Answer to Question 1

ANS: B
Immunity refers to species-determined resistance to an infectious agent and is determined by the characteristics of the host. The agent is the infection that is causing the infection/disease. Envi-ronmental factors may influence the susceptibility of the host. The epidemiologic triad involves the interaction of the host, agent, and environment.

Answer to Question 2

ANS: B, D
Factors contributing to the development and application of epidemiologic methods in the twenti-eth century were: improved nutrition, new vaccines, better sanitation, the advent of antibiotics and chemotherapies, and declining infant and child mortality and birth rates. A rise in the stand-ard of living occurred for many following the Great Depression and World War II. The ad-vancements in medical technology have not influenced the examination of the epidemiology of various diseases.
