Why are the 1920s characterized as a decade of major economic change?

I have two possible answers for you. :)

The 1920s was a decade of hope for the Americans.  During this period, the standard of living improved as automobiles, trains and other new modes of affordable transportation gave rise to the suburbs. People were more relaxed and wanted to enjoy life as the economy was.

The 1920's was characterized as a decade of economic prosperity for Americans. Many American citizens invested their money in the Stock Market and were able to make a significant profit off of their investments. The Stock Market success resulted in millions of Americans buying stock on margin. Buying on margin allowed individuals to put 10% of the price of a stock as a down payment while borrowing 90% of the value of the stock from the bank. Banks at this time had thousands, possible millions, of these types of loans available for citizens. This system allowed citizens to have more currency on them, resulting in them spending it on luxury items like stoves, cars, ovens, etc.

Good luck!!

In the 1920s, more Americans than ever had begun living in cities instead of on farms. The nation's wealth doubled at this time, causing people to get swept up in a "consumer society" that helped the economy to grow abundantly.

because its important to learn about other countries and how high tech they are compared to us. also its good to learn about other cultures and how ours differs and in common also we need to learn about companies that we still buy since they ship it here.

the correct answer is a) egypt and china.

egypt and china are two of the world’s oldest civilizations known by man. both ancient empires have left a great historic and cultural legacy to the world through archeology. both civilzations developed complex social relations, had deep religious beliefs, had dominion of agriculture and left writing records to understand their customs and culture.

among the requirements to consider a civilization, we find urbanization, writing records, a place of residence, agriculture methods, technological specialization, means of transportation, currency, population density, social stratification, and political integration.
