Answer:
Right answer:
They were both intended to stop the spread of communism in Europe.
Explanation:
The Cold War started in 1947. President Harry Truman announced that the United States would aid any foreign nation under the threat of domestic subversion or an external threat to its political order by economic, military and political means. In practice, that meant support to fight against communist insurgency or against the threat of a Soviet invasion in Europe. This is what we know as the Truman Doctrine.
The Marshall Plan provided over $15 billion in aid to Western European countries. It helped the recovery of those economies ravaged by WWII. Building prosperity in Europe was also seen as a way to reduce the likelihood of a communist takeover in those countries, too.
So, both the Marshall Plan and the Truman Doctrine had as one of their main goals to put barriers to the spread of communism.
