Final answer:
The Russian Revolution led to Russia's exit from WWI, allowing them to focus on internal affairs and consolidating Bolshevik power.
Step-by-step explanation:
The correct answer is: The Bolsheviks opposed Russia's involvement in WWI, so Russia exited the war early after the Russian Revolution.
After the Russian Revolution in 1917, the Bolsheviks took control of the government and they were against Russia's participation in WWI. As a result, they signed the Treaty of Brest-Litovsk in March 1918, effectively ending Russia's involvement in the war. This decision allowed Russia to focus on internal affairs and consolidate Bolshevik power.
By exiting the war, Russia's withdrawal had significant consequences for the other countries fighting in WWI. It led to the collapse of the Eastern Front and allowed Germany to transfer troops to the Western Front, prompting a series of offensives. Overall, the Russian Revolution played a major role in shaping the outcome of WWI.
