Answer:
On the night of November 9, 1989, the Berlin Wall—the most potent symbol of the cold-war division of Europe—came down. Earlier that day, the Communist authorities of the German Democratic Republic had announced the removal of travel restrictions to democratic West Berlin. Thousands of East Germans streamed into the West, and in the course of the night, celebrants on both sides of the wall began to tear it down.
The collapse of the Berlin Wall was the culminating point of the revolutionary changes sweeping East Central Europe in 1989. Throughout the Soviet bloc, reformers assumed power and ended over 40 years of dictatorial Communist rule. The reform movement that ended communism in East Central Europe began in Poland. Solidarity, an anti-Communist trade union and social movement, had forced Poland’s Communist government to recognize it in 1980 through a wave of strikes that gained international attention. In 1981, Poland’s Communist authorities, under pressure from Moscow, declared martial law, arrested Solidarity’s leaders, and banned the democratic trade union. The ban did not bring an end to Solidarity. The movement simply went underground, and the rebellious Poles organized their own civil society, separate from the Communist government and its edicts.

To gain wealth, power, and to get profit from trading, such as furs and other goods.
The correct answer is D. In both regions, Mongols allowed the previous administrators to continue to rule.
In both Persia and Russia, the Mongols had a regional governor, and to help them they recruited staff among the local population, they usually recruited people that came from lettered families and by hereditary basis. Historians have pointed out that Russians were trained by the Mongols to take orders, to pay taxes and to supply soldiers without delay, future czars also used the same techniques later on.
This caused the population to feel “part of the power” and this way they would be against a revolt for example. It was also a way of being closer to the population by taking some of them to work with the new “government”.
