NCERT Class 11 English Reading Discursive Passages

NCERT Solutions for Class 11 English Reading :: Discursive Passages

Unseen Passages for Class 11 CBSE With Answers PDF – Discursive Passages:

Read the following passages carefully:

Passage 1:  The art of reading right

Reading Comprehension (RC, as it is normally called) is the most peculiar section in almost all scholastic, entrance and employment tests. The skills in RC make a lot of difference to one’s chances of good grades/selection.

Most students find it difficult to tackle topics that are diverse from the field they are in or they are comfortable with. So one needs to develop a taste for even the most obscure and boring topic on this planet. For success in RC one should be able to understand. And even with an average speed one can succeed if one implements the strategies.

Broadly speaking, RC passages can be classified in a few categories. Fact based RC is the simplest form of RC. These types of passages have lot of information in the form of names, numbers etc. In this type of passages one should read very fast.

Don’t try to memorize any facts, numbers or names etc. In fact there is no need to even remember them. Just make yourself familiar with the structure of the passage. Just see in which paragraph author is talking about what. Mark it. Then when you go to the questions, identify in which paragraph information regarding that question is mentioned. Go to that paragraph, read the numbers, names etc. and mark the answer.

Inference based RC is the toughest form of RC. Here the passage is fairly tough to understand. This includes passages on topics like Religion, Spirituality, Philosophy, etc. Most of the students will be comfortable attempting these passages at least in RC. The reading speed is fairly slow in this type of passages. The way to master this type of passages is to read them again and again while practising.

Topic based RC includes passages on any particular topic like economics, astrology, medical science, etc. Generally what makes -these passages tough is usage of technical terms. If a topic is new to us then presence of technical term scares us even if they are defined in the passage. For success in this type of passages we need to have a fan-understanding of the definition of the term if it is defined in the passage. Read that definition twice if you need to. But don’t worry about technical terms if they are not defined in the passage. Assume them to be non-existent and proceed. Key principle in these passages is that don’t go to the next line unless the previous line is clear.

Reading passage first and then questions is the most popular strategy for RC. While answering the question you may come back to the passage to find answer as you have just read the passage initially and not crammed it. But you should not come back for each and every question. If you come back for majority of questions then you haven’t read the passage properly. The key to success for this strategy is that you should understand the passage very well. We will suggest students to follow this technique from the beginning and work upon this.

Reading questions first and then passage is the strategy followed by a few students. They just look at the questions and not options. The objective is that after seeing the questions when you read the passage then you read only that part carefully where the answer is given. The flaw with this is that you will not be able to remember all the questions. Besides this, this strategy fails when there are questions that require understanding of the passage.

A. Answer the following questions by choosing the most appropriate option:    6

Most students find Reading Comprehension difficult because……………………….(a) the language is tough(b) the vocabulary is difficult(c) the style is too involved(d) the topics are unrelated to their interest

The word ‘diverse’ in para 2 means……………………….(a) similar(b) same(c) variety(d) different

B. Answer the following questions in brief:    67. What should one do for finding the right answers?8. Why is topic based R C tough?9. Which step is considered more essential for finding right answers?

Passage 2:Playing the mind game

The Mastermind quiz is billed as a “battle of minds’. This battle is fought in two halves. In the first, each of four participants faces a barrage of questions, for two minutes, on any topic of his or her choice. In the second round, the questions are on general knowledge. There are two points for each correct answer and zero for wrong answers and passes. In the event of a tie, the person who has passed fewer questions wins.

Questions can be bizarre, but they are answered none the less. “It absolutely amazes you that these guys know so much. In KBC, it used to be, that this guy knows so little,” says Basu after the show. Siddhartha Basu was the director of Kaun Banega Crorepati (KBC).

This year’s Mastermind final was won by Ramanand Janardhana, a 22 year-old software engineer from Pune. Janardhana had Agatha Christie’s ‘Tommy and Tupence’ novels as his specialist topic. He even knew that Tommy used asofoetida to create a stink in his room.

