Read the passage given below carefully and answer the questions that follow.
1. Overpowering prey is a challenge for creatures that do not have limbs. Some species like Russell's viper inject poison. Some others opt for an alternative non-chemical method – rat snakes, for instance, catch and push their prey against the ground, while pythons use their muscle power to crush their prey to death. But snakes can't be neatly divided into poisonous and non-poisonous categories.
2. Even species listed as non-poisonous aren't completely free of poison. The common Sand Boa, for instance, produces secretions particularly poisonous to birds. So the species doesn't take any chance – it crushes its prey) and injects poison as an extra step.
3. Do vipers need poison powerful enough to kill hundreds of rats with just one drop? After all, they eat only one or two at a time.
4. While hunting animals try their worst to kill most efficiently, their prey uses any trick to avoid becoming a meal, such as developing immunity to poison.) For instance, Californian ground squirrels are resistant to Northern Pacific rattlesnake poison.
5. Competition with prey is not the only thing driving snakes to evolve more and more deadly poison. Snakes also struggle to avoid becoming prey themselves.
6. Some snake killers have partial immunity to poison. Famously, mongooses are highly resistant to cobra poison, and with their speed and agility, kill snakes fearlessly. It would be the death of cobras as a species if they didn't evolve a more deadly poison to stop mongooses.
7. Poison has another important role. It's an extreme meat softener, specific enzymes break up the insides of the prey. Normally, a reptile depends on the sun's warm rays to aid digestion.
8. But I wonder if we cannot use venom in our favour. In remote parts of India, local hospitality often involves leather tough meat. I chew and chew until my jaws ache. If I spit it out or refuse, our hosts would be offended, I swallow like a python stuffing a deer down its throat and hope I don't choke. If only I had poison.
(b) How does Sand Boa kill its prey?
(c) There is a constant tussle between the hunting animal and its prey? Why?
(e) What difficulty does the writer face when he is entertained in the remote parts of India?

उत्तर
2.1
(a) While Russell’s viper injects poison, the rat snakes catch and push their prey against the ground.
(b) The Sand Boa produces secretions particularly poisonous to birds. It does not take any chances and first crushes its prey and then injects poison as an extra step.
(c) While hunting animals try their worst to kill most efficiently, their prey uses any trick to avoid becoming a meal, such as developing immunity to poison. Competition with prey is not the only thing driving snakes to evolve more and more deadly poison. Snakes also struggle to avoid becoming prey themselves.
(d) Mongooses are highly resistant to cobra poison, and with their speed and agility, kill snakes fearlessly.
(e) When the writer is entertained in the remote parts of India, local hospitality often involves leather-tough meat. The writer chews it until his jaw aches. If he spits it out or refuses, their hosts would be offended and if he swallows, it would be like python stuffing a deer down its throat and hope that it doesn’t choke. Thus, he regrets not having a venom which he could use to soften the meat.

Read the following extract and answer the questions given below:
One day, King Amrit and Chandan were taking a walk on the terrace of the palace. The terrace offered a beautiful view of the surroundings, and they could see far into the distance. They spotted the weekly market from up there, with people in colourful clothes buying and selling all kinds of things. There was plenty to buy and people had money to buy too. There were no poor people to be seen anywhere. The King watched with a smile on his face. He was delighted to see the prosperity of his kingdom. Like any good ruler, he was happy ·when his people were happy.
He turned to Chandan and said, ''See how contented my people are. But I want to check this first-hand by talking to them. Tomorrow, summon people from all walks of life to the court, and I will ask them myself how they are doing.'' Chandan was used to the king's strange requests and went off to carry out this order.
The next day, the King arrived in the court humming a happy tune to himself. Seeing all the people gathered there waiting for him, he was even more pleased. He cleared his throat and said in a loud voice, ''I have called you here to ask you a very important question. As your king, I need to know if all of you are contented. Do you have enough for your needs? Do you know anyone who is not happy about anything?''.

Read the following extract and answer the questions given below:
There are some glimmers of hope. I met up young Navdeep. Ahuja who along with another colleague began the innocuously named Graduates Welfare Association, Fazilka. They are bringing about change with the mandate of citizens' participation in governance and are facilitating the creation of physical and social infrastructure across 22 cities in Punjab. They have put in place a network of cycle rickshaws called Eco-cabs which can be booked through a mobile phone. They are also developing car tree zones, food and culture streets in these cities. All this is being done very efficiently and at a low cost. We need many such organizations. However, my idea of a city in 2020 is not a utopian dream. It is achievable. It has streets where people walk on wide footpaths shaded by leafy trees. Streets are usually one-third of a city's area and its most democratic segment. Public space dedicated to pedestrians reduces inequality and should be accorded priority when developing cities. Adjoining the streets should be cycle lanes where bicycles and, rickshaws can sail past smoothly. It'll have a great public transport system with buses, metro and taxis. Parking will be difficult and expensive so people will use public transport rather than cars. There will be parks and gardens and the air will be clean, as pollution levels will have dropped dramatically. And then cities will become areas of graceful living and a charmed way of life.

Read the following extract and answer the questions given below:
So what is a city? It's a dense amalgamation of buildings and people. A city must provide equity and also be sustainable. As an architect who has been closely connected with Delhi and its planning, my wish list is more about the direction we need to take so that future generations don 't end up living in chaotic dysfunctional cities.
The first requirement for a city is a pragmatic plan. Many of our cities such.as Delhi and Bhubaneswar and even Port Blair in the Andamans have reasonably good master plans. Many also have City Development Plans which have been made an essential requirement to draw funds. from the government's Urban Renewal Programme (JNNURM). But they should be updated frequently based on the changing needs of its people.
And let's not forget its citizens - they need to be more pro-actively involved when evolving master plans. But often, there's lack of planning and inadequate implementation systems. This applies to all essential components of a city-streets, public transport system, traffic management, affordable housing, cars and parking, drainage. water supply, sewerage, and garbage. Any deficiency in these will lead to poor quality cities that won't be able to handle the pressure of increased population and changing needs.
The second require1nent of a good city is good social infrastructure such as parks and places for leisure such as rivers and seafronts. It needs to preserve and protect its heritage. We are a nation with a rich diversity in culture, arts, and crafts.
Questions:
(1) What issue is raised in the above extract?
(2) What are the requirements for a good city?

