Answer 1

Explanation:

The lockdowns enforced due to the COVID-19 pandemic led to large improvement in air quality in India, say scientists who suggest that such interventions may be used as a possible emergency measure to combat severe air pollution episodes like those witnessed in Delhi-NCR region during the winter months.
