Why was 1989 a pivotal year in world history? (1 point)

• The Tiananmen Square protests were successful.
• Vietnam invaded and took over Cambodia.
• Communism started to decline and the Berlin Wall came down.
• Putin rose to power in Russia and took over.

• Communism started to decline and the Berlin Wall came down.

This is the correct answer. The events of 1989 marked a significant turning point in world history as communism started to decline and ultimately collapse in Eastern Europe. The fall of the Berlin Wall in November 1989 symbolized the end of the Cold War division between East and West, and set in motion a series of events that led to the reunification of Germany and the eventual disintegration of the Soviet Union. This marked a shift in global politics and had far-reaching implications for the balance of power and the structure of the international system.
