A. In 1930, the US passed the Smoot-Hawley Tariff Act, which increased average import duties to an all-time high of 59 percent in an attempt to stimulate domestic employment.

B. The serious implications of the Great Depression were inevitable given the stock market crash. x

C. In the early 1930s, the US pursued contractionary fiscal and monetary policy.

D. In the mid-1930s, the international organization called GATT, the General Agreement on Tariffs and Trade, was created to stimulate international trade.
