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 games did Millwall lose the season they had 11 consecutive clean sheets in? Passage:In the 1925–26 season Millwall had 11 consecutive clean sheets, a Football League record, which they hold jointly with York City and Reading. Millwall became known as a hard-fighting Cup team and competed in various memorable matches, notably defeating three-time league winners and reigning champions Huddersfield Town 3–1 in the third round of the 1926–27 FA Cup. In the 1927–28 season Millwall won the Third Division South title and scored 87 goals at home in the league, an English record which still stands. Matches against Sunderland and Derby County saw packed crowds of 48,000-plus in the 1930s and 1940s. Their 1937 FA Cup run saw Millwall reach the semi-finals for the third time, and a fifth-round game against Derby still stands as Millwall's record attendance of 48,762. Millwall were the 11th best supported team in England in 1939, despite being in the Second Division. Millwall were one of the most financially wealthy clubs in England. The club proposed plans to improve the Den and signed international players. Winger Reg 'JR' Smith was capped twice, scoring two goals for England in 1938. The Lions were pushing for promotion to the First Division toward the end of the decade, but one week into the 1939–40 season, World War II broke out and Millwall were robbed of their aim.
