According to the World Bank, a country with low or middle income is commonly referred to as a "developing country." These nations are characterized by their lower levels of income, infrastructure development, and overall economic stability compared to high-income countries.
Here's a breakdown to help you understand the options provided in the question:
1. First World: This term historically referred to countries aligned with NATO during the Cold War and does not specifically denote economic status.
2. Second World: This term historically referred to countries aligned with the Communist Bloc during the Cold War and also does not indicate economic status.
3. Third World: This term originally referred to countries that were non-aligned or neutral during the Cold War. Nowadays, it is often used to describe developing countries but can be considered outdated due to its Cold War origins.
4. Developing: This term is widely used today to describe countries with lower or middle incomes that are working towards economic progress and improved living standards.
In summary, the correct answer based on the World Bank's classification would be "developing" when referring to a country with low or middle income.
