Q: 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.

Q: Question: How much money was made at the box office by the 1997 David Lynch movie that Mason contributed 2 songs to? Passage:Neil Strauss, a rock critic and reporter for The New York Times, met Marilyn Manson through his work for Spin and Rolling Stone. Strauss initially perceived Manson as a "phony" who had gotten on the gothic rock bandwagon very late; he later came to see Manson as a "really interesting, really intelligent artist" with many talents. He went to talk to Manson at a Holiday Inn in Fort Lauderdale, Florida. Manson asked Strauss to join him in a hot tub, commenting "This is going to be an important piece of press." Strauss wrote a cover story about Manson for Rolling Stone, which in the view of the Chicago Reader Jim DeRogatis "legitimized Manson's emergence as one of the most notorious entertainers of the 90s and an enthusiastic bogeyman for the right". Following the publication of the article, Strauss became Manson's business partner. Later, Manson and Strauss got a deal to write the singer's autobiography for ReganBooks, an imprint of HarperCollins founded by Judith Regan, who was behind Howard Stern's Private Parts (1997). The autobiography shares its title with the Marilyn Manson song "Long Hard Road Out of Hell" (1997) and features an introduction written by film director David Lynch; Manson had previously contributed two songs to the soundtrack of Lynch's film Lost Highway (1997) and would later collaborate with the director on a coffee table book titled Genealogies of Pain (2011).
