Do you like only one kind of taste or different ones? Why?
Jhoolan put a few drops of lemon juice in Jhumpa’s mouth. Do you think we can make out the taste with just a few drops?
If someone were to put a few seeds of saunf (aniseed) on your tongue, would you be able to tell with your eyes closed? How?
How did Jhumpa make out the fried fish? Can you guess the names of certain things only by their smell, without seeing or tasting them? What are these things?
Has anyone ever told you to hold your nose before taking a medicine? Why do you think they tell you to do this?

We like different kinds of tastes.
This is because if we keep eating food with similar taste, we will get bored of that taste very soon. Moreover, to stay healthy we need a diet with proper quantity of all kinds of food that have different tastes.
Jhumpa might have made out the fried fish by its smell.
There are several other things we can make out using their smell. Few of them are
(i) Halwa
(ii) Coffee
(iii) Jackfruit
(iv) Orange
(v)Sambar

Imagine you are eating something hard like a green guava. What kinds of changes take place in it – from the time you bite a piece and put it in your mouth to when you swallow it? Think what does the saliva in our mouth do?
Solution:
The process of chewing breaks down larger food particles into smaller ones. This has two advantages:
(i) Moistening of food that enables its easy swallowing
(ii) The process of chewing initiates the process of digestion in the mouth
