Why is population considered a resource rather than a burden?
A healthy, educated, and skilled population acts as human capital that drives economic growth and development, utilizing other natural resources effectively.
What is the difference between metallic and non-metallic roads?
Metallic roads are made of cement, concrete, or asphalt and are all-weather roads, whereas non-metallic roads are made of mud and gravel and are usually unusable during the rainy season.
