SAT Subject US History Practice Question 1037: Answer and Explanation
4. The Monroe Doctrine
A. was enforced by England.
B. created a sphere of influence for the United States in the Western Hemisphere.
C. expelled all European nations from the Western Hemisphere.
D. reiterated the U.S. policy of involvement in world affairs.
E. was part of the American System proposed by Henry Clay.
Correct Answer: B
The Monroe Doctrine of 1823 forbade future colonization in the Western Hemisphere and warned the European powers not to interfere in the affairs of the Americas. Thus, it created a sphere of influence for the United States in the Americas. Supported by England, the Monroe Doctrine required no enforcement. The colonies already held by the European nations in the Americas were not to be interfered with under the terms of the Monroe Doctrine, and it appeared to be more a policy of isolation than a policy of involvement. The American System proposed by Henry Clay was a vision for the United States in which the United States would become more self-sufficient, but this was not part of the Monroe Doctrine.
