question:
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:
Question: How many feet tall is the KCTV-Tower? Passage:The Nelson-Atkins Museum opened its Euro-Style Bloch addition in 2007, and the Safdie-designed Kauffman Center for the Performing Arts opened in 2011. The Power and Light Building is influenced by the Art Deco style and sports a glowing sky beacon. The new world headquarters of H&R Block is a 20-story all-glass oval bathed in a soft green light. The four industrial artworks atop the support towers of the Kansas City Convention Center (Bartle Hall) were once the subject of ridicule, but now define the night skyline near the new Sprint Center along with One Kansas City Place (Missouri's tallest office tower), the KCTV-Tower (Missouri's tallest freestanding structure) and the Liberty Memorial, a World War I memorial and museum that flaunts simulated flames and smoke billowing into the night skyline. It was designated as the National World War I Museum and Memorial in 2004 by the United States Congress. Kansas City is home to significant national and international architecture firms including ACI Boland, BNIM, 360 Architecture, HNTB, Populous. Frank Lloyd Wright designed two private residences and Community Christian Church there.

question:
Question: What years are considered to be the Second Republic? Passage:He studied Law at the University of Oviedo and collaborated with Asturian liberal newspapers. In 1898 he was elected to the Congress as Liberal candidate and was appointed Professor of Roman Law at the University of Oviedo. In 1899, he turned into Republican and in 1906 he was elected Republican congressman. He was one of the organizers of the Liberal Block in 1908 against the Conservative Prime Minister Antonio Maura and of the Republican-Socialist Conjunction in 1909. In 1912, he founded with Gumersindo de Azcárate and José Ortega y Gasset the Reformist Party and the League for the Spanish Political Education. In the 1914 elections, 11 Reformist congressmen were elected. It had also a great success in the municipal elections in Asturias. During the Second Republic he founded the Democratic Liberal Republican Party (Partido Republicano Liberal Democrático), but its electoral results were poor: two deputies in 1932 and ten in 1933, when they supported the right-wing government backed by the Spanish Confederation of the Autonomous Right (CEDA). After the beginning of the Civil War, the revolutionary militias imprisoned and killed him.
