Why was dual power both an achievement and a crisis of the February Revolution?

Correct answer: It removed Tsarism but power was divided between two centres

Dual power described the coexistence of the Provisional Government and the Petrograd Soviet after the fall of Tsarism. It was an achievement because the old autocratic monarchy had been removed and representative bodies of workers and soldiers had gained political influence. At the same time, it was a crisis because authority was divided between two institutions with different social bases and priorities. Therefore option A gives both parts of the explanation. The arrangement did not restore unlimited Tsarist power, exclude ordinary people, or end the war immediately.
