Which of the following best describes the advantage of the web of causation model in comparison with the epidemiological triangle model?
a. The web of causation model is easier to understand and use.
b. The web of causation model is more widely known and publicized.
c. The web of causation model is more recent and current.
d. The web of causation model shows the relationships among variables.
ANS: D

It is not easier to understand and use as it has more variables than the three (agent, host, and environment) in the epidemiological model.
