Question: What teams had the newly hired head coach and offensive co-ordinator for the Argonauts worked for previously? Passage:However, with the 1982 season came the hiring of Bob O'Billovich as head coach and Mouse Davis as offensive co-ordinator. Davis implemented the run and shoot offense, and the Argos enjoyed a turnaround, going 9–6–1 that year; Condredge Holloway was the CFL's most outstanding player. The team ultimately fell short in their quest for a Grey Cup, losing 32–16 in a driving rainstorm to the mighty Edmonton Eskimos (in what would be the last of their five consecutive Grey Cup titles) in the final in front of a disappointed crowd at Exhibition Stadium. The 1983 season finally brought the championship home. The Argos finished 12–4 and Terry Greer set a CFL record with 2,003 receiving yards. Joe Barnes and Condredge Holloway were a potent duo at quarterback. The Double Blue returned to the Grey Cup, this time facing the BC Lions at BC Place Stadium in Vancouver. Despite the hostile crowd, Toronto defeated BC 18–17 to win their first Grey Cup since 1952. The Argos were generally competitive for the remainder of the 1980s, thanks in large part to talented players such as Gill "The Thrill" Fenerty and Darrell K. Smith, but a return to the glory of 1983 proved elusive (outside of an appearance in the 1987 Grey Cup game, in which they lost in the last minute to the Edmonton Eskimos 38–36).

Question: How long passed between the Potsdam Declaration and the San Francisco Peace Treaty signing? Passage: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.
