2 only Explanation : Recently, there has been an increasing demand for Bollgard-3 in Punjab, ahead of the cotton sowing season. About Bollgard-3: It is a pest-resistant genetically-modified (GM) cotton variety. It was developed by Monsanto more than a decade ago, and shows remarkable resistance to pests. It contains three Bt proteins Cry1Ac, Cry2Ab and Vip3A that cause insect death by disrupting their normal gut function. This in turn allows for the growth of a healthier cotton crop, and increases yield. Farmers are demanding the introduction of Bollgard-3, which is particularly effective against lepidopteran pests like pink bollworm. Bollgard-1 was a Monsanto-developed Bt cotton introduced in India in 2002, followed by Bollgard-2 in 2006. The latter remains prevalent today. And although these do have some pest-repellent properties, they are not effective against the whitefly and the pink bollworm, which arrived in Punjab in 2015-16 and 2018-19 respectively. What is Bacillus thuringiensis? Bacillus thuringiensis (Bt) is a soil-dwelling bacterium with potent insecticidal properties. In the past few decades, researchers have successfully inserted certain genes from Bt in various crops, like cotton, providing these with insect-repellent properties. Hence only statement 2 is correct. News: https://indianexpress.com/article/explained/explained-economics/cotton-crisis-punjab-bt-cotton-regulatory-bollgard-9866415/

Only two Explanation : According to recent study, seagrass has been declining at a rate of 1-2 per cent per year for the past century and nearly 5 per cent of species are now endangered. About Seagrass: It is a flowering plant that grows submerged in shallow marine waters like bays and lagoons. It is so-named because most species have long green, grass-like leaves. Characteristics of Seagrass: Seagrasses have roots, stems, and leaves and produce flowers and seeds. Like terrestrial plants, seagrass also photosynthesizes and manufactures their own food and releases oxygen. They evolved around 100 million years ago, and there are approximately 72 different seagrass species that belong to four major groups. Distribution of Seagrass: They are found on all continents except Antarctica. The tropical waters of the Indo-Pacific hold the highest diversity of seagrasses in the world. India too has vast seagrass meadows, home to 16 species of seagrass with major concentrations in the Gulf of Mannar, Palk Bay, Andaman and Nicobar Islands, Lakshadweep Islands and the Gulf of Kutch. Advantages of Seagrass: They are better than trees for capturing carbon and providing food for millions of people. Beyond supporting marine life, seagrass also acts as a natural barrier, protecting coastal communities from storms and erosion. These underwater plants can store carbon up to 35 times faster than tropical rainforests, locking it away for thousands of years. Threats: Pollution from cities, industries, and agriculture continues to degrade these meadows, while coastal development and tourism put additional pressure on fragile habitats of seagrass. Hence option b is the correct answer. News: https://www.downtoearth.org.in/wildlife-biodiversity/seagrass-conservation-key-to-global-biodiversity-and-climate-targets-studies-show`

Answer 31

It lowers interest rates and adds liquidity to the market. Explanation : The Reserve Bank of India (RBI) recently announced its plan to infuse Rs 1.9 lakh crore into the banking system through open market purchases of government securities and USD/INR swaps About Open Market Operations (OMO): OMOs refer to a central bank selling or purchasing securities in the open market. It is a monetary policy tool to rein in inflation and money supply in the system. The Reserve Bank of India (RBI) uses OMOs in order to adjust the rupee liquidity conditions in the market on a durable basis. When the RBI feels that there is excess liquidity in the market, it resorts to the sale of government securities, thereby sucking out the rupee liquidity. Selling securities removes money from the system, raises interest rates, makes loans more expensive, and decreases economic activity. However, when liquidity is sucked out, it can lead to a spike in bond yields as the RBI will release more government securities into the market, and bond buyers demand more interest rate on these securities. Similarly, when the liquidity conditions are tight, the central bank buys securities from the market, thereby releasing liquidity into the market. Buying securities adds money to the system, lowers interest rates, makes loans easier to obtain, and increases economic activity. Hence option b is the correct answer.

1 only Explanation : ISRO recently successfully conducted the hot test on a semi-cryogenic engine (SE2000), coming closer to finalising the crucial cryogenic stage. About Semi-Cryogenic Engine: A semi-cryogenic engine (SCE) is a liquid rocket engine that uses liquid oxygen (LOX) as an oxidizer and refined kerosene as fuel. The Indian Space Research Organisation (ISRO) is developing a semi-cryogenic engine with a thrust of 2000 kN to power the booster stages of future heavy-lift launch vehicles. This engine utilizes a combination of liquid oxygen (LOX) and refined kerosene (RP-1) as propellants. The semi-cryogenic engine offers several advantages over traditional cryogenic engines, including: Higher Density Impulse: The LOX-kerosene combination provides a higher density impulse compared to LOX-liquid hydrogen, resulting in improved performance. Cost-Effectiveness: Kerosene is more cost-effective and easier to handle than liquid hydrogen, reducing overall mission costs. Operational Efficiency: Kerosene can be stored at ambient temperatures, simplifying storage and handling requirements. The development of this engine is expected to enhance the payload capacity of ISRO's existing launch vehicles, such as the LVM3, and is also planned for use in future launch vehicles like the Next Generation Launch Vehicle (NGLV). Difference between Semi-Cryogenic Engine and Cryogenic Engine: Unlike a cryogenic engine, a semi-cryogenic engine uses refined kerosene instead of liquid hydrogen. The liquid oxygen is used as an oxidiser. The advantage of using a semi-cryogenic engine is that it requires refined kerosene, which is lighter than liquid fuel and can be stored at a normal temperature. Hence only statement 1 is correct.

Only two Explanation : Assam's opposition recently raised concerns over the plight of ‘D’ (Doubtful) voters in Assam, demanding the closure of the state’s only detention centre, now termed a transit camp, and the tabling of the National Register of Citizens (NRC) report in the Assembly. About D-Voter: D-voters or doubtful voters, are a category of voters in Assam who couldn't give evidence to prove their Indian nationality and whose cases are pending with the Foreigners Tribunals or who have been declared foreigners by the Tribunal. The D-voter category was introduced by the Election Commission of India in 1997. Because their Indian citizenship has not been verified, doubtful voters are not allowed to vote in elections. They are also not permitted to run for office in the nation's elections. However, ‘doubtful voter’ or ‘doubtful citizenship’ have not been defined in the Citizenship Act, 1955, or the Citizenship Rules of 2003. The Citizenship Rules, 2003, was framed under the provisions of the Citizenship (Amendment) Act, 2003. The rules framed in 2003 list out the steps to be followed for the preparation of the National Population Register (NPR) and the National Register of Indian Citizens (NRIC). It has only been stated that the Local Registrar will include the details of individuals whose citizenship is in doubt with an "appropriate remark in the population register for further enquiry" under subsection 4 of section 4, which deals with the production of the National Register of Indian Citizens (NRIC). A family or individual is notified in a specific pro forma as soon as the verification process concludes, whether they have been classified as a dubious citizen (D-Category). Before deciding whether or not to add their name to the register, they are also given the opportunity to be heard by the Taluk or Sub-district Registrar of Citizenship. The Registrar has ninety days to complete and justify his findings. The marking as a doubtful voter is a temporary measure and cannot be prolonged. Within a specific timeframe, a decision needs to be made. According to the documentation provided, if it is determined that the individual is a foreign national or an illegal immigrant, they may be deported or placed in a detention centre. D- Voters can also apply to have their names added to the NRC. They will be included only after they get clearance from the Foreigners Tribunals and their names are removed from electoral rolls under the ‘D’ category. Hence option b is the correct answer.

Answer 46

Only two Explanation : A groundbreaking study has revealed that the Antarctic Circumpolar Current (ACC)—the world’s most powerful ocean current—is slowing down due to melting ice sheets. About Antarctic Circumpolar Current The Antarctic Circumpolar Current (ACC) is the strongest ocean current globally, flowing clockwise (from west to east) around Antarctica and connecting the Atlantic, Pacific, and Indian Oceans. As the only ocean current connecting the Atlantic, Pacific, and Indian Oceans, the ACC is five times stronger than the Gulf Stream and over 100 times more powerful than the Amazon River. The Antarctic Circumpolar Current separates the Southern Ocean from the Atlantic, Pacific, and Indian oceans at 60° S latitude, which roughly coincides with the current’s southern boundary. It plays a critical role in regulating Earth’s climate by distributing heat, water, and nutrients worldwide. Beyond climate regulation, the ACC acts as a natural barrier, preventing non-native marine species from reaching Antarctica. However, the rapid melting of Antarctic ice due to rising global temperatures is introducing large volumes of freshwater into the ocean, which can disrupt the ACC's flow. Potential Impacts of ACC Slowdown Climate Regulation: A slowdown of the ACC could lead to more extreme climate events and alter weather patterns globally. Marine Ecosystems: Changes in the ACC can disrupt nutrient distribution, affecting marine biodiversity and fisheries. Carbon Sequestration: The ocean's ability to absorb carbon dioxide may decrease, potentially accelerating global warming. Hence option b is the correct answer.

Answer 47

Unpublished Price Sensitive Information Explanation : Nestle India recently said it received a warning from the country’s markets regulator for a breach of insider trading regulations “by a designated person of the company”. About Insider Trading: Insider trading, also known as insider dealing, is the malpractice of selling or buying a company's securities by the insiders of a company. Who is an insider? The Securities and Exchange Board of India (SEBI) defines an ‘insider’ as someone who has access to price-sensitive information about a particular company's shares or securities. An insider can be anyone who has been associated with the company in some way during the six months preceding the insider trade. That person could be an employee, a director, relative, banker or a legal counsel to the company, or even an official of the stock exchanges, trustees or employees of an asset management company (AMC) that worked with the company. Insiders, who have access to confidential and exclusive information about the issuer of a particular security or stock, benefit from buying or selling undisclosed securities before they fluctuate in price. What is Unpublished Price Sensitive Information (UPSI)? UPSI refers to a piece of exclusive information related to a firm’s stock prices, quarterly results, acquisition deals, mergers, or any kind of sensitive activities that have not been shared with the public at large. When insiders are able to access the UPSI, they illegally conduct trade dealings for personal gains. Insider trading is one of the most serious malpractices that exists in the market. In India, insider trades are regulated by the SEBI under the Insider Trading Regulations, 2015. To prevent such acts of insider trading and to promote fair trading in the market for the interest of common investors, SEBI has prohibited the firms from purchasing their own shares from the secondary market. SEBI can impose fines and prohibit individuals or entities from trading in the capital market if found in violation of rules. For example, a company director informs his friend about a yet-to-be-declared deal, and the latter disseminates that information to his colleagues, who then buy that company’s stocks. Then, the manager, his friend, and his colleagues are liable to be booked by SEBI for violation of PTI (Prohibition of Insider Trading) Regulations. Hence option b is the correct answer.

