Input: Consider Input: 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.

Input: Consider Input: Question: Which company manufactured the rifle that the Bundeswehr replaced in 1997? Passage:The Heckler & Koch G36 is a 5.56×45mm assault rifle, designed in the early 1990s by Heckler & Koch in Germany as a replacement for the heavier 7.62mm G3 battle rifle. It was accepted into service with the Bundeswehr in 1997, replacing the G3. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine. The G36 was made with the extensive use of lightweight, corrosion-resistant synthetic materials in its design; the receiver housing, stock, trigger group (including the fire control selector and firing mechanism parts), magazine well, handguard and carry handle are all made of a carbon fiber-reinforced polyamide. The receiver has an integrated steel barrel trunnion (with locking recesses) and a nylon 66 steel reinforced receiver. The standard German Army versions of the G36 are equipped with unique a ZF 3×4° dual optical sight that combines a 3× magnified telescopic sight and an unmagnified reflex sight mounted on top of the telescopic sight. Widely distributed, it has been adopted by over 40 countries and prompted other nations to develop similar composite designs, such as the FX-05 Xiuhcoatl.

Input: Consider Input: Question: What year did the theater first open where a reworked and more successful West End production opened on July 1, 1998? Passage:Steinman provided lyrics for Andrew Lloyd Webber's musical Whistle Down the Wind, which opened in Washington, D.C. in December 1996. However, it received poor reviews and the Broadway run, scheduled for the following April, was cancelled. A reworked and more successful West End production opened at the Aldwych Theatre on July 1, 1998. In addition to a full-length cast album for the London production, an album was released of well-known performers singing pop versions of the songs from the show. This album was produced by Steinman, as usual with Steven Rinkoff. Those performers include Tom Jones, Tina Arena, Boyzone, Elaine Paige, Donny Osmond, The Everly Brothers, Meat Loaf, Boy George, Sounds of Blackness, Bonnie Tyler, Michael Ball, and Lottie Mayor. One track, "No Matter What" performed by Boyzone, reached the peak position on the pop charts in many countries. The same track appeared on a Boyzone album and their greatest hits album. As of 2019, Boyzone's 1998 recording of "No Matter What" is the most recent new song or project written at least in part by Steinman, or to contain any new work of his at all, to achieve major, chart-topping success. The track "Whistle Down the Wind", performed by Tina Arena, from the same album, also had some chart success. There was also a single released in the U.K., for charity, of children from Red Hill Primary School and Sylvia Young Theatre School performing "When Children Rule The World". The singers were called the "Red Hill Children", and the single peaked at #40 on the U.K. singles charts.
