Question
Read the extract given below:
| (1) | Necessity is indeed the mother of invention. When areas in and around Leh began to experience water shortages, life didn't grind to a halt. Why? Because a retired civil engineer in the Jammu and Kashmir Government came up with the idea of artificial glaciers. |
| (2) | Ladakh, a cold desert at an altitude of 3,000 - 3,500 meters above sea level, has a low average annual rainfall rate of 50 mm. Glaciers have always been the only source of water. Agriculture is completely dependent on glacier melt, unlike the rest of river/monsoon-fed India. But over the years, with increasing effects of climate change, rainfall and snowfall patterns have been changing, resulting in severe shortage and drought situations. Given the extreme winter conditions, the window for farming is usually limited to one harvest season. |
| (3) | It is located between the natural glacier above and the village below. The one closer to the village and lowest in altitude melts first, providing water during April-May, the crucial sowing season. Further, layers of ice above melt with the increasing temperature, thus ensuring continuous supply to the fields.
Therefore, farmers have been able to manage two crops instead of one. It costs about 1,50,000 and above to create a glacier. |
| (4) |
Fondly called the glacier man, he has designed over 15 artificial glaciers in and around Leh since 1987. In recognition of his pioneering effort, he was conferred the Padma Shri by The President of India. |
| (5) |
There are a few basic steps followed while creating an artificial glacier. River or stream water at high altitude is diverted to a shaded area of the hill, facing north, where the winter sun is blocked by a ridge or a mountain range. At the start of winter ie., in November, the diverted water is made to flow on sloping hills facing distribution channels. Stone embankments are built at regular intervals which impede the flow of water, making shallow pools which freeze, forming a cascade of ice along the slope. Ice formation continues for 3-4 months resulting in a large accumulation of ice which is referred to as an ‘artificial glacier’. |

Solution
- because the idea of artificial glaciers was proposed by a retired civil engineer in the Jammu and Kashmir government.
- Agriculture is completely dependent on glaciers melt unlike the rest of river/monsoon-fed India.
- Icing : cake :: layers : Ice.
- At the start of winter the diverted water is made to flow on sloping hills facing distribution channels.
- July, August, September.
- The glaciers have been the only source of water in areas in and around Ladakh.
- situated
- Any two steps taken while creating glaciers include diverting stream water to a shaded area of a north-facing hill. At the start of winter, this water is made to flow on sloping hills facing distribution channels.
- Due to extreme weather conditions, farming is limited to the harvest season; thus, artificial glaciers appear to be the best option.

One of the greatest advances in modern technology has been the invention of computers. They are widely used in industries and in universities. Now there is hardly any sphere of human life where computers have not been pressed into service of man. We are heading fast towards the day when a computer will be as much part of man's daily life as a telephone or a calculator.
Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put thousands of unrelated facts in order. These machines can be put to varied uses. For instance, they can provide information on the best way to prevent traffic jams. This whole process by which machines can be used to work for us has been called 'automation'. In the future 'automation' may enable human beings to enjoy more leisure than they do today. The coming of automation is bound to have important social consequences.
Some years ago an expert on automation, Sir Leon Bagrit, pointed out that it was a mistake to believe that these machines could 'think'. There is no possibility that human beings will be "controlled by machines". Though computers are capable of learning from their mistakes and improving on their performance, they need detailed instructions from human beings to operate. They can never, as it were, lead independent lives or "rule the world" by making decisions of their own.
Sir Leon said that in future, computers would be developed which would be small enough to carry in the pocket. Ordinary people would then be able to use them to obtain valuable information. Computers could be plugged into a national network and be used like radios. For instance, people going on holiday could be informed about weather conditions. Car drivers can be given alternative routes when there are traffic jams. It will also be possible to make tiny translating machines. This will enable people who do not share a common language to talk to each other without any difficulty or to read foreign publications.

