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: On what date did Morsi take office? Passage:Following the Egyptian revolution of 2011 as part of the regional Arab Spring protests, Mubarak was ousted and the following year Mohamed Morsi who is backed by the Muslim Brotherhood won Egypt's first democractic elections. In 2013 Morsi was removed from power in a coup led by Abdel Fattah el-Sisi. Sisi has called for religious tolerance and has cracked down and banned the Muslim Brotherhood. He has closed thousands of mosques and has banned 'burkinis' on some beaches. A The Economist report in 2017 stated that Egyptians were turning more secular again, with supporters of sharia law dropping by more than half since 2011, people praying less than before, and gender equality now being widely accepted. The government has also acted to preserve its Jewish heritage through the restoration of the abandoned Eliyahu Hanavi Synagogue in Alexandria in 2017.

Question: How old was the singer who recorded "Midnight Sun" when it premiered? Passage:"Midnight Sun" is a song recorded by the Romanian female singer Elena Gheorghe. The song was recorded in summer 2010 and premiered on November 15, 2010, on Gheorghe's official YouTube channel. It was released under Cat Music exclusively in Romania. The song has more house influences than the previous number-one hit "Disco Romancing". It was sent to the mainstream radio stations in late November and it is promoted as the second single taken from Gheorghe's album entitled Disco Romancing. Lyrically, the song describes the shiver a millionaire wannabe guy gets when he sees Elena dancing. The song had its official radio premiere on the Romanian National Day, at radio ZU, though it premiered on Kiss FM a week earlier. Elena performed "Midnight Sun" live, on December 31, during a New Year special show, held by Pro TV. The music video was already shot in Bucharest and it was released via YouTube on May 13, 2011. The video features many special effects as well as the track listing for Gheorghe's upcoming album. The song peaked at number-one the Radio Top 50 and charted within the top ten in two other Romanian charts. In the official Romanian Top 100 it peaked at number-ten, thus making it Elena's fifth song to enter the top ten in Romania, after "Soarele meu", "Vocea ta", "The Balkan Girls" and "Disco Romancing". The song was performed at many dates throughout Romania.
