Example Input: 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.

Example Input: Question: What country was Hope sent to after Erskine's death? Passage:Hope joined the Scots Brigade as a cadet in 1778. The Brigade, in the service of the Dutch Republic, was then stationed at Bergen op Zoom and later moved to Maastricht. He had reached the rank of Captain when like other officers he left the Dutch service in 1782 during the Fourth Anglo-Dutch War and was on half-pay until 29 September 1787, when he joined the 60th Foot (Royal American Regiment), but the regiment was reduced and he was briefly on half-pay again before joining the 13th Light Dragoons on 30 June 1788. In February 1793, shortly after the French Revolutionary War had begun, Hope served as aide-de-camp to Sir William Erskine in the Flanders Campaign. On 25 March 1795, a few days after Erskine's death, Hope was promoted to major in the 28th Light Dragoons, becoming lieutenant-colonel of that regiment on 20 February 1796. Sent to the Cape Colony, the 28th, under Hope's command, helped to rebuff a Dutch attempt in August, to reclaim the colony.

Example Input: Question: Who did Robert Riddell rebell against in Woodstock? Passage:Henry Scott Riddell was born on 23 September 1798 in Sorbie, near Langholm, Dumfriesshire, the third child of seven to Robert Riddell, a shepherd, and his wife Agnes (née Scott). His father was reportedly an associate of the Scottish poets James Hogg, the Ettrick Shepherd, who would occasionally visit their household and recite his own poetry to the children, and Walter Scott, as well as Sir Pulteney Malcolm. His elder brother, Borthwick Riddell, known as The Piper, was a locally renowned player of the bagpipes who notably played at the wedding of John Russell, 1st Earl Russell to Lady Frances Anna-Maria Elliot-Murray-Kynynmound, daughter of Gilbert Elliot, 2nd Earl of Minto, on 20 July 1841. His younger brother, Robert Riddell, emigrated to Canada and was an early pioneer of Beverley Township in Ontario. He also participated in the Upper Canada Rebellion, coming to be known as The Chief, leading dozens of men from County Wentworth in a march to Woodstock, Ontario.