An investment scam that pays early investors with money taken from later investors Explanation : The Enforcement Directorate seized a business jet at Hyderabad airport in a ₹850 crore Ponzi scam probe against a Hyderabad-based company and its promoters. About Ponzi Scheme: A Ponzi scheme is an investment scam that pays early investors with money taken from later investors to create an illusion of big profits. A Ponzi scheme promises a high rate of return with little risk to the investor. Origin: The Ponzi scheme gets its name from a swindler named Charles Ponzi, who in 1920 became a millionaire by promoting a nonexistent investing opportunity. Working: It relies on word-of-mouth, as new investors hear about the big returns earned by early investors. Inevitably, the scheme collapses when the flow of new money slows, making it impossible to keep up the payments of alleged profits. A Ponzi scheme is similar to a pyramid scheme in that use new investors' funds to pay earlier backers. A pyramid scheme usually relies on rewarding early participants to recruit more participants but collapses when the supply of potential participants dwindles. Notable Ponzi Scams in India: Saradha Scam (2013): A multi-crore chit fund scam in West Bengal that defrauded lakhs of investors. Rose Valley Scam: A larger scam than Saradha, involving over Rs 15,000 crore. SpeakAsia (2011): A pyramid-like scheme posing as an online survey business. PACL (Pearl Agro Corporation Limited) Scam: Collected Rs 49,100 crore from investors under the guise of land investments. Safeguards against Ponzi Schemes in India: Ponzi schemes are banned under the Prize Chit and Money Circulation (Banning) Act, 1978, a Central Act enforced by State governments. Additionally, the Unregulated Deposit Schemes Act, 2019 explicitly bans Ponzi schemes, further strengthening legal action against such frauds. These are also dealt with by the Enforcement Directorate under the Prevention of Money Laundering Act, 2002. Hence option d is the correct answer.

2 only Explanation : In a setback to global climate justice efforts, the United States has withdrawn from the loss and damage fund aimed at compensating developing countries for the damages caused by climate change. About Loss and Damage Fund (LDF): Loss and damage refers to the negative consequences that arise from the unavoidable risks of climate change, like rising sea levels, prolonged heatwaves, desertification, the acidification of the sea and extreme events, such as bushfires, species extinction and crop failures. Establishment: The Fund was established at the 2022 UNFCCC Conference (COP27) in Egypt, to provide financial support to regions suffering both economic and non-economic losses caused by climate change. Developing countries, particularly small island states that face the greatest threats from climate impacts, had been demanding financial assistance in case of climate-related disasters, arguing that they were having to suffer due to a problem created by rich and developed countries. About $750 million has so far been promised for the fund, of which the US has contributed $17.5 million. The US, in fact, is one of the very few countries to have already transferred its committed amount to the Fund. The LDF is overseen by a Governing Board that determines how the fund’s resources are disbursed, with the World Bank serving as the interim trustee tasked with hosting the fund for four years. Paris Agreement: The Paris Agreement is an international accord that was adopted by nearly every country in 2015 to address climate change and its adverse effects. Its primary goal is to substantially reduce greenhouse gas (GHG) emissions in a bid to limit global warming in this century to “well below” 2 degrees Celsius above pre-industrial levels while pursuing the means to curb warming to 1.5 degrees. The agreement mentions the safer limit of 1.5 degrees based on a fact-finding report which found that breaching the threshold could lead to “some regions and vulnerable ecosystems” facing high risks, over an extended, decades-long period. The treaty also requires all Parties (countries which have joined the agreement) to state every five years what they are doing to tackle climate change — what is known as their nationally determined contribution (NDC). Hence only statement 2 is correct.

Bivalve mollusk Explanation : A new deep-sea predator has been discovered in the Atacama Trench, though incredibly small in size, possesses lethal hunting abilities that make it a formidable force in its underwater ecosystem. About D. camanchaca: It is a newly discovered amphipod, a shrimp-like marine creature, marking the first known predatory amphipod in the hadal zone—depths exceeding 6,000 meters below the ocean surface. Unlike most amphipods that feed on detritus, it is an active predator, using specialized appendages to catch and consume other organisms. This behaviour is rare among deep-sea creatures, which typically rely on scavenging due to the scarcity of food. D. camanchaca has adapted to freezing temperatures and immense pressure, which exceeds 1,000 times the atmospheric pressure at sea level. The genus name Dulcibella is inspired by Dulcinea, a character from Don Quixote. However, since this name was already assigned to another species, researchers chose camanchaca, meaning "darkness" in some South American languages—a fitting name for a creature that thrives in total darkness. Hence option d is the correct answer. News: https://timesofindia.indiatimes.com/etimes/trending/a-new-deep-sea-predator-has-been-discovered-and-its-tiny-but-deadly/articleshow/118802882.cms

Virus Explanation : A new global survey shows that 56.6% of Indian participants aged 50 and above know little to nothing about shingles, although more than 90% of adults above 50 years have this virus in their body, and are vulnerable to the disease. About Shingles Disease: Shingles (herpes zoster) is a viral infection that causes an outbreak of a painful rash or blisters on the skin. The rash most often appears as a band of rashes or blisters in one area of your body. Shingles can occur anywhere on your body. The risk of shingles goes up as you get older and it is most common in people over age 50. What Causes Shingles? It's caused by the varicella-zoster virus, which is the same virus that causes chickenpox. When you have chickenpox as a child, your body fights off the varicella-zoster virus and the physical signs of chickenpox fade away, but the virus always remains in your body. In adulthood, sometimes the virus becomes active again. This time, the varicella-zoster virus makes its second appearance in the form of shingles. Is Shingles Contagious? Shingles is not contagious, but the virus can be spread to someone who has never had chickenpox. This will cause chickenpox, not shingles. Symptoms: The symptoms of shingles can include pain, itching, tingling, and numbness, as well as fever, headache, chills, and fatigue. Shingles isn't life-threatening. But it can be very painful. The most common complication is postherpetic neuralgia. This is a painful condition that causes shingles pain for a long time after your blisters have cleared. Prevention: There is a vaccine called Shingrix available, which helps in preventing shingles and its complications. Treatment: There is no cure for shingles. Antiviral medications can reduce the severity and duration of shingles, especially if started early. Hence option c is the correct answer. News: https://www.thehindu.com/sci-tech/health/global-survey-shows-most-people-over-50-in-india-unaware-of-shingles-disease-despite-being-at-risk/article69280100.ece

Answer 71

Only two Explanation : The Supreme Court recently quashed a preventive detention order by Nagaland's home department, emphasizing that detaining authorities must independently apply their minds. About Preventive Detention: Preventive detention refers to the detention of an individual without a trial or conviction by a court. The primary objective of preventive detention is not to punish an individual for a past offence but to prevent them from committing an offence in the future. Preventive detention laws are enacted by governments to ensure public safety and maintain social order. Constitutional Provisions and Safeguards: Article 22 of the Constitution of India grants protection to individuals who are arrested or detained. It has two parts—the first part deals with cases of ordinary law, which includes situations where an individual is detained as part of a criminal investigation. The second part deals with cases of preventive detention law, which pertains to the detention of individuals without a trial or conviction. Article 22(4) states that no law providing for preventive detention shall authorise the detention of a person for a longer period than three months unless an Advisory Board reports sufficient cause for extended detention. The detainee is entitled to know the grounds of his detention. The state, however, may refuse to divulge the grounds of detention if it is in the public interest to do so. The detaining authorities must give the detainee earliest opportunities for making representation against the detention. Who can make laws under Preventive Detention? Parliament has the exclusive power to enact a law for preventive detention for reasons connected with defence, foreign affairs, or security of India. Both Parliament and State Legislature have powers to enact a law for preventive detention for reasons related to the maintenance of public order or the maintenance of supplies or services essential to the community. Laws that provide for Preventive Detention: In India, various laws provide for preventive detention, including the National Security Act (NSA) of 1980, the Unlawful Activities (Prevention) Act (UAPA) of 1967, and state-specific laws like the Maintenance of Internal Security Act (MISA) and the Public Safety Acts (PSA) in certain states. Under these laws, authorities can detain an individual for a specific period, typically up to 12 months, without presenting formal charges or conducting a trial. The detention order is issued by a designated authority or government official and is subject to periodic review by an advisory board. Hence option b is the correct answer.

About Trade-to-Trade (T2T) Segment: T2T stocks, or Trade-to-Trade stock means stocks that must be delivered in order to be traded (T+2 settlement). This implies that such equities cannot be traded intraday or, in the case of Buy Today Sell Tomorrow, on a daily basis. This means if you acquire T2T stocks today, you won’t be able to sell them until the settlement takes place. Your order will be refused if you try to sell these shares the same day or before they are in the Demat account. Stocks are put under the T2T segment by the exchanges based on criteria such as their price-earnings ratio, price variations, market capitalisation, etc. Stocks that are very volatile or have irregular price movements are monitored by exchanges in cooperation with the market regulator, SEBI. They put stocks in the T2T section to shield regular investors from being caught up in the volatility and to limit unwarranted speculation on such equities. On a biweekly basis, exchanges relocate stocks to the T2T section, and they are shifted in and out of the segment depending on quarterly evaluations. Also evaluated for transfer to the T2T sector are stocks that are not available for trade in the Futures & Options section. How to identify stocks in the T2T segment? Stocks in the T2T segment can be identified by changes in their scrip names: National Stock Exchange (NSE): The addition of the word "BE" to the scrip name. For example, "ADANIPOWER" becomes "ADANIPOWER BE" in the T2T segment and reverts to "ADANIPOWER" after normal trading is allowed. Bombay Stock Exchange (BSE): The addition of the letter "T" to the scrip name. For instance, "ADANIPOWER" changes to "ADANIPOWER T" when moved to the T2T segment. Hence both statements are correct.

Only three Explanation : China recently deployed a powerful Large Phased Array Radar (LPAR) in Yunnan province, near the China-Myanmar border. About Large Phased Array Radar (LPAR): It was established by China in Yunnan province, near the China-Myanmar border. It boasts a surveillance range exceeding 5,000 kilometers, allowing China to monitor extensive areas of the Indian Ocean and deep into Indian territory. It possesses the capability to detect and track ballistic missile launches in real time. Unlike traditional radars, which rely on mechanical rotation, LPARs use electronically controlled antennas to scan vast areas almost instantly. This allows them to track multiple targets, including ballistic missiles, with high precision. Such radars play a critical role in early warning systems and air defence networks. How does China's LPAR compare to the world? Besides China, only the US and Russia have the LPAR system. The capabilities of China's LPAR are being compared to the US PAVE PAWS (Precision Acquisition Vehicle Entry Phased Array Warning System), a Cold War-era radar designed to detect long-range missile launches. The American system has a detection range of approximately 5,600 km and can track multiple projectiles, including submarine-launched ballistic missiles. Concerns for India: The Yunnan-based LPAR can monitor deep into Indian territory and track missile tests conducted from Dr APJ Abdul Kalam Island off India's eastern coast. This site is crucial for testing strategic weapons like the Agni-V intercontinental ballistic missile and the K-4 submarine-launched missile. By capturing vital data on missile trajectories, speeds, and distances, China gains a strategic advantage, enabling it to analyse and develop countermeasures. Hence option c is the correct answer.