There are, of course, all sorts of quizzers. The diary-toting, Manorama yearbook, wielding variety will typically prepare for a contest by ‘studying’. He knows that the best questions, the ones that get the ‘wah-wahs’, are always repeated. He is a solid quizzer, because he knows the obvious.

There is the other kind, like Janardhana, who claim they do nothing extra to prepare for quizzes. They read the papers and magazines, watch TV, and become quizzers because they enjoy the test of recall.

It was a test the nation took when KBC fever was at its height. But long before KBC, there were quiz societies across the country, in places from Guwahati to Gandhinagar. Kolkata was the hub of the game; quizzing in India began here in 1967. Even now, the majority of quizzers are from Kolkata. Of the four 2002 Mastermind finalists, two were from that city.

Quizzing is big in school and college festivals. It’s the ‘literary’ highlight of all fests. There are even professional quizzers, who, like mercenaries, play for money and the thrill of the game. They represent various organisations at different times.

Most quizzers grow out of active quizzing after college. Some, the really hardcore devotees of the game, keep at it. “I don’t get tired of quizzing,” says Pinaki Prasad Roy, a Mastermind finalist. “I get excited.” Roy is a 46-year old finance professional from Kolkata, and has been a quizzer for three decades.

Curiosity is the most essential quality for a quizzer. A fantastic memory and instant recall help. And for Mastermind at least, the choice of specialist subject is critical. In this year’s event, Janardhana took an unassailable lead in the specialist round itself.

A. Answer the following questions by choosing the most appropriate option:    6

The Mastermind quiz is called a ‘battle of minds’ because……………………….(a) it is a duel of wits(b) the participants are the most intelligent persons(c) the participants face a shower of questions(d) the mind is on the anvil

The participants in the quiz seem ‘masterminds’ because……………………….(a) they seem to know so little(b) they have very polished manner(c) they show lot of self confidence(d) they seem to know so much

Ramanand Janardhana won as……………………….(a) he had mastery over the specialist topic(b) he had gone through the quiz columns in magazines(c) he had chinks in his memory/recall(d) he knew all the often repeated questions asked by quizmasters

The studious quizzers are called ‘solid’ quizzers because……………………….(a) they prepare expected questions(b) they know the obvious(c) they bank on general awareness(d) they enjoy the test of recall

The quality most essential for a quizzer is……………………….(a) love of learning(b) mathematical accuracy(c) curiosity to know(d) comprehensive learning

The word ‘mercenaries’ in para 7 means.………………………(a) those who seek mercy(b) those who work on machines(c) those who are lively and quick(d) those who fight for money

B. Answer the following questions in brief:    67. Why did Ramanand Janardhana win mastermind final?8. Who are called solid quizzers? Why?9. Which is the most essential quality of a quizzer?10. How is Kolkata associated with quizzing game?11. Find the words from the passage which are similar in meaning to these words.(a) Those who fight for money (para 7)(b) Enthusiasts (para 8)

Answers

(c) the participants face a shower of questions

(d) they seem to know so much    .

(a) he had mastery over the specialist topic

(b) they know the obvious

(c) curiosity to know

(d) those who fight for money

He had mastery over the specialist topic which blessed him with victory.

The studious quizzers are called solid quizzers they know the obvious.

The quizzer should have curiosity to know.

Quizzing in India began in Kolkata in 1967. Even now the majority of the quizzers are from Kolkata.(a) Mercenaries(b) Devotees

Passage 3:Living with foods

Floods are not new to India and this sub-continent, but in recent years the problem has received much greater attention perhaps largely because it has led to much greater damage than in the past. Even though information on the impending occurrence of floods is now more accurate and certainly more timely, often there is very little time or support infrastructure in place by which damage can be minimized. This is particularly true in the case of flash floods resulting from sudden and excessively heavy rain.

In the case of India flooding is very much a function of the seasonal nature of our rainfall. The monsoons are spread over a short period during the year and often bring a concentrated volume of rain, which cannot be absorbed by the earth and finds outlet only in the form of streams that join up with our major river systems. But, flooding is not confined only to the main rivers of the country, often smaller tributaries and streams can cause heavy damage as well. Once these streams spill over their banks they could cause excessive harm, mainly because those living near the banks of these streams particularly in mountain areas do not have easy recourse to moving away quickly.

