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 i.e., 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'.

Read the following passage carefully : (1) With the growing focus on sustainable living, the importance of kitchen gardens in urban regions has garnered greater acknowledgement. One significance of kitchen gardens in urban areas is their role in promoting food security. Rapid urbanization has led to increased distances between food production centres and urban settlements, resulting in longer food supply chains and a decrease in the freshness and nutritional value of food. (2) By having a kitchen garden, urban dwellers can grow their own fresh produce at home, making good use of empty tins, old utensils, and clay flower pots, ensuring a constant supply of nutritious food for themselves and their families. This activity not only saves money and time but can also provide a healthy, practical, and environmentally friendly hobby for the whole family. (3) Not only do kitchen gardens contribute to food security, but they also play a crucial role in environmental sustainability. Traditional agricultural practices often involve the use of synthetic fertilizers, pesticides, and intensive irrigation methods, which may have adverse effects on the environment. However, kitchen gardens promote organic farming, reducing the use of harmful chemicals and preserving soil health. (4) In addition to fostering a sustainable environment, kitchen gardens provide numerous health benefits to urban dwellers. The availability of fresh and organic produce from the garden ensures a higher intake of essential nutrients, vitamins, and minerals, promoting better overall health and well-being. (5) Furthermore, kitchen gardens have proven to be an effective tool for education and community development. They provide an opportunity for individuals to reconnect with nature and learn about the basics of agriculture. Besides providing fruits and vegetables, gardening provides an aesthetic and therapeutic exercise that helps relieve stress. The physical activity involved in tending to a garden helps individuals stay active, reducing the risk of obesity and related health issues. (6) By involving children in gardening activities, they can develop an appreciation for the environment and learn essential life skills. Moreover, kitchen gardens can also serve as a platform for community engagement, fostering social interactions and promoting a sense of belonging among urban residents. (7) Despite the numerous benefits of kitchen gardens, establishing and maintaining one in urban areas can be challenging. Limited space, lack of sunlight, and soil quality issues are common obstacles that urban gardeners face. However, innovative solutions such as vertical gardening, hydroponics, and rooftop gardens have emerged to overcome these challenges. (8) It is imperative to provide support and resources to encourage urban gardening initiatives as this can transform urban areas into sustainable havens where residents not only live but thrive in harmony with nature.

Read the following passage carefully : (1) Silk is a natural protein fibre, some forms of which can be woven into textiles. Silk has a long history in India. It is known as Resham in eastern and northern India, and Pattu in the southern parts of India. India is the second largest producer of silk in the world after China. (2) Silk is renowned for its luxurious qualities with a natural soft and smooth texture that feels comfortable on the skin. One of its unique qualities is to absorb and release moisture, regulating the body temperature, and keeping the wearer cool and dry. (3) Silk is one of the strongest natural fibres, but it loses up to 20% of its strength when wet. Its elasticity is moderate to poor: if elongated even a small amount, it remains stretched. It can be weakened if exposed to too much sunlight. It may also be attacked by insects, especially if left dirty. (4) The process of silk production is known as sericulture. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. To produce 1 kg of silk, 104 kg of mulberry leaves must be eaten by 3000 silkworms. (5) So what makes silk so costly ? Firstly, cultivation of silk is a labour-intensive work. Secondly, the silk fabric is carefully derived from the larva of the silkworms which spin silk threads around themselves to make cocoons from natural sources. This makes the production limited due to factors like — climate, availability of quality mulberry leaves and time required by silkworms to complete their lifecycle. Thirdly, the intensive work can only be carried out with specialized knowledge and expertise by skilled artisans and craftsmanship. Lastly, superior quality silk fabrics are made from long and uniform silk fibres giving them a smooth and lustrous appearance. Thus, production requires careful selection, adding to the cost. In 2021, Karnataka was the highest producer of raw silk at 8483 metric tonnes followed by Andhra Pradesh at 5520 metric tonnes with Assam close behind at 5038 metric tonnes. At the other end of the spectrum there was Chhattisgarh (248 metric tonnes), Nagaland (230 metric tonnes) and UP trailed behind at 179 metric tonnes.

Read the following passage carefully : (1) Saffron is a spice that's long been revered across the globe, captivating hearts and palates with its deep-red hue and complex flavour. It is one of the most prized spices that you can find on this planet. Just like gold is among the most valuable metals in the world, saffron means the same in the world of spices. Also known as 'kesar' in Hindi, it has a rich history and is often called an ancient spice. Saffron is being used since ages in various foods made for the royals and the elite as it contains medicinal properties. (2) Originating from the delicate stigma of the saffron crocus flower, it transforms the ordinary into the extraordinary, infusing dishes with a subtle, earthy sweetness that adds a special taste to the palate. Saffron has a strong exotic aroma and a unique flavour and is used to colour and flavour many Mediterranean and Asian dishes, particularly rice, fish and English, Scandinavian, and Balkan breads. (3) Saffron forms the backbone of several iconic dishes from around the world, such as the Spanish rice, seafood dish Paella, the French stew Bouillabaisse, Italian rice dish Risotto Milanese, the Indian ice cream Kesar Kulfi, Pakistani rice dish Biryani, and baked Iranian rice Tachin. Saffron's rich red colour is attributed to crocin; its bitter taste, to picrocrocin; and its distinctive aroma, to safranal. (4) Saffron is cultivated chiefly in Iran but is also grown in Spain, France, Italy, and parts of India. A labour-intensive crop, the three stigmas are handpicked from each flower, spread on trays, and dried over charcoal fires for use as a food flavouring and colouring agent. (5) Most historians speculate it was first domesticated in Iran, but south-western Greek islands remain strong contenders. Traders, conquerors, and world explorers introduced it to China, India and the Middle East. From there, it travelled to Mediterranean Europe. (6) The high retail value of saffron is maintained in world markets because of labour-intensive harvesting methods, which require some 444,000 hand-picked saffron stigmas per kilogram — equivalently, 150,000 crocus flowers per kilogram. Forty hours of labour are needed to pick 150,000 flowers. Almost all saffron grows in a belt from Spain in the west to India in the east. Iran is responsible for around 88% of global production. Afghanistan comes second, and Spain is the third largest producer, while the United Arab Emirates, Greece, the Indian subcontinent and Morocco are among minor producers. (7) Given its high price, adulteration is quite common, unfortunately. Adulterants like beetroot or pomegranate are used to enhance red colour; silk fibres, oil, or wax are used to add bulk, and powdered saffron can be adulterated with turmeric and paprika.

