The main difference between the plans of Columbus and da Gama mainly differ in the way they tried to reach the continent, while Columbus was going for a much riskier option and wanted to reach Asian through unexplored ocean by going in a westward direction, da Gama was going for a safer option by traveling near the continental mainlands and was going south to go around Africa and than eastward towards the already known direction for Asia. This lead to different results, Columbus unintentionally managed to discover a whole new world for the Europeans, while da Gama managed to open up a route towards Asia that was clear of any charges or passing through the waters of some empire.

Answer:
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.
