Answer:
d. He formally recognized the Soviet Union in an effort to stimulate trade.
Explanation:
One of the ways in which Franklin D. Roosevelt removed himself from Herbert Hoover's precedent was by formally recognizing the Soviet Union. The United States had refused to recognize the country since the 1920s. However, Roosevelt attempted to normalize relationships with the nation. This served two purposes. First, Roosevelt wanted to open and stimulate trade relations. Second, Roosevelt wanted to renegotiate the Russian debt from World War I. However, neither objective was particularly successful.
