Why was the joining of urban and rural discontent decisive in the Russian Revolution?

Correct answer: Because workers' industrial pressure and peasants' land demand together formed a broad social base

Urban workers and rural peasants had different immediate grievances, but their demands could reinforce one another. Workers protested against low wages, long hours, food shortages and political repression, while peasants wanted land and relief from the burdens of war and landlord control. Soldiers, many of whom came from peasant families, also became receptive to revolutionary appeals. When these urban and rural pressures converged, the government faced unrest across workplaces, the army and the countryside. Therefore option A is correct; the other options deny the documented hardships or reverse the direction of popular opposition.
