Which doctrine aided Greece and Turkey by providing aid to resist communism?

• A. Containment
• B. Truman Doctrine
• C. Marshall Plan
• D. Korean War

Answer: (B)

The idea being tested is a direct U.S. pledge to help nations resisting communist pressure, not just a broad strategy or a rebuild program. The Truman Doctrine fits this precisely: announced in 1947, it stated that the United States would provide political, military, and economic aid to countries threatened by communism, with Greece and Turkey named as the first test cases. This policy aimed to stop the spread of Soviet influence by backing governments resisting subjugation, which is why it’s the best answer. By contrast, containment is the overall approach to stopping communism, the Marshall Plan focused on rebuilding Western Europe, and the Korean War was a conflict, not a doctrine.
