Mortality is based on a large risk pool of
A. income and time
B. geographic area and time
C. people and time Correct
D. family history and hobbies
Rationale: Mortality is fundamentally linked to a large risk pool of individuals over time. This allows for a more accurate assessment of life expectancy and risk factors associated with death.
Option A, income and time, overlooks the broader demographic factors influencing mortality. Option B, geographic area and time, while relevant, fails to encompass the diversity of individuals within a population. Option D, family history and hobbies, focuses too narrowly on personal traits and does not represent the larger population dynamics necessary for effective mortality analysis. Hence, understanding mortality requires a comprehensive view of people across time.
