Why is the layout of Petrograd important for understanding the February Revolution?

Correct answer: It shows the distance between workers' areas and centres of power

Direct answer: Option A, it shows the distance between workers’ areas and centres of power. A city’s physical layout helps us understand how a political movement travels. Petrograd contained industrial and workers’ districts as well as important government buildings and centres of authority. If workers gathered in their own areas and then moved toward bridges, major streets or government centres, the map showed how local economic protest could become a citywide political challenge. The layout also helps explain communication, crowd movement and the spread of strikes. Option A is correct. Option B is wrong because the map was not merely measuring a river. Option C is wrong because its purpose was not to locate a war treaty. Option D is wrong because it did not count peasant villages. Memory cue: in history, a map can explain power, movement and protest—not just physical land.