Read the passage given below:
1. Every morning Ravi gives his brain an extra boost. We're not talking about drinking strong cups of coffee or playing one of those mind-training video games advertised all over Facebook. "I jump onto my stationary bike and cycle for 45 minutes to work," says Ravi. "When I get to my desk, my brain is at peak activity for a few hours." After his mental focus comes to a halt later in the day, he starts it with another short spell of cycling to be able to run errands.
2. Ride, work, ride, repeat. It's scientifically proven system that describes some unexpected benefits of cycling. In a recent study in the Journal of Clinical and Diagnostic Research, scientists found that people scored higher on tests of memory, reasoning, and planning after 30 minutes of spinning on a stationary bike than they did before they rode the bike. They also completed the tests faster after pedalling.
3. Exercise is like fertilizer for your brain. All those hours spent on exercising your muscles, create rich capillary beds not only in leg and hip muscles, but also in your brain. More blood vessels in your brain and muscles mean more oxygen and nutrients to help them work. When you pedal, you also force more nerve cells to fire. The result: you double or triple the production of these cells – literally building your brain. You also release neurotransmitters (the messengers between your brain cells) so all those cells, new and old, can communicate with each other for better, faster functioning. 'That's a pretty profound benefit to cyclists.
4. This kind of growth is especially important with each passing birthday, because as we age, our brains shrink and those connections weaken. Exercise restores and protects the brain cells. Neuroscientists say, "Adults who exercise display sharper memory skills, higher concentration levels, more fluid thinking, and greater problem-solving ability than those who are sedentary."
5. Cycling also elevates your mood, relieves anxiety, increases stress resistance, and even banishes the blues. "Exercise works in the same way as psychotherapy and antidepressants in the treatment of depression, maybe better," says Dr. Manjari. A recent study analyzing 26 years of research finds that even some exercise – as little as 20 to 30 minutes a day – can prevent depression over the long term.
6. Remember: although it's healthy, exercise itself is a stress, especially when you're just getting started or getting back into riding. When you first begin to exert yourself, your body releases a particular hormone to raise your heart rate, blood pressure, and blood glucose levels, says Meher Ahluwalia, PhD, a professor of integrative physiology. As you get fitter, it takes a longer, harder ride to trigger that same response.

Read the passage given below and answer the questions that follow:
The most alarming of man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with lethal materials. This pollution is for the most part irrevocable; the chain of evil it initiates is for the most part irreversible. In this contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world; radiation released through nuclear explosions into the air, comes to the earth in rain, lodges into the soil, enters the grass or corn, or wheat grown there and reaches the bones of a human being, there to remain until his death. Similarly, chemicals sprayed on crops lie long in soil, entering living organisms, passing from one to another in a chain of poisoning and death. Or they pass by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and harm those who drink from once pure wells.
It took hundreds of millions of years to produce the life that now inhabits the earth and reached a stage of adjustment and balance with its surroundings. The environment contained elements that were hostile as well as supporting. Even within the light of the sun, there were short wave radiations with power to injure. Given time, life has adjusted and a balance reached. For time is the essential ingredient, but in the modern world is no time.
The rapidity of change and the speed with which new situations are created follow the heedless pace of man rather than the deliberate pace of nature. Radiation is no longer the bombardment of cosmic rays; it is now the unnatural creation of man’s tampering with the atom. The chemicals to which life is asked to make adjustments are no longer merely calcium and silica and copper and all the rest of the minerals washed out of the rocks and carried in the rivers to the sea; they are the synthetic creations of man’s inventive mind, brewed in his laboratories, and having no counterparts in nature.

Read the passage given below:
People tend to amass possessions, sometimes without being aware of doing so. They can have a delightful surprise when they find something useful which they did not know they owned. Those who never have to change house become indiscriminate collectors of what can only be described as clutter. They leave unwanted objects in drawers, cupboards, and attics for years in the belief that they may one day need them. Old people also accumulate belongings for two other reasons, lack of physical and mental energy, and sentiment. Things owned for a long time are full of associations with the past, perhaps with the relatives who are dead, and so they gradually acquire a sentimental value.
Some things are collected deliberately in an attempt to avoid wastage. Among these are string and brown paper, kept by thrifty people when a parcel has been opened. Collecting small items can be mania. A lady cuts out from newspaper sketches of model clothes that she would like to buy if she had money. As she is not rich, the chances are that she will never be able to afford such purchases. It is a harmless habit, but it litters up her desk.
Collecting as a serious hobby is quite different and has many advantages. It provides relaxation for leisure hours, as just looking at one’s treasure is always a joy. One doesn’t have to go out for amusement as the collection is housed at home. Whatever it consists of - stamps, records, first editions of books, china – there is always something to do in connection with it, from finding the right place for the latest addition to verifying facts in reference books. This hobby educates one not only in the chosen subject but also in general matters which have some bearing on it.
There are other benefits also. One gets to meet like-minded collectors to get advice, compare notes, exchange articles, to show off one’s latest find. So one’s circle of friends grows. Soon the hobby leads to traveling, perhaps a meeting in another town, possibly a trip abroad in search of a rare specimen, for collectors are not confined to one country. Over the years one may well become an authority on one’s hobby and will probably be asked to give informal talks to little gatherings and then, if successful, to larger audiences.

