Answer to Question 1

Ans: C
Feedback:
The web of causation is an epidemiologic model that strongly emphasizes the concept of multiple causation while de-emphasizing the role of agents in explaining illness. The epidemiologic triad is the classic model based on the belief that health status is determined by the interaction of the characteristics of the host, agent, and environment, not by any single factor. The wheel of causation de-emphasizes the agent as the sole cause of disease while emphasizing the interplay of physical, biological, and social environments. Natural history is the course of a disease or condition from the onset to resolution.

Answer to Question 2

Ans: D
Feedback:
John Snow performed epidemiologic research on transmission of cholera using natural experiments, mapping, and rates. William Farr is considered the father of modern statistics. John Graunt analyzed weekly reports of births and deaths. Florence Nightingale used statistics to improve public health in England.
