Question
Read the following passage and do the activities.
In the early days of farming, people did not understand how plants obtained essential nutrients. It so happened that wood ash, fish remains and slaughterhouse waste were thrown on vacant land just to get rid of them. Then, people started to notice that the grass, bushes and shrubs on this vacant land began to grow very well. They reasoned that if their farmland were similarly treated, the growth of their crops would also improve. People gradually began to realize that the nutrients required by plants came from the soil and that the amount of nutrients could be increased by the application of such organic remains to the soil. Thus started the manuring process in farming.
The practice of manuring has been practised as early since the seventeenth century. However, the importance of manuring was not properly understood until scientists began to study the nutritional needs of plants and gave birth to fertilizers. Thus, gradually, the use of fertilizers became accepted by farmers.
There are many types of manure and fertilizer currently being used. Manure is a substance derived from animals and plants. The most important advantage of using manure is the fact that they not only supply a wide range of plant
nutrients, but also improve the structure of the soil. It cements together the soil particles to form soil crumbs. The crumb structure is a desirable condition of cultivated soil. The addition of manure to soil will increase the inorganic and humus content which helps to prevent soil erosion and loss of plant nutrients when it rains. The common manure used in farming consists of farmyard manure, compost, blood meal, bone meal and fish meal.
Unlike manure, fertilizers are inorganic substances which do not improve the structure of the soil. They only supply extra amounts of nutrients to the growing plants when applied to the soil. The commercial fertilizers commonly used today
can be classified into three major categories; namely, nitrogen (N), phosphate and potash fertilizers.
Besides knowing the type of fertilizer to use, a farmer also needs to know when to apply the fertilizer and how to apply it. The fertilizer should be applied at the time when the plants need a particular nutrient most. The time and method
of application will determine how profitably the fertilizers have been used in farming. Fertilizers which have not been properly applied cannot be absorbed in large quantities by plant roots. These fertilizers may be washed away by rain
or they may kill the plants. This would mean a definite financial loss for the farmer.

(c) Festival (d) Enclosure
Olympia, the original site of Olympic Games in ancient Greece is situated in a quiet, beautiful valley. The old ruins are shaded by evergreen oaks, pines and poplars, as well as olive trees. Olympia was never a city but a sacred ground occupied by temples and dwellings for the priests. At the centre was the enclosure known as Altis, dedicated to Zeus, the god of gods. It was in honour of Zeus that the quadrennial festival and the games were held.
The fame of Olympia rests largely upon Olympic Games. They were a great national festival of the entire Greek race. During the week of the festival the Athenians, the Spartans, the Syracusans and other groups, all forgot their narrow identities. They regarded an Olympic victory as the highest honour. The simple reward of a twig of wild olive immortalized the victor and his family.
The Olympic Games were held regularly in peace and in war at an interval of four years for over a thousand years from 776 B.C. till 393 A.D. Originally, men who spoke Greek as their mother tongue were allowed to compete in the Olympic Games. No married women were allowed to be present. The athletic programme was varied by the presence of historians, orators and writers. After each event a herald announced the victor's name and handed him a palm. On the last day the successful competitors were each given a garland of wild olive.

It was late evening of July 20. 1969, when we turned up the hostel radio. I was an engineering student at BITS, Pilani. I still remember the feverish excitement that gripped us from July 16 when Apollo 11. the US space rocket, took off from Cape Kennedy, Florida. Neil Armstrong and his team of astronauts, Edwin "Buzz" Aldrin and Michael Collins, were to land on moon, for the first time in human history. We listened 'with rapt attention when Armstrong declared: "That's one small step for a man, one giant leap for mankind."
His death on Saturday, August 25, is a moment to salute the romance of space science that Apollo 11 unleashed. It has changed forever the way we look at our planet Earth and its satellite, the moon.
Standing on powdery moondust, Armstrong put up his thumb, shut one eye and found his thumb blotting out the Earth. "It suddenly struck me that that tiny pea, pretty and blue, was the Earth” he said later. "I felt very, very small." But behind that humbling realisation stood a giant truth:
The effort to explore the universe united mankind in technology and knowledge. Each moon mission, about 110 till date, provided more confidence to take on bolder projects.

