Answer:
B
Explanation:
The Cold War is called the Cold War because the United States and the USSR never fought each other directly.
Instead, they fought indirectly through proxy wars like the Vietnam and Korean War. Basically, they sent money and help to one side that was fighting. For example, in the Korean War, the US helped South Korea, because they were against Communism, and the USSR aided North Korea, since they were for Communism.
So, the correct answer is B: indirect.
They knew how to read and write , they basically taught the whole world that and they wrote events in their books. If these books didn't exist we wouldn't know what it was like back then.
