Input: Question: Which opera house Easterlin has performed in during his career is the oldest? Passage 1:The Allied occupation of Japan at the end of World War II was led by General Douglas MacArthur, the Supreme Commander of the Allied Powers, with support from the British Commonwealth. Unlike in the occupation of Germany, the Soviet Union was allowed little to no influence over Japan. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. At MacArthur's insistence, Emperor Hirohito remained on the imperial throne. The wartime cabinet was replaced with a cabinet acceptable to the Allies and committed to implementing the terms of the Potsdam Declaration, which among other things called for the country to become a parliamentary democracy. Under MacArthur's guidance, the Japanese government introduced sweeping social reforms and implemented economic reforms that recalled American "New Deal" priorities of the 1930s under President Roosevelt. The Japanese constitution was comprehensively overhauled and the Emperor's theoretically-vast powers, which for many centuries had been constrained by conventions that had evolved over time, became strictly limited by law. The occupation, codenamed Operation Blacklist, was ended by the San Francisco Peace Treaty, signed on September 8, 1951, and effective from April 28, 1952, after which Japan's sovereigntywith the exception, until 1972, of the Ryukyu Islands was fully restored.
 Passage 2:Easterlin received his Bachelor of Music degree from the University of Miami and his Bachelor of Science degree from Florida International University, and after a successful career in corporate advertising, began his performing career in musical theatre before moving into opera. He went on to perform at many of America's leading opera houses and festivals, including the Lyric Opera of Chicago, San Francisco Opera, Los Angeles Opera, Seattle Opera, New York City Opera, Dallas Opera, the Opera Company of Philadelphia, the Ravinia Festival with the Chicago Symphony conducted by Daniel Barenboim for the opening night of the Centennial Season, and Spoleto Festival USA in a new production of Ariadne auf Naxos conducted by Emmanual Villaume. He made his debut at the Glimmerglass Opera Festival in the summer of 2009 as 'The Magician' in a new production of Menotti's The Consul. According to Opera News, Easterlin spent 200 hours learning magic tricks for this production, which included producing a live rabbit on stage. Another unusual role for him was Houston Grand Opera's 2006 all-puppet production of Humperdinck's opera Hansel and Gretel in which he sang the role of the Witch as well as operating her twelve-foot high puppet.
 Passage 3:Dixon attended the College of William and Mary before signing with the Boston Red Sox farm system in as a right-handed pitcher. Despite losing three seasons (1943–45) to military service during World War II, Dixon progressed as far as the Scranton Red Sox of the Class A Eastern League before his release by the Red Sox at the end of the campaign. When he returned to the game in he pitched for unaffiliated clubs in the mid-minors until he became predominantly an outfielder and first baseman in . That season — also his first as a manager — Dixon batted .368 for the Shelby Farmers of the Class D Western Carolina League. His best minor league season, however, would come in when, as the manager and first baseman of the Norton Braves of the Class D Mountain States League, he led the loop in home runs (37) and hits (194), while batting .415 and driving home 162 RBI. Incredibly, Dixon did not lead the MSL in RBI or batting, finishing behind Willie Kirkland (164 RBI) and Leo "Muscle" Shoals (.427).
