Answer:
2. The Fall of the Berlin Wall was a symbolic end to the cold war, etc.
Step-by-step explanation:
On the East Berlin side, they are communists. The West Berlin side, people didn't know how to react when the wall was being destroyed down because they were all used to avoiding communists their whole life. Ronald Reagan made a speech about the wall saying, "Tear This Wall Down!" This speech was for Mikhail Gorbachev, and he agreed to tear down the wall to finalize the freedom between both sides. The Cold War has been going on for ages as well, so this major event turned history around and made the Cold War finally end in 1989.