Read the passage given below :
It is surprising that sometimes we don't listen to what people say to us. We hear them, but we don't listen to them. I was curious to know how hearing is different from listening. I had thought both were synonyms, but gradually, I realised there is a big difference between the two words.
Hearing is a physical phenomenon. Whenever somebody speaks, the sound waves generated reach you, and you definitely hear whatever is said to you. However, even if you hear something, it doesn't always mean that you actually understand whatever is being said. Paying attention to whatever you hear means you are really listening. Consciously using your mind to understand whatever is being said is listening.
Diving deeper, I found that listening is not only hearing with attention, but is much more than that. Listening is hearing with full attention, and applying our mind. Most of the time, we listen to someone, but our minds are full of needles chatter and there doesn't seem to be enough space to accommodate what is being spoken.
We come with a lot of prejudices and preconceived notions about the speaker or the the subject on which he is talking. We pretend to listen to the speaker, but deep inside, we sit in judgement and are dying to pronounce right or wrong, true or false, yes or no. Sometimes, we even come prepared with a negative mindset of proving the speaker wrong. Even if the speaker says nothing harmful, we are ready pounce on him with our own version of things.
What we should ideally do is listen first with full awareness. Once, we have done that, we can decide whether we want to make a judgement or not. Once we do that, communication will be perfect and our interpersonal relationship will become so much better. Listening well doesn't mean one has to say the right thing at the right moment. In fact, sometimes if words are left unspoken, there is a feeling of tension and negativity. Therefore, it is better to speak out your mind, but do so with awareness after listening to the speaker with full concentration.
Let's look at this in another way. When you really listen, you imbibe not only what is being spoken, but you also understand what is not spoken as well. Most of the time we don't really listen even to people who really matter to us. That's how misunderstandings grow among families, husbands and wives, brothers and sisters.

Read the following extract and answer the questions given
below:
Prominent among the urges that inspire and drive a person in life, is the mge to be a somebody. It is quite human, especially in the early stages of life, to want to do something to win laurels and admiration of all around. There's a pitfall though - the very process of becoming a somebody may subtly reduce yon to a nobody.
American poet Emily Dickinson, who lived in obscurity, has an interesting poem on this theme. "I'm nobody!" she declares, with apparent pride.
"Who are you?
Are you nobody, too?"
Why should anybody be happy about being nobody?
The poem explains :
"How dreaiy to he somebody!
How public, like a frog
To tell your name the livelong day
To an admiring bog!
The word 'bog' is significant. When you become a somebody, you invite adulation :
this then begins to bog you down. The moment you think you have arrived, you begin to stagnate, or, worse, your downslide begins. An endless list of writers, artists, sportsmen, politicians ..... fit this pattern of personal history.
To sustain your development in absolute terms, to become a true somebody, it is important to remain a temporal nobody. Even if destiny makes you a temporal somebody,
you should be able to see yourself as merely an agent of a superior power; no more. This requires an exercise of will. You have to constantly watch out and talk to yourself morning and evening.

But being named an 'AdarshGaon · is far from easy. Villages had to give a proposal after Which a committee headed by Mr. Pawar inspected the villages. "The villages had to show dedication in the struggle to fight mediocrity. They had to follow all the conditions of becoming an 'AdarshGaon '. We chose villages with a revolutionary spark." Mr. Pawar says.
Villages need to follow strict rules. The process begins with effective water managc1nent through the watershed technique and Water auditing. taking responsibility for the village's natural resources -phmting trees and stopping grazing, contributing labour for the village Work, and then expanding to bring about behavioral changes in the people for harbouring social change. Hiware Bazaar is free of any kind of addiction and there are no liquor or tobacco shops in the village. Vasectomy has been made co1npulsory. as is the pre-marital HIV test.
The 'AdarshGaon · n1odcl prides itself of being based on the joint decisions made by the (Gram Sabha, Where all the villagers are present. Even while selecting the new villages under the scheme, Mr. Pawar made sure that the decision to become an ideal village was taken by the entire village together.

