The length of human life; longevity usually refers to living past the estimated life expectancy or the average age of death. Which term is this describing?

• A. Life Expectancy
• B. Infant Mortality
• C. Globalization
• D. Longevity

Answer: (D)

Longevity is the length of a person’s life, especially when someone lives longer than the average or estimated life expectancy. The statement highlights living past the expected age, which is precisely what longevity describes. Life expectancy is a statistical average of how long people are expected to live based on current mortality patterns, not the actual length of an individual’s life. Infant mortality and globalization are unrelated to the concept of how long a person lives. So, longevity is the best fit.