‘I am proud to be Sir Rowland's son,’ answered Orlando angrily,’ and I would not change my place to be the heir of this dukedom.’
The Duke and his lords went away, leaving Orlando alone with Rosalind and Celia. Celia was angry with her father for speaking so unkindly to Orlando. ‘Would I have done this in my father’s place?’ she said to Rosalind.
‘My father loved Sir Rowland as much as his own soul,’ Rosalind said to Celia, ‘and all the world agreed with him. If I had known that his young man was Sir Rowland’s son I should have begged him with tears not to take so great a risk.’
‘Let us go and speak to Orlando,’ said gentle Celia. ‘I am ashamed of my father’s rude and angry words.’
The two girls went up to Orilando and praised him for his bravery. Rosalind took a gold chain from her neck and gave it to him. ‘I would like to give you more’, she said, ‘but I am not rich.’ Then she and Celia went away.
Orlando, however, could not forget them. He had already fallen in love with the fair Rosalind, but he could not stay at the Duke’s palace. His friends warned him that Frederick was angry and jealous of him. They told Orlando to leave the dukedom, because the Duke meant to do him harm.

My mother was still managing Green's, even though its days were numbered. The day after my return I joined her in the small office, where she sat behind her over-large desk, telephone on her right and the latest paperback western before her, ready to be taken up when noting much was happening – which was fairly often. My mother enjoyed reading westerns-particularly Luke Short, Max Brand, and Clarence E Mulfordmuch in the same way that I enjoyed detective fiction. Both genres were freely available in cheap collins ‘White Circle’, edition published during and just after the War.
We discussed the affair of the skeleton in the cupboard, but as there was no longer any mystery about it, there was nothing for me to investigate. However, armed with the key to the store room, I went down to the basement on my own and made a thorough search of all the old furniture, on the offchance that another skeleton moght tumble out of a cupboard or be found jammed into a drawer or trunk. I did find some old tennis rackets, back numbers of Punch, a cracked china chamber-pot, some old postcards of Darjeeling and Simla, and a framed photograph of King Edward the Seventh. I took the copies of ‘Punch’ to my room and read the reviews of all the plays that had been running in London between 1926 and 1930, thus becoming an authority on the theatre in England of that period.

To read a lot is essential. It is stupid not to venture outside the examination 'set books' or the textbooks you have chosen for intensive study. Read as many books in English as you can., not as a duty but for pleasure. Do not close the most difficult books you find, with the idea of listing and learning as many new words as possible. choose what is likely to interest you and be sure in advance, that it is not too hard. You should not have to be constantly looking up new words in the dictionary, for that deadens interest and checks real learning. Lookup a word here and there, but as a general policy try to push ahead. guessing what words mean from the context. It is extensive and not intensive reading that normally helps you to get interested in extra reading and thereby improve your English. You should enjoy the feeling which extensive reading gives. As you read, you will become more and more familiar with words and sentence patterns you already know, understanding them better and better as you meet them in more and more contexts, some of which may differ only slightly from others.

