Question

which development resulted in the spread of disease and increased mortality rates during the industrial revolution?
a. overcrowding in cities
b. development of pasteurization
c. increased division between social classes
d. emigration to the united states

Explanation:

During the Industrial Revolution, overcrowding in cities led to poor living conditions. This made it easier for diseases to spread as people were in close proximity. For example, lack of proper sanitation in crowded urban areas contributed to higher mortality rates. Pasteurization (B) was a later development that helped prevent disease. The division between social classes (C) was more about economic and social status rather than directly causing disease spread. Emigration (D) was a movement of people but not the main cause of disease spread and increased mortality during the Industrial Revolution.

Answer:

A. Overcrowding in cities
