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. |

A3. Make antonyms of the following words using prefix: (2)
- different × ______
- experience × ______
- bacterial × ______
- natural × ______
A4. Do as directed: (2)

उत्तर
A1.
A2. Fireflies are preserved because the biochemical processes they go through are important for detecting bacterial contamination in food and testing anti-cancer medications, among other things. Oxygen, calcium, magnesium, and luciferin are also carried by fireflies.
A3.
- different × indifferent
- experience × inexperience
- bacterial × anti-bacterial
- natural × unnatural
A4. (i) Many people can disturb adult as well as larval habitat.
(ii) to produce
A5. Insect pollinators, such as bees, help with propagation and fruit production. They are also pest predators or parasites. Aside from that, they provide honey. Bees work extremely hard. They frequently work themselves to death. This is a source of inspiration for humans. They teach us to never give up, even when the odds are stacked against us.

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 natural life span of a domesticated horse is about 25 – 30 years, 10 years down from what it was in the wild. You can tell a horse’s age from the number of teeth he has. They get all their teeth by the age of 5, after which those teeth just get longer. Horses have close to 360 degree all round vision. The only place they cannot see is directly behind or right in front of themselves, which is why it’s dangerous to stand behind a horse. If they later I it also means that they cannot see a jump once they are about four feet from it, and have to rely on memory as to its height and shape! Each of the horse’s two eyes work independently wherever a horse’s ear points is where the horse is looking. A horse is able to sleep standing up as he is able to lock his leg muscles so that he dosen’t fall asleep. Nor do all horses in the same field ever lie down at once – one animal always stands “on look out” duty.

Read the following passage:
In India, eating organic food is more of a style statement than due to health worries because the stuff is expensive. But people who can, do indulge in not only organic vegetables but even organic eggs laid by 'happy hens', who are allowed to roam around freely whereas 'unhappy hens' are kept in coops. Then there are companies that have installed music channels in their cowsheds and the milk from those sheds are sold at a marked up price since it has more nutritional value because the animals are happy thanks to lilting 24×7 music. We don't know yet any farmer using music to improve his crop quality, but then you never know : plants are known to respond to music.
Why such pickiness about food ? These days, the huge number of TV shows and articles that we see and read on food provide bread and butter for the specialist. But instead of decoding food, its sources and what has gone into growing it, isn't it much better to enjoy what's on the plate ?

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?
(3) Why is it necessary to update our city development plan?
(4) Do you think unplanned cities make the life of its people
miserable? How?
(5) Rewrite the following sentences in the ways instructed :
(i) A city must provide equity and also be sustainable.
(Rewrite the sentence using 'not only ...... but also'.)
(ii) Many of our cities have good master plans.
(Frame a Wh-question to get the underlined part as its answer.)
(iii) It needs to preserve and protect its heritage.
(Identify the tense used in the sentence.)
(6) Find out from the extract the words which mean:
(i) practical
(ii) blend
Read the following extract and answer the questions given
below :
In 1945 in Bay Roberts, Canada, a 12-year-old boy saw something in a shop window that set his heart racing. But the price -five dollars-was far beyond Reuben Earle's means. Five dollars would buy almost a week's groceries for his family.
Reuben couldn't ask his father for the money. Everything Mark Earle made by fishing, Reuben's mother, Dora, stretched like elastic to feed and clothe their five children.
Nevertheless, he opened the shop's weathered door and went inside. Standing proud and straight in his flour-sack shirt and washed out trousers, he told the shopkeeper what he wanted, adding, "but I don't have the money now. Can you please hold it for me?" ·
"I will try," the shopkeeper smiled. ''Folks around here don't usually have that kind of money to spend on things. It should keep for a while.,.
Reuben respectfully touched his worn cap and walked out into the May sunlight. The bay rippled in a freshening wind that ruffled his short hair. There was purpose in his loping stride. He
would raise the five dollars and not tell anybody.
Hearing the sound of hammering from a side street, Reuben had an idea.
He ran towards the sound and stopped at a construction site. People built their own homes in Bay Roberts, using nails purchased in burlap sack from a local factory. Sometimes the sacks were discarded in the flurry of buildings, and Reuben knew he could sell them back to the factory for five cents a piece.
(1) What did Reuben decide to do to raise the required amount?
(2) How much money did Reuben need? Why?
(3) Why couldn't Reuben ask his father for the money?