A1. Complete the chart on the life stages of fireflies: (2)
|
Fireflies are beetles and go through several life stages, starting out as an egg, then hatching into larvae. At the juvenile stage, they turn into pupae and then, finally adults. Fireflies spend most of their lives in a larval stage, hidden away. There are 2000 different species of fireflies. But they all go through a long juvenile stage and a short adult life, which is mainly about courtship, mating and reproduction. The juveniles living underground or underwater, are very different though-they're hunters, they eat snails and soft-bodied insects and they have very different habitats. Conserving them is essential for human life as fireflies are a key part of the food web. They are predators of agricultural pests. In turn, they are prey for spiders and other insects. They are completely enmeshed in the web of life. In addition, about 70 years ago, scientists unravelled the mystery of fireflies' light-producing talents. Since then, the bio-chemical reactions that fireflies experience have been used in detecting bacterial contamination in foods, testing drugs against cancer, developing drought-resistant crops. They have been used in space exploration. So fireflies give us beauty and inventions. Fireflies carry oxygen, calcium, magnesium and a natural chemical called luciferin. These react together to produce the photons. This is how the fireflies glow. Firefly tourism is growing across the world. In Maharashtra, for example, a particular species monsoon fireflies, emerge before the rains. They're beautiful and a festival is held in Purushwadi, encouraging firefly tourism. Its wonderful that people around the world go to see fireflies in their natural habitat. We need to be cautious. Too many people can disturb adult and larval habitats. Fireflies need darkness to communicate with each other and we need fireflies because they are harbingers of hope. |

- Thousands of birds were killed due to oil spills because ______.
- It suffocated them
- It was poisonous
- Birds couldn't enter the sea
- There was no fish to feed on
- The primary components of crude oil are ______.
- Methane and ethane
- Carbon and hydrogen
- Sulphur compounds
- Naphthalene
| During the Gulf War, a few years back, tens of thousands of sea birds were killed due to oil spills. Do you know what makes crude oil on ocean water so deadly? Crude oil is not used in the state it is produced at the off-shore wells. It is converted in refineries into a wide range of products such as gasoline, kerosene, diesel, fuel oils, and petrochemical feed-stocks. Before it is refined, the oil also contains potentially fatal components. Crude oil is made up of compounds of carbon and hydrogen called hydrocarbons. These hydrocarbons may be paraffin, the oil that is used as fuel in heaters and lamps or cycloparaffins (naphthenes) or aromatic compounds in varying proportions. While crudes found in the US are mostly paraffinic, these found along the Gulf Coast are naphthenic which contain sulphur compounds in varying amounts, a small amount of nitrogen and very little oxygen. Every variety of crude oil has nickel and vanadium in high concentration. Iron may be found in organic form due to the corrosion of pipes. Paraffins like methane and ethane are asphyxiants, substances that cause suffocation. The effects of cycloparaffins are more or less similar to those of paraffins but unsaturated paraffins are more noxious, than saturated ones. The sulphur present in crude oil may be toxic. The mechanism of toxic action seems to involve its breakdown to hydrogen sulphide. They will act principally on the .nervous system with death resulting mainly from respiratory paralysis. Sulphur in the form of aromatic thiophenes, benzothiophenes can damage the livers and kidneys of sea animals. Sulphur compounds like mercaptens can be very dangerous too. |

Read the passage given below and answer the questions that follow:

