What became clear when the government imposed curfew?

Correct answer: The government wanted to suppress the movement

The governing historical concept is the use of coercive state measures during a period of unrest. A curfew restricts people from moving freely and gathering in public places. When imposed in the context of a movement or protest, it indicates that the authorities were attempting to control, weaken, or suppress the mobilisation rather than encouraging it. Thus option A is correct. The measure does not prove that land was distributed, that a war had been won, or that the Soviet Union had been formed. Those alternatives describe unrelated political or military developments. The question asks what the government’s action revealed about its intention, so the answer should identify repression or suppression of the movement.
