AP PSC PAPERS : Group -I Mains Examination
1. Read the passage given below and answer the questions that follow. 2x10=20
Homi Bhabha felt that it was his duty to stay in India and build up schools comparable with those that other countries are fortunate in possessing. He set about this job very methodically. He knew there were several competent Indians scattered all over. A school of research was the thing; he knew that could bring them together. The result was the Tata Institute of Fundamental Research. Bhabha gathered young and talented scientists to work at the institute. Noted scholars from all over the world gave talks.
Scientists suspected that there was an unknown force working inside the nucleus of an atom. But Bhabha had the perception: “when nuclear energy has been successfully applied for power production, say, a couple of decades from now, India will not have to look abroad for experts.” Bhabha was appointed as the first Chairman of Atomic Energy Commission, which was established in 1948 under Department of Scientific Research. Later on, after creation of Department of Atomic Energy (abbreviated as DAE), the Commission was brought under the purview of DAE in 1958. Homi Bhabha knew Nehru well. Nehru gave him a free hand and funds without strings as well. Speed and efficiency were the hallmarks of all activities. A site was chosen in Trombay to house reactors and laboratories and to produce atomic power. People were trained and the infrastructure provided to satisfy the basics of atomic research.
The atomic energy network gradually extended. A heavy-water plant was set up at Nangal, a monazite plant at Alwaye; the Atomic Minerals Division set up its own plants where Uranium could be mined. Canada’s help was sought to build a reactor in Trombay. Bhabha thought that nuclear physics could lead to production of cheap electric power. One gram of uranium could provide power to Calcutta for twenty years. Besides, the atmosphere would be pollution free. However, the danger of radioactivity leakage should be guarded against. European scientists were skeptical about the peaceful uses of atomic energy nor were they sure how economical generating electricity would be. But Bhabha showed how nuclear power could compete with thermal power. The first power plant was set up at Tarapur to provide power to Maharastra and Gujarat – something that Bhabha did not live to see.
To have breeder reactors turn thorium into nuclear fuel was Bhabha’s fondest dream. Very soon India will be completely self-sufficient in nuclear fuel. It was Bhabha’s vision and organization that enabled India to enter the select nuclear club.

2. Read the passage given below and make a précis of it by reducing it to one thirds of its original length. Give an appropriate title to the passage. 15
The lion is the world’s second largest living cat after the tiger, and some of them weigh over 250 kg. At present it is found in Sub-Saharan Africa and Asia, with a small endangered population in northwest India. In historic times, it also used to be found in North Africa, Western Asia and the Middle East. About 10,000 years ago, the lion was the mammal with the largest population after humans and was widespread in most of Africa, Eurasia, and the Americas. Lions in the wild live for ten to fourteen years, but they can live up to twenty years in captivity. Their natural habitats are mainly savannas and grasslands, but they also live in the bushes and forests. Lions are more social than other cats, and live in groups. A pride of lions consists of a few adult males, cubs and female lions, which hunt for prey. Lions usually kill hoofed animals for food but they also feed on dead animals if necessary. Lions usually do not hunt humans, unless they turn maneaters.The species is now endangered with a possibly irreversible decrease of thirty to forty per cent over twenty years. It seems that the animals can survive only in reserves
and parks. The cause of this extinction could be the loss of their natural habitats and their conflicts with humans, who, for example, have kept lions as live exhibits since historic times. However, at the present, zoos are taking part in breeding programmes for Asiatic lions. The distinctive and well recognized image of the male lion with its mane is among the most common animal symbols. It has been found in caves dating from the Paleolithic period and was part of ancient and medieval cultures. The symbol is widely used in literature, art, flags and contemporary films. (300words)
