[EX 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.

[EX Q]: Question: Which of the Sotto brothers who became senators is the eldest? Passage:Political families started becoming more apparent in the national political scene after World War II and gradually turned into hereditary politics, especially in the provinces. In 1946, Vicente Sotto became a senator after his brother Filemon Sotto previously held a position in the Senate before the war. The 60s saw more frequent instances of relatives getting elected in the Senate such as the election of the brother of then President Ramon Magsaysay; of Magnolia Antonino as Senator after her husband Senator Gaudencio died; of Sergio Osmeña Jr. who was the son of 4th President Sergio Osmeña Sr.; of Gerardo Roxas who was another son of a previous president; and of Benigno Aquino Jr. who was the son of Benigno Sr.. During the martial law years, it only became worse as Marcos named his wife Imelda as the governor of Metro Manila while his son Bongbong became the governor of Ilocos Norte.

[EX Q]: Question: Was this the first time the San Sebastian International Film Festival being held when One-Eyed Jacks won a Golden Shell award? Passage:Pellicer's first acting role, albeit only her second movie to be released, was the Paramount Pictures production One-Eyed Jacks. In the movie, Pellicer played Louisa, the stepdaughter of Karl Malden and the lover of Marlon Brando. Mexican actress Katy Jurado also appeared as Louisa's mother. The production of the movie was much-delayed, and the original director Stanley Kubrick left along with screenwriter Sam Peckinpah, leaving Brando to finish the movie – the only time Brando was credited with directing a movie. So even though production started in 1958, the movie was not released until 1961. European response was positive, and in July 1961 the movie received the Golden Shell (Concha de Oro) at the San Sebastián International Film Festival. In addition, Pellicer was awarded the prize for best female performer, with reviews comparing her to Audrey Hepburn. In the United States, the response was more mixed and the movie received only one Academy Award nomination, for Charles Lang's cinematography.