Answer 86

The cooling of surface-ocean waters along the tropical west coast of South America. Explanation : Climate change is intensifying, and the cooling effects of La Niña may weaken in a warmer future, climate scientists warn, citing current heat trends across much of the country. About La Nina: La Niña is a climate pattern that describes the cooling of surface-ocean waters along the tropical west coast of South America. It is considered to be the counterpart to El Niño, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean. Together, La Niña and El Niño are the "cold" (La Niña) and "warm" (El Niño) phases of the El Nino-Southern Oscillation (ENSO). ENSO is series of linked weather- and ocean-related phenomena. La Niña events are indicated by sea-surface temperature decreases of more than 0.5 degrees Celsius (0.9 degrees Fahrenheit) for at least five successive three-month seasons. Causes: La Niña is caused by a build-up of cooler-than-normal waters in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn. Unusually strong, eastward-moving trade winds and ocean currents bring this cold water to the surface, a process known as upwelling. Upwelling can cause a drastic drop in sea-surface temperature. Effects: Impact on Air Pressure and Rainfall: La Niña lowers air pressure over the western Pacific, leading to increased rainfall. South Asia experiences stronger summer monsoons, benefiting agriculture in India and Bangladesh. Risk of Flooding in Australia: While La Niña supports agriculture in South Asia, strong events can cause severe flooding in northern Australia due to excessive rainfall and low-pressure systems. Global Rainfall Patterns: La Niña brings more rain to southeastern Africa and northern Brazil. In contrast, it increases air pressure over the central and eastern Pacific, causing dry conditions. Drier Conditions in Some Regions: Regions like the west coast of tropical South America, the Gulf Coast of the US, and the pampas of South America experience reduced rainfall and dry spells during La Niña. Boost to the Fishing Industry: Upwelling caused by La Niña brings cold, nutrient-rich waters to the surface, supporting plankton growth. This benefits fish populations and predators like sea bass. Duration and Seasonal Peak: La Niña events usually last between one and three years, whereas El Niño typically lasts less than a year. Both tend to peak during the Northern Hemisphere winter. Hence option a is the correct answer.

Mitochondria Explanation : A 22-year-old young prince of Luxembourg, Prince Frederik, recently died from a rare genetic disease called POLG. About POLG Disease: It is a genetic mitochondrial disorder that prevents the body’s cells from producing adequate energy, which in turn can cause multiple organ dysfunctions and failures. The disease affects multiple organs of the body, primarily the brain, nerves, muscles, and liver. It could also affect a person’s vision due to the involvement of affected brain structures. People with POLG “likely end up bedridden and unable to function in so many of those activities of daily living. Causes: The condition affects mitochondria, the “powerhouse” of the cell, which converts food into ATP (Adenosine triphosphate), the primary source of energy in living cells of a body. Mitochondria contain their own DNA, which requires a specific enzyme to replicate, found in the host cell’s POLG and POLG2 genes. Mutations in these genes therefore impact the ability for mitochondria to replicate. Symptoms: A person can see symptoms, from mild to severe, starting from early childhood to adulthood. The most frequent symptoms include muscle weakness, ophthalmoplegia (weakness or paralysis of the eye), epilepsy, and liver failure. POLG also affects neurological function and impacts a person’s ability to balance, talk, and walk, and it causes seizures and more. Treatment: There is currently no cure for POLG.

Northeastern India Explanation : An armoured vehicle of the central security forces came under heavy attacks by protesters from the Kuki tribes in Manipur on the first day of the Centre's order to ensure free movement of people in the crisis-hit state. About Kuki Tribe The Kukis are an ethnic group including multiple tribes originally inhabiting the Northeastern States of India, including Manipur, Mizoram and Assam; parts of Burma (now Myanmar), and Sylhet district and Chittagong hill tracts of Bangladesh. The Chin people of Myanmar and the Mizo people of Mizoram are kindred tribes of the Kukis and are collectively known as the Zo people. Notably, Kuki is not a term coined by the ethnic group itself, the tribes associated with it came to be generically called Kuki under the colonial rule, and were further divided by the British into ‘old Kukis’ and ‘new Kukis’. The Kukis have a rich cultural heritage, with institutions like Sawm and Lawm playing significant roles in their society. Sawm is a community center for boys where they learn under the guidance of elders, while Lawm is a youth club that fosters social activities and practical skills The Kukis traditionally engaged in shifting or Jhum cultivation in the forested hills, which allowed them to expand their settlements through the wooded areas over generations. Their expansionist land ownership patterns due to Jhum cultivation put them at odds with the Nagas, who practised territorial agriculture, and the Meiteis, who lived in the cultivated valley areas. Kuki Rebellion of 1917-19 The first resistance to British hegemony by the Kuki people was the Kuki Rebellion of 1917-19, after which their territory was subjugated by the British and divided between the administrations of British India and British Burma. Up until their defeat in 1919, the Kukis had been an independent people ruled by their chieftains. Hence option b is the correct answer.

an exotic phase of ice that forms under extreme conditions Explanation : Scientists have confirmed the existence of a fourth form of water, Plastic Ice VII, an exotic phase of ice that forms under extreme conditions. About Plastic Ice: Under normal conditions, water exists in three phases: solid (ice), liquid (water), and gas (vapour or steam). Unlike ordinary ice, Plastic Ice VII allows water molecules to rotate freely within a rigid crystalline structure. This phase was first predicted in 2008, but scientists have now provided solid evidence of its existence using advanced neutron-scattering experiments at the Institut Laue-Langevin in France. The unique structure of Plastic Ice VII forms at pressures exceeding three gigapascals (GPa), about 30,000 times atmospheric pressure on Earth, and temperatures above 450 Kelvin (177Â°C). How Was It Discovered? Researchers used quasi-elastic neutron scattering (QENS) and diamond-anvil cells to study tiny high-pressure samples. These techniques allowed them to analyze molecular motion at the atomic scale. Their findings confirm that while Plastic Ice VII retains a crystalline structure, its molecules rotate in specific, preferred directions. Significance of Plastic Ice Discovery This discovery has profound implications for planetary science. Ice VII, an earlier known phase, exists deep inside the icy moons of Jupiter and Saturn, such as Callisto, Ganymede, and Titan. Now, the confirmation of Plastic Ice VII suggests that water in extreme environments behaves in even more complex ways than previously thought. Understanding this exotic ice could help scientists explore whether extreme planetary conditions could support life and how water influences the structure of celestial bodies. Scientists believe this discovery could lead to new insights in materials science, planetary exploration, and even the development of futuristic technologies that use extreme pressure conditions. Hence option a is the correct answer. News: https://www.newsx.com/space-science/what-is-plastic-ice-the-fourth-form-of-water-discovered-by-scientists/

Answer 104

Quantum mechanics Explanation : In an exciting scientific breakthrough, researchers have successfully turned light into a "supersolid" for the first time ever. About Supersolid: Supersolids are a strange state of matter defined by quantum mechanics where particles condense into an orderly, crystalline solid but also move like a liquid that has no viscosity. Usually, solids don't move on their own, but supersolids change direction and density depending on particle interactions while maintaining an organized lattice structure. Why Are Supersolids So Cold? Supersolids require extremely low temperatures to form — usually very close to absolute zero (minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius). Most of the particles have to occupy the lowest energy state available, and heat makes particles jump up and down like excitable toddlers in a ball pit. If a material is cold enough, the temperature no longer obscures how the particles interact with each other. Instead, the tiny effects of quantum mechanics become the defining factors in how the material behaves. Significance of the Discovery: Supersolids have traditionally been observed in Bose-Einstein condensates (BECs) of ultracold atoms near absolute zero. However, this new development expands the scope by coupling light and matter, enabling researchers to study condensed-matter physics under extreme quantum conditions. The discovery has profound implications for quantum computing, where supersolid-based systems could enhance qubit stability. It also opens pathways for advancements in optical circuits, photonic devices, and fundamental physics research. Hence option a is the correct answer.

Armenia - Azerbaijan Explanation : Armenia and Azerbaijan have agreed to a peace agreement set to end nearly four decades of conflict between over disputed Nagorno-Karabakh region. About Nagorno-Karabakh: Nagorno-Karabakh, referred to as Artsakh by Armenians, is a landlocked, mountainous region in the South Caucasus. The general region includes the northeastern flank of the Karabakh Range of the Lesser Caucasus and extends from the crest line of the range to the margin of the Kura River lowland at its foot. Nagorno-Karabakh’s environments vary from steppe on the Kura lowland through dense forest of oak, hornbeam, and beech on the lower mountain slopes to birchwood and alpine meadows higher up. Following the Russian Empire's collapse in 1917, both Armenia and Azerbaijan asserted claims over this area, leading to enduring tensions. Internationally recognized as part of Azerbaijan, until recently much of it was governed by the unrecognised Nagorno-Karabakh Republic, also known as the Republic of Artsakh. Historically, the region's population was predominantly ethnic Armenian, and it operated a self-established government closely aligned with Armenia, though lacking official recognition from Armenia or other United Nations member states. Nagorno-Karabakh Conflict Timeline: The conflict has roots dating back well over a century into competition between Christian Armenian and Muslim Turkic and Persian influences. 1920s: After World War I and the Bolshevik revolution, Soviet rulers created the Nagorno-Karabakh Autonomous Region within Azerbaijan, with an ethnic Armenian majority. 1991: As the Soviet Union collapsed, Karabakh declared independence, and tensions between Armenians and Azerbaijanis led to full-scale war. 1992-94: The First Karabakh War resulted in up to 30,000 deaths. Armenians took control of the region and occupied surrounding Azerbaijani land, creating a buffer zone. 2017: A referendum in Karabakh changed the government to a fully presidential system and renamed the region from Nagorno-Karabakh Republic to Republic of Artsakh. 2020: The Second Karabakh War saw Azerbaijan reclaiming territory around Karabakh, with 3,000 Azerbaijani and 4,000 Armenian soldiers killed in six weeks of fighting. 2022: Clashes broke out between Armenian and Azerbaijani forces, with 100 Armenian and 70 Azerbaijani soldiers killed. 2024: Nagorno-Karabakh was officially dissolved.

About Melioidosis: It is a bacterial infectious disease caused by Burkholderia pseudomallei. B. pseudomallei lives in surface water (streams, rivers, lakes) and soil, mostly in tropical or subtropical areas. It is endemic in Southeast Asia, northern Australia, much of the Indian subcontinent, southern China, Hong Kong, and Taiwan. It is also sometimes called Whitmore’s disease. It has a high case fatality rate (CFR) ranging from 16% to 50% in known endemic regions. Transmission: Both humans and animals can get melioidosis, but people can’t get it from animals. It's spread to people and animals through direct contact with soil, air, or water contaminated by the bacteria. Cases may increase after hurricanes, heavy rain, and other severe weather events because the bacteria rise to the surface of the soil. In areas where it’s more commonly found, melioidosis usually affects adults 40 to 60 years old with certain underlying conditions. Children under 15 rarely get melioidosis. Symptoms: Melioidosis may present with localised infection (such as cutaneous abscess), pneumonia, meningoencephalitis, sepsis, or chronic suppurative infection. Depending on the site of infection, common symptoms include fever, headache, localised pain or swelling, ulceration, chest pain, cough, shortness of breath, haemoptysis, and swelling of regional lymph nodes. Treatment: It can be treated with antibiotics. Long-term treatment may be necessary for some chronic infection cases. Hence option c is the correct answer.

