Question

Boojho and Paheli were eating their food hurriedly so that they could go out and play during the recess. Suddenly, Boojho started coughing violently. Think of the reasons why he was coughing

Answer 1

he was eating vastly big bites

Answer 2

he must be coughing because of the mis functioning of epiglottis ( which covers the wind pipe when a person swallows food ).
The food he swallowed must have entered the wind pipe as he was swallowing hurriedly. That's why he started choking so as to expell the food out of the wind pipe...
