The correct answers to these open questions are the following.
Although there are no options attached, we can say the following.
What was the purpose of economic aid from the US after WWII?
The purpose of economic aid from the US after WWII was to rescue the economy of the western European countries that participated in World War II. The US came up with the Marshall Plan to help the economies of Western Europe after the war.
I consider the Marshall plan was successful in that it helped to recovery Western Europe after so much destruction provoked by World War II. The Marshall plan was crafted in 1948 by George Marshal, who was the Secretary of State of the United States. The plan allocated approximately $15 billion to reconstruct many places in Europe.
2. In what ways were the two main superpowers (US and USSR) tried to influence nations around the world?
On one hand, the Soviet Union tried to spread Communism around the world. On the other hand, the United States instilled the foreign policy of containment, trying to stop Communism.
Those were the conflictive Cold War years in which both superpowers competed in the arms race, the space race, and put the world on the brink of another world war during the tense moments of the Cuban Missile Crisis of October 1962.
