UPSC Quiz – 2026 : IASbaba’s Daily Current Affairs Quiz 27th October 2026

Solution (a)
Explanation: ICIMOD was established on 5 December 1983 with headquarters in Kathmandu, Nepal, as an intergovernmental knowledge and learning centre focused on the Hindu Kush Himalaya (HKH), with eight regional member countries: Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal and Pakistan, and a Board of Governors with representation from each of the eight member countries. Statement 2 is correct: the MoEFCC has tasked GBPNIHE, Almosa, Uttarakhand — established in 1988–89, headquartered at Kosi-Katarmal, Almora, and functioning as an autonomous research institute under MoEFCC — with coordinating ICIMOD’s activities in India through a dedicated ICIMOD cell that will screen and coordinate projects and bring Himalayan states, universities and research institutions onto a common platform. Statement 3 is incorrect: under the new mechanism, projects will undergo scientific and technical appraisal before final approval by a panel chaired by the MoEFCC Secretary — i.e., there is a national-level appraisal and approval layer, with standard operating procedures (SOPs) guiding project planning, approval, monitoring and evaluation. The initiative strengthens research on glaciers, water security, biodiversity, air pollution and disaster-risk reduction, including glacier retreat, GLOFs and extreme weather.
Why this question? The “direct approval by ICIMOD Board” trap tests the two-tier national coordination mechanism, with membership and institutional details adding precision.
Why important for UPSC? Himalayan ecosystems, regional cooperation and GLOF risks are recurring environment prelims themes.
PYQ Pattern Link: Similar to questions on ICIMOD’s membership and Himalayan research coordination mechanisms.

Solution (b)
Explanation: INS Vikrant — India’s first indigenously designed and constructed aircraft carrier, designed by the Navy’s Warship Design Bureau, built by Cochin Shipyard Limited, commissioned on 2 September 2022, with a length of 262.5 metres, displacement of approximately 45,000 tonnes, ~76% indigenous content, four gas turbines, maximum speed of 28 knots — operates using the STOBAR (Short Take-Off But Arrested Recovery) system, where aircraft take off using a ski-jump and land using arrestor wires. The Rafale-M was originally designed for French aircraft carriers using CATOBAR (Catapult Assisted Take-Off But Arrested Recovery). Hence, trials at the Shore-Based Test Facility (SBTF) at INS Hansa, Goa are necessary to validate ski-jump take-off performance, landing and arrestor-wire compatibility, and aircraft handling. The Navy is also examining minor carrier modifications to accommodate the aircraft, including its non-folding wings. India signed an inter-governmental agreement with France in April 2025 for 26 aircraft (22 single-seat fighters and 4 twin-seat trainers) at approximately ₹63,000 crore, with deliveries expected by end-2028 or early 2029. The Rafale-M is a twin-engine, multirole carrier-based fighter with reinforced landing gear, arrestor hook and specialised naval avionics, supporting air defence, maritime strike, reconnaissance and precision attacks. Options (a), (c) and (d) misstate the launch configurations, modification requirements or engine count.
Why this question? The STOBAR-CATOBAR mismatch is the core conceptual trap, explaining why trials are needed at all.
Why important for UPSC? Carrier aviation, India-France defence cooperation and indigenous carriers are recurring defence prelims themes.
PYQ Pattern Link: Similar to questions distinguishing STOBAR and CATOBAR configurations and their operational implications.

Solution (a)
Explanation: Ashoke Sen has become the first Indian physicist to receive the 2026 Oskar Klein Medal, receiving it and delivering the Oskar Klein Memorial Lecture in Stockholm on 22 October 2026. The medal was established in 1988, named after Swedish theoretical physicist Oskar Klein, and is awarded by Stockholm University and the Nobel Committee for Physics of the Royal Swedish Academy of Sciences to recognise distinguished contributions to theoretical physics; past recipients include Chen-Ning Yang (1988), Steven Weinberg (1989), Hans Bethe (1990), Stephen Hawking (2003), Peter Higgs (2009) and Kip Thorne (2016). Statement 2 is correct: Sen — ICTS-Infosys Madhava Chair Professor at the International Centre for Theoretical Sciences (ICTS), part of TIFR, Bengaluru — contributed S-duality (relationships between different descriptions of physical systems in string theory), the precise microscopic counting of black-hole states explaining black-hole entropy, string field theory (the mathematical framework for dynamics and interactions of strings), and establishing that the five perturbative string theories can be understood as different limits of a broader underlying framework. Statement 3 is incorrect on its core premise: string theory proposes that fundamental constituents of the universe are tiny, one-dimensional vibrating strings rather than point-like particles, and its major objective is to reconcile general relativity (gravity) with quantum mechanics — not classical mechanics.
Why this question? The “point-like particles” and “classical mechanics” reversals test core string theory concepts, while the award details add factual precision.
Why important for UPSC? Theoretical physics, Indian scientific achievement and international awards are recurring S&T prelims themes.
PYQ Pattern Link: Similar to questions on Indian scientists receiving international awards and their specific contributions.