Both 1 and 2 Explanation : The clinical trial results of India’s first CAR T-cell therapy, published in The Lancet, show that it worked for nearly 73 percent of patients. About CAR T-cell Therapy CAR T-cell therapy, or chimeric antigen receptor T-cell therapy, trains the body’s own immune cells to identify and destroy cancer cells. This treatment is designed for specific types of blood cancer and is given to patients whose cancer has either relapsed or not responded to first-line treatment. How does the therapy work? For any CAR T-cell therapy, a patient’s immune T-cells are collected by filtering their blood. These cells are then engineered in a lab to add receptors that can bind with cancer cells. These cells are then multiplied and infused in the patient. Usually, the cancer cells are adept at evading the unmodified T cells. The treatment developed in India is meant for patients with two types of blood cancers that affect the B cells — acute lymphoblastic leukemia and large B cell lymphomas. Side Effects of CAR T Therapy A serious immune overreaction causing hyperinflammation and organ damage, seen in 12% of participants, resulting in at least one death. Low red blood cell count, reported in 61% of participants, causing fatigue and weakness. Thrombocytopenia: Low platelet count, increasing the risk of bleeding, reported in 65% of patients.

Volcanic eruptions that released large amounts of carbon dioxide Explanation : The End-Permian Mass Extinction that killed 80% of life on Earth 250 million years ago may not have been quite so disastrous for plants, new fossils hint. About End-Permian Mass Extinction (EPME): The End-Permian Mass Extinction (EPME), also known as the Permian-Triassic Extinction Event or "The Great Dying," was the most severe extinction event in Earth's history. It occurred approximately 252 million years ago and marked the transition from the Permian to the Triassic Period. The Triassic Period is the first period of the Mesozoic Era, lasting from 252 million to 201 million years ago. Cause: At that time, the supercontinent Pangea was in the process of breaking up, but all land on Earth was still largely clustered together, with the newly formed continents separated by shallow seas. An enormous eruption from a volcanic system called the Siberian Traps seems to have pushed carbon dioxide levels to extremes. The eruption covered around 2 million square kilometers with lava and was one of the largest volcanic events in Earth’s history. The eruptions may have caused large amounts of carbon dioxide to be released into the atmosphere and caused a large-scale global warming effect of more than 10°C on land and around 8°C on the ocean surface in a short period of time. The eruptions may have also caused acid aerosols and dust clouds to be released into the atmosphere, which blocked out the sun and prevented photosynthesis from occurring, effectively causing many food chains to collapse. This caused global warming and ocean acidification, leading to a massive collapse of the ocean ecosystem. Impacts: EPME was characterized by the elimination of about 90 percent of the species on Earth, which included more than 95 percent of the marine species and 70 percent of the terrestrial species. In addition, more than half of all taxonomic families present at the time disappeared. It ranks first in severity among the five major extinction episodes that span geologic time. Hence option c is the correct answer. News: https://www.livescience.com/planet-earth/fossils/refuge-from-the-worst-mass-extinction-in-earths-history-discovered-fossilized-in-china

2 only Explanation : Despite being a rare disease globally, Subacute Sclerosing Panencephalitis (SSPE) remains a serious health concern in Lucknow and Uttar Pradesh due to low measles vaccination coverage. About Subacute Sclerosing Panencephalitis (SSPE): It is a progressive and usually fatal brain disorder related to measles (rubeola) infection. SSPE tends to occur several years after a person has measles, even though the person seems to have fully recovered from the illness. Cause: Normally, the measles virus does not cause brain damage. However, an abnormal immune response to measles or, possibly, certain variant forms of the virus may cause severe illness and death. This response leads to brain inflammation (swelling and irritation) that may last for years. SSPE has been reported in all parts of the world, but in western countries it is a rare disease. Males are more often affected than females. The disease generally occurs in children and adolescents. Symptoms: The first symptoms of SSPE may be poor performance in schoolwork, forgetfulness, temper outbursts, distractibility, sleeplessness, and hallucinations. Sudden muscular jerks of the arms, head, or body may occur. Eventually, seizures may occur, together with abnormal uncontrollable muscle movements. Intellect and speech continue to deteriorate. Later, the muscles become increasingly rigid, and swallowing may become difficult. The swallowing difficulty sometimes causes people to choke on their saliva, resulting in pneumonia. People may become blind. In the final phases, the body temperature may rise, and the blood pressure and pulse become abnormal. Treatment: High mortality rates are associated with SSPE, and there is no cure for SSPE. Treatment is generally aimed at regulating symptoms. Certain antiviral medicines and medicines that boost the immune system may be tried to slow the progression of the disease. Hence only statement 2 is correct.

Both 1 and 2 Explanation : 10-year-old Alberto Davila Aragon from Bristol, UK set a new world record by recalling 280 decimal places of Pi in one minute on Pi Day. About Pi Day: Pi Day, or International Day of Mathematics, celebrated on March 14 every year, honours the mathematical constant Pi, recognising its significance in mathematics. Pi Day is celebrated by lovers of mathematics every year through Pi recital competitions and Pi Day workouts to stimulate interest in learning and practising mathematics. The theme for Pi Day 2025 is ‘Mathematics, Art, and Creativity’. Why March 14? The approximate value of Pi is 3.14. The date, when written in the format of month/day (3/14), matches the first three digits of the mathematical constant. History of Pi Day: The first Pi Day was celebrated in 1988 by physicist Larry Shaw at the San Francisco Exploratorium. In 2009, the United States House of Representatives officially designated March 14 as Pi Day. Later, in 2019, UNESCO declared Pi Day as the "International Day of Mathematics" during its general conference. Albert Einstein, the renowned physicist behind the "General Theory of Relativity," was born on Pi Day in 1879. What is Pi (π)? Pi is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. It is an infinitely long, irrational number, and its exact value cannot be known. Pi has been calculated to over 50 trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. It is roughly equal to 3.14, or 22/7. It is represented by the Greek letter ‘π.’ Why that letter? It’s the first Greek letter in the words “periphery” and “perimeter,” and pi is the ratio of a circle’s periphery — or circumference — to its diameter. History: Pi has been known for nearly 4,000 years and was discovered by the ancient Babylonians. One of the first calculations of pi was carried out by Greek mathematician Archimedes of Syracuse (287 B.C. to 212 B.C.). The symbol π was devised by British mathematician William Jones in 1706. Applications: It is used in a wide variety of mathematical and scientific calculations, including geometry, trigonometry, calculus, and more. Hence both statements are correct.

Origin: It was first identified in 2004 by researchers at Hong Kong University, which is how it got its name. Symptoms: The symptoms of HKU1 include a runny nose, fever, coughing, wheezing, headache, and sore throat. While symptoms are usually mild, untreated cases can sometimes lead to bronchiolitis and pneumonia. Transmission: It is transmitted during direct contact with the infected person via respiratory droplets (coughing or sneezing), touching contaminated surfaces and then touching the face, mouth, or nose. Vulnerability: The disease is self-limiting and resolves on its own. But vulnerable groups like the elderly, children, pregnant women, those with immuno-compromised conditions or with co-morbidities need to be vigilant for severe manifestation of the disease. Treatment: There is no vaccine or specific treatment for human coronaviruses. Most infected individuals get better on their own. Difference between HKU1 and COVID-19: HKU1 and COVID-19 are both caused by coronaviruses, but HKU1 is less severe than Covid-19. HKU1 is one of the four endemic human coronaviruses that cause common cold, while COVID-19 is caused by SARS-CoV-2, a novel coronavirus that can cause severe respiratory illness and has caused a global pandemic.

Japan Explanation : Japan will introduce climbing fees of US$27 on Mount Fuji’s four main trails this summer to address overcrowding and enhance safety for tourists. About Mount Fuji: Mount Fuji, also called Fuji-san, is Japan's tallest mountain, with a height of 3,776 meters. It is situated close to the Pacific coast in the Yamanashi and Shizuoka prefectures in the heart of the large island of Honshu, about 100km to the southwest of the Tokyo-Yokohama metropolitan area. It is part of the Fuji Volcanic Zone, a volcanic chain that extends northward from the Mariana Islands and the Izu Islands through the Izu Peninsula to northern Honshu. It is a stratovolcano that has been dormant since its last eruption, in 1707, but is still generally classified as active by geologists. Mount Fuji is one of Japan's "Three Holy Mountains" along with Mount Tate and Mount Haku. The mountain is the major feature of Fuji-Hakone-Izu National Park (1936), and it is at the centre of a UNESCO World Heritage site designated in 2013. Mount Fuji Origin: According to tradition, the volcano was formed in 286 BCE by an earthquake. The truth is somewhat more complex. The age of Fuji is disputed, but it seems to have formed during the past 2.6 million years on a base dating from up to 65 million years ago; the first eruptions and the first peaks probably occurred sometime after 700,000 years ago. The earliest precursors to Mount Fuji were Komitake (which forms the mountain’s north slope) and Ashitaka-yama (which sits southeast of the mountain). The present-day mountain is a composite of three successive volcanoes: at the bottom is Komitake, which was surmounted by Ko Fuji (“Old Fuji”) about 100,000 years ago and, finally, by the most recent, Shin Fuji (“New Fuji”). Hence option d is the correct answer. News: https://www.ndtv.com/world-news/mount-fuji-hikers-will-now-be-charged-over-rs-2-000-on-all-trails-7941883

They allow specific individuals to hear a sound privately, even in crowded environments Explanation : Audible Enclaves: A New Sound Technology What are Audible Enclaves? Audible Enclaves are small pockets of sound that are not disturbed by surrounding noise. They allow specific individuals to hear a sound privately, even in crowded environments. The technology is based on sound wave manipulation, ensuring that only intended listeners can hear the transmitted sound. How Does Sound Work? Sound consists of waves moving through a medium, causing particles to vibrate back and forth. The speed of vibration determines the frequency: Higher frequency = Higher pitch sound. When sound waves are emitted from a source, they diverge in a process called diffraction. Higher frequency sounds diverge more than lower frequencies. How Are Audible Enclaves Created? Traditional parametric array loudspeakers create focused sound beams using high-frequency waves modulated with an audio signal. Audible enclaves take this a step further using two high-frequency waves of different frequencies: These waves are inaudible on their own. When they intersect, non-linear interactions generate a sound wave audible only at that specific location. This method, reported in the Proceedings of the National Academy of Sciences ensures that only individuals within a defined zone can hear the sound. Hence option b is the correct answer.