1. The Higgs boson has been called, or miscalled, the God particle, enabling it to pass into the realm of popular scientific lore, like the discovery of the smallpox vaccine, the structure of DNA, or the theory of relativity. It would be difficult for most people to understand its significance, just as it would be to comprehend the notion of relativity, but such problems are overcome by locating science in personalities as well as cultural and national traditions. The first thing that you and I know about the Higgs boson is that it’s named after Peter Higgs, a physicist at Edinburgh University who made the discovery - although the original insight, in one of those recurrent back stories of science, was Philip Anderson’s. 2. Still, we have Higgs, and Edinburgh, and western civilisation to fall back on. The rest - “the Higgs boson is a hypothetical elementary particle predicted by the Standard Model of particle physics. It belongs to a class of particles known as bosons ...” - we needn’t worry too much about. But maybe we should worry just enough to ask, “What is a boson?” since the word tends to come up as soon as Higgs does. Is it, an ignoramus such myself would ask, akin to an atom or a molecule? It is, in fact, along with the fermion (named after Enrico Fermi), one of the two fundamental classes of subatomic particles. 3. From Bose The word must surely have some European genealogy. In fact, “boson” is derived from Satyendra Nath Bose, an Indian physicist from Kolkata who, in 1924, realised that the statistical method used to analyse most 19th-century work on the thermal behaviour of gases was inadequate. He first sent off a paper on quantum statistics to a British journal, which turned it down. He then sent it to Albert Einstein, who immediately grasped its immense importance, and published it in a German journal. Bose’s innovation came to be known as the Bose-Einstein statistics and became a basis of quantum mechanics. Einstein saw that it had profound implications for physics; that it had opened the way for this subatomic particle, which he named, after his Indian collaborator, “boson.” Still, science and the West are largely synonymous and coeval: they are words that have the same far-reaching meaning. Just as Van Gogh and Toulouse-Lautrec’s paintings digest the Japanese prints they were responding to so we don’t need to be aware of Japanese prints when viewing the post-impressionists, western science is pristine, and bears no mark of what’s outside itself. 4. Other Indian contributions The last Indian scientific discovery that is universally acknowledged is zero. Indians are very strong at maths, and the only modern Indian who’s remotely part of the western mythology of science is Srinivasa Ramanujan, equally well known for his Hindu idiosyncrasies and his agonised stay in Cambridge as he is for his mathematical genius. 5. Indians can be excellent geeks, as demonstrated by the tongue-tied astrophysicist Raj Koothrappalli in the U.S. sitcom Big Bang Theory; but the Nobel prize can only be aspired to by Sheldon Cooper, the super-geek and genius in the series, for whom Raj’s country of origin is a diverting enigma, and miles away from the popular myth of science on which Big Bang Theory is dependent. Bose didn’t get the Nobel Prize; nor did his contemporary and namesake, J.C. Bose, whose contribution to the fashioning of wireless predates Marconi’s. The only Indian scientist to get a Nobel Prize is the physicist C.V. Raman, for his work on a light at Kolkata University. Other Indians have had to become Americans to get the award. 6. Conditions have always been inimical to science in India, from colonial times to the present day; and despite that, its contributions have occasionally been huge. Yet non-western science (an ugly label engendered by the exclusive nature of western popular imagination) is yet to find its Rosalind Franklin, its symbol of paradoxical success. Unlike Franklin, however, scientists were never in a race that they lost; they simply came from another planet. |

Read the following text.
| (1) | As a high school student, studying poetry can be a rollercoaster ride. This journey is punctuated by moments of profound appreciation for simpler pieces and intermittent frustration with more complex works. Let's be real here -some poems are just plain confusing and no amount of re-reading seems to help decipher the intended meaning. The puzzlement that results from such instances can be both vexing and demotivating. If solving a riddle is what was intended, then playing Sudoku is a better option. One is led to ponder if obscurity was the goal. |
| (2) | Conversely, some pieces resonate with the reader's soul. Stirring feelings of warmth, happiness, and connection to the world. Often, these compositions centre on themes that are universally understood, such as love, nature, or faith. Being able to actually understand what the poet is trying to say can feel like a little victory and is a welcome relief after grappling with more perplexing poetry. |
| (3) | Then there are poems that are emotionally charged; the ones that make the reader curl up in a ball and cry or jump up and down with joy. One is left in awe of the poet's ability to convey emotion through words. Let’s not forget the downright weird poems. These are the ones that defy categorization and leave the reader to their own devices in attempting to interpret meaning. The author's use of figurative language and unconventional imagery can create a sense of bewilderment that is either intriguing or off-putting. Regardless, the reader can appreciate the uniqueness of the work. |
| (4) | Despite the wide range of emotions and reactions that come with studying poetry, it can be a rewarding pursuit. Not only does reading poetry allow one to appreciate the artistic beauty of the written word but also enables one to develop crucial critical thinking and analytical skills. The process of unlocking a poem's meaning can feel like cracking a code or solving a puzzle but the sense of accomplishment derived from mastering a challenging piece can be deeply gratifying. Finally, impressing an English teacher with a well-analysed poem can be a source of pride and validation. |
| (5) | Overall, studying poetry is like a box of mixed chocolates, you never know what you're going to get. But whether it's complex, emotional, simple, or just downright weird, there's always something to be gained from the experience. So, let's applaud all the poets out there, for making us laugh, cry, scratch our heads, and occasionally feel like a genius. |

