Evaluate the drafted changes
The topic is very unique and refreshing, and it is very good choice, but you will still need to finish the lead section with a little background about COVID-19 and how the lockdown impacted the air quality.

The content is easy and clear to read and understand, but I would suggest to find more information on the air quality before the pandemic and compare the differences to emphasize the impact of lockdown on air quality. You can also provide some cities that have the most differences.

The one source listed is up-to-dated, but I would suggest to add some sources on explaining the pollutants, like particulate matter, nitrogen dioxide, etc. Then add the in-text citations using the tips we learned from Module 4.
