Why did industrialization bring new social problems in Russia?

Correct answer: Because the difficult condition of factory workers emerged

Industrialisation transformed Russia by expanding factories, towns, and the industrial working class. Although it increased production, many factory workers faced low wages, long hours, overcrowded housing, poor sanitation, and dangerous working conditions. These problems created dissatisfaction and encouraged workers to organise, strike, and demand political and economic reform. The issue was therefore not simply the existence of machines, but the unequal and harsh conditions of factory society. Option B is correct because it identifies the difficult condition of industrial workers as the new social problem. Option A is opposite to the historical situation, while C concerns politics and D has no connection with Russian industrialisation.
