The Elixir of Life Questions and Answers, Notes, Summary
I. Answer briefly the following questions.
What is the imaginary elixir of life?
The divine amrita which can make man immortal.
What according to the writer is the real elixir of life?
What is the ‘wonderful difference’ the writer talks about in paragraph 2?
The ‘wonderful difference’ the writer talks about is between the two areas: the Libyan desert and the Nile Valley – the sea of billowing sand without a speck of green on the side of the Libyan desert and the green, fertile, densely populated area on the valley of the Nile in Egypt.
What brought about this wonderful difference?
The wonderful difference was brought about by the water of the river Nile flowing down to the Mediterranean from its sources a couple of thousands of miles away.
What is the ‘cheering sight’, mentioned in paragraph 5?
The ‘cheering sight’ to the writer is the filled rain-fed tanks that are so common in South India.
- What does the writer compare water in a landscape too?
- Why does he make this comparison?
- The writer compares water in a landscape to the eyes in a human face.
- He makes this comparison because water reflects the mood of the hour, being bright and bay when the sun shines, turning to dark and gloomy when the sky is overcast.
How does the water in rainfed tanks get its color?
The color of the water in rain-fed tanks is from the silt or finely- divided soil in suspension. This color varies with the nature of the earth in the catchment area and is most vivid immediately after a fresh inflow following rain.
What is the main cause of soil erosion?
Sudden bursts of excessively heavy rain resulting in a large run off of surplus water are the principal factors causing soil erosion.
What other factors add to the erosion of precious soil?
Contributory causes to the erosion of previous soil are the slope of the land, removal of the natural protective coat of vegetation, the existence of ruts along which the.water can flow rapidly gathering momentum, and the absence of any checks to such flow.
How can soil erosion be prevented?
Soil erosion can be prevented by terracing of the land, construction of bunds to check the flow of water, the practice of contour cultivation and the planting of appropriate types of vegetation.
How does the prevention of soil erosion serve a double purpose?
Adoption of techniques preventing soil erosion would also help to conserve and keep the water where it is wanted, i.e., on and in the soil.
What are the two sources of water mentioned in paragraph 10?
Rain and snowfall.
The land formed of silt in alluvial areas is always fertile (Say whether the statement is True or False).
_________ Takes place when water carrying silt mixes with the salt water of the sea (Complete the sentence with the appropriate word).
Planting of the appropriate type of vegetation will result in _________
a. the continuance of successful agriculture.
b. the terracing of the land.
c. preventing environmental pollution.
d. reducing the momentum of the flow of water.
(d) reducing the momentum of the flow of water.
What does the writer mean by ‘civilized forests’?
Forests created by the deliberate planting of saplings by human beings, as contrasted with wild and untamed natural jungles.
Mention any two advantages of civilized forests.
Civilized forests would, directly and indirectly, prove a source of untold wealth to the country. They would check soil erosion and conserve the rainfall of the country from flowing away to waste.
How will the development of hydro-electric power help to overcome the inadequacy of water supply?
The development of hydro-electric power would enable underground water to be tapped to a greater extent than at present, and thus help to overcome the difficulties arising from irregularity or inadequacy of other sources of supply.
Complete the following sentences with appropriate details:
a. The Nile Valley is the creation of ________
the river itself. It was brought down as the finest silt in its flood waters, from the highlands of Abyssinia and from remote Central Africa, and laid down through the ages in the trough through which the Nile flows into the sea.
b. _____ are a ‘cheering sight’.
Rain-fed tanks in South India when they are full.
c. A remarkable feature of water is its power to carry ______
silt or finely-divided soil in suspension.
d. It is the silt which gives _____ to the water in rainfed tanks
the characteristic water.

b. What does “same” refer to?
“Same” refers to rainfall in India.
c. Why is Indian agriculture “very sensitive”?
Since Indian agriculture depends on seasonal rainfall and does not have many other sources of water, it is “very sensitive” – easily affected by inadequate or irregular rainfall.
They would check soil erosion and conserve the rainfall of the country from flowing away to waste and would provide the necessary supplies of cheap fuel, and thus render unnecessary the wasteful conversion of farmyard manure into a form of fuel.
a. What does “they” in the first line refer to?
Vegetation like shrubs and trees grown in order to check soil erosion.
b. What is the cheap fuel referred to in the passage?
Dried branches and leaves of trees grown to prevent soil erosion.
c. How would cheap fuel help the farmer?

He tells us that water is fundamental for human welfare.
What are the various causes of soil erosion? How can we prevent it?
- Heavy rain
- Slope of land, removal of vegetation, ruts which enable water to flow faster and absence of my barriers to check flow of water.
- preventive action would be terracing of land, consu action ui aunds to check flow, contour cultivation, planting of vegetation.
Paragraph : C.V. Raman tells that soil erosion is a major problem in India. Soil erosion happens due to several reasons: Firstly, a sudden downpour of heavy rain can result in excess water carxying top soil into the sea. Secondly, the slope of the land and the removal of the natural protective coat of vegetation, and the existence of ruts along which water can flow rapidly can giv. se to erosion. Thirdly, the lack of bunds to prevent water from flowing forcefully can lead to erosion of soil.

