Input: Question: How many students are enrolled at the college where Wright studied physics? Passage:Born in Toronto, Ontario, Canada in 1887, the son of an insurance executive, Wright grew up in the Toronto neighbourhood of Rosedale. He was educated at Upper Canada College where he also became head boy. Despite wearing glasses, he excelled in sports and his spirit of adventure saw him spend some of his youth prospecting and canoeing in Canada's unmapped Far North. He studied Physics at the University of Toronto and won a scholarship for postgraduate study at Gonville and Caius College, Cambridge, England, undertaking research in cosmic rays at the Cavendish Laboratory from 1908-10. There he met Douglas Mawson, who had recently returned from Shackleton's 1907-9 British Antarctic Expedition, known as the Nimrod Expedition. Upon learning of Scott's forthcoming expedition to the geographic South Pole, Wright applied to join but was rejected. Undaunted, he walked from Cambridge to London, where he applied in person; this time, Scott accepted, and Wright was hired as expedition glaciologist and assistant physicist.
