[Q]: Question: Are both of the band members who put out the album "Flags" still alive? Passage:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

[Q]: Question: How old was Madonna when she released her second studio album? Passage:American entertainer Madonna has worked in twenty-six feature films (twenty-one as an actress), ten short films, three theatrical plays, ten television episodes, and appeared in sixteen commercials. at age 16, she auditioned in a high-school short movie called "the egg" where she played a teenage sunbather relaxing at a patio eating raw eggs. In 1979, she made her acting debut in the low-budget feature A Certain Sacrifice. Its commercial release in 1985 coincided with the success of her second studio album, Like a Virgin. That same year, she made a cameo appearance as a club singer in the film Vision Quest; she also garnered commercial and critical success for the title role in Susan Seidelman's Desperately Seeking Susan. Madonna followed it with a leading role in the adventure drama Shanghai Surprise (1986), with her then-husband, actor Sean Penn. The film was panned by critics, and Madonna received her first Golden Raspberry Award for Worst Actress. Her next films such as Who's That Girl (1987) and Bloodhounds of Broadway (1989) were critical and commercial failures. In 1986, she made her theatrical debut in David Rabe's Goose and Tom-Tom and her first commercial for Mitsubishi in Japan. She starred in the 1989 commercial for Pepsi-Cola alongside her song "Like a Prayer". Due to the controversy surrounding the song's music video, the commercial was revoked and her contract with Pepsi-Cola was cancelled.

[Q]: 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.
