Question: Was Hirohito an adult when the San Francisco Peace Treaty was signed? 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.

Question: How long is the railway tunnel opened in 1886? Passage:In 1873, the Hoylake and Birkenhead Railway was authorised to construct two extensions to its lines. One was a short connecting section near to Birkenhead docks, and the other was the extension from Hoylake to West Kirby. The station and the extension were opened on 1 April 1878 as the terminus of the Wirral Railway's route from Birkenhead Park station. The station's original signal box was built in 1886, to a London and North Western Railway (LNWR) design. This signal box was removed and replaced in 1932. After the opening of the Mersey Railway Tunnel in 1886, carriages were operated through Birkenhead Park, every half-hour, all the way to James Street station in Liverpool. As traffic increased, the line into West Kirby was doubled, from a single track, in 1896. After a board meeting on 28 October 1895, it was decided to extend the line from Hooton, into West Kirby. The station was relocated on the western side of the original station, with an enlarged island platform and rebuilt, in 1898-9, in red brick, with a turreted clock tower and mock Tudor frontage. A further platform was constructed for the Hooton line, on the eastern side of the original station. The site of the original station was used for goods sidings. In the present day, this is the site of The Concourse, a community building operated by Wirral Metropolitan Borough Council.
