How did the Petrograd Soviet turn workers and soldiers into a political force?

Correct answer: By organising them in a common representative council

The Petrograd Soviet became important because it brought workers and soldiers together in one representative body. Instead of remaining separate groups with limited influence, they could choose representatives, discuss urgent issues, and express their common demands. This gave ordinary people an organised political voice during the crisis of 1917. The Soviet therefore represented popular participation rather than rule by the Tsar or by a small privileged group.

The correct choice is A because it describes this process of organisation in a common representative council. Sending people to villages would not create a political institution, and making them the Tsar’s private army would strengthen the old regime. Removing them from politics would have the opposite effect. The important idea is that a scattered mass became a coordinated political force through representation.
