Answer: B - The "November Revolution," which occurred on the night of November 6-7, 1917, marks the Bolshevik takeover of the Russian government. The Czar had been removed in the spring, and Alexander Kerensky had become head of the emerging government. However, Kerensky had very little popular support, and World War I had exhausted the nation. Thus, when Lenin and the Bolsheviks decided to claim the government for themselves, they found little opposition and easily seized control of the government.
