Final answer:
Friedrich Engels described Manchester as an industrial city overwhelmed by pollution and poor living conditions, symbolic of the era's industrialization effects.
Step-by-step explanation:
Friedrich Engels spoke of the English city Manchester with a description that highlighted the impact of industrialization on the city's landscape, cleanliness, and living conditions. Engels detailed the overwhelming presence of smoke and pollution emerging from the iron-foundries and how it settled on the streets and buildings of Manchester. This portrayal serves as a powerful statement on the industrial development during the era and its effects on urban environments, where bounded districts within a city could contain immense poverty, neglect, and uninhabitability, juxtaposed with the city's status as a leading manufacturing hub.
