Answer: C. losing control over a significant amount of territory
Step-by-step explanation:
Russia was in the midst of a social disorder. The population demanded improvements in the quality of life, reduction of the tax rates and the exit of the country of the war because the maintenance of Russia in the war brought burdens for the population. One of the first measures stipulated by the Bolshevik leaders was to amnesty the exiles and withdraw contingents of Russian soldiers from the World War I. In this way, Russia withdrew from the war because of the enormous internal political problems. Shortly after the withdrawal of Socialist Russia from the war, its main leader, Lenin, signed with Germany a Peace Treaty between nations. The Treaty was called Brest-Litovsk (1918). With it, Russia lost several territories to Germany, such as Estonia, Lithuania, Ukraine, and Finland.
Russia's withdrawal from World War One anchored Germany from forces. Several territories were free for the displacement of the German troops, allowing the Germans an optimistic climate, that is, Germany reassessed the belief in the victory during the World War I.