VI. Project : (Time limit: 10 days) (Your Teacher will help you)
Topic: Sharing Cauvery Water with Tamil Nadu.
Task: The class is divided into 4 groups. Each group focuses on one area of the problem-Collects information from different sources, organizes the material and makes an oral/power point presentation to the class. The tasks are given below.
- Group I: What are the demands of Tamil Nadu?
- Group II: What is Karnataka’s stand on this issue?
- Group III: What are the judgments were given by the Supreme Court and what are the orders issued by the Cauvery River Authority?
- Group IV: Interacts with all the three groups, notes down their findings and comes out with suggestions on how the problem can be resolved and makes a presentation to the class. (Important: ensure objectivity)
The sharing of water of the Cauvery has been a source of serious conflict between the states of Karnataka and Tamil Nadu. The genesis of this conflict rests in two controversial agreements signed in 1892 and another in 1924 between the erstwhile Madras Presidency and the Princely state of Mysore. The 802 km Cauvery river has 44,000 sq. km basin area in Tamil Nadu and 32,000 sq. km basin area in Karnataka.
- Group-I: The demands of Tamil Nadu:
Tamil Nadu pleads that it has already developed almost 3000,000 acres (12,000 sq.km) of land and, as a result, has come to depend very heavily on the existing pattern of usage. Any change in this pattern will adversely affect the livelihood of millions of farmers in the state.
- Group-II: Karnataka’s Stand :
The state of Karnataka contends that it does not receive its due share of water as Tamil Nadu does. Karnataka claims that the above agreements were very heavily in favor of Madras Presidency, and has demanded a negotiated settlement based on equitable sharing of the waters.
- Group-III: Judgements of Supreme Court:
A three-man tribunal was set up on 2nd June 1990. The Tribunal was headed by Justice Chittosh Mukherjee. The four states presented their demands to the tribunal.
Karnataka claimed 465 billion cubic feet; Kerala claimed 99.5 billion cubic feet; Tamil Nadu claimed the flow should be in accordance with agreements of 1890 and 1924, i.e. 566 billion for TN and Puducherry, 177 billion for Karnataka and 5 billion for Kerala.
Interim Order of the tribunal: ‘The tribunal considered TN’s demand and gave an interim order on June 25 1991, calculating the flow of water for 10 years from 1980-81 to 1989-90. Karnataka had to release 205 billion cu.ft. to TN monitored on weekly and monthly inflows. Karnataka expressed its inability to follow this order as a result of which there was violence, and schools and colleges were closed for a month.
In 1957, the government proposed Constitution of Cauvery River Authority. In 2002, things once again came to a head as a result of the failure of monsoon. A meeting of CRA was called on 27 August 2002, when the Chief Minister of Karnataka walked out.
The Supreme Court ordered the release of 1.25 billion cu.ft. every day, subsequently revised to 0.8 billion cu.ft./ day. Karnataka released for a few days and again stopped, pleading lack of stored water.
The Cauvery Water Dispute Tribunal announced its final verdict on 5 Feb. 2007. According to this, Tamil Nadu is to get 419 billion, Karnataka – 277 billion, Kerala – 30 billion and Puducherry – 7 billion. The actual quantity of water to be released by Karnataka amounted to 192 billion annually. The Government notified the tribunal’s order.
- Group-IV: The Governments of Karnataka and Tamil Nadu
In the interests of the farmers dependent on the Cauvery water in all the riparian starts should sit together and implement immediately a decision to desilt the KRS dam so that the rainwater going to sea is reduced and so is the water shortage. This would increase the quantity of water available for sharing. Similarly, an effort should be made to enhance the storage in Mettur dam, thereby, instead of fighting for water, the available storage water area is increased wherever possible, and judicious use of water is undertaken.
VII: Grammer Revisited:

The Elixir of Life Summary in English
1. Dr. C.V. Raman is a great scientist. His explorations are mainly in the field of optics. “Raman Spectra” is one of the greatest explorations in science field invented by him. Water has more importance for us. Unless the water, it is impossible to live in a proper way. Water is the elixir of life.
2. Dr. C. V. Raman gave an important task on the water that water gives beauty to nature such that when the sun shines or sets, that rays in the pond or river give beautiful, tremendous vision to us. Mainly, water adds beauty to the countryside. In South India, all tanks are filled with rain water with cheering sight.
3. Dr. C.V. Raman also suggested to humankind that the conservation and utilization of water is fundamental for human welfare. The precious fluid known to be water is lost if the water is not controlled.
4. Like this Dr. C.V. Raman gave an elaborate note of the unique power of the elixir of life, called water. When water carries silt or fine soil, water takes the color of the soil with which makes the land fertile. This flow of water makes a beneficial role in the formation of the earth’s surface. If we neglect this water, this water can, swept away the silt and finally destroy agriculture.
5. In the absence of plain water, it makes a land a dry and lifeless desert, but the presence of water then it turns the land most fertile.