Read the passage given below:
| (1) | Seagulls, as you know, never falter, never stall. To stall in the air is for them a disgrace and a dishonour. But Jonathan Livingston Seagull, unashamed, stretching his wings again in that trembling hard curve – slowing, slowing, and stalling once more –was no ordinary bird. Most gulls don't bother to learn more than the simplest facts of flight – how to get from shore to food and back again. For most gulls, it is not flying that matters, but eating. For this gull, though, it was not eating that mattered, but flight. More than anything else, Jonathan Livingston Seagull loved to fly. |
| (2) | This kind of thinking, he found, is not the way to make oneself popular with other birds. Even his parents were dismayed as Jonathan spent the whole day alone, making hundreds of low-level gliders, experimenting. "Why, Jon, why?" his mother asked. "Why is it so hard to be like the rest of the flock, Jon? Why can't you leave low flying to the pelicans, the albatross? Why don't you eat? Son, you're bone and feathers!" "I don't mind being bone and feathers, Mom. I just want to know what I can do in the air and what I can't, that's all. I just want to know." "See here Jonathan," said his father, not unkindly. "Winter isn't far away. Boats will be few, and the surface fish will be swimming deep. If you must study, then study food, and how to get it. This flying business is all very well, but you can't eat a glide, you know. Don't you forget that the reason you fly is to eat?" |
| (3) | Jonathan nodded obediently. For the next few days, he tried to behave like the other gulls; he really tried, screeching and fighting with the flock around the piers and fishing boats, diving on scraps of fish and bread. But he couldn't make it work. It wasn't long before Jonathan Gull was off by himself again, far out at sea, hungry, happy, learning. The subject was speed and in a week's practice he learned more about speed than the fastest gull alive. Time after time it happened. Careful as he was, working at the very peak of his ability, he lost control at a high speed. The key, he thought at last, dripping wet, must be to hold the wings still at high speeds – to flap up to fifty and then hold the wings still. |
| (4) | From two thousand feet he tried again, rolling into his dive, beak straight down, wings full out and stable from the moment he passed fifty miles per hour. It took tremendous strength, but it worked. In ten seconds he had blurred ninety miles per hour. Jonathan had set a world speed record for seagulls! But victory was short-lived. The instant he began his pullout, the instant he changed the angle of his wings, he snapped into the same uncontrollable disaster, and at ninety miles per hour, it hit him like dynamite. Jonathan Seagull exploded in midair and smashed down into a brick-hard sea. As he sank low in the water, a strange hollow voice sounded within him. There's no way around it. I am a seagull. I am limited by my nature. If I were meant to learn so much about flying, I'd have charts for brains. If I were meant to fly at speed, I'd have a falcon's short wings. Short wings. A falcon's short wings! That's the answer! What a fool I've been! All I need is a tiny little wing, all I need is to fold most of my wings and just fly on the tips along. Short wings! |

Read the passage given below:
| (1) | Fast-Moving Consumer Goods (FMCG) are products that sell quickly at relatively low cost. FMCG is the fourth-largest sector in the Indian economy. There are three main segments in the sector – food and beverages, which accounts for 19% of the sector; healthcare, which accounts for 31% of the share; and household and personal care, which accounts for the remaining 50% share. The urban segment contributes to about 55% of the revenue share, while the rural segment accounts for 45%. Rise in rural consumption will drive the FMCG market. The Indian processed food market is projected to expand to US\[\$\] 470 billion by 2025, up from US\[\$\] 263 billion in 2019-20. |
| (2) | The Indian FMCG industry grew by 16% in 2021, a 9-year high, despite nationwide lockdowns, supported by consumption-led growth and value expansion from higher product prices, particularly for staples. Real household spending is projected to increase 9.1% after 2021, after a decrease of 9.3% in 2020 due to the economic impact of the pandemic. Price increases across product categories will offset the impact of rising raw material prices, along with volume growth and a resurgence of demand for discretionary items. |
| (3) | The FMCG sector has received good investments and support from the Government in the recent past. The sector witnessed healthy FDI inflows from April 2000-March 2022. Furthermore, as per the Union Budget 2022-23, a substantial amount has been allocated to the Department of Consumer Affairs, and an increased amount has been allocated to the Department of Food and Public Distribution. In 2021-22, the Government approved the Production-Linked Incentive Scheme for the Food Processing Industry (PLISFPI) with an outlay of a larger amount to help Indian brands of food products in the international markets. |
| (4) | The Government's Production-Linked Incentive (PLI) Scheme gives companies a major opportunity to boost exports. The future outlook of the FMCG rural sector looks on track now. Rural consumption has increased, led by a combination of increasing income and higher aspiration levels. There is an increased demand for branded products in rural India. The growth of the organised sector in FMCG is expected to rise with an increased level of brand consciousness, augmented by the growth in modem retail. |

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. |
