[Q]: 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.

[Q]: Question: Which president saw the establishment of the recreation area that contains the lower of the San Juan River? Passage:From there it flows west through the Navajo Nation, turning northwest near Shiprock and its namesake monolith, crossing very briefly back into southwest Colorado (within half a mile (0.8 km) of the Four Corners quadripoint) before entering southeastern Utah. West of Bluff, Utah the river slices through the Comb Ridge and enters a series of rugged winding canyons, often over in depth. The lower of the San Juan River, in a remote portion of the Glen Canyon National Recreation Area, are flooded by Lake Powell, which is formed by Glen Canyon Dam on the Colorado River. The San Juan joins the Colorado in San Juan County, Utah at a point about to the north of Navajo Mountain and northeast of Page, Arizona.

[Q]: Question: What is the full given name of the Bruins' first-year head coach? Passage:The 2018 UCLA Bruins football team represented the University of California, Los Angeles in the 2018 NCAA Division I FBS football season. The Bruins were led by first-year head coach Chip Kelly and played their home games at the Rose Bowl. UCLA was a member of the Pac-12 Conference in the South Division. They began the season 0–4 for the first time since 1971, as well as 0–5 for the first time since 1943, before finally winning their first game, in dominating fashion, against Cal. However, despite failing to improve upon their previous season's output of 6 wins and 7 losses and failing to qualify for a bowl game, the Bruins later defeated the USC Trojans to end a three-game losing streak in their crosstown rivalry. The Bruins finished 3–9 overall, their worst record since 1971. They went 3–6 in Pac-12 play, finishing in fifth place in the South Division.