We were an argrarian people. And my main hobby in my early teens was to wander through paddy field to see the different kinds of birds and how they nest. On the outskirts of the paddy fields, there had been many coconut trees and black palm trees. Beautifully crafted nests of the weaver-birds thookkanaam kuruvikal-would be seen dangling from the ends of palm leaves. Hundreds of these little birds would land on the paddy to squeeze the milk from the tender rice. They would come to the fields when the young stalks come out of the rise-plants. At this stage of the paddy, my father would send me to our field with a tin drum to scare these birds away. But often I have enjoyed the sight of these little birds balancing on the tender stalks and squeezing the milk out of the green rice. When the paddy is ripe enough to harvest, flocks of parrots would land there and cut the ripe stalks with their sharp beaks and fly away with the stalks dangling in their beaks. I have always liked to see this sight also.
The nest of parrots were neatly crafted holes in the trunks of palm trees. I continued to wonder how they made chose holes on the hard trunks until I saw the patient work of the woodpeckers. They were the carpenters and their long, sharp and strong beaks, chisels. They make the holes (in search of worms inside the weak spots of the trunks) and the parrots occupy them. If I heard the sound tak, tak, tak. I knew it was a woodpeckers chiselling a had trunk. I would go after him. It seems that the woodpecker is the only bird which can walk perpendicularly on the tree trunks! How beautiful the sight was! Its strong legs, red crest, the dark red stripe on the face and black beak and the tak, tak, tak sound used to captivate me

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.

Technology is making advancements at a rapid rate but at the cost of a valued tradition - the crafts industry. The traditional crafts industry is losing a lot of its trained and skilled craftsmen. With that, the art of embellishing brass and copper utensils with fine engravings is also disappearing. The government has identified around 35 crafts as a languishing craft. |
|
10 |
The speciality of handcrafted items is their design, an association with long traditions belonging to a specific region. The word ‘handcrafted’ does not imply the involvement of dexterous human fingers or an agile mind with a moving spirit anymore. Lessening drudgery, increasing production and promoting efficiency have taken precedence. The labour-saving devices are taking the place of handcrafted tools and this has jeopardized the skills of these artisans. |
|
15 |
Mechanisation has made its way into everything - cutting, polishing, edging, designing etc. Ideally, the use of machinery should be negligible and the handicrafts should be made purely by hand with a distinguishable artistic appeal. However, with the exception of small-scale industries, the export units are mostly operated by machines. The heavily computerised designs contribute to faster production at lower costs. |
|
20 |
Although mechanization of crafts poses a challenge to safeguarding traditional crafts, the artisans are lured with incentives in order to impart handicrafts training. Some makers do see machines as a time-saving blessing since they are now able to accomplish difficult and demanding tasks with relative ease. These machines might give a better 25finesse to these products but they don’t stand out as handcrafted. The quantity has overtaken quality in this industry. |
|
30 |
A need to highlight the importance of the handmade aspect is required by both the government and private sectors, in order to amplify awareness and also support the culture of making handicrafts. A few artisans are still trying their best to rejuvenate and revive their culture and heritage but it’s an uphill task competing with the machine-made goods. A multitude of artisans have changed their professions and are encouraging their progeny to follow suit. There are others who have stayed their ground but are clearly inclined towards buying machines. |
|
35 |
Nearly two decades ago, there were around 65 lakh artisans in the country. Three years ago, when the government started the process of granting a unique number to the artisans based on the Aadhaar card, 25 lakhs were identified. Loss of traditional crafts is clearly a worrying issue, but it stands to reason that forcing any artisan to follow old ways when concerns of livelihood overrule other considerations, is unfair. |
Based on your understanding of the passage, answer the questions given below.
- What does the writer mean by calling handicrafts a ‘valued tradition’?
- Rewrite the following sentence by replacing the underlined phrase with a word that means the same from lines 5-15.
If it continues, the workcation (work + vacation) trend will be a powerful boost to domestic tourism operators failing to make progress in the economic slump caused due to the pandemic. - State any two reasons why artisans are choosing to work via machines rather than handcrafted tools.
- Why do the artisans need to be ‘lured with incentives’ to impart handicrafts training?
- List one likely impact of the support of government and private sectors towards the culture of making handicrafts.
- How does the writer justify an artist’s act of abandoning her/his traditional craft for a more lucrative option?
Based on the careful reading of the passage given below, answer any four out of five questions that follow:

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’. |
