Answer :
One cause of the Cold War was the fact that the United States and the Soviet Union were both "A-superpowers competing for dominance in global affairs" although there were other causes as well.
The correct answer is A. Superpowers competing for dominance in global affairs
Explanation:
The Cold War was an indirect conflict between the U.S. and the Soviet Union after the Second World War, from 1947 to 1991. Each of the parts involved and its allies represented two different sides, the Soviet Union was led by the Communist Party, in opposition to the U.S. guided by capitalism and a two-party system. Although there multiple factors that lead to this conflict, one of the causes of the Cold War was that both nations became superpowers after the Second World War as they were considered military giants and thus wanted to control nuclear weapons, ideologies (communism vs capitalism), military power and the space race (a competence for spaceflight capability) among other global affairs. Thus, one of the causes was two superpower competing for dominating global affairs.
