Question

what marked the end of the russian monarchy?
○ the russian civil war
○ the russian revolution
○ the tsar and his family’s move to siberia
○ the execution of the tsar and his family

Explanation:

The Russian Revolution (specifically the February Revolution in 1917) led to the abdication of Tsar Nicholas II, which marked the end of the Russian monarchy. The Russian Civil War happened after the monarchy ended. The tsar's family's move to Siberia and their execution were consequences of the revolution and the end of the monarchy, not the event that marked its end.

Answer:

B. the Russian Revolution
