UPSC Current Affairs Quiz : 9 April 2026

Solution: D

NATGRID is an intelligence-sharing network established by the Government of India to enhance counter-terrorism capabilities. It connects multiple databases of core security agencies to facilitate real-time access to information for investigation and analysis.

It was conceptualized in the aftermath of the 2008 Mumbai terror attacks to address gaps in intelligence coordination.

• Nodal Ministry: Ministry of Home Affairs (MHA)
• Nature: Intelligence database integration platform (not an investigative agency)
• Objective: To link fragmented databases for swift retrieval of information related to suspects, terrorists, and criminal networks
• Access: Available only to authorized security and intelligence agencies

• Statement-I is incorrect because NATGRID does not utilize a centralized database to store records. Instead, it uses a federated database architecture. This means that the data stays with the original providers (such as banks, airlines, or the Income Tax department), and NATGRID merely provides a platform to access it when needed.
• Statement-II is correct. NATGRID functions as a middleware interface that allows 11 specified central agencies to query across 21 categories of data. This architecture is designed to break information silos between agencies like the Intelligence Bureau (IB) and the Research and Analysis Wing (R&AW) to prevent intelligence failures such as those witnessed during the 26/11 attacks.
• Authorized users include agencies like the NIA, CBI, and DRI. Recently, access was expanded to state police units at the Superintendent of Police (SP) rank.

Solution: C

Chlorpyrifos is a widely used organophosphate insecticide that has been subject to regulatory restrictions in several countries due to health and environmental concerns.

• Statement 1 is Correct. Chlorpyrifos inhibits acetylcholinesterase, causing accumulation of acetylcholine at synapses. This leads to continuous nerve impulse transmission, paralysis, respiratory failure, and death in pests. The inhibition is functionally irreversible once “aging” of the enzyme–organophosphate complex occurs.

Statement 2 is Correct. Recent scientific assessments indicate that chlorpyrifos demonstrates characteristics of persistence, bioaccumulation, toxicity, and long-range environmental transport (LRT). Monitoring data have detected it in remote regions, including the Arctic, supporting its ability to travel far from source regions. Although tropical climatic conditions may accelerate degradation (an argument raised by some countries), global scientific evaluation under the Stockholm Convention process recognizes its potential for wide environmental distribution.

Solution: B

• Kali Tiger Reserve is a premier protected area in the Uttara Kannada district of Karnataka.
• Statement 1 is correct. It was originally notified as the Dandeli-Anshi Tiger Reserve before being renamed to Kali Tiger Reserve in 2015 to better reflect the importance of the Kali River, which acts as the hydrological lifeline for the entire ecosystem.
• Statement 2 is correct. The reserve is famous for its Black Panthers (melanistic leopards); the high humidity and dense forest cover of the Western Ghats in this region favor the expression of this phenotype.

Statement 3 is correct. The reserve is located in the biologically sensitive Western Ghats range and comprises two contiguous protected areas: the Dandeli Wildlife Sanctuary and the Anshi National Park. The vegetation here ranges from moist deciduous to semi-evergreen, with rare and excellent patches of true evergreen forests in the westernmost valleys.

Solution: C

• Lake Natron, a highly alkaline salt lake in northern Tanzania, is the single most important breeding site for the Lesser Flamingo. Approximately 75% of the world’s population of this species is born at Lake Natron.
• The lake’s unique chemistry, with a pH as high as 12 and temperatures reaching 60°C, creates a caustic environment that is lethal to most other life forms. This extreme environment serves as a natural fortress, protecting the flamingo nests on isolated salt islands from predators like jackals and hyenas who cannot cross the caustic brine.

The flamingos thrive here because they have adapted to feed on Spirulina (cyanobacteria), which flourishes in the mineral-rich waters and gives the lake its characteristic red and orange hues. The lake gained international fame through the photographs of Nick Brandt, which showed animals that had died in the water and been “calcified” or naturally mummified by the high mineral content.

Solution: B

Statement 1 is correct; India’s National Agroforestry Policy 2014 was a global first, setting a framework to integrate trees on farms for ecological and economic stability.

Statement 2 is correct; the Model Rules 2025 for Felling of Trees in Agricultural Land were issued to address the “cumbersome process” of obtaining permits, standardizing registration, and simplifying the transit and certification of timber. This is a critical reform to promote “Trees Outside Forests.”

