Question

what was one major result of the 1905 revolution in russia?
o tsar nicholas ii gave up power.
o russia suffered heavy losses on the eastern front.
o lenin took control of the petrograd sovist.
o russian workers organized into soviets.

Explanation:

The 1905 Revolution in Russia led to the organization of Russian workers into soviets. Tsar Nicholas II did not give up power in 1905 (he abdicated in 1917). Russia's heavy losses on the Eastern Front were mainly during World War I (not directly a 1905 Revolution result). Lenin took control of the Petrograd Soviet during the 1917 Revolution, not in 1905.

Answer:

Russian workers organized into soviets.
