Which statement best summarizes the relationship between air quality and economic development?

The statement that air quality is generally better in developed richer countries compared to fast-developing poorer countries captures a critical understanding of how economic development correlates with environmental conditions. In wealthier nations, there is often greater access to technology that reduces emissions, stricter environmental regulations, and more resources allocated to maintaining cleaner air. Developed countries may also benefit from better infrastructure and public awareness about air pollution, which can lead to proactive measures to protect air quality.

In contrast, fast-developing countries may prioritize economic growth and industrialization, sometimes at the cost of environmental health. As these nations rapidly industrialize, they often experience increased emissions and pollution levels, leading to poorer air quality. Over time, many of these countries may recognize the need to address air quality issues, but in the initial stages of development, environmental concerns can be overshadowed by economic goals.

This relationship underscores the complex interplay between a nation's level of development and its environmental policies and practices. Thus, the correct statement reflects a common pattern observed in various regions around the world, noting that as countries become wealthier, they tend to improve their air quality due to better regulations and resources aimed at environmental protection.
