Answer:
These are the options that apply:
Differing political systems as well as disagreements over the rebuilding of Europe and Berlin
Mistrust between the Soviet Union and the Western democracies
The inclusion of China in the Security Council of the United Nations
Step-by-step explanation:
The Cold War primary motivation was an ideological battle between capitalism and socialism or communism. Capitalism was spearheaded by the United States and its allies, while socialism was spearheaded by the Soviet Union and its allies.
The Cold War began to erupt shortly after the end of World War II over disagreements about the rebuilding of Europe. The Soviet Union had effectively occupied most of Eastern Europe, and installed puppet governments there. The United States instead focused on Western Europe, giving European nations financial means for the rebuilt (the Marshall Plan).
There was also disagreement between the Soviet Union and the United States about the inclusion of China in the Security Council of the UN. The United States wanted China to be included because they believed that China would fight the Soviet Union, little they knew that Mao would be victorious in the Civil War, and turn the China into a Soviet ally.
