22. Doc. #12 is telling us about the urban life in the 19th century is that, it’s a town with machinery which represents there were factories, and farms. Tall chimneys representing big farm houses. The bricks meaning that they were worn out and it the houses and buildings were mostly made out of brick.
23. Negative effects would be at the end where it says “interminable serpents of smoke trailed themselves for ever and ever” and “river that ran purple with ill- smelling dye...” meaning that there was pollution due to the factories.
hope this helps
