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.

Question: Was Carlos Manuel still alive when Batista was elected President of Cuba? Passage:Fulgencio Batista y Zaldívar (; ; born Rubén Zaldívar; January 16, 1901 – August 6, 1973) was a Cuban military officer and politician who served as the elected President of Cuba from 1940 to 1944, and as its U.S.-backed military dictator from 1952 to 1959, before being overthrown during the Cuban Revolution. Batista initially rose to power as part of the 1933 Revolt of the Sergeants, which overthrew the provisional government of Carlos Manuel de Céspedes y Quesada. He then appointed himself chief of the armed forces, with the rank of colonel, and effectively controlled the five-member "pentarchy" that functioned as the collective head of state. He maintained this control through a string of puppet presidents until 1940, when he was himself elected President of Cuba on a populist platform. He then instated the 1940 Constitution of Cuba and served until 1944. After finishing his term he lived in Florida, returning to Cuba to run for president in 1952. Facing certain electoral defeat, he led a military coup against President Carlos Prío Socarrás that preempted the election.

Question: Of the two films produced by a Bob, which of the Bobs were older? Passage:Cantor appears in caricature form in numerous Looney Tunes cartoons produced for Warner Bros., although he was often voiced by an imitator. Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935). Eddie Cantor is one of the four "down on their luck" stars (along with Bing Crosby, Al Jolson, and Jack Benny) snubbed by Elmer Fudd in What’s Up, Doc? (Bob McKimson, 1950). In Farm Frolics (Bob Clampett, 1941), a horse, asked by the narrator to "do a canter", promptly launches into a singing, dancing, eye-rolling impression. The Cantor gag that got the most mileage, however, was his oft-repeated wish for a son after five famous daughters. Slap-Happy Pappy (Clampett, 1940) features an "Eddie Cackler" rooster that wants a boy, to little avail. Other references can be found in Baby Bottleneck (Clampett, 1946) and Circus Today (Tex Avery, 1940). In Merrie Melodies, The Coo-Coo Nut Grove Cantor's many daughters are referenced by a group of singing quintuplet girls. In Porky’s Naughty Nephew (Clampett, 1938) a swimming Cantor gleefully adopts a "buoy". An animated Cantor also appears prominently in Walt Disney's "Mother Goose Goes Hollywood" (Wilfred Jackson, 1938) as Little Jack Horner, who sings "Sing a Song of Sixpence".
