Answer:
An individual homeowner.
Step-by-step explanation:
The question asks who would not be responsible for monitoring air quality. Individuals with no expertise have no responsibility to monitor air quality. They may not have the education on air quality or proper tools for it, and neither do they need to. On the other hand, government authorities can have the responsibility of monitoring public safety and environment quality.
"An individual homeowner" was correct on the FLVS quiz, likely due to the reasons stated above.