One major factor that could lead to a higher severity of flooding in the future is the danger of climate change. While the evidence of the nature of impacts resulting from climate change on precipitation and flooding at the regional level is not entirely clear, it could happen that the Indian subcontinent witnesses and suffers the effects of a significantly changed pattern of monsoons. One set of scientists has estimated that the monsoons could be shorter in duration, but far more intensive. In other words, much greater precipitation would take place in a much shorter period of time, thereby increasing the danger of floods. Climate change is the result of human actions through the increased concentration of greenhouse gases in the atmosphere, of which carbon dioxide is the most prominent.

At the local level also human actions have heightened the danger of flood through the cutting of trees in the mountains as well as in the plains. In the case of India, the ecological damage through deforestation of the Himalayas has led to large-scale erosion of the mountain slopes and high levels of siltation. This leads to deposition of silt on the riverbeds in the plains and hence spill over of water whenever the volume in the river reaches a certain level. With siltation on the river beds, flooding occurs even at very shallow water levels. The vulnerability of the population has increased substantially because of population pressures, symbolized, for instance, by the stubborn and perhaps helpless settling of slum dwellers on the banks of the river Yamuna in Delhi, which is merely a trickle most of the year, but bursting its banks during the monsoons as has been the case this year.

Flood forecasting is critical to minimizing the damage from floods. It is for this reason that the Central Water Commission has set up a network of forecasting stations, which cover the most important flood prone inter state rivers in the country. These stations produce forecasts that are used to alert the public and to mobilize various official agencies so that they take both preventive as well as relief measures whenever required. However, even in cases where forecasts have been timely and generally accurate, people have often been reluctant to move away, because in most cases they lack the means and physical options for moving away from a danger zone to one that is relatively safe. In the case of flash floods, forecasts are difficult to make, and often the time available for relief is very short.

A. Answer the following questions by choosing the most appropriate option:    6

The problem of floods has been considered important recently because…………………..(a) there are flash floods(b) floods are unpredictable(c) the rivers change their courses(d) these cause much greater damage

The danger of floods is not minimised as…………………..(a) flood forecasting is inaccurate(b) there is little time available for safety measures(c) people are scared and act in panic(d) support infrastructure is poor

India suffers from floods during monsoons because…………………..(a) it rains very heavily and continually(b) the embankments of the rivers are weak(c) the streams and rivers spill over(d) the streams are full of silt

Climate change is the direct result of…………………..(a) increased concentration of green house gases(b) explosion of nuclear devices(c) fire in oil wells in the gulf region(d) significantly changed pattern of monsoons

The worst hit people are slum dwellers because…………………..(a) they are stubborn and helpless(b) they do not have means to move away quickly(c) they have concentrated in large numbers(d) they have settled on the banks of the rivers

The word ‘precipitation’ in para 3 means…………………..(a) forming a precipitate(b) separation of solid material from liquid(c) falling of rain in an area(d) the quality of being exact or accurate

B.

Passage 4:Great Indian digital divide

The revolution in information technology (IT), far from helping India to leapfrog to a post-industrial society, threatens to rupture the social fabric by enriching a few at the cost of many.

In a very short time and quite unexpectedly, India has risen to considerable eminence in the world of information technology. This year, software products are expected to account for $ 5.7 billion in exports and will account for a quarter of the growth in the economy, which is expected to grow nearly seven per cent. Within eight years, predicts a recent study by McKinsey & Co. and the National Association of Software & Service Companies (Nasscom), India’s annual IT exports could hit $ 50 billion about 33 per cent of global software exports. Such a surge is expected to generate 2.2 million jobs—and push our growth rate near the double digits that many East Asian Tigers enjoyed before the 1997 crash.

