The answer that most accurately compares how international events affected the responses of East Germany's and China's governments to the protests of 1989 is:
The governments of both East Germany and China curtailed civil liberties and became less democratic following the protests of 1989, making both countries exceptions to the larger global trend of collapsing communist rule.
This answer acknowledges that both countries responded to the protests by tightening control and limiting democratic processes, in contrast to the broader international trends where many communist governments were collapsing or reforming.
