Answer:
A) the declining role of communism in the Soviet Union
Step-by-step explanation:
The Tiananmen Square protests and the fall of the Berlin Wall occurred in 1989, representing the impact of the declining role of communism in the Soviet Union. As communism was fading in the USSR, control of her outer boundaries diminished. Many Chinese students and educated elite believed this might lead to more western-style democratic processes. The wall fell in Germany, but the protests were squashed in China.
