Final answer:
The correct answers are options a,b, and c. Some reasons why resource-rich countries may not prosper include higher exports compared to imports and corruption, lack of technical knowledge, and lack of demand for resources.
Step-by-step explanation:
Reasons some resource-rich countries do not prosper
Higher exports as compared to imports and corruption: Resource-rich countries often rely heavily on exporting their resources, which can lead to imbalanced trade. This can result in economic instability and hinder overall prosperity. Additionally, corruption can siphon off wealth and hinder economic growth.
Lack of technical knowledge: Resource-rich countries may not have the necessary technical knowledge and expertise to effectively utilize their resources. Without the skills to extract, refine, and develop value-added products from their resources, these countries may struggle to prosper.
Lack of demand: Even if a country has abundant resources, if there is no demand for those resources in the global market, the country may not be able to generate significant revenue or achieve prosperity.