All four Explanation : India is progressing towards eliminating Neglected Tropical Diseases (NTDs) through political support, community involvement, and regional cooperation. About Neglected Tropical Diseases (NTDs): NTDs are a diverse group of conditions caused by a variety of pathogens (including viruses, bacteria, parasites, fungi, and toxins) and associated with devastating health, social, and economic consequences. NTDs are mainly prevalent among impoverished communities in tropical areas, although some have a much larger geographical distribution. They are widespread where people in vulnerable situations live, where water safety, sanitation, and access to health care are inadequate or suboptimal. These diseases are called “neglected” because they have historically ranked very low on the global health agenda, when they have appeared at all, receiving little attention and funding. NTDs include Guinea worm, Chikungunya, Dengue, Kala Azar (Visceral Leishmaniasis), and Elephantiasis (Lymphatic Filariasis), among others. India is home to about 12 NTDs. The epidemiology of NTDs is complex; some have animal and/or human reservoirs, many are vector-borne, and most are associated with intricate life cycles. Preventing or eliminating NTDs is therefore challenging. It is estimated that NTDs affect more than 1 billion people, while the number of people requiring NTD interventions (both preventive and curative) is 1.5 billion. Every year on 30th January, the Global community comes together to mark World NTDs Day and renew its commitment to eliminating its burden worldwide. Hence option d is the correct answer.

1 only Explanation : As per the recently introduced incentive scheme to promote low-value BHIM-UPI transactions, small merchants will pay no merchant discount rate (MDR) and banks will receive an incentive of 0.15% per transaction. About Merchant Discount Rate (MDR): MDR (alternatively referred to as the Transaction Discount Rate or TDR) is a fee that merchants and other businesses must pay to a payment processing company for accepting payments from customers via digital modes like credit cards, debit cards, UPI, etc. MDR compensates the bank issuing the card, the bank which installs the PoS (Point of Sale) terminal and network providers, and payment gateways for their services. The MDR sums up all the charges and taxes that electronic or digital payments entail. The MDR typically comes in the form of a percentage of the transaction amount. It is typically between 1% and 3%. The rates are dependent on the level of business transactions being processed, the types of cards (debit or credit) used by customers, and the value of the average transaction (also known as average tickets or average sales). Before accepting debit and credit cards, merchants must set up this service and agree to the rate. Merchants must consider these fees as part of managing their business costs and setting their prices. MDR charges are automatically deducted from the merchant’s account at the time of settling the transaction batch. Under the rules laid down by RBI, business owners cannot pass on the MDR charges to their customers. Hence only statement 1 is correct.

Both 1 and 2 Explanation : Serbian government has been accused of using a banned ‘sonic weapon’ to disperse protesters in Belgrade. What are Sonic Weapons? Sonic weapons (Acoustic Weapons) are devices that deliver loud, painful sounds over long distances. They can emit audible or inaudible sound waves to disrupt, disorient, or incapacitate people. Some versions act as voice amplifiers, allowing authorities to issue commands over large distances. First developed for military and crowd control purposes, they were used in Iraq (2004) by the U.S. military. How Do Sonic Weapons Work? They use hundreds of transducers (electronic devices that convert energy into sound waves). The highly concentrated and amplified sound can be directed at specific targets. Authorities control the frequency, volume, and duration of the sound. The narrow sound beam can cause extreme discomfort, pain, and disorientation to those exposed. Types of Sonic Weapons: Long-Range Acoustic Device (LRAD): Used by law enforcement and military for crowd control. Can project sound over 8,900 meters at up to 160 decibels (dB). Causes ear pain, hearing damage, nausea, and dizziness. Mosquito Device: Emits a high-pitched sound that only younger people (below 30 years) can hear. Used to deter loitering in public areas. Causes irritation and discomfort in young individuals. Infrasonic Weapon: Emits low-frequency sounds that are inaudible to humans but cause physical pain and disorientation. Still under research.

They are stronger than real GPS signals. Explanation : As many as 465 GPS interference and spoofing incidents have been reported in the border region, mostly in the Amritsar and Jammu areas, between November 2023 and February 2025, the government said recently. What is a Spoofing Attack? A “spoofing attack” is a broad category of cyberattack where fake data is disguised as originating from a trusted source to deceive systems or users. Kinds of spoofing include GPS Spoofing, IP spoofing—often used to avoid detection while performing Distributed Denial of Service (DDoS)—as well as SMS spoofing and caller ID spoofing, where messages or calls appear to be from another number or caller ID. About GPS Spoofing: GPS spoofing uses bogus radio signals to imitate legitimate Global Positioning System (GPS) signals, misdirecting GPS-receiving devices about their actual location. This can result in incorrect navigation data and potentially life-threatening situations, especially in systems that rely heavily on precise location information. How GPS Spoofing Works? GPS spoofing exploits the inherent vulnerabilities in the GPS infrastructure – the weak signal strength of GPS satellites. The GPS functions by sending signals from satellites to GPS receivers on Earth. These receivers then calculate their position based on the time it takes for these signals to arrive. However, due to the weak signal strength of the GPS satellites, these signals can be easily overwhelmed by fake signals,resulting in inaccurate location data on the receiving device. Typically, a GPS spoofer begins by acquiring a basic understanding of the victim’s GPS setup, including the types of signals it uses and how they are processed. With that information, the attacker then sends counterfeit GPS signals that mimic the real ones. These fake signals are stronger, causing the receiver to recognize them as authentic signals. As a result, the victim’s GPS receiver ends up processing these counterfeit signals, leading to erroneous location information. Hence option b is the correct answer.

About Corbett Tiger Reserve: It is located on the foothills of the Himalayas in Uttarakhand. Establishment: Corbett is the first national park of India, established in 1936. It was named Hailey National Park then. In 1957, the park was rechristened Corbett National Park in memory of the late Jim Corbett, a great naturalist and eminent conservationist. After the addition of areas to the originally declared National Park, the total area of Tiger Reserve extends to 1288.31 sq. km. The terrain is undulating with several valleys. The rivers Ramganga, Pallaen, and Sonanadi flow through the valleys. By and large, the reserve is spread over the Bhabar and lower Shivalik regions with a deep-water table. The tract is porous with boulders and sand deposits. Flora: In general, the vegetation comprises sal and mixed forests, interspersed with grass lands and riparian vegetation. The grasslands are locally known as ‘Chaur’, which are an outcome of abandoned settlements or past clearings. Evergreen Sal and its combined trees, the Sheesham, and the Kanju are found extensively on the ridges. One plant, (actually a weed), which is a major irritant to the reserve authorities and is widespread in the jungle, is the Lantana. Fauna: Tigers and elephants are the charismatic mammals, besides a large array of co-predators (leopards, small carnivores), ungulates (sambar, hog deer, spotted deer), birds, reptiles (gharials, crocodile), and fishes.

Both 1 and 2 Explanation : Rates of relative sea-level rise during the final stage of the last deglaciation, the early Holocene, are key to understanding future ice melt and sea-level change under a warming climate. About Holocene Epoch: It is the current period of geologic time. The term was introduced by Gervais in 1869 and was accepted as part of valid geological nomenclature by the International Geological Congress in 1885. Another term that is sometimes used is the Anthropocene Epoch, because its primary characteristic is the global changes caused by human activity. The Holocene Epoch began 12,000 to 11,500 years ago at the close of the Paleolithic Ice Age and continues through today. It is marked by a significant warming trend and relative climate stability compared to the previous glacial period. The sediments of the Holocene, both continental and marine, cover the largest area of the globe of any epoch in the geologic record, but the Holocene is unique because it coincides with the late and post-Stone Age history of humankind. Among interglacial periods, the Holocene is unique as the period in which more complex human civilisations and agriculture developed. Hence both statements are correct.

Only two Explanation : At a review meeting chaired by the Union Ministry of Home Affairs recently, the Army sought the inclusion of additional police station limits in Manipur Valley under the ambit of the Armed Forces (Special) Powers Act (AFSPA). About Armed Forces (Special) Powers Act (AFSPA): It is a law enacted by the Parliament in 1958 which gives the armed forces special powers and immunity to maintain public order in “disturbed areas”. When is it applied? It can be applied only after an area has been declared “disturbed” under section 2 of the Act. Jurisdiction: Both the State and Union Governments can issue notifications declaring certain areas as “disturbed”, granting the armed forces the authority under AFSPA. For Nagaland and Arunachal Pradesh, the Union Ministry of Home Affairs (MHA) issues periodic notifications. Disturbed Areas under AFSPA: Defined under Section 3 of the Act, a “disturbed area” is where the use of armed forces is deemed necessary to support civil authorities in maintaining law and order. Declaration of Disturbed Areas: An area can be declared disturbed due to conflicts or disputes between various religious, racial, linguistic, regional, or caste-based communities. The central government, Governor of the state, or the administrator of the Union Territory can declare the whole or part of a state or union territory as a disturbed area. Once declared, the region is maintained as disturbed for at least three months under The Disturbed Areas (Special Courts) Act, 1976. The scope and duration of AFSPA can vary depending on the region’s security situation. The ‘special powers’ of armed forces under AFSPA are: They have the authority to prohibit a gathering of five or more persons in an area, can use force or even open fire after giving due warning if they feel a person is in contravention of the law. If reasonable suspicion exists, the army can also arrest a person without a warrant, enter or search a premises without a warrant, and ban the possession of firearms. Any person arrested or taken into custody may be handed over to the officer in charge of the nearest police station along with a report detailing the circumstances that led to the arrest. These armed forces are immune from prosecution unless the Union Government provides sanction to the prosecuting agencies. Where is AFSPA in force now? Apart from Nagaland, the AFSPA is currently in force in Jammu and Kashmir, Assam, and Manipur except in Imphal, and Arunachal Pradesh. Hence option b is the correct answer.

global deep-sea research initiative Explanation : Scientists have discovered dozens of new species on the newly exposed seafloor left behind by the A-84 iceberg, which broke away from the George VI Ice Shelf on January 13, 2025. What is an Ice Shelf? An ice shelf is a floating mass of glacial ice, fed from land by tributary glaciers, and extending over the sea above an ice shelf cavity. Key Ice Sheets: Antarctica and Greenland Ice Sheets hold two-thirds of Earth’s freshwater. The West Antarctic Ice Sheet is one of the largest. Role in Sea Level Changes: When ice sheets gain mass, global sea levels fall. When ice sheets lose mass, global sea levels rise. Scientific discoveries under George VI Ice Shelf: Expedition: Conducted as part of Challenger 150, a UNESCO-endorsed global deep-sea research initiative. Remotely Operated Vehicle (ROV) SuBastian explored the seabed 1,300 meters deep. Key findings: Diverse ecosystem: Found icefish, giant sea spiders, corals, sponges, and octopi. New species: Scientists believe they discovered previously unknown marine species. Jellyfish discovery: A giant phantom jelly was recorded, growing up to a meter wide. Unusual nutrient supply: Despite being cut off from surface nutrients for centuries, life thrives—possibly due to ocean currents or glacial melt water transporting essential nutrients. About George VI Ice Shelf: Location: Lies between Alexander Island and the Antarctic Peninsula. Size: Covers 24,000 sq. km, making it the second-largest ice shelf in the region. Ice flow: Receives ice from both the Antarctic Peninsula and Alexander Island. Unlike most ice shelves, it is laterally constrained (trapped between landmasses) instead of freely flowing into the ocean. It blocks epishelf lakes (trapped freshwater bodies between ice shelves and land). Situated at the -9°C mean annual air temperature isotherm, a critical threshold beyond which ice shelves are prone to collapse. Susceptible to melting from both atmospheric warming and warm ocean currents. Hence option a is the correct answer.

