Which of the following statements best explains why Russia left World War I before it ended

Answer 1

Russia left World War I before it ended primarily due to the October Revolution in 1917, which led to the Bolsheviks coming to power and signing the Treaty of Brest-Litovsk with the Central Powers in March 1918. The Bolsheviks wanted to focus on consolidating their power and implementing their communist agenda, rather than continuing to fight a costly and unpopular war. Additionally, the Russian economy and military had been severely weakened by the war, making it difficult to sustain the conflict.
