Why are the dates from 22 to 27 February important in studying the February Revolution?

Correct answer: In these days the movement grew from lockout to Soviet formation

The dates 22–27 February, according to the Russian calendar used at the time, mark the rapid escalation of the February Revolution in Petrograd. What began with industrial unrest and a lockout developed into strikes, women’s demonstrations for bread, mass street protests, and the defection of soldiers. By the end of this sequence, representatives formed the Petrograd Soviet, while the authority of the Tsarist government was collapsing. Option A is correct because it captures the progression from labour conflict to an organised revolutionary political body. The USSR was created later, Brest-Litovsk was signed in 1918, and the Bolsheviks seized power in the October Revolution, so options B, C, and D refer to different events or periods.