Increasing manufacturing’s share in India’s GDP to 25% by 2025 Explanation : India’s $23 billion PLI scheme to rival China factories to lapse after it disappoints. Why in the News? The $23 billion Production-Linked Incentive (PLI) scheme, launched in 2020 to boost domestic manufacturing and reduce dependence on China, is set to lapse as many firms failed to meet production targets. The scheme was aimed at increasing manufacturing’s share in India’s GDP to 25% by 2025, but it has declined from 15.4% to 14.3% instead. Only 37% of the expected production target was achieved, with $151.93 billion worth of goods manufactured by October 2024. Delays in subsidy payouts and excessive bureaucracy hampered the scheme’s effectiveness. About the PLI Scheme: The Production Linked Incentive (PLI) scheme was launched to boost domestic manufacturing, increase import substitution, and generate employment. The scheme initially targeted three industries: Mobile and Allied Component Manufacturing, Electrical Component Manufacturing and Medical devices. Later, it was expanded to 14 key sectors. Under this scheme, Domestic and Foreign companies receive financial incentives based on a percentage of their incremental revenue for up to five years. Performance of the PLI Scheme: Mobile Phones: Major success – Production rose 63% from 2020-24, reaching $49 billion. Apple and Samsung dominate exports. Pharmaceuticals: Strong growth – Exports nearly doubled to $27.85 billion (2023-24). Food Processing: Exceeded production targets, but some firms missed subsidy eligibility due to investment non-compliance. Steel & Solar Panels: Lagging sectors – 14 out of 58 approved steel projects withdrawn, 8 out of 12 solar firms unlikely to meet targets. Textiles & IT Hardware: Slow growth, struggling to compete with China's lower production costs. 94% of the $620 million incentives disbursed (April-Oct 2024) went to pharmaceuticals and mobile phones, highlighting uneven sectoral success. Hence option d is the correct answer. News: https://www.thehindu.com/business/Economy/indias-23-billion-pli-scheme-to-rival-china-factories-to-lapse-after-it-disappoints/article69357682.ece

Mountains and Glaciers - Water Towers Explanation : The 2025 UN world water development report says that Retreating glaciers threaten the food and water supply of 2 billion people around the world. About United Nations World Water Development Report (WWDR): WWDR is UN-Water’s flagship report on water and sanitation issues. It offers an authoritative and comprehensive assessment of the overall state, use and management of the world’s freshwater resources. Launched on World Water Day (March 22), the report focuses on a different theme each year and gives policy recommendations to decision-makers by offering best practices and in-depth analyses. The WWDR is published by UNESCO on behalf of UN-Water and its production is coordinated by the UNESCO World Water Assessment Programme. Highlight of the WWDR 2025: Theme: Mountains and glaciers - Water towers The report says that “all mountain ranges” have shown evidence of warming since the early 20th century. It warns that, as global temperatures rise, more mountain precipitation will fall as rain instead of snow, causing snowpacks to thin and melt earlier in the year. It finds that receding snow and ice cover in mountain regions could have“severe” consequences for people and nature. This acceleration in snowpack melt often causes river flow to increase in glacier-fed water basins and rivers in the short term. However, once the snow melts beyond a certain threshold, a “peak water” point is passed and river flow declines again. The report says there is “strong evidence” that this “peak water” point has already been passed in the glacial-fed rivers of the tropical Andes, western Canada and the Swiss Alps. Meanwhile, many glaciers have disappeared entirely. For example, Colombia has lost 90% of its glacial area since the mid-19th century, according to the report. It warns that, as the climate warms, many glaciers will “inevitably” disappear over the coming decades. It points to projections that suggest that warming of 1.5-4C will cause glaciers to lose 26-41% of their 2015 mass by 2100. The report highlights a wide range of impacts, including reduced water for drinking and agriculture, stress on local ecosystems and increased risk of “devastating” glacial lake outburst floods (GLOFs). Retreating glaciers threaten the food and water supply of 2 billion people around the world. Two-thirds of all irrigated agriculture in the world is likely to be affected in some way by receding glaciers and dwindling snowfall in mountain regions, driven by the climate crisis. Hence option c is the correct answer. News: https://www.livescience.com/planet-earth/fossils/refuge-from-the-worst-mass-extinction-in-earths-history-discovered-fossilized-in-china

Neither 1 nor 2 Explanation : A dog-faced water snake (Cerberus rynchops) has been recorded for the first time in Northeast India, far from its known coastal habitat. About Dog-Faced Water Snake: It is a rear-fanged, mildly venomous, semi-aquatic snake. It belongs to the family Homalopsidae, which refers to Indo-Australian rear-fanged water snakes. Scientific Name: Cerberus rynchops Distribution: It typically resides in mangroves, coastal mudflats, and, and estuarine habitats throughout Southeast Asia and northern Australia. In India, it has been recorded in coastal regions such as Gujarat, Maharashtra, Kerala, Odisha, Tamil Nadu, Telangana, and the Andaman and Nicobar Islands. They spend the majority of their life in some type of water. Salt glands are what allow them to live in marine environments because they can expel salt through them in order to survive. The species hunts fish and crustaceans in shallow waters employing a ‘sit-and-wait’ strategy to ambush prey. Features: They can grow to about 1m long. They are characterized by a wide head and snout, which is where the epithet "dog-faced water snake" comes from. They are striped and dark brown with a white underbelly. The snake is adapted for slow-moving, shallow, and murky waters. It can swim well. On soft mud, it moves quickly by sidewinding. Conservation Status: IUCN Red List: Least Concern Hence both statements are not correct. News: https://www.thehindu.com/news/national/assam/northeast-records-first-dog-fa

Answer 180

The legal reasoning that forms the binding part of a judgment. Explanation : The Kerala High Court recently reaffirmed that any tax assessment orders passed on ignorance of binding precedents set by higher courts are violative of the doctrine of precedent and thus unsustainable. About Doctrine of Precedent: The doctrine of precedent is the custom of the courts to stand by previous decisions, so that once a point of law is decided upon by a court, then the same law must be applied to future cases with materially similar facts. It is often referred to as 'stare decisis'. The lower courts will take account of and follow the decisions made by the higher courts. It ensures consistency, predictability, and stability by obligating courts to follow the legal principles established in previous decisions. The foundation of the doctrine of precedent lies in Article 141 of the Indian Constitution. This article states that the law declared by the Supreme Court is binding on all courts within India. Essentially, lower courts must follow the legal interpretations and judgments laid down by the Supreme Court. Key Aspects: Ratio Decidendi: The legal reasoning that forms the binding part of a judgment. Courts must follow this in similar cases. Obiter Dicta: Non-essential remarks made by the court. Although not binding, they can be influential in future cases. Landmark Judgment: The State of Orissa v. Mamata Patnaik (1978) case highlighted the significance of following precedent. The Supreme Court emphasised that adherence to established legal principles ensures consistency in the application of law. Hence option b is the correct answer.

Answer 190

2 only Explanation : India recently has imposed anti-dumping duty on five Chinese goods, including vacuum flasks and aluminium foil. About Anti-Dumping Duty: It is a protectionist tariff that a domestic government imposes on foreign imports that it believes are priced below fair market value. Dumping is a process wherein a company exports a product at a price that is significantly lower than the price it normally charges in its home (or its domestic) market. The duty is priced in an amount that equals the difference between the normal costs of the products in the importing country and the market value of similar goods in the exporting country or other countries that produce similar products. It is imposed to protect local businesses and markets from unfair competition by foreign imports. Thus, the purpose of anti-dumping duty is to rectify the trade distortive effect of dumping and re-establish fair trade. The use of anti dumping measures as an instrument of fair competition is permitted by the WTO. While the intention of anti-dumping duties is to protect local businesses and markets, these tariffs can also lead to higher prices for domestic consumers. In the long-term, anti-dumping duties can reduce the international competition of domestic companies producing similar goods. In India Anti-dumping and Anti-subsidies are administered by the Directorate General of Trade Remedies (DGTR), which is operated by the Ministry of Commerce and Industry, and headed by the “Designated Authority”. The Department of Commerce recommends the Anti-dumping duty, and the Ministry of Finance levies it. What is Countervailing duty (CVD)? It is a specific form of duty that the government imposes to protect domestic producers by countering the negative impact of import subsidies. CVD is thus an import tax by the importing country on imported products. The duty nullifies and eliminates the price advantage enjoyed by an imported product. The WTO permits the imposition of CVD by its member countries. Countervailing duty v/s Anti-dumping duty: Anti-dumping duty is imposed to prevent low-priced foreign goods from damaging the local market. On the other hand, CVD will apply to foreign products that have enjoyed government subsidies, which eventually leads to very low prices. While the anti-dumping duty amount depends on the margin of dumping, the CVD amount will completely depend on the subsidy value of the foreign goods. Hence only statement 2 is correct.

Answer 191

Both 1 and 2 Explanation : The Telangana Socio-Economic Outlook 2025 report reveals that Hyderabad is experiencing increased nighttime heat stress due to the urban heat island effect. About Urban Heat Island (UHI): The UHI effect is a climatic phenomenon observed in urban areas, where temperatures are significantly higher than in surrounding rural areas. This discrepancy in temperature is attributed to human activities and urban development, which alter land surfaces and environments. It is the result of an accumulation of factors, the main ones being: Reduced green spaces and natural soils: Urbanization contributes to shrinking vegetation in cities (trees, lawns, etc.), resulting in insufficient shading and evapotranspiration, a process that naturally cools the air. Density of buildings and infrastructure: Concrete or asphalt buildings and roads store more heat than vegetated areas, thus exacerbating urban warming. Urban layout: narrow streets and tall buildings create urban canyons where warm air is less able to circulate, amplifying the effect of UHIs. Heat released by human activities: Road traffic, air conditioning systems, and industrial activities generate heat, which is then trapped by greenhouse gases (such as carbon dioxide) that act as a barrier. The combined effect of all these factors, together with global warming and increasingly high temperatures, leads to the development of this urban microclimate. The term “Urban Heat Island” originates from the visual representation of temperature distribution maps, where urban areas are depicted as “islands” of higher temperatures amidst cooler rural “seas.” The heat of the sun is absorbed during the day, only to be released very slowly at night, which limits the cooling of the air, thus contrasting with the cooling in the outlying rural areas. Temperature differences at night can be as much as 12°C. Hence both statements are correct.