For the rapidly growing middle class, which was desperate to make its presence felt but remained mired in the great Indian outback of the global economy and regretfully watched the industrial revolution pass it by, this is the moment they have been waiting for. When countries like Japan and Germany, the objects of Indian admiration, should come knocking on our doors to solicit our talent to invigorate their industry, it is indeed redemption of sorts. And IT is the cause of it all.

The big question is, will IT do an encore for India as a nation, and not just for a wafer thin percentage of IT-literate Indians, mostly the poster boys of the IITs?

IT has, as yet, failed to touch the lives of the average citizen and India is nowhere close to being a knowledge economy or society. As per the International Data Corporation (IDC), in a survey of 55 countries, India ranks 54th on its Information Society Index.

The fact is, it is a straightforward reflection of the deep inequality of our education system which breeds a few ‘geniuses’ at the cost of the entire nation. A study by former director of the National Centre for Software Technology, R. Narasimhan, points out that nowhere is the digital divide more glaring than in IT education. The report warns that India’s ‘obsession’ with the software industry and its exports orientation is leading to the churning out of unemployable students on one hand and bright whiz-kids on the other. While the latter are lured away by overseas employers, the former remain unemployable.Narasimhan cautions against the ‘hype’ associated with the phenomenal growth of India’s software industry defying rational explanations and built up into a ‘mystique of sort’ which breeds false hopes. .

India’s software industry is a poor employment generator. In the mid-Nineties, some 20,000 people were actively employed in software export services. In contrast, there were three million registered unemployed graduates in the Nineties. While the ‘Narasimhan study doesn’t mention number of hobs lost due to computerisation, one could comfortably add a million to the number.

Passage 5 :Deleterious effects of drugs

“Cured yesterday of my disease, I died last night of my physician,” says Matthew Prior, a celebrated pharmacologist, while talking about the deleterious effects of drugs in his book, “The Remedy Worse Than the Disease”. There is no dearth of patients dying of misguided treatment.

disorder bound to disappear in a short duration.

In this era of drugs we must familiarise ourselves with the term “Iatrogenic disease (physician caused ailment)”. When a physician administers medicines without a complete understanding of the patient’s condition, drugs play havoc. A person may become the victim of a worse disease or even lose his life.

With Analgin, for instance, special precautions should be taken in case of pregnancy, bronchial asthma, renal and hepatitic dysfunctions and blood-related disorders. It has been banned in several countries, including the USA and Sweden, because of its unexpected and negative effects that lead one even to death through an anaphylactic shock. An anaphylactic shock is a process that leads to a severe fall in the blood pressure, bronchoconstriction, the swelling of blood and lymph vessels and sometimes death because of the loss of fluid in these vessels. Anaphylaxis usually occurs suddenly, in minutes after the administration of a drug. The well-known drug, penicillin, and many other drugs, may cause anaphylaxis.

The term “side-effects” is a part of an ailing layman’s vocabulary but adverse drug reactions are known only to a more aware and literate patient.

Ciprofloxacin, when given for an ear-infection, may cause vertigo and amoxycillin, while fighting a throat infection, may hurt the stomach. Similarly, while chemotherapy given for cancer may lead to indigestion and hair fall, steroids administered continuously may lead to obesity and diabetes.

Drugs are meant to eliminate disease. In the quest for avoiding the misery of sickness, man has invented medicines that may themselves cause diseases. The illness caused by a drug may be short-term or long-term. Side effects are short-term and predictable. The unpredictable and bizarre reactions are termed as adverse reactions. A variety of drugs cure many ills but are also known to cause irregular heart beat and even sudden death.

A strong sense of responsibility on the physician’s part and an attitude of extreme caution on the patient’s part can substantially help in covering at least some of the risks of medicines, if not all. There are many factors that help a doctor in his choice and use of the drug. The medical history of a patient, age, sex, personality, environment and education contribute in deciding the course of treatment. The very old and the very young are likely to suffer as their bodies are less tolerant. Older children may sometimes be more tolerant than the adults. The elderly tend to respond better to standard drug dosage. But the lower body size, slow blood flow to vital organs, decreasing metabolic capacity and tendency to multiple physical problems contribute to adverse reactions.

