[EX Q]: Question: Does the college that Harrison graduated from in 1922 have more students than the one he graduated from in 1924? 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: What is the mascot of the team that Mike Sanford Jr. left to join the Irish? Passage:The off-season brought a few changes to the coaching staff, as Notre Dame lost three assistant coaches to other opportunities: Kerry Cooks left the coaching staff to take the same position at the University of Oklahoma. Matt LaFleur departed to take the same position for the Atlanta Falcons of the NFL, and Tony Alford left the university to take the same position at Ohio State University.

Autry Denson, Notre Dame's all-time leading rusher and Running Backs coach at the University of South Florida, accepted the same position on the coaching staff.

[EX Q]: Question: How long is the river that bordered the land occupied by Bavarians? Passage:In the meantime, the Germanic tribe of the Bavarii (Bavarians), vassals of the Franks, had developed in the 5th and 6th century in the west of the country and in what is now known as Bavaria, while what is today Vorarlberg had been settled by the Alemans. In the northern alps the Bavarians had become established as a stem dukedom around 550 AD, under the rule of the Agilolfings until 788 as an eastern outpost of the Frankish Empire. At that time the lands occupied by the Bavarians extended south to current South Tyrol, and east to the river Enns. The administrative center was at Regensburg. Those groups mixed with the Rhaeto-Romanic population and pushed it up into the mountains along the Puster Valley.
