The correct answers are B and E, since both fascism and communism spread worldwide as a result of the political and economic consequences of the Great Depression.
Fascism is an ideology, a political movement and a type of State of totalitarian and undemocratic character; created by the Italian Benito Mussolini, spread in interwar Europe from 1918 to 1939 as a result of the economic and social crises that hit Italy after the First World War, including among those the Great Depression.
Communism also expanded as a consequence of this crisis. Marxist economic theory had been developing since the middle of the 19th century, but since the Russian Revolution it had an effective application. At the outbreak of the Great Depression, Russia was not affected due to its policies of strong market control, so the world saw communism as an alternative to the capitalism, able to avoid future economic crises.
A and B is out because these undoubtedly are unique Chinese achievements. So is D. The Chinese are infamous for these things. Other achievements include gunpowder, fireworks, ect.
C is basically the answer because the chinese aren't the only race or country to do so. Many people have done it in the past before them and present in the terms of civilization. It isn't simply uniquely or originally from them.
