Explanation: This question refers to the Marshall Plan which was put in place in 1948 to help relieve the effects of World War II in some parts of Europe. It also had its own agenda of putting an end to communism.

The plan distributed aid to 16 countries including Britain and was up to a value of 5% of the GDP of the U.S. The recipients of the aid did not have to repay but some paid at different points especially, the cost of administering the funds.
