What does the Air Quality Index show?

Answer and explanation

Correct answer: Quality of air

The Air Quality Index, or AQI, is a public indicator of the condition of the air and the level of air pollution. It is calculated from measurements of pollutants such as particulate matter and certain gases, and a higher value generally means poorer air quality and greater health concern. Therefore, option C is correct because AQI communicates how clean or polluted the surrounding air is. Option A concerns water, option B concerns soil, and option D concerns a building; none of these is measured by AQI. The governing green-skills concept is monitoring pollution so that people can reduce exposure and support cleaner environmental practices.