Read the passage given below :
Success
Everybody wants to succeed in life. For some, success means achieving whatever they desire or dream. For many, it is the name, fame, and social position. Whatever be the meaning of success, it is a success that makes a man popular.
All great men have been successful. They are remembered for their great achievements. But it is certain that success comes to those who are sincere, hardworking, loyal, and committed to their goals.
Success has been man's greatest motivation. It is very important for all. Success has a great effect on life. It brings pleasure and pride. It gives a sense of fulfillment. It means all-around development. Everybody hopes to be successful in life. But success smiles on those who have a proper approach, planning, vision, and stamina. A proper and timely application of all these things is bound to bear fruit. One cannot be successful without cultivating these certain basic things in life. It is very difficult to set out on a journey without knowing one's goals and purposes. The clarity of the objective is a must to succeed in life. A focused approach with proper planning is certain to bring success. Indecision and insincerity are big obstacles on the path to success.
One should have the capability, capacity, and resources to turn one's dreams into reality. Mere desire cannot bring you success. The desire should be weighed against factors like capability and resources. This is the basic requirement of success. The next important thing is the eagerness, seriousness, and the urge to be successful. It is the driving force that decides success. It is the first step on the ladder of success.
One needs to pursue one's goals with all one's sincerity and passion. One should always be in high spirits. Lack of such spirit leads to an inferiority complex which is a big obstruction on the path to success. Time is also a deciding factor. Only the punctual and committed have succeeded in life. The lives of great men are examples of this. They had all these qualities in plenty which helped them rise to the peak of success.
Hard labor is one of the basic requirements of success. There is no substitute for hard labor. It alone can take one to the peak of success. Every success has a ratio of five percent inspiration and ninety-five percent perspiration. It is patience, persistence, and perseverance which play a decisive role in achieving success. Failures are the pillars of success as they are our stepping-stones and we must get up and start again and be motivated.
2.1 On the basis of your reading of the passage, answer any four of the following questions in 30-40 words each:
(a) To whom does success come certainly?
(b) What are the basic things in life we need to achieve success?
(c) What did great men have in plenty to rise to the peak of success? Give any two examples
(d) What is the one basic requirement of success?
(e) Explain: "Failures are pillars of success."
2.2 On the basis of your reading of the passage, fill in any two of the following blanks with appropriate words/phrase :
(a) ________________ plays a decisive role in achieving success.
(b) Goals have to be pursued with ________________ and ________________
(c) Ratio of success is ________________ inspiration.

(1) Plastic pollution has become one of the most pressing environmental issues, as rapidly increasing production of disposable plastic products overwhelms the world’s ability to deal with them. Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or nonexistent. But the developed world, especially in countries with low recycling rates, also has trouble properly collecting discarded plastics. Plastic trash has become so ubiquitous that it has prompted efforts to write a global treaty negotiated by the United Nations. (2) Plastics made from fossil fuels are just over a century old. Production and development of thousands of new plastic products accelerated after World War II. It transformed the modern age so much that life without plastics is unrecognizable today. Plastics revolutionized medicine with life-saving devices, made space travel possible, lightened cars and jets-saving fuel and pollution- and saved lives with helmets, incubators, and equipment for clean drinking water. (3) The conveniences plastics offer, however, led to a throw-away culture that reveals the material’s dark side: today, single-use plastics account for 40 percent of the plastic produced every year. Many of these products, such as plastic bags and food wrappers, have a lifespan of mere minutes to hours, yet they may persist in the environment for hundreds of years. (4) Most of the plastic trash in the oceans, Earth’s last sink, flows from land. Trash is also carried to sea by major rivers, which act as conveyor belts, picking up more and more trash as they move downstream. Once at sea, much of the plastic trash remains in coastal waters. But once caught up in ocean currents, it can be transported around the world. (5) Millions of animals are killed by plastics every year, from birds to fish to other marine organisms. Nearly 700 species, including endangered ones, are known to have been affected by plastics. Nearly every species of seabirds eats plastics. Most of the deaths of animals are caused by entanglement or starvation. Seals, whales, turtles, and other animals are strangled by abandoned fishing gear or discarded six-pack rings. (6) The solution is to prevent plastic waste from entering rivers and seas in the first place, many scientists and conservationists – including the National Geographic Society – say. This could be accomplished with improved waste management systems and recycling, better product design that takes into account the short life of disposable packaging, and reduction in manufacturing of unnecessary single-use plastics. |
Answer the following questions, based on the above passage:
- Which of the following statements best describes the reason why plastic pollution has become one of the most pressing environmental issues?
- Plastic trash collection systems have become inefficient or nonexistent.
- Rapidly increasing production of disposable plastic products overwhelms the world’s ability to deal with them.
- Some plastics have a lifespan of mere minutes to hours, yet they may persist in the environment for hundreds of years.
- The developed world, especially in countries with low recycling rates, has trouble properly collecting plastics.
- What is the tone of the writer in the given lines from paragraph 2? Rationalise your response in about 40 words.
‘It transformed the modern age so much that life without plastics is unrecognizable today.' - The passage includes some words that are opposites of each other. From the sets (A) – (E) below, identify two sets of synonyms.
- garbage and trash
- starvation and strangled
- disposable and reductio
- persist and downstream
- transformed and revolutionized
- Complete the sentence appropriately:
The writer says that most of the plastic trash is found in the Earth’s last sink and the reason it is transported around the world is _______. - Based on the reading of the passage, examine, in about 40 words, the downside of the convenience that plastic offers.
- Complete the sentence appropriately:
According to conservationists, the two ways in which most of the deaths of animals are caused are _______. - Based on the passage, how can we contribute to the reduction of plastic waste?
- by internationalising the waste management system
- by minimizing the use of single-use plastics
- by not abandoning fishing gear
- by not using helmets made of plastic
- State one reason why plastic pollution is most visible in developing Asian and African nations.

