Answer:
D: prosperous
Explanation:
The US economy experienced the greatest economic growth of all the times, since the demand for consumer goods made in America rose greatly the years to follow the end of World War II.
The products were demanded worlwide, the postwar years 1954-1960 made America be the richest economy in the world.
American products were introduced in European markets as well, and the Great Depression years were quickly forgotten. The American style of life was promoted in the coming of the new World shaped by the Us and the West.
Ever since the war, the involvement in the war made production rates go the highest levels historically. American factories supported the effort abroad and this caused a unemployment rate to drop to the lowest level.
The war brought the return of prosperity, and in the postwar period the United States consolidated its position as the world's richest country.
Further US actions in China in the Cold war increased the US predominance in markets. An ever increased demand for products would never be experienced again.