Solution (b)
Explanation: Rugda is a wild, edible, subterranean fungus — commonly known as an earthstar mushroom — with the scientific name Astraeus hygrometricus, though related species such as Astraeus asiaticus are also locally identified as Rugda. It is found in Jharkhand and adjoining regions of Odisha, Chhattisgarh, West Bengal and Bihar, primarily in Sal-dominated forests of the Chhotanagpur Plateau, and appears beneath the forest floor after the first monsoon showers, collected for a short period. Its local names include Rugda, Rugra, Futka and Puttu. Ecologically, it forms an ectomycorrhizal association with the roots of Sal (Shorea robusta) trees — fungal filaments help trees absorb water and minerals, while the fungus receives carbohydrates from photosynthesis — contributing to nutrient cycling and soil health. It is difficult to cultivate artificially because it depends on a living forest ecosystem. Economically and socially, it is a Non-Timber Forest Produce (NTFP) providing seasonal income to tribal households, with traditional knowledge of locating and identifying edible mushrooms largely passed down through generations of women, adding nutritional diversity during the monsoon and agricultural lean season, and commanding high market value due to limited availability and high demand. Its conservation concerns include loss and fragmentation of Sal forests, erratic monsoon patterns, unsustainable harvesting, rising commercial demand and declining transmission of traditional ecological knowledge. Options (a), (c) and (d) misdescribe its cultivation status, edibility or habitat.
Why this question? The ectomycorrhizal-Sal association and NTFP-tribal livelihood linkage are the primary discriminators, with cultivation/poisonous/aquatic traps as distractors.
Why important for UPSC? Non-timber forest produce, tribal livelihoods and forest ecology are recurring environment prelims themes.
PYQ Pattern Link: Similar to one-liner questions on wild forest products, their ecological associations and livelihood significance.

Solution (a)
Explanation: Operation Trident was launched by the NCB on 23 October 2026, conducting simultaneous raids at 38 locations across Assam, Mizoram and Manipur to dismantle a transnational narcotics trafficking network operating along the India–Myanmar–Bangladesh corridor, allegedly trafficking methamphetamine and heroin originating in Myanmar through routes connecting Myanmar with Mizoram, Manipur, Assam and Tripura, with onward movement into mainland India and Bangladesh. The operation yielded 18 arrests, hawala transactions worth approximately ₹100 crore identified, 1,424 bank accounts frozen, properties worth ₹17.82 crore attached, and 500 detonators and ₹12 lakh in cash seized, involving the NCB, Mizoram Police, Enforcement Directorate (ED) and other enforcement agencies. Statement 2 is correct: the NCB was established on 17 March 1986 under Section 4(3) of the Narcotic Drugs and Psychotropic Substances (NDPS) Act, 1985, under the Ministry of Home Affairs, headquartered in New Delhi, as the apex coordinating and enforcement agency for combating drug trafficking and abuse, with functions including coordination among central and state drug-law enforcement agencies, intelligence collection and dissemination, international cooperation and investigation/enforcement. Statement 3 is incorrect: the operation specifically involved financial investigation — identifying links between drug trafficking, hawala transactions, shell entities and money mules — using intelligence gathering, financial profiling and digital forensics, with assets attached and accounts frozen. This reflects enforcement moving beyond drug seizures towards dismantling the financial backbone of criminal networks.
Why this question? The “solely drug seizures” trap reverses the operation’s defining feature (financial disruption), with NCB’s statutory basis adding precision.
Why important for UPSC? Drug trafficking, organised crime, financial investigation and border security are recurring internal security prelims themes.
PYQ Pattern Link: Similar to questions on NCB’s mandate, drug trafficking networks and financial investigation in organised crime.
