Biji Returned the Bread

Aman’s Biji went to the market to buy bread. The shop was very crowded. The shopkeeper picked up a packet of bread and gave it to Biji. She looked at it and returned it immediately.

Look at the picture of the bread packet here and guess why Biji returned it? How did she find that the bread had got spoilt?

Answer.

We can clearly see the green spots on the bread slices in the picture. This change in colour is an indication that the bread has got spoilt. Thus, Biji would have observed these green spots and returned it to the shopkeeper.
