How did Bolshevik victory in the Civil War affect the changes after October?

Correct answer: It preserved the new power and strengthened centralisation

The direct answer is A: Bolshevik victory preserved the new government and strengthened centralisation. After October, the Bolsheviks faced opponents in the Civil War, including anti-Bolshevik forces and foreign intervention. Winning the war enabled them to retain political power, control more territory and organise the state through a stronger central authority. The victory therefore helped turn the revolutionary takeover into a durable regime, although the war also encouraged emergency controls and reduced political pluralism. A is correct because it connects military victory with survival and state-building. B is wrong because the victory did not restore Tsarism; the Bolsheviks defeated forces associated with the old order. C is wrong because victory did not end all nationalisations; central state control remained important. D is wrong because the Constituent Assembly did not become supreme again; it had already been dissolved after conflict with the Bolsheviks. The question asks how victory affected the changes, so focus on consolidation rather than on an isolated battlefield fact. Memory cue: Civil War victory meant survival, control and stronger centralisation.