Read the following passage carefully : (1) Cinnamon is a spice obtained from the inner bark of several tree species from the genus Cinnamomum. Cinnamon is made by cutting the stems of cinnamon trees. The inner bark is then extracted and the woody parts removed. When it dries, it forms strips that curl into rolls, called cinnamon sticks. These sticks can be ground to form cinnamon powder. The spice, consisting of the dried inner bark, is brown in colour and has a delicately fragrant aroma and a warm sweet flavour. The distinct aroma and flavour of cinnamon derive from its essential oil and principal component, cinnamaldehyde, as well as numerous other constituents including eugenol. (2) There are two main types of cinnamon: Cassia and Ceylon. The two have different nutritional profiles. Ceylon cinnamon comes from Sri Lanka. Some people call it "true cinnamon." Cassia cinnamon, on the other hand, originates from southern China. Cassia is cheaper than Ceylon cinnamon. Cassia cinnamon has a robust, rich, somewhat bitter flavour while Ceylon is sweeter and lighter in flavor. (3) Cinnamon was once more valuable than gold. In Egypt it was sought for embalming and religious practices. In medieval Europe it was used for religious rites and as a flavouring agent. Later it was the most profitable spice in the Dutch East India Company trade. (4) Cinnamon is widely used as an aromatic condiment and flavouring additive in a wide variety of cuisines, sweet and savoury dishes, breakfast cereals, snack foods, bagels, teas, hot chocolate and traditional foods. (5) Cinnamon is a spice that has been prized for its medicinal properties for thousands of years. In recent years, modern science has started to confirm many of the potential health benefits associated with cinnamon. Cinnamon has antimicrobial and antifungal properties, which is why it's often found in dental-hygiene products and is sold as cinnamon supplements. It is also a good source of antioxidants, substances that inhibit the effect of free radicals (reactive atoms that can damage cells). Due to its anti-inflammatory nature, cinnamon is currently being researched for its potential to fight Alzheimer's disease and decrease symptoms of irritable bowel syndrome and colon cancer. (6) Studies also suggest that cinnamon has anti-diabetic properties, and may offer protection from cancer and cardiovascular disease, among other conditions. However, more evidence is needed to confirm cinnamon's benefits. In the short term, consuming moderate amounts of cinnamon as a spice or as a supplement seems to be safe for most people. However, cinnamon contains coumarin. This is a natural flavouring, but it also plays a role in creating warfarin, the common blood-thinning drug. Consuming too much coumarin can lead to liver damage and affect coagulation.

Read the following passage carefully : (1) When planning vacations, Indians typically prioritize domestic destinations, as shown by Ministry of Tourism data indicating 1.7 billion domestic tourist visits within India compared to 21 million international departures in 2022. Uttar Pradesh, Rajasthan, Tamil Nadu, Andhra Pradesh, and Karnataka stand out as the top states for domestic tourism. Reasons for domestic tourism are many, some travel because it suits their budget while others love to explore the historical, cultural diversity. The government today is focussing on tourist-friendly infrastructure which is making travel more convenient for the domestic traveller. (2) In terms of outbound tourism, a significant proportion of Indian travellers, totalling 5.9 million, visited the United Arab Emirates in 2022, comprising 28 percent of total outbound tourist travel. Other Gulf states such as Saudi Arabia, Qatar, and Kuwait also rank among the top destinations, with 2.4 million, 880,000, and 830,000 Indian visitors, respectively. Additionally, countries like the United States and the United Kingdom attract a considerable number of Indian tourists because these countries offer a mix of traditional and contemporary experiences along with enjoying unique cuisines and diverse landscapes. (3) The popularity of Gulf States and the U.S. may be influenced by migration trends. The current issue of the International Organization for Migration's (IOM) World Migration Report highlights significant migration flows from India to the United Arab Emirates, the United States, and Saudi Arabia. For instance, the Emirates hosted approximately 3.6 million Indian migrants as of August 2023. Only via two corridors have more people transferred from one country to another as of 2020 according to the IOM: Mexico to the United States with around 11 million and Syria to Turkey with approximately 4 million. These migration corridors rank among the top ten globally.
