He managed to dig only three wells and had to spent an enormous amount of time teaching the villagers to use pure water in place of contaminated water. There might have been only three wells but they gave the engineer a great feeling of achievement. Charles Darwin has shown that given enough time, small and gradual causes can produce large and radical changes. His last book was in fact on earthworms. He was preoccupied with the theme for forty years. He has shown that on every acre of the chalk hills near Down (U.K) worms brought up eighteen tons of earth annually. What a stupendous achievement for the small and insignificant earthworm!Even the dullest of men is a million times more creative and productive than the earthworm.

Even to try to tell you the story of my difficulties would fill up the whole of your valuable paper. It is a tale of misery and woe. The difficulties may well be likened to the heads of Ravana—the giant of the second great Hindu epic. Ramayana, whom Rama, the hero fought and ultimately defeated—which were many , and which were sooner chopped off than replaced. They may be divided chiefly under four heads, viz, money, consent of my elders, separation from relations and caste restrictions. First then, to money. Though my father was the Prime Minister of more than one native state, he never hoarded money. He spent all that he earned in the charity and the education and marriages of his children, so we were practically left with out much cash. He left some property, and that was all. When asked why he did not collect money and set it aside for his children, he used to say that his children represented his wealth, and if he hoarded much money he would spoil them. So then, money was not a small difficulty in my way. I tried for some state scholarship but failed. At one place, I was asked to prove my worth by graduating and then expect it. Experience teaches me that the gentleman who said so was right. Nothing daunted me. I requested my eldest brother to devote all the money that was left to my education in England. Now complete the following: (5)

a. The writer had no __________ to go to England. b. He had to get the consent of ____________. c. He had to ____________ from relations. d. He _____________ to get some scholarship but failed. e. He had to ask his __________ to help him because his father had left him no money.
