Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.

ANSWER

Read the passage given below: The seasonal problem of water taps running dry is plaguing most of our major cities. With the bigger rivers flowing in trickles and ponds and wells reduced to clay pits, village women in remote areas have to fetch every drop of water for drinking, cooking , washing and so on, across large distances. This has only worsened a perennial problem, that of widespread pollution of water, rendering it unfit for human consumption. The monsoons and the attendant floods will not solve this problem. The Delhi Administration is seriously worried about the threat to civic health posed by the polluted waters of the Yamuna. Two main tanks are to be set up to treat sewage. At present, only 60 per cent of the 200 million gallons of the city’s sewage receives any kind of treatment before it is dumped into the river which supplies water not only to this city but to innumerable towns and villages downstream. The Ganga, the Yamuna, the Kaveri, in fact all our important rivers serving many urban conglomerations, are fast becoming a major source of diseases. A comprehensive bill introduced in the Parliament recently, envisages the setting up of central and state boards for the prevention and control of water pollution. But it will obviously take some time before legislation is passed and effectively implemented. Meanwhile the problem continues to swell. According to a survey of eight dwelling countries conducted a couple of years ago, 90 per cent of all child deaths were due to water borne diseases. It is the same unchanged story today. In a country like India, a burgeoning population continuing to use the open countryside as a lavatory means that with every dust storm and rain, human excreta laden with germs and parasites find their way to ponds, shallow wells and even the streams and rivers. Only 18 per cent of the rural folk have access to potable water. A new threat that has already assumed alarming proportions is form industrial waste which is generally dumped untreated into the nearest river. For instance, for every kilogram of process hide, 30-40 litres of foul smelling waste water has to be disposed off. There are at least 900 licensed tanneries in the organized sector. Putrefied paper and jute waste, metallic waste from straw board and textile, sulphur, ammonia, urea metallic salts and corrosive acids all find their way to the river of India. It is important not only to make a new laws to ensure the urity of water, but also to realize the urgency of implementing them ruthlessle, if we are to avoid a national health disaster cutting across the barrier between towns and countryside. On the basis of your understanding of the oassage, answer the questions by choosing the correct options (any eight out of the ten) Q.1 The most appropriate title for the passage is: A. The Inevitable Evil of Pollution B. Water Scarcity C. Pollution D. Tackling Water Pollution Q.2 The bill mentioned in the passage: A. Creates financial scope for water treatment facilities. B. creates Central and State Boards for control of water pollution. C. looks into the effective implementation of legislation. D. looks into the proper treatment of water bodies. Q.3 According to the passage, what can ut through the barrier between town and villages? A. Number of child deaths B. Water Pollution C. Decreasing Potable water D. Civic health problems Q.4 ______________ is passed and effectively implemented” refers to the implementation of: A. Amendmet Laws B. Legislation C. Legal Punishments D. None of these Q.5 ‘Plaguing’ in the passage, means: A. Casuing trouble B. inviting C. avoiding D. encouraging Q.6 Which problem is highlighted in the given passage? A. Reduction of groundwater B. Droughts C. Water Pollution D. All of the above Q.7 According to the passage, women in remote areas A. try to obtain little water B. have to travel long distances to get water C. Cause water pollution D. die due to thirst Q.8 Choose the option that correctly states the meaning of ‘dumped’, as used in the passage A. Garbage B Threw C. Wasted D. Sold Q.9 Which of the following is a threat to the residents of Delhi 1. Zero groundwater 2. Lack of potable water 3. Lack of the treatment of sewage 4. Yamuna is over-polluted A. 1,3 and 5 B. 3 and 4 C. 1,2 and 5 D. None of these Q.10 The Delhi Administration is worried about…………………… A. threat to civic health posed by polluted waters of Yamuna B. the rivers are becoming a major source of diseases C. Lack of memory D. Both (A) and (B)

However, their absence can spell trouble for a lot of us. Beginning with a school project to electricity payment to work from home, computers have become part and parcel of our daily lives. Though many of us maybe averse to the idea of machines pervading into our daily lives, they have come to become the unavoidable necessity.
