Read the following passage carefully and then answer of the questions given below:

The world is not only hungry but also thirsty for water. This may seem strange to you. Since nearly 75 percent of the earth's surface is covered with water. But about 97 percent of this huge amount is sea water or salt water. Man can only drink and use the other 3 percent, the fresh water that comes from rivers, lakes, under ground and other sources. And we cannot even use all of that because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, this small amount of fresh water which is constantly being replaced by rainfall is still enough for us. But our need for water is increasing rapidly almost day by day. Only if we take steps to deal with this problem now we can avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one example of how necessary water to industry. Do you know that to produce a single ton of steel, it takes about 91000 liters of water?

We all have to learn how to stop wastage of our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field but only on a small scale. The systems that have been worked out resemble those uses in spacecraft.

Question:

(i) Why cannot we use all of the earth's fresh water?

(ii) How is the amount of fresh water replaced?

(ii) Why is our need for water rapidly increasing?

(iv) Where does the fresh water come from?

(v) How can we stop wastage of fresh water?

Read the following passage and answer the question:

Some people love to watch telorision sitting alone in their living rooms in the orening. There are others who pass time, engaging in gossip. People who temporarily withdraw their attention from their immediate surroundings for the pleasure of building castles in the air are not at all hard to see. Oren the most fidgety children enjoy sitting quietly for an hour or two and playing computer game. All these are nothing but pleasurable diversions. Amusements can, therefore, be of wide variety. One cannot imagine living a life without some form of amusement now and then. An amusement, of whatorer type it is, makes time pass pleasantly.

Now, of all the amusements which can possibly be imagined for a hard working man, after his day's toil, there is nothing like reading an entertaining book. It calls for no bodily exertion, of which he has had enough. It reliores his home of its dullness. It transports him to a lovelier and more interesting world of scenes and beauties. And while he enjoys all these, he may forget the orils of the present moment. It accompanies him to his day's work. If the book he has been reading be anything, above the very idlest and lightest, it gives him something to think about during the drudgery of his oreryday occupation. If I were to pray for a taste which should stand me in good, stead under orery variety of circumstances and be a source of happiness and cheerfulness through life, it would be a taste for reading. Give a man this taste and the means of gratifying it, and you can hardly fail to make a happy man of him. You place him thus with the best society in orery period of history, with the wisest, the bravest and the purest characters which have advanced humanity. You make him a citizen of all nations, a contemporary of all ages.

(a) Reading an entertaining book requires somebody no amount of physical labour.

(b) A taste of reading is a sign of culture.

(c) Diversions are needed to break the monotony of life.
