You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: What were the two sides fighting in the Battle of Point Pleasant? Passage 1:Originally from Canada, Macmillan received a Bachelor of Science degree in engineering physics in 1950 from Queen's University. He later attended the University of Cambridge from 1952 to 1955, where he was a member of Gonville and Caius College, and earned a Master of Science degree. During his studies, he published several papers: in the Journal of the Royal Aeronautical Society, "Viscous effects on Pitot tubes at low speeds"; in the Aeronautical Journal, "Viscous effects on flattened Pitot tubes at low speeds"; and in the Journal of Scientific Instruments, "Liquid manometers with high sensitivity and small time-lag". Following completion of his degree, Macmillan returned to Canada and took employment helping development of the AIM-7 Sparrow. By the early 1960s he had left the aeronautical industry and moved to British Columbia where he began working in the pulp and paper sector.
 Passage 2:Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.
 Passage 3:The New York Giants visited the Washington Redskins on September 11, 2011, the first Sunday of the regular season, to commemorate the tenth anniversary of the September 11 attacks in which Washington, D.C. and New York City were both targeted, as well as the first such anniversary since the killing of Osama bin Laden in May. Due to the proximity of Baltimore with Washington as well as the proximity of Pittsburgh with the site where United Airlines Flight 93 crashed, the Pittsburgh Steelers visited the archrival Ravens at M&T Bank Stadium in Baltimore. It marked the first time the two teams played in a season-opening game since 2003, as their heated rivalry usually prompts their games to be scheduled later in the season. There had been some speculation that the Giants and their same-city rival, the New York Jets, could have played each other that day since the two were scheduled to play each other in 2011; the Jets were the designated home team at MetLife Stadium in the matchup which had been predetermined due to the NFL's scheduling formula. However, the Jets instead hosted the Dallas Cowboys.
