Read the following passage carefully:
(1) In recent years, air pollution has emerged as one of the most pressing environmental and public health issues in India. Cities like Delhi, Mumbai and Bengaluru often record Air Quality Indices (AQI) that fall into the ‘hazardous’ category, posing several health risks to their inhabitants. The thick blanket of smog that shrouds these urban areas is composed of harmful pollutants such as particulate material (PM 2.5 and PM 10), nitrogen dioxide (NO₂) and sulphur dioxide (SO₂). These pollutants originate from various sources including vehicular emissions, industrial activities and construction dust.
(2) The constant emission of pollutants from vehicles, industrial activities and construction works exacerbate the problem. Residents of these cities are often seen wearing masks and using air purifiers in a desperate attempt to mitigate the effects of polluted air. The ‘urban haze’ not only affects physical health but also impacts mental well-being. Studies indicate that prolonged exposure to high pollution levels can lead to respiratory issues, such as cardiovascular diseases and even cognitive decline.
(3) Furthermore, children and the elderly are the most vulnerable groups. Children, with their developing respiratory systems, and the elderly, often with pre-existing health conditions, face the brunt of this environmental crisis. Schools frequently shut down during peak pollution periods, disrupting education and daily life. The economic cost of air pollution is staggering, with increased healthcare expenses and lost labour productivity. Businesses also suffer as employees’ health issues lead to increased absenteeism and decreased efficiency.
(4) Government initiatives, such as the National Clean Air Programme (NCAP), aim at reducing air pollution levels across the country. However, these measures require robust implementation and public cooperation to be effective. Simple actions like reducing vehicle use, promoting public transportation and adopting cleaner technologies can significantly alleviate the situation. Additionally, the enforcement of stricter emission norms for industries and vehicles is crucial. Public awareness campaigns can play a pivotal role in encouraging others to adopt environmentally friendly practices.
(5) The role of technology in combating air pollution is also noteworthy. Innovative solutions such as air quality monitoring systems, green buildings and electric vehicles are gaining attraction. These technologies not only help in reducing pollution but also promote sustainable development. Urban planning that incorporates green spaces can also mitigate the effects of pollution by improving air quality and providing residents with a healthier living environment.
(6) As we navigate this challenge, it is imperative to remember that the solution lies not just in policy changes but also in the behavioural shifts of individuals. Embracing a lifestyle that prioritizes environmental health will pave the way for a cleaner, healthier India. Collective efforts and sustained commitments are crucial for ensuring breathable air for future generations. It is a shared responsibility that requires action from every segment of society, from policymakers to ordinary citizens.

(1) Pancakes, a beloved breakfast dish across the world, has a surprisingly long and diverse history. Archaeological evidence shows that people were cooking pancakes as food as far back as 30,000 years ago on hot stones and primitive griddles.
(2) In ancient Greece and Rome, pancakes were made from wheat flour, olive oil, honey, and curdled milk. They were often served as a sweet treat during festivals or special occasions. In medieval Europe, pancakes became a popular dish during Shrove Tuesday, the day before Lent began. In France, thin crepes became a national delicacy, often filled with sweet or savoury ingredients. In Russia, blinis were made using buckwheat flour and served with sour cream or caviar. In Ethiopia, the spongy injera became a staple food, made from teff flour and used as both a plate and utensil. Similarly, in China, pancakes are often savoury while in Japan, fluffy “souffl´ e pancakes” have become a modern favourite.
(3) The American version of pancakes, thick and soft, gained popularity in the 18th century. The use of baking powder made them light and airy, and they were often served with butter and maple syrup– a symbol of hearty comfort food. Over time, pancakes became a universal dish, symbolizing community and celebration. Whether sweet or savoury, thick or thin, every culture has found a way to adapt this simple food to its own taste and traditions.
(4) India has its own rich tradition of similar dishes that have been enjoyed for centuries. Across the country, almost every region has a version of a pancake– whether sweet or savoury– made from grains, pulses, or rice. These Indian pancakes not only satisfy hunger but also reflect the diversity of India’s culinary culture. In South India, dosas and adai are the most famous forms of pancakes. Made from a fermented batter of rice and lentils, dosas are crisp and light, while adai is thicker and more filling. The fermentation process adds a unique sour flavor and makes them nutritious and easy to digest. In Kerala, the appam, made with fermented rice batter and coconut milk, is soft in the center and crispy at the edges. Moving north, we find the western style cheela, a simple and wholesome Indian pancake made from gram flour, spiced with onions, chillies and coriander. In Maharashtra, the thalipeeth is a multigrain pancake that uses flours like jowar, bajra and rice mixed with spices and vegetables. It is both flavorful and filling, providing a good balance of carbohydrates and proteins.
(5) In the eastern parts of India, pitha is a traditional pancake made during festivals and special occasions. Varieties like patishapta in Bengal are sweet, filled with coconut and jaggery. In Assam and Odisha, pithas can be steamed, fried, or roasted, depending on the custom and region. In the western deserts of Rajasthan and Gujarat, people prepare chilla and handvo, which are savoury western pancake-like dishes baked in traditional ovens. These pancakes are a blank canvas for toppings, waiting for a splash of fruit or a scattering of condiments.
(6) Today, pancakes continue to evolve with new recipes, from vegan and gluten-free varieties to those infused with fruits, oats, or even protein powder. Despite their many forms, they remain a timeless reminder of how food connects mankind through shared history and creativity. Each pancake tells a story of regional identity, food traditions and a deep love for food that brings people together. Pancakes are warm, edible hugs that are a perfect comfort on a bleak day.- CBSE Class X - 2026

(1) Rate of Internet Reach in India : 2014–2024
The rate of internet reach in India rose over 52% in 2024 from about 14% in 2014. Although these figures seem relatively low, it meant that more than half of the population of 1.4 billion people had internet access that year. This also ranked the country second in the world in terms of active internet users.
(2) Internet availability and accessibility By 2021 the number of internet connections across the country tripled in urban areas because of a higher density of population leading to an increase in the number of connections. However, despite of incredibly low internet prices, internet usage in India has yet to reach its full potential. Lack of awareness about the internet in India persists, especially in rural areas and among women, driven by digital divide, infrastructure limitations, and a lack of perceived need for the internet. This hinders digital adoption, with many not knowing how to use the internet or even being aware of its existence. Targeted awareness campaigns and digital literacy programs are crucial to bridge this gap and ensure people understand and can benefit from the digital ecosystem.
(3) Digital living Home to one of the largest bases of netizens in the world, India is abuzz with internet activities being carried out every moment of every day. From information and research to shopping and entertainment to living in smart homes, Indians have welcomed digital living with open arms.
