in the island of Borneo), the main government in Kuala Lumpur worried the influence of North Vietnamese communists would threaten its existence in accordance to the Domino theory, thus changing its position to become very supportive of the American involvement in the Vietnam War as Malaysia had also experienced a communist insurgency of its own. Tunku Abdul Rahman then expressed these concerns in December 1966 and called on the United States and the United Kingdom to provide increased logistical support to war efforts in Vietnam. Malaysia hosted training courses in public administration and jungle warfare for government officials, and provided motorcycles to bolster the South Vietnamese police and military logistical capabilities. Towards the end of the Vietnam War in 1975, Malaysia closed its embassy in Saigon in two stages; first it withdrew the embassy dependants on 12 April 1975, before a complete closure 16 days later—two days before the fall of Saigon. Malaysia had also extended recognition to the short-lived Provisional Revolutionary Government of the Republic of South Vietnam within days of its formation in May 1975, citing Malaysia's impartial position on political ideology and social system.

Input: Consider Input: Question: Is the company that originally signed the Rising Sons based in the same state as the one that released their 1992 album? Passage:In 1964 he moved to Santa Monica, California, and formed Rising Sons with fellow blues rock musician Ry Cooder and Jessie Lee Kincaid, landing a record deal with Columbia Records soon after. The group was one of the first interracial bands of the period, which likely made them commercially unviable. An album was never released (though a single was) and the band soon broke up, though Legacy Records did release The Rising Sons Featuring Taj Mahal and Ry Cooder in 1992 with material from that period. During this time Mahal was working with others, musicians like Howlin' Wolf, Buddy Guy, Lightnin' Hopkins, and Muddy Waters. Mahal stayed with Columbia after the Rising Sons to begin his solo career, releasing the self-titled Taj Mahal in 1968, The Natch'l Blues in 1969, and Giant Step/De Old Folks at Home with Kiowa session musician Jesse Ed Davis from Oklahoma, who played guitar and piano (also in 1969). During this time he and Cooder worked with the Rolling Stones, with whom he has performed at various times throughout his career. In 1968, he performed in the film The Rolling Stones Rock and Roll Circus. He recorded a total of twelve albums for Columbia from the late 1960s into the 1970s. His work of the 1970s was especially important, in that his releases began incorporating West Indian and Caribbean music, jazz and reggae into the mix. In 1972, he acted in and wrote the film score for the movie Sounder, which starred Cicely Tyson. He reprised his role and returned as composer in the sequel, Part 2, Sounder.
