Answer 2

Answer:

The grains and pulses that we buy from the market may contain undesirable components like small stones. These components look very different from the food grains. They are of different sizes and colours. So, they can be spotted easily. Such undesirable components can be removed by hand picking. Hand it means to take out by hand.

It is a convenient method of separating only when:

• the size, shape or colour of the unwanted substance is different from that of the useful one,
• the quantity of the mixture is small and
• the unwanted substance is present in small quantities.
