a) in 1930 over 1,350 banks closed and customers lost all their savings.

b) the unemployment rate in 1929 was 3.2% and by 1933 there was a 25% unemployment rate.

c) in 1920 a bushel of wheat sold for $2.94, in 1929 it sold for $1.00 and by 1932 a bushel sold for .30 cents.

d) the stock market's dow average dropped over 23% over a two day period in october of 1929 and lost 90% of it's value by 1932.

The correct answer is letter C.

From the beggining of the 20th century to the start of World War II there was a huge rollercoaster happening in the wheat business.

The prices climbed sharply before World War I and peaked after its end. European farm production was able to guarantee years of low prices and the American agriculture was deemed to a great depression even before the stock market crash of 1929. The prices climbed in the mid-1930s and then plunged again. Not until World War II did America sustained increases in price and demand.
