Answer:
The answer is: letter A. his policy of an action worsened the effects of the Great Depression on the population.
Explanation:
Herbert Hoover was the 31st President of the United States. Upon being elected, Hoover did not get himself involved with the central banking system of the USA (Federal Reserve System). Thus, this resulted to the Stock Market Crash of 1929. This condition dwindled into the Great Depression.
Hoover attempted to respond to the Stock Market Crash by raising the agricultural tariffs. This was a strategy meant to help the farmers from the crisis. This, however, led to the raising of the supplies' rates. Part of this was due to the non-involvement of Hoover with the congressional leaders in making a decision. The global trade then contracted, which worsened the economy.
Thus, this explains the answer.