A. Answer the following questions by choosing the most appropriate option: 6

An “Iatrogenic disease” is an ailment caused by……………………………(a) infection in the hospital ward(b) overdose of anaesthetic(c) the wrong administration of drugs by a physician(d) self-medication and buying drugs over the counter

B. Answer the following questions in brief: 67. What is an adverse drug reaction?8. Why are elderly people prone to adverse drug reaction?9. What are the factors that help a doctor in his choice and use of drugs?10. Why has man invented medicines?11. Find words from the passage which are similar in meaning.(a) Not working properly (para 4)(b) Considerably (para 8)

Answers

(c) the wrong administration of drugs by a physician

(d) these may cause anaphylaxis

(b) a drug having unpredictable and strange effects on a patient

(a) diseases

(c) slow blood flow to vital organs

(d) not working properly

An unpredictable and strange effect on a patient is called an adverse drug reaction.

Elderly people’s blood flow to vital organs is slow so they are prone to adverse drug reaction.

The factors like medical history of the patient, age, sex, personality, environment and education help a doctor in his choice and use of drugs.

Man has invented medicine to eliminate the misery of sickness.

(a) Dysfunction(b) Substantially

Passage 6:Saving for a rainy day

The Food Bill is still in the works but has provoked a furious debate on the lack of grain storage facilities, rotting of grains and whether they should be distributed free to the hungry masses. Waking up to the fact that no food security programme can be effective without proper storage, the government is now planning to upgrade existing warehousing facilities and also adding new ones. However, between food security and large-scale storage, there’s a missing link that needs to be taken note of: storage at the farm level. No one can deny the importance of decentralised storage; at least 25-30 per cent grains in the country are stored at the farm level.

However, it’s not as if there hasn’t been enough thrust on this issue: there are State institutes to look into the storage problems.

Yet, policy-wise we did have a sound start: the Save Grain Campaign, which was initiated 43 years ago, was supposed to do what we are floundering on now. Through this campaign, the Centre was to initiate and train states in warehousing and storage of grains. The Centre wanted the states to take it up on a large scale but the latter did not want any “added responsibility”. Finding no takers, the campaign was withdrawn in 2008.

“Around 15-20 per cent foodgrain losses occur in large storage godowns. Along with investment in large storage capacities, we must encourage farm-level storage. This can be in the form of refining and improving the local/indigenous storage technologies and providing technical and financial support at that level,” says M.B. Chetti, Dean, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka.

He and many experts like him suggest that if we want to leapfrog in storage capacity at the farm-level (since setting up large storages is time-consuming and expensive), new technologiese vacuum packaging could be the answer. They assure quality as well as a chance to store grains almost anywhere and that it can be done in villages by trained persons.

“Alternatively, we have to go for cold storage facilities for food grains, which is very costly since it involves electricity supply,” says Chetti. Instead, vacuum packing, say experts, helps preserve grains and seeds for long periods without any deterioration in quality. In fact, an experiment was carried out in the university on the usefulness of the packaging system (using chilli) and the results were satisfactory. The available technology offers a seven- layer packing to preserve quality for long periods of time and once sealed, climatic changes have no effect on it. Elimination of oxygen from the pack helps in extending shelf life.

“At present only three-layer plastic films are manufactured in India. The seven-layered film needs to be imported. But the import duty is high,” says Mohan Bajikar, of course, such technologies are expensive, but then delivering to the hungry isn’t enough—quality must be ensured.

Fool policy analyst Devinder Sharma, however, says expensive solutions like silos and warehousing are not the answer to procurement and storage problems. Instead, he says, “local production, local procurement and local distribution” is the answer, something like what Chhattisgarh has been doing. It procures paddy directly from farmers, buying it through cooperative societies and procurement centres at the village level. To store, he adds, the government can add a small godown next to each panchayat ghar.

Whichever way we look at it, decentralised storage cannot be left out of the loop if we want to ensure food security and reduce stock losses.

