Step 1
Identify the factors influencing life expectancy
Answer
Life expectancy is significantly influenced by various health indicators. Among these, morbidity rates (incidence of illness) and infant mortality rates (number of deaths in infants) play crucial roles. Assessing these options helps us understand their impact.
Step 2
Evaluate each option
Answer
-
High morbidity rates: This option suggests that a high level of sickness would adversely affect overall life expectancy, which typically does not contribute positively.
-
High infant mortality rates: High rates in this area negatively impact life expectancy as it indicates a higher likelihood of child deaths, thus lowering the average.
-
Low morbidity rates: This is favorable as it indicates a healthier population, contributing positively to life expectancy.
-
Low infant mortality rates: This option reflects a healthier society with better healthcare, significantly improving average life expectancy.
