Which city faced severe air pollution issues leading to a significant smog event in 1873?

• A. New York
• B. London
• C. Chicago
• D. Paris

Answer: (B)

London is recognized for experiencing severe air pollution issues during the Industrial Revolution, with a notable smog event occurring in 1873. The combination of rapid industrial growth, which included the use of coal for power, and the city's geography, which trapped pollutants, led to significant air quality problems. The infamous thick fogs that resulted from industrial emissions became a defining characteristic of London during this period, contributing to public health crises and prompting awareness of environmental issues related to industrialization.

In contrast, while cities like New York, Chicago, and Paris also faced challenges related to industrial pollution, the specific smog event in 1873 is closely associated with London and its unique conditions at the time.
