Sorry, but may you add the whole question :(
Lol maybe I might know it
It is best known as a Cold War foreign policy of the United States and its allies to prevent the spread of communism. As a component of the Cold War, this policy was a response to a series of moves by the Soviet Union to increase communist influence in Eastern Europe, China, Korea, Africa, Vietnam, and Latin America.
HOPE THIS HELPED!!! XD
Serf is the correct answer.
Under feudalism, serfs (also known as peasants) represented the lowest class in the system. Even though they were not slaves neither own the land the worked in, they were bound to it. Serfs were required to give a part of their harvest to the person who actually owned te land. In return, these serfs were able to keep their own subsistence and were protected against bandits, thieves and possible injustices.
