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.

Question: How long was Patasse leader of the MLPC? Passage:On 3 March 1982, opposition politician and leader of the MLPC party, Ange-Félix Patassé, returned from exile to the Central African Republic and staged an unsuccessful coup against General André Kolingba (who himself took power in the 1981 coup d'état) with the help of a few military officers, such as General François Bozizé, who accused Kolingba of treason and proclaimed the change of power on Radio Bangui. Four days later, having failed to gain the support of the Central African Armed Forces, Patassé went in disguise to the French Embassy in the Central African Republic to seek refuge. After heated negotiations between the Kolingba government and France, Patassé was allowed to leave for exile in Togo. Bozizé fled to the north of the country with 100 soldiers, before obtaining refuge in France.

Question: What other notable people studied the same disciplines in the university Kapp was at between 1842 and 1844? Passage:Kapp received his Abitur from Gymnasium “Hammonense”, the same educational institution where his father held the position of principal. Between 1842 and 1844, Kapp studied law and philosophy at the University of Heidelberg. There, at his uncle Christian Kapp's (1798–1874) house, he met the philosopher Ludwig Feuerbach. Not only did they become close friends; Feuerbach's criticism of religion, which also strongly influenced Karl Marx, had a great impact on Kapp's attitude towards life as well. Other acquaintances from his time as a student were Ludwig Bamberger (1823–1899), who would later become a banker, the author Berthold Auerbach (1812–1882) of Heidelberg and the poet Bettina von Arnim (1785–1859) of Berlin. From 1844 on, Kapp studied at the University of Berlin and voluntarily served in the army for one year. In Berlin, he was already working as a journalist for the utopian socialist magazine called "Westfälisches Dampfboot" ("Westfalian Steamboat").