Statement 3 is incorrect because agroforestry currently occupies approximately 8% of India’s geographical land area, not 25%. While the government aims to increase this coverage significantly through missions like the Green India Mission (GIM) and PMDDKY, the current footprint remains much smaller than a quarter of the country.

Solution: A

• Statement 1 is correct because the Biopharma SHAKTI initiative is designed to transition India from a low-cost generic producer to a global hub for high-value biologics and biosimilars, medicines derived from living organisms.
• Statement 2 is correct as it utilizes a “triple-helix” approach, fostering collaboration between government regulators, academic researchers, and industrial manufacturers to translate lab research into market-ready products.
• Statement 3 is incorrect because the specific target set by the government is to capture 5% of the global biopharmaceutical market share, not 50%. The scheme is supported by a ₹10,000 crore outlay over five years and focuses on reducing import dependence for complex therapies like those used in cancer and rheumatoid arthritis. It also includes regulatory strengthening by adding specialized personnel to the CDSCO to align approval timeframes with global standards.

Solution: C

• Statement I is correct; the BioE3 policy stands for Biotechnology for Economy, Environment, and Employment, aiming to boost high-performance biomanufacturing.
• Statement II is also correct as it outlines the mechanism—the establishment of bio-AI hubs and biofoundries—which serves as the technological engine to achieve the goals of Statement I.
• However, Statement III is incorrect. The BioE3 policy is an initiative of the Department of Biotechnology (DBT) under the Ministry of Science & Technology, not the Ministry of Environment. While the policy supports environmental goals (Bio-Environment), its administrative management is under Science and Technology.
• Therefore, only Statement II is a correct statement that explains the high-performance R&D objective of Statement I. The policy is designed to enable a transition from petroleum-based industries to circular bio-economies.

Solution: C

• Autophagy, which literally translates to “self-eating”, is a vital and healthy biological process.
• Statement 1 is correct as it acts as an “internal housekeeping” mechanism where the body identifies worn-out cell parts or pathogens and removes or repurposes them.
• Statement 2 is also correct because effective autophagy supports cellular regeneration, enhances mitochondrial health, and reduces inflammation, thereby slowing biological aging. When autophagy functions well, the body becomes more resilient against age-related decline.
• Statement 3 is incorrect because autophagy is generally a protective and survival-oriented process, not a harmful one. However, its impairment is linked to neurological decline and metabolic imbalances. The process is so significant to medicine and biology that the discovery of its mechanisms earned the Nobel Prize in Physiology or Medicine in 2016.
• Maintaining a dynamic equilibrium through autophagy allows cells to transition between building new proteins and recycling old ones to survive under stress conditions like fasting.

Solution: B

The World Audio Visual and Entertainment Summit (WAVES) is an international summit initiated by the Government of India to position India as a global hub for the media, entertainment, and creative economy.

• The WAVES Declaration is a collective commitment by participating nations at the summit to strengthen global cooperation in the creative sector.
• Statement 1 is correct; the declaration reaffirms the sector’s role in fostering cultural understanding and resilience in a post-pandemic world.
• Statement 2 is also correct; it emphasizes bridging the digital divide to ensure equitable participation across different communities.
• However, Statement 3 is incorrect. Far from prohibiting AI, the declaration affirms the responsible and ethical use of emerging technologies, including Artificial Intelligence, guided by transparency and accountability. The summit featured masterclasses on using generative AI for game development and creating AI avatars, reflecting the belief that creativity is now inseparable from technology. Highlighting ‘Ethical AI’ rather than ‘AI Prohibition’ is a key conceptual distinction in modern digital policy.

Solution: C

• Vikramashila University was a premier center of learning during the Pala period.
• Statement 1 is correct as it was founded by King Dharmapala to serve as a superior alternative to Nalanda, which was thought to be in decline.
• Statement 2 is correct; Vikramashila was specifically famous as a major center of Tantric Buddhism and the Vajrayana tradition. Its specialization in esoteric studies was its primary academic hallmark.
• Recent government initiatives have aimed to revive the university on a 200-acre site in Antichak, Bhagalpur, with a ₹500 crore budget to restore its ancient glory. This restoration process mimics the successful revival of Nalanda University and aims to promote Buddhist tourism in Bihar while conducting further archaeological conservation.
