The correct answer is A. In the 1950s and 1960s, the USSR controlled Eastern European nations via a number of methods, including establishing puppet governments and using force to crush any dissent or opposition to communist rule.

Explanation:

At the beginning of the Cold War, the Soviet Union established a series of satellite states with related governments indirectly controlled by the Soviet government. This set of countries was called the Eastern Bloc, and were bound militarily via the Warsaw Pact.

In addition to the Soviet Union, the Eastern Bloc consisted of Hungary, Romania, Bulgaria, Czechoslovakia, Poland and the German Democratic Republic (GDR). Sometimes Yugoslavia and Albania are also included in the Eastern bloc.

In the Eastern European areas that fell into the sphere of influence of the Communist Soviet Union after the Second World War, the then leader Stalin brought the Communists to power via coups. He wanted a chain of satellite states that would take the first blows in the event of foreign aggression.