Answer 198

Only two Explanation : India will host the FATF Private Sector Collaborative Forum 2025 in Mumbai, addressing global priorities such as payment transparency, financial inclusion, and digital financial system transformation. About the Financial Action Task Force (FATF): FATF is an intergovernmental policy-making and standard-setting body dedicated to combating money laundering and terrorist financing. Objective: To establish international standards and to develop and promote policies, both at national and international levels, to combat money laundering and the financing of terrorism. FATF develops and promotes policies across various countries and jurisdictions. Origin: It was established in 1989 during the G7 Summit in Paris in response to a growing concern about money laundering. In 2001, its mandate expanded to include terrorism financing. Headquarters: Paris, France. Members: To become a member, a country must be considered strategically important (large population, large GDP, developed banking and insurance sector, etc.), must adhere to globally accepted financial standards, and be a participant in other important international organizations. FATF members include 39 countries, including the United States, India, China, Saudi Arabia, Britain, Germany, France, and the EU as such. In addition, more than 180 countries worldwide are affiliated with the FATF through a network of FATF-style regional bodies (FSRBs). India became a member of FATF in 2010. India is also a member of two FATF Style Regional Bodies (FSRBs)-the Asia Pacific Group (APG) and the Eurasian Group of Combating Money Laundering and Financing of Terrorism (EAG). The FATF researches how money is laundered and terrorism is funded, promotes global standards to mitigate the risks, and assesses whether countries are taking effective action. FATF regularly publishes reports that raise awareness about the latest money laundering, terrorist financing, and proliferation financing techniques so that countries and the private sector can take the necessary steps to mitigate these risks. The FATF Recommendations are recognised as the global anti-money laundering (AML) and counter-terrorist financing (CFT) standard. Once a member, a country or organization must endorse and support the most recent FATF recommendations and commit to being evaluated by (and evaluating) other members. The FATF holds countries to account that do not comply with the FATF Standards. If a country repeatedly fails to implement FATF Standards, then it can be named a Jurisdiction under Increased Monitoring or a High-Risk Jurisdiction. These are often externally referred to as “the grey and black lists”. What are FATF 'grey list' and 'blacklist'? Black List: Countries known as Non-Cooperative Countries or Territories (NCCTs) are put on the blacklist. These countries support terror funding and money laundering activities. The FATF revises the blacklist regularly, adding or deleting entries. Grey List: Countries that are considered a safe haven for supporting terror funding and money laundering are put on the FATF grey list. This inclusion serves as a warning to the country that it may enter the blacklist. Three countries-North Korea, Iran, and Myanmar, are currently on FATF’s blacklist. Consequences of being on the FATF blacklist: No financial aid is given to them by the International Monetary Fund (IMF), the World Bank, the Asian Development Bank (ADB), and the European Union (EU). They also face a number of international economic and financial restrictions and sanctions. Hence option b is the correct answer.

Answer 199

Both 1 and 2 Explanation : According to a new study, permafrost covers 64.8% of the total area of J & K and Ladakh. About Permafrost: Permafrost is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight. Where are they found? These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles. They can be found on land and below the ocean floor. It can extend down beneath the earth’s surface from a few feet to more than a mile, covering entire regions, such as the Arctic tundra, or a single, isolated spot, such as a mountaintop of alpine permafrost. Permafrost covers large regions of the Earth. Almost a quarter of the land area in the Northern Hemisphere has permafrost underneath. What Is Permafrost Made Of? Permafrost is made of a combination of soil, rocks and sand that are held together by ice. The soil and ice in permafrost stay frozen all year long. Although the ground is frozen, permafrost regions are not always covered in snow. Near the surface, permafrost soils also contain large quantities of organic carbon—a material leftover from dead plants that couldn’t decompose, or rot away, due to the cold. Lower permafrost layers contain soils made mostly of minerals. A layer of soil on top of permafrost does not stay frozen all year. This layer, called the active layer, thaws during the warm summer months and freezes again in the fall. In colder regions, the ground rarely thaws—even in the summer. There, the active layer is very thin—only 4 to 6 inches (10 to 15 centimeters). In warmer permafrost regions, the active layer can be several meters thick. Hence both statements are correct.

Variations in DNA sequences among individuals Explanation : Why in the News? DNA fingerprints are widely used in forensic science, ancestry tracing, and biological research. DNA polymorphisms, which are variations in DNA sequences among individuals, form the basis of DNA fingerprinting and are crucial for identifying individuals, solving crimes, and studying genetic relationships. What is DNA? DNA (Deoxyribonucleic Acid) is the genetic material present in almost all cells of the human body (skin, blood, bone, teeth, etc.). Humans have 46 DNA molecules (chromosomes): 23 chromosomes inherited from the father (via sperm). 23 chromosomes inherited from the mother (via the egg). Chromosomes contain genes, which carry instructions for traits like eye color, height, and susceptibility to diseases. What are DNA Polymorphisms? DNA polymorphisms are variations in DNA sequences among individuals. These genetic differences occur at specific locations in DNA and help differentiate one person from another. DNA polymorphisms allow scientists to determine: Parentage (paternal/maternal lineage). Genetic ancestry. Identity verification through DNA fingerprinting. What are Short Tandem Repeats (STRs)? STRs are short sequences of DNA bases (A, T, C, G) that repeat multiple times. Example: A repeated sequence like GATCGATCGATC (on the complementary strand, CTAGCTAGCTAG). Each person has a unique STR pattern, making STRs highly useful for: Forensic investigations. Criminal identification. Parent-child relationship testing. STRs are inherited, so they provide valuable insights into ancestry and genetic inheritance. How is DNA Copied for Analysis? (PCR Method) Polymerase Chain Reaction (PCR) is a technique used to amplify DNA segments, making millions of copies. Steps of PCR: DNA Extraction: Scientists collect DNA from blood, bones, saliva, or skin cells. Denaturation (95°C): DNA strands are heated to separate them. Annealing (60°C): Short DNA primers bind to target sequences. Extension (72°C): DNA polymerase enzyme adds complementary bases, creating new DNA strands. Cycling Process: The steps are repeated, rapidly increasing the DNA copies. PCR is essential for DNA fingerprinting, criminal investigations, and medical research. What is a DNA Fingerprint? A DNA fingerprint is a unique genetic profile based on STR variations. It is created using Capillary Electrophoresis: DNA fragments move through a capillary under an electric field. Smaller fragments travel faster, separating different STR patterns. The final DNA profile is unique to each person (except identical twins). Sources of DNA for fingerprinting: Teeth, bones, blood, saliva, sweat, semen, skin cells. Hence option c is the correct answer.

Answer 222

All four Explanation : The AMoRE experiment in South Korea has reported no evidence of neutrinoless double beta decay (0νββ). About Neutrinos Neutrinos are nearly massless, electrically neutral subatomic particles that interact extremely weakly with matter. They belong to the lepton family, which is not subject to the strong nuclear force. Sources: Neutrinos are produced in radioactive decay, supernova explosions, nuclear fusion in the Sun, and cosmic ray interactions. Abundance: They are the second most abundant subatomic particle in the universe after photons. Every second, 100 trillion neutrinos pass harmlessly through the human body. Challenges in Detection: Due to their weak interaction with matter, detecting neutrinos requires highly sensitive detectors and long observation times. Neutrinos and the Majorana Hypothesis Majorana Particles: Most subatomic particles have distinct anti-particles (e.g., the electron’s anti-particle is a positron). However, Majorana particles are their own anti-particles. If neutrinos are found to be Majorana particles, it would have profound implications for particle physics and could explain why the universe has more matter than antimatter. What is Double Beta Decay? Beta Decay: A process where an unstable atomic nucleus converts a neutron into a proton, emitting an electron and an anti-neutrino. Double Beta Decay (2νββ): A rare nuclear decay where two neutrons transform into two protons, emitting two electrons and two anti-neutrinos. This process has been observed in certain isotopes. Neutrinoless Double Beta Decay (0νββ): A hypothetical decay where only two electrons are emitted, and no neutrinos. This could only happen if neutrinos and anti-neutrinos are the same particle (Majorana particles). If 0νββ is observed, it could also help determine the absolute mass of neutrinos. AMoRE Experiment and Its Findings Location: South Korea. Method: The experiment observed 3 kg of molybdenum-100 (Mo-100), a nucleus known to undergo double beta decay. Temperature: The detectors were cooled to fractions above absolute zero to detect tiny energy changes. Result: No evidence of 0νββ was found, but scientists set an upper limit: If 0νββ exists, Mo-100 nuclei would decay through this process in at least 10²⁴ years (a trillion times longer than the age of the universe). The neutrino mass is estimated to be below 0.22-0.65 billionths of a proton’s mass, but not necessarily zero. Hence option d is the correct answer.

Removes the "larger public interest" clause for disclosing personal data Explanation : Concerns Over Section 44(3) of the Digital Personal Data Protection (DPDP) Act. Why in the News? Section 44(3) of the DPDP Act, 2023 has sparked controversy as activists claim it weakens the Right to Information (RTI) Act, 2005. Congress leader Jairam Ramesh has urged the Minister of Electronics and Information Technology (MeitY) to repeal this provision, arguing that it would "destroy" the RTI Act. RTI activists, including Aruna Roy, Nikhil Dey, Prashant Bhushan, and Anjali Bhardwaj, have opposed the amendment, warning that it could restrict access to critical public information. What is Section 44(3) of the DPDP Act? The DPDP Act, 2023, received Presidential assent on August 11, 2023 and aims to regulate digital personal data processing while balancing individual privacy rights with lawful data processing needs. Section 44(3) amends Section 8(1)(j) of the RTI Act, 2005, expanding the scope of denying information under the pretext of protecting personal data. The Change: Previous Section 8(1)(j) (RTI Act): Allowed exemption from disclosure only if the personal information was unrelated to public interest or caused unwarranted privacy invasion, unless larger public interest justified disclosure. Revised Section 8(1)(j) (DPDP Act): This removes the “larger public interest” clause and broadly exempts all personal information from disclosure under RTI. How Could This Affect RTI Requests? Before DPDP Act (RTI Act - Section 8(1)(j)) After DPDP Act (Section 44(3)) Personal information could be disclosed if public interest justified it. All personal information is exempt from disclosure, regardless of public interest. Example: A citizen could request details of public officials’ assets if corruption was suspected. Example: Such a request can now be denied, citing personal data protection. The balance between privacy and transparency was determined case-by-case. Blanket exemption for personal data, even if it concerns public officials. Hence option b is the correct answer.

An inherited autoimmune disorder Explanation : AI could speed up the diagnosis of coeliac disease, according to recent research. About Coeliac Disease: It is an inherited autoimmune disorder. Cause: It is caused by an immune reaction to eating gluten. Gluten is a protein found in foods containing wheat, barley, or rye. If you have celiac disease, eating gluten triggers an immune response to the gluten protein in your small intestine. Over time, this reaction damages your small intestine's lining and prevents it from absorbing nutrients, a condition called malabsorption. Symptoms: The intestinal damage often causes symptoms such as diarrhea, fatigue, weight loss, bloating, or anemia. It also can lead to serious complications if it is not managed or treated. In children, malabsorption can affect growth and development in addition to gastrointestinal symptoms. People with a first-degree relative with celiac disease (parent, child, sibling) have a 1 in 10 risk of developing celiac disease. Celiac disease can develop at any age after people start consuming gluten. It is estimated to affect 1 in 100 people worldwide. Treatment: There's no definite cure for celiac disease. But for most people, following a strict gluten-free diet can help manage symptoms and help the intestines heal. Hence option b is the correct answer.

