the stock market crash of 1929 was a direct result of\no a lack of confidence in the economy.\no a mass practice of buying goods and services on credit.\no a surge of growth in the economy.\no an underproduction of goods in farming and manufacturing.
Answer
Brief Explanations:
The 1929 stock - market crash was due to over - speculation and a lack of real economic foundation. Buying on credit led to an artificial inflation of asset prices. When the bubble burst, it was a result of the unsustainable mass practice of buying goods and services on credit which also affected stock values. A lack of confidence was a consequence rather than a direct cause. Growth surges don't typically cause crashes immediately. Underproduction was not the main factor here.
Answer:
a mass practice of buying goods and services on credit.