A. Answer the following questions by choosing the most appropriate option: 6

The necessity of proper storage has been realised because……………………(a) there is lack of grain storage facilities(b) grain is lying in the open and rotting(c) no food security is possible without it(d) masses are hungry and without grain

Decentralised storage stress upon……………………(a) storage at farm level(b) storage at block level(c) storage at district level(d) storage at state level

The ‘Save Grain Campaign’ was withdrawn after 43 years because……………………(a) the centre did not spare funds(b) proper training in warehousing was lacking(c) the states did not show any interest(d) the states did not want any added responsibility

The most cost-effective solution for storage of grain is……………………(a) cold storage facilities(b) decentralised storage(c) setting up large warehouses(d) vacuum packaging

Experts reject silos and warehousing because……………………(a) these are very costly solutions(b) local storage and distribution is more effective(c) these are inadequate for storage(d) these fail to reduce stock losses

The word ‘facilities’ in para 6 means……………………(a) aptitude(b) dexterity(c) conveniences(d) buildings for a particular purpose

B. Answer the following questions in brief: 67. Why was save green campaign withdrawn after 43 years?8. Which is the most cost effective solution for storage of grain?9. How are new technologies like vacuum packaging more successful in storing?10. Why do experts reject soil and warehousing?11. Find the words from the passage which are similar in meaning?(a) Improve (para 1)(b) Native (para 4)

Passage 7:The relevance of repetition

The painstaking memorisation of mathematical tables, historical dates, capitals of countries and even poems leaves an indelible mark on every adult who has attented school. However, all educators deprecate this rote system learning by orally reciting and consigning lessons to memory as mindless and mechanical, which goes against critical thinking and creativity. But is this dichotomy between creativity and rote learning part of a lazy binary thinking?

We often hear about people who can repeat the entire telephone directory or memorise the entire dictionary. Indians have a history of highly developed systems of memorisation, perfected through centuries of Vedic learning. From a typically Western perspective, the permanency of the written word has been pitted against the ‘unconscious operation of memory’ of oral cultures, and held to be more reliable in cultural transmission. However, refuting this thesis, Fritz Stall, an Indie scholar observes that the oral tradition in India is remarkable, “because it has led to scientific discoveries that are of enduring interest”. Of course, this mugging up can be aural (i.e. chanting aloud) or visual—mentally storing images in a visual map.

The advantages of rote memorisation—like it expands areas of the mind to great possibilities—are now becoming evident to the world. Various accounts from ancient India, including those from travellers like I-tsing, point to the fool-proof system of oral memorisation and the capacity to absorb volumes of data.

A parallel dimension of transmission of knowledge also existed in India, with a flexible mode of oral communication through which knowledge was disseminated. One instance is the narrative-performative tradition of recitation, which extended basic story through interpolations, conscious extensions and embedding of sub-narratives. Many Indian myths, legends, epics, and fables such as Kathasaritsagara and Jataka stories were spread though this process. While the story remains the same, the interpretation changes according to who says it, where it is said and how it is said. While communicating mathematics, philosophy and other scientific disciplines, cryptic text forms were created, that facilitated memorisation.

A related question pertains to cognition—how can we transmit principles using memorisation as a creative tool rather than as a mechanical process of repetition? Bhaskara’s Lilavati, the seminal 12th century illustrates how memorisation and creativity go together.

The fact that Bhaskara’s methods still figure in Indian pedagogic consciousness was recently brought home in a news report on the Ramanujan School of Mathematics in Patna, which trains youngsters from poor families to clear the Indian Institute of Technology (IIT) entrance test. This year, all the 30 students of the school got through IITs. Anand Kumar, the school’s founder, called it the “sheer power of practice to break the so-called IIT code” and a student attributed the success to his teacher’s ability to teach differential calculus through a “thrilling story of a daring robber”.

A. Answer the following questions by choosing the most appropriate option: 6

All educators condemn rote learning as…………………..(a) it is a feat of memory(b) it is a parrot like learning(c) it is mindless and mechanical(d) it is against critical thinking and creativity

The dichotomy between creativity and rote learning is…………………..(a) increased by computer literates(b) initiated by western thinkers(c) the clash of the cultures of west and east(d) opposed by Indian scholars
