Which doctrine stated that the United States would provide aid to free peoples resisting subjugation?

• A. Containment
• B. Truman Doctrine
• C. Marshall Plan
• D. Launch of Sputnik

Answer: (B)

The main idea tested is a policy pledge in which the United States promised to help nations resisting subjugation by communist forces. This was stated as the Truman Doctrine, announced in 1947, naming Greece and Turkey as key cases where the U.S. would provide political, military, and economic assistance to prevent Soviet influence from taking hold. It framed U.S. foreign policy around stopping the spread of communism and laid the groundwork for the broader strategy of containment that guided Cold War actions. The other options don’t fit this exact pledge: Containment is the overall strategy to stop expansion, not the specific promise to aid resisting nations; the Marshall Plan focused on rebuilding Western Europe’s economies to reduce susceptibility to communism, not on aiding resisting subjugation; launching Sputnik was a Soviet space achievement with no doctrine about aiding free peoples.
