2. He assisted in developing NATO, which helped Western Europe rebuild after the war.
4.He created the Marshall Plan, which provided economic support for war-torn regions.
5.He helped stop the spread of communism in Western Europe.
Explanation:
These are all nonmilitary contributions of George C. Marshall after World War II. In this passage, we learn that Marshall developed a plan that was known as the "Marshall Plan." This provided economic support for war-torn regions. Thanks to this program, NATO was developed and Europe rebuilt. Moreover, this program helped stop the spread of communism in Western Europe.
2 and 4 are outlined in the passage as contributions of Marshall. As Secretary of State he assisted in the creation of the NATO treaty and economic programs to prop up European countries following WWI. It then can be argued that due to the economic programs offered by NATO and the Marshall Plan that Marshall also helped to prevent communism from spreading to economically fragile countries. The help of strong western nations also blocked the USSR's ability to assist and spread their doctrine.
