Standard of living via GDP per capita comparison

Steps:

• Define standard of living as economic well-being, primarily measured by GDP per capita.
• Recall GDP per capita values: Bangladesh (~$2,500), Bhutan (~$3,500), Botswana (~$7,000), Brunei (~$30,000).
• Compare values to identify the highest indicator of wealth and services access.
• Select Brunei as it exceeds others by a wide margin.

Why D is correct:

• Brunei tops GDP per capita rankings due to vast oil and gas reserves, per World Bank economic formulas.

Why the others are wrong:

• A. Bangladesh has low GDP per capita from overpopulation and agriculture dependence.
• B. Bhutan prioritizes Gross National Happiness but has modest GDP per capita from limited industry.
• C. Botswana benefits from diamonds yet has lower GDP per capita than Brunei's oil wealth.

Final answer: D