(1) Rotation of crops is a universal phenomenon which is practised by most of the farmers of the tropical and temperate countries. The main objective of rotation of crops is to obtain higher agricultural returns on the one hand, and to maintain the soil fertility on the other. (2) In other words, the rotation of crops helps in making agriculture more sustainable. The importance of crop rotation is more in the areas where farmers grow two, or more than two crops in the same field in a year. Irrigation facilities have also been appreciably developed in the country during the last three decades. The availability of water to the arable land has helped in the intensification of agriculture. (3) In the areas such as Punjab and Haryana, where the Green Revolution is a big success, one soil exhaustive crop (rice) is followed by another soil exhaustive crop (wheat). Subsequently, the field vacated by wheat is devoted to either rice or maize or cotton. Thus, in one year, the farmers are harvesting three soil exhaustive crops from the same field. Such a rotation of crops may fetch more income to the farmers, but depletes the soil fertility at a faster pace. (4) A number of field studies were conducted to assess the traditional crop rotation pattern. One such field study about the changes in the rotation of crops was conducted in the village Banhera (Tanda), Haridwar district. The main rotation of crops of the village is shown in the table below. |
| Traditional Rotation of Crops (1960-65) in Banhera (Tanda) | ||||
| Year | Kharif (mid-June to mid-October) | Rabi (mid-October mid-April) | Zaid (April to June) | No. of days land left fallow |
| 1960 | Millet/fodder/rice | Gram | Fallow | 90 |
| 1961 | Fallow | Wheat | Fallow | 210 |
| 1962 | Millet/fodder/rice | Gram | Fallow | 90 |
| 1963 | Fallow | Wheat | Fallow | 210 |
| 1964 | Millet mixed with urad/fodder/rice | Gram | Fallow | 90 |
| 1965 | Fallow | Wheat | Fallow | 210 |
Answer the following questions, based on the above passage:
- Fill in the blanks with the appropriate option from those given in brackets, based on your understanding of para 2.
One of the reasons that there has been an intensification of agriculture in the country is the development of irrigation facilities is a/an ______ (fact/opinion) because it is a/an ______ (subjective judgement/objective detail). - Based on your understanding of paras 1 and 2, state whether the following statement is true or false.
If proper irrigation facility is provided, higher agricultural returns can be obtained by making crop rotation more sustainable. - Justify the following in about 40 words.
Crop rotation may fetch more income to the farmers, but depletes the soil fertility at a faster pace. - Based on the table, mention the years when the land was left fallow for maximum number of days.
- The study conducted in village Banhera (Tanda) reflects that during the years 1960 to 1965, from April to June, the land was left fallow or uncultivated throughout. State any one inference that can be drawn from this.
- Select the option that correctly states the significance of crop rotation as given below:
- Crop rotation is done to obtain higher agricultural returns.
- Higher agricultural returns can be obtained by harvesting soil-exhaustive crops.
- Crop rotation demands that land should be left fallow for a few months to increase the fertility of soil.
- Better irrigation facility to the arable land has helped in the intensification of agriculture.
- If crops to be harvested are chosen wisely, crop rotation can help in maintaining fertility of soil.
