Input: Consider Input: Question: What was the New York giants regular season record the year Wally Pipp hit .296, and the Yankees lost to them that same year in the World Series? Passage:In 1918, Pipp hit only two home runs, but batted .304. He missed playing time under the nation's "work or fight" rule during World War I; he worked as a naval aviation cadet at the Massachusetts Institute of Technology. He batted .275 with seven home runs in 1919, as Babe Ruth surpassed him as the best power hitter in the American League. The Yankees moved to strengthen their team after the 1919 season, adding Ruth and fellow outfielder Bob Meusel and third baseman Joe Dugan. Between 1920 and 1924, Pipp had a .301 average, with season averages of 29 doubles, 94 runs scored, and 97 runs batted in (RBI) per season. Led by their strong lineup and additions to the pitching staff, such as Waite Hoyt, the Yankees finished in second place in 1920. Pipp became the cleanup hitter, behind Ruth in the batting order. Pipp hit .296 in 1921, and the Yankees won the American League pennant. However, they lost the 1921 World Series to the crosstown rival New York Giants of the National League.

Input: Consider Input: Question: How long had the Royal Canadian Air Force existed the year that the McDonnell CF-101 Voodoo began being operated by them? Passage:The McDonnell CF-101 Voodoo was an all-weather interceptor aircraft operated by the Royal Canadian Air Force and the Canadian Forces between 1961 and 1984. They were manufactured by the McDonnell Aircraft Corporation of St. Louis, Missouri for the United States Air Force (as F-101s), and later sold to Canada. CF-101s replaced the obsolete Avro CF-100 Canuck in the RCAF's all-weather fighter squadrons. The Voodoo's primary armament was nuclear AIR-2A Genie unguided air-to-air rockets, and there was significant political controversy in Canada about their adoption. Although they never fired a weapon in wartime, the CF-101 served as Canada's primary means of air defence from Quick Reaction Alert facilities at Canadian airbases. The CF-101s were retired in the 1980s and replaced with McDonnell Douglas CF-18 Hornet fighters. Many examples are preserved in museums and parks in Canada and the United States.
