The correct answer is A. Truman fired MacArthur to preserve civilian control of the military.
Explanation:
After the invasion of North Korean troops into South Korea on June 25, 1950, MacArthur was given command of the international troops with a UN mandate, which he led to their first success when they landed at Incheon. In the course of the war and in the face of the deployment of Chinese volunteers and soldiers, he vehemently campaigned for the use of nuclear weapons in 49 North Korean cities and the expansion of the conflict into the People's Republic of China. President Harry S. Truman rejected these special requests on several occasions and finally dismissed MacArthur from his post on April 11, 1951 because of his continued and partly public urge. This decision led to violent protests in Congress and public demonstrations for MacArthur. Seven million people are said to have participated in a parade in New York. Public opinion saw MacArthur as a great war hero, while President Truman was largely unpopular.
There was new music, such as jazz and the blues. New churches and religious customs came north. There was different food and spoken dialect. Celebrations from their cultures came along with new neighborhoods. Finally, newspapers and journals had more of an impact.
