Hi,

Hope you are doing well!

1). Question:

Answer:

a. Urbanization

During the first half of the century, changes in the ability to avoid and withstand infectious diseases were the prime factors in reducing mortality. Infectious diseases were the leading cause of death in 1900, accounting for 32 percent of deaths. Pneumonia and influenza were the biggest killers. Therefore, improved nutrition and public health measures, particularly important for the young, were vastly more important in this period than medical interventions. Better nutrition allowed people to avoid contracting disease and to withstand disease once contracted; public health measures reduced the spread of disease.Increasingly, mortality reductions are attributed to medical care, including high tech medical treatment.
