As Scientific Disciplines, Epidemiology and Demography Have Both Developed Through

As scientific disciplines, epidemiology and demography have both developed through collection of information in large scale, state-level societies. Given this fact,

A) Epidemiological studies tend to focus on epidemic diseases that spread quickly in settled societies.
B) Ethnographers working in small, isolated societies are better equipped to study the presence of endemic disease.
C) Cultural anthropologists working in small-scale, isolated communities would need to modify epidemiological approaches in ways that better suit that research setting.
D) Many medical anthropologists have promoted the concept of syndemic disease to combine the conditions of both large- and small-scale societies in their analyses.
E) Paleodemographers are unable to employ modern epidemiological techniques.
