Answer:
It must be remembered that from 1929, and all throughout the 1930´s, one of the major economic issues caused by the Great Depression was the sudden plummet of prices in all areas of the economy. Agriculture was not immune to this collapse and farm products were priced too low, with a surpluss in some of the crops and with people still being unable to afford those products.
As such, in 1933, Congress passed the Agricultural Adjustment Act, as part of President Franklin D. Roosevelt´s New Deal programs. This law established that farmers whose crops were in surpluss production would be given governmental subsidies in return for them limiting the production of said crop. The attempt was to bring the prices a bit higher overall for farmers. This law was later brought down by the Supreme Court in 1936 and replaced by a modified version.
So, the correct answer to your question, would be: In the 1930´s, government agricultural programs focused on limiting production of certain crops that were in oversupply in order to: Raise the price of farms products.
