Answer 1

Dear Student,

Change in season is directly related to air pollution. During winter the pollutant in air combines with fog to form smog.
On the other hand air pollutants gets washed off with rain and thus the air becomes free from pollutants during monsoon.

Respiratory diseases are more common to children from low socio-economic status due to various reasons like:
1. Poor nutrition
2. Unhygienic condition and poor sanitation
3. Inability to afford vaccines and medical treatments.
