After the Spanish-American War, the relationship between Cuba and the United States can be described as follows: A. The United States controlled many of the nation's key industries. B. The United States appointed a governor for the country. C. Cuba did not accept communism but maintained ties with the United States. D. Cuba and the United States did not agree to give aid to the Soviet Union.

A. The United States controlled many of the nation's key industries.

• After the Spanish-American War, which ended in 1898, Cuba was technically independent, but the United States exerted significant influence over the country. This influence was codified in the Platt Amendment, which was part of the Cuban Constitution until it was repealed in 1934.
• The amendment allowed the United States to intervene in Cuban affairs and established conditions for the U.S. to end its military occupation, including the right to lease or buy land for naval stations (which led to the Guantanamo Bay Naval Base). Moreover, American companies came to dominate many key industries in Cuba such as sugar and tobacco.

While other options might contain elements that are true in different time periods, they do not accurately describe the aftermath of the Spanish-American War.
