Answer 1

Answer:

Hand-picking is a method of separation by which impurities that are different from the useful material in a mixture are hand-picked and removed. For example, rice, wheat, pulses, etc., contain impurities such as small stones or unwanted grains. These impurities look different from the useful material and are easily hand-picked and removed.
