Umesh's grandfather went to village to meet his old friend, after a long time.He found that his friend who once was a big landlord became very poor. Grandfather asked the reason of his poverty in spite of so much land he possessed.He told that his land is suitable for growing cotton and every his crop is devastated by insect attacks and he has been suffering heavy losses.Grandfather consoled him and advised him to grow BT cotton in his fields.

(i) What is BT Cotton?
(ii) How has it been developed?
(iii) How did grandfather help his friend in solving his financial problems?
