Explanation:

After the October Revolution, the Bolsheviks (led by Lenin) took power. One of their actions was to end Russia's participation in World War I. Lenin was not exiled after the October Revolution (he was a key figure in it). The protests about food and coal shortages were more related to the February Revolution. Karl Marx created his principles long before the October Revolution (in the 19th century).

Answer:

The Bolsheviks ended Russia’s involvement in World War I.