(1) The two organizations that conducted the research to develop a smartphone-based optical bio-sensor are _______ and __________ .
(2) The _________ and _________ methods were used in the research instead of the differential method.

Urea is a major product of nitrogen metabolism in humans. It is eliminated from the body mainly by the kidneys through urine. Urea levels in body fluids, such as blood and saliva, rise drastically under certain kidney dysfunctions. Heart failure, hypovolemic shock, gastrointestinal bleeding, and severe infections can also lead to a rise. Thus urea in blood and saliva provides key information on renal function and helps diagnose various disorders. Most methods for estimating urea in body fluids are based on colorimetry. These methods are time-consuming and involve painful blood extraction. Collecting saliva is non-evasive and research has correlated salivary and blood urea levels. Recently scientists from the IIT-D and the AIIMS, New Delhi successfully developed a smartphone-based optical biosensor to detect urea in saliva. To fabricate the sensor, they directly immobilised the urease enzyme with a pH indicator on a filter paper-based strip. As a response to the urea on saliva, the paper strip changes colour. The red, green and blue levels help measure urea concentration. The scientists used the slope method, sensor response change per unit time, instead of the differential method, the difference in sensor response between two-time intervals, to increase sensitivity and eliminate interference by variations in ambient light. The team clinically validated spiked saliva samples and samples from healthy volunteers. The smartphone application with paper strip can even be operated by non-professional with limited training. This saves time and cost spent on bulky spectroscopic procedures. The report can revolutionise the medical screening of large populations. And such mass screening of diseases would boost national health. |
A2. Complete the following sentence using the correct alternatives from those given below :
Two objectives to conduct the research are ___________ .
(i) The colorimetry method used to estimate urea in body fluids consumes more time.

- ______
We give undue importance to our health and the treatment of diseases. A large number of medicines treat only the symptoms of the disease, and not the root cause. In fact, the cause of many chronic ailments is still being researched. It is here that Yoga therapy comes to our assistance. Yoga emphasizes the treatment of the root cause of an ailment. It works in a slow, subtle and miraculous manner. Modern medicine can claim to save a life at a critical stage, but, for complete recovery and regaining of normal health, one must believe in the efficiency of Yoga therapy.
The Yogic way of life includes a code of ethics, regulations, discipline, combined with prayer and meditation. Even a discussion of these subjects helps one relieve mental tensions and change attitudes. Simple Asana has helped to stretch and relax the whole body and release tensions. The sincere practice of Yoga postures is beneficial, for the mind and body.
The continued practice of Yoga has a profound effect on the inner dimensions of life. Yoga aims at developing mental, physical, spiritual, and emotional facilities. Other forms of physical exercises, like aerobics, assure only physical well-being. They have little to do with the development of the soul and mind.

Read the following passage and answer the questions that follow:
| 1. |
Too many parents these days can't say no, As a result, they find themselves raising 'children' who respond greedily to the advertisements aimed right at them. Even getting what they want doesn't satisfy some kids; they only want more. Now, a growing number of psychologists, educators, and parents think it's time to stop the madness and start teaching kids about what's really important: values like hard work, contentment, honesty, and compassion. The struggle to set limits has never been tougher and the stakes have never been higher. One recent study of adults who were overindulged as children paints a discouraging picture of their future: when given too much too soon, they grow up to be adults who have difficulty coping with life's disappointments. They also have a distorted sense of entitlement that gets in the way of success in the workplace and in relationships. |
| 2. |
Psychologists say that parents who overindulge their kids set them up to be more vulnerable to future anxiety and depression. Today's parents themselves raised on values of thrift and self-sacrifice, grew up in a culture where no was a household word. Today's kids want much more, partly because there is so much more to want. The oldest members of this generation were born in the late 1980s, just as PCs and video games were making their assaults on the family room. They think of MP3 players and flat-screen TV as essential utilities, and they have developed strategies to get them. One survey of teenagers found that when they crave something new, most expect to ask nine times before their parents give in. By every measure, parents are shelling out record amounts. In the heat of this buying blitz, even parents who desperately need to say no find themselves reaching for their credit cards. |
| 3. |
What parents need to find, is a balance between the advantages of an affluent society and the critical life lessons that come from waiting, saving, and working hard to achieve goals. That search for balance has to start early. Children need limits on their behaviour because they feel better and more secure when they live within a secure structure. |
| 4. |
Older children learn self-control by watching how others, especially parents act. Learning how to overcome challenges is essential to becoming a successful adult. Few parents ask kids to do chores. They think their kids are already overburdened by social and academic pressures. Every individual can be of service to others, and life has meaning beyond one's own immediate happiness. That means parents eager to teach values have to take a long, hard look at their own. |
Based on your understanding of the passage, answer any eight questions from the nine given below:
- What is challenging for today's parents?
- What will be the consequence of over indulging children?
- Why do parents get caught in the buying blitz?
- How do children learn critical life lessons?
- What is the impact of advertisements on children?
- Why do children need limits on their behaviour?
- How do older children learn self-control?
- Find a word in the passage which means 'research'. (Paragraph 2)
- Find a word in the passage which means 'wealthy'. (Paragraph 3)

Read the following passage carefully:

(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?
