Why can the Treaty of Brest-Litovsk be called a difficult test of Bolshevik peace policy?

Correct answer: Russia had to accept territorial loss in order to obtain peace

The Bolsheviks had promised to end the war, and the Treaty of Brest-Litovsk achieved that immediate objective. Yet peace was not obtained on equal or favourable terms. Russia was forced to give up extensive territories and accept a serious reduction of its power in order to stop fighting Germany. This created a difficult choice: preserve the new revolutionary government through peace, or continue the war and risk further destruction. Option A expresses this central compromise. Options B, C and D are false because Russia did not rule Germany, the Tsar did not return, and the treaty was made by the Bolshevik government rather than by the Constituent Assembly.