South China Sea Explanation : China deployed two long-range H-6 bombers around the Scarborough Shoal recently, in Beijing's latest move to assert sovereignty over the hotly disputed atoll in the South China Sea. About Scarborough Shoal: The Scarborough Shoal (also known in English as the Scarborough Reef) is an oceanic coral atoll that developed on top of a seamount into a triangle shape in the eastern part of the South China Sea. It is located some 220 kilometers west of the Philippines’ Island of Luzon. It is the largest atoll in the South China Sea, submerged at high tide with few rocks above sea level. This atoll extends 18 km along its northwest-southeast axis and reaches 10 km along its northeast-southwest axis. The deep waters around the shoal make it a productive fishing area, rich in marine life, and the lagoon also contains many commercially valuable shellfish and sea cucumbers. The shoal is the source of an ongoing and, so far, unresolved dispute between the People’s Republic of China and the Philippines, with both countries claiming that the shoal lies within their territory and saying they have exclusive rights to access its waters. There are no structures built on Scarborough Shoal, but the feature is effectively controlled by China, which has maintained a constant coast guard presence at the feature since 2012. China, which now refers to the shoal as Huangyan Island, makes a historical claim to the area, stating that they can trace their ownership of the area back to the Yuan Dynasty of the 1200s. The Philippines claim the area on the basis of geography, as it is much closer to the Philippines’ main island of Luzon, which contains the capital, Manila, but lies over 500 miles from China. It is considered within the Philippines’ 200-nautical mile exclusive economic zone, based on the 1982 United Nations Convention on the Law of the Sea (UNCLOS). Hence option d is the correct answer.

Both 1 and 2 Explanation : A 7.7-magnitude earthquake struck central Myanmar on March 29, 2025, causing significant destruction in Mandalay and claiming at least 144 lives. About Earthquakes Earthquake: Sudden shaking or trembling of the Earth's surface due to the release of stored energy in the Earth's crust or upper mantle. Focus (Hypocentre): The point within the Earth where the earthquake originates. Epicentre: The point on the surface directly above the focus. Seismograph: An instrument used to detect and measure earthquakes. Isoseismic line: A line connecting points on the surface experiencing the same intensity. Causes of Earthquakes Fault zones: Most earthquakes occur along fault lines, where stress builds up due to tectonic movements. Major faults: Thrust faults (Convergent boundary) → Most powerful quakes (Magnitude 8+). Strike-slip faults (Transform boundary) → Horizontal movement (e.g., Sagaing Fault, San Andreas Fault). Normal faults (Divergent boundary) → Less intense quakes (Magnitude <7). Plate Tectonics: Tectonic movement at plate boundaries can trigger earthquakes: Convergent Boundaries → Subduction zones, causing megathrust earthquakes (e.g., 2004 Indian Ocean earthquake). Divergent Boundaries → Spreading ridges generate mild earthquakes. Transform Boundaries → Horizontal movement of plates leads to strike-slip earthquakes (e.g., Sagaing Fault, San Andreas Fault). Volcanic activity: Magma movement inside volcanoes can cause volcanic earthquakes. Myanmar has active volcanoes, contributing to seismic activity. Human-induced earthquakes: Mining, dam construction, and deep drilling can trigger artificial seismic activity. Why Does Myanmar Experience Frequent Earthquakes? Tectonic Setting: Myanmar lies at the junction of three major tectonic plates: Indian Plate (moving northward) Eurasian Plate (moving southward) Burma Microplate (moving eastward) The Sagaing Fault, a strike-slip fault, runs north-south through central Myanmar, making it highly prone to seismic activity. Hence both statements are correct.

It can also involve human cells, tissues, or organs that have had prior ex vivo (outside the body) contact with non-human animal cells or tissues. First attempts at xenotransplantation involving the human heart were made in the 1980s. Genetic modifications are required in animal organs to prevent immune rejection by the human body. Post-transplantation monitoring is crucial to ensure organ functionality and detect immune responses. Why Are Pigs Used for Xenotransplantation? Pig heart valves have been successfully used for human valve replacements for over 50 years. Anatomical and physiological similarities between pigs and humans make pigs ideal organ donors. Pigs are widely farmed, making organ availability cost-effective and scalable. The variety of pig breeds allows organ size to be matched with specific human requirements. Recent Advancements in Xenotransplantation First Genetically Modified Pig Heart Transplant (2022): A genetically modified pig heart was successfully transplanted into a human for the first time. The experiment demonstrated the potential of genetically modified pig organs for human transplantation. Gene-Modified Pig Liver Transplantation (2025): Chinese researchers from the Fourth Military Medical University, Xi’an successfully transplanted a gene-edited pig liver into a brain-dead human recipient. Key Genetic Modifications: Six genes are edited to prevent immune rejection. Human transgenes are inserted to enhance compatibility. Observations Over 10 Days: The pig liver produced bile and albumin, indicating basic functionality. Stable blood flow was maintained. No signs of rejection were observed due to immunosuppressants. The study was published in Nature. Potential Use: Gene-modified pig livers could serve as a "bridge therapy" for patients awaiting human organ transplants. However, long-term viability and full liver functionality remain uncertain. Hence option b is the correct answer.

1 only Explanation : Recently, the International Union for Conservation of Nature (IUCN) has issued a warning that Frankincense-producing trees (Boswellia species) are at risk of extinction. Five species on Socotra Island (Yemen) have moved from Vulnerable to Endangered, one species is now Critically Endangered, and three others have been assessed as Critically Endangered for the first time. What is Frankincense? Frankincense is an aromatic resin derived from trees of the Boswellia genus. It has been historically valued for use in incense, perfumes and traditional medicine. Cultural significance: It was one of the three gifts (Gold, Frankincense, and Myrrh) presented to Jesus by the Magi, as mentioned in the Bible. Why is Frankincense at Risk? Habitat destruction & overgrazing: Goats graze on young saplings, preventing tree regeneration. Traditional rotational grazing practices have declined, leading to overgrazing. Climate change & extreme weather: Frequent cyclones, flash floods, and landslides (2015, 2018) have damaged and uprooted trees. Prolonged droughts hinder sapling growth. Unsustainable Harvesting: Excessive tapping for resin extraction weakens trees and reduces seed production. Limited conservation measures: Lack of effective protective measures like fencing and regulated harvesting has worsened the crisis. Hence only statement 1 is correct.

2 only Explanation : About Bodh Gaya Temple: Buddhist monks under the All India Buddhist Forum (AIBF) have been protesting since February 2024, demanding the repeal of the Bodh Gaya Temple Act (BTA), 1949. What is the Bodh Gaya Temple Act (BTA), 1949? The Act established an eight-member management committee to oversee the temple. Equal representation was given to Hindus and Buddhists, but the District Magistrate (DM) was made the ex-officio chairperson. Since the DM historically came from the Hindu community, this created a perceived Hindu majority in temple administration. Buddhist organizations have long demanded full control over the temple, calling it Bodh Gaya Mahavihara. Historical Background of the Dispute Ancient Period: Emperor Ashoka built the original temple at Bodh Gaya in the 3rd century BCE. It remained a Buddhist religious center until the Pala dynasty. Medieval Period (13th Century): Bakhtiyar Khilji’s invasion led to the decline of Buddhism in India. 1590: A Hindu monk established the Bodh Gaya Mutt, leading to Hindu control over the temple. Colonial Period: British-era records refer to Bodh Gaya as a Hindu-controlled site. Post-Independence (1949): The Bihar Assembly passed the BTA to formalize temple management, transferring control to the new committee instead of a single Hindu authority. Government Interventions The BTA, 1949, was passed to resolve ongoing disputes between Hindu and Buddhist religious heads. 2013 Amendment: The Bihar government amended the rule, allowing the ex-officio chairman (DM) to be from any faith. Early 1990s: Bihar CM Lalu Prasad Yadav drafted the Bodh Gaya Mahavihara Bill, aiming to transfer temple management to the Buddhist community. The Bill prohibited Hindu idol immersions near the temple and Hindu marriages inside the premises. However, it was never passed and remains in cold storage. About the Mahabodhi Temple Complex The Bodh Gaya Temple is one of the four most sacred sites of Buddhism, marking the location where Buddha attained Enlightenment (Bodhi) along with: Lumbini (Buddha’s birthplace) Sarnath (Buddha’s first sermon) Kushinagar (Buddha’s parinirvana Location: Bodh Gaya, Bihar, on the banks of the Niranjana River. The temple is one of the oldest surviving brick structures in India. Originally built by Ashoka in the 3rd century BCE, the present structure dates to the 5th–6th centuries CE. UNESCO World Heritage Site since 2002. Architectural Features Grand Temple: A 50-meter-high pyramidal shikhara (tower) with intricate engravings and arch motifs. Four smaller towers, each topped with an umbrella-like dome, surround the central temple. Sacred Bodhi Tree: Believed to be a direct descendant of the original tree under which Buddha attained Enlightenment. Vajrasana (Diamond Throne): A stone slab marking the exact spot where Buddha meditated. Temple Shrine: Houses a yellow sandstone statue of Buddha, encased in glass. The 4.8-hectare complex includes ancient shrines and modern Buddhist structures built by devotees. Hence option b is the correct answer. News: What is the controversy over the Bodh Gaya temple? | Explained - The Hindu.

Both 1 and 2 Explanation : About Centrifuges: Iran’s uranium enrichment program has drawn global attention, with thousands of advanced centrifuges being deployed Centrifuges play a crucial role in uranium enrichment, which is necessary for nuclear power generation and weapons development. Natural uranium contains 99.3% U-238 and only 0.7% U-235. Since only U-235 is fissile, it must be enriched for use in reactors and weapons. Nuclear power reactors require uranium with 3-20% U-235, while nuclear weapons need 90% enrichment. Iran’s uranium enrichment program has drawn global attention, with thousands of advanced centrifuges being deployed. What is a Centrifuge? A centrifuge is a device that separates substances based on density using centrifugal force. Used extensively in scientific research, medical applications, and nuclear technology. How Centrifuges Work in Uranium Enrichment Uranium conversion: Uranium is converted into uranium hexafluoride (UF₆) gas. Centrifugation process: UF₆ gas is introduced into high-speed centrifuges spinning at 50,000 RPM (revolutions per minute). Heavier U-238 isotopes move outward, while lighter U-235 isotopes concentrate towards the center. Gradual Enrichment: The U-235-rich fraction is transferred to additional centrifuges to increase purity further. Over multiple separation stages, uranium is enriched to the desired levels. Key Components of a Centrifuge Rotor: The spinning component that creates centrifugal force. Chamber: Holds the uranium gas for separation. Material: Typically made of carbon fiber or other lightweight yet strong materials to withstand high speeds. Hence option c is the correct answer. News: Centrifuge: getting to the good uranium - The Hindu.
