Answer 2

Answer:

3. Burning crackers

Explanation:

1. Due to plantation of trees along the road, the sounds emitted from the vehicles can be objected by the trees.

So, it helps in controlling the noise pollution

2. By using silencer in heavy vehicles, the sound emitted from the vehicles  engine can be reduced to much extent.

Hence, it helps in  reducing the noise pollution.

Henceforth, if we set up industries away from the residential areas we can decrease noise pollution.
