Example Input: Question: What state was John Baker from? Passage:The area was at the centre of the Aroostook War, a skirmish over boundary lines between the U.S.A. and what was then British North America. Originally confined to a disagreement between the State of Maine and the Colony of New Brunswick, the dispute eventually spread to involve the Government of the United States in Washington, D.C. and the British Colonial Administration in Quebec City, seat of the Governor General of Canada, who had supreme authority over all of British North America, including New Brunswick. In the wake of this international conflict, a small fortification (Fortin du Petit-Sault) was built in anticipation of a possible attack by the Americans, to complement the much larger fortification located at Fort Ingall (now Cabano) in nearby Canada (now Quebec). One of the central figures at the origin of the conflict was American-born industrialist "Colonel" John Baker, who had established sawmills and other lumber-related industries on the eastern shores of the Saint John river, an area claimed by the British that Baker wanted to be declared part of Maine as he was a fiercely nationalist American.
