Answer 1

Step-by-step explanation:

Bursting of firecrackers could be heard across Delhi and its neighbouring areas on Diwali night even though a ban was imposed on its sale and use in the national capital region in view of rising air pollution and COVID-19 pandemic.

Sparklers were seen lighting up the night sky while crackers went off on the ground in various areas.
