What was the soviet response to the western alliance known as nato?
a. the berlin blockade
b. the warsaw pact
c. the eastern bloc
d. the satellite treaty

The best answer is B.

The Warsaw pact is the name commonly given to the treaty between Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, Romania and the Soviet Union which was signed in Poland in 1955 and was officially called The Treaty of friendship, Co-operation and Mutual Assistance. It was called the Warsaw pact because it was signed in Warsaw.

It was a response to the formation (by western allies) of  the North Atlantic Treaty Organization (NATO). West Germany was allowed to join NATO and was allowed to re- militarize and thus the Soviets saw this as a potential threat.

nothing certain is known about what happened, but it seems that the country declined gradually, perhaps due to bad government, or, more likely, due to a series of bad harvests, which resulted in widespread and recurrent famine.
