Two statements are given, one is labelled as Assertion (A) and the other as Reason (R):
Assertion (A): Age structure is independent on development and average life expectancy.
Reason (R): Poor health facilities and prevalence of diseases and other factors lowers life expectancy.

(A) is false but (R) is true

Assertion is incorrect. Age structure is dependent (not independent) on development and average life expectancy. Age structure, which refers to the distribution of different age groups within a population, is directly influenced by development and average life expectancy. A higher average life expectancy, often associated with better healthcare, economic stability, and overall development, leads to a larger proportion of older individuals in the population. Conversely, lower life expectancy due to factors like poor health facilities or prevalent diseases results in a younger population profile.

Reason (R) is true: Lower life expectancy can indeed be caused by poor health facilities, widespread diseases, and other factors like malnutrition, violence, or environmental hazards. These elements affect overall health and mortality rates, impacting the age structure of the population.
