UPSC Quiz – 2026 : IASbaba’s Daily Current Affairs Quiz 5th November 2026

Solution (a)
Explanation: On 3 November 2026, MeitY released three indigenous AI foundation models under the IndiaAI Mission. EKA-1, developed by Soket Labs, is an open, sparse hybrid foundation model with 26.3 billion parameters, supporting all 22 scheduled Indian languages plus English, with key applications in mathematics, coding, reasoning and agentic AI, and deployment in private servers, private cloud and air-gapped environments. Dhīr 2B and Dhīr 5B, developed by ZenteiQ AiTech Innovations, are open-source multilingual models with 2 billion and 5 billion parameters respectively, supporting English and 10 Indian languages, designed for document automation, knowledge retrieval and citizen services, with on-device, offline and on-premise deployment. Statement 3 is the trap: “air-gapped deployment” means operating a computer system WITHOUT a direct connection to external networks, enhancing data security — not with a direct connection as stated. A foundation model is a large AI model trained on broad datasets adaptable to multiple downstream tasks; a sparse hybrid model selectively activates parts of the network for particular tasks. The initiative strengthens India’s technological and strategic autonomy in AI, supports multilingual digital services, and enables secure AI deployment in defence, banking, cybersecurity and government.
Why this question? The air-gapped definition reversal is the key trap; the model-wise developer, parameter and language specifications add precision.
Why important for UPSC? AI sovereignty, IndiaAI Mission and indigenous technology are emerging S&T prelims themes.
PYQ Pattern Link: Similar to questions on indigenous AI models, their developers and technical specifications.

Solution (a)
Explanation: Colletes inaequalis, the cellophane bee, belongs to the family Colletidae (order Hymenoptera) and is a solitary, ground-nesting bee — unlike honeybees, it does not live in large social colonies. It is found in North America and pollinates early-spring plants and crops, including red maple, willow and apple trees. Its unique nesting adaptation: female bees line underground nest chambers with a transparent, flexible, cellophane-like secretion consisting of polyester and silk, produced by a specialised gland called Dufour’s gland, protecting developing larvae from moisture and microbial exposure; its molecular structure resembles polyethylene, a widely used conventional plastic. A 2026 study published in PNAS found that this bee-produced polyester has a semicrystalline structure (crystalline and amorphous regions) and, in natural soil, its proportion in the nest lining declined from 73% to 40% by weight within four months; after seven months, cracks appeared, and by eleven months, the material became brittle and crumbled. Researchers aim to understand its degradation mechanism to develop durable yet biodegradable plastics. Options (b), (c) and (d) misstate its social structure, material production or habitat.
Why this question? The solitary-ground-nesting nature and the Dufour’s gland polyester secretion are the primary discriminators, with social/parasitic/aquatic traps.
Why important for UPSC? Biomimicry, biodegradable materials and pollinator biodiversity are emerging environment-S&T prelims themes.
PYQ Pattern Link: Similar to one-liner questions on biomimetic materials and insect-derived products.

Solution (d)
Explanation: The Pralay missile is a short-range, surface-to-surface quasi-ballistic missile developed by DRDO, with Research Centre Imarat, Hyderabad playing a key role. It has a range of 150–500 km, uses a solid-propellant rocket motor, is launched from a road-mobile launcher, can carry different types of conventional warheads, and uses advanced navigation and guidance systems for high-precision targeting, with the ability to manoeuvre during flight, making its trajectory less predictable than a conventional ballistic missile. Statement 2 is correct: a conventional ballistic missile follows a largely predictable, arcing trajectory after powered flight, while a quasi-ballistic missile follows a lower, more manoeuvrable trajectory and can alter its flight path, reducing the time available for an adversary’s detection and interception systems to respond. Statement 3 is correct: DRDO successfully test-fired Pralay from the Integrated Test Range (ITR), Chandipur, Odisha, on 3 November 2026, reportedly engaging two simulated targets at a distance of around 500 km. Its testing history includes the maiden successful flight test in December 2021, two consecutive tests in July 2025 validating maximum and minimum range capabilities, two missiles launched in quick succession from the same launcher during user evaluation trials in December 2025, and the November 2026 test. Its significance includes strengthening India’s indigenous precision-strike capabilities, enhancing operational flexibility and supporting defence indigenisation. All three statements are accurate.
Why this question? The quasi-ballistic flight profile distinction is the core conceptual trap, with range and test chronology adding precision.
Why important for UPSC? Missile technology, precision-strike capabilities and defence indigenisation are recurring defence prelims themes.
PYQ Pattern Link: Similar to questions on missile classifications (ballistic, cruise, quasi-ballistic) and their flight characteristics.

Solution (a)
Explanation: Siri cattle is an indigenous, zebu-derived cattle breed that is dual-purpose, used for milk and draught. Its native region is the Eastern Himalayas — primarily Sikkim, the Darjeeling hills of West Bengal and Bhutan — and it is also known as Trahbum. It is generally black or brown with white patches, though completely black or brown animals also occur, and its distinctive feature is a cervico-thoracic hump covered with a tuft of long hair. It is adapted to hilly terrain as small, sturdy animals, with bulls particularly used for draught work, and has a relatively low milk yield (reported average of approximately 425.8 kg per lactation). Crossbreeding, particularly with Jersey cattle, has contributed to the decline of pure Siri cattle, and a 2016 ICAR study identified the breed as endangered, reporting a decline from 79,000 animals in 2003 to 13,948 in 2012. On 2 November 2026, the Union Ministry of Fisheries, Animal Husbandry and Dairying launched the Siri Cattle Conservation Programme in Sikkim, laying the foundation stone for a Siri Bull Mother Farm at Chuchachen, Pakyong district, and announcing a Centre of Excellence for the breed, with scientific breeding proposed using IVF and improved germplasm multiplication. Options (b), (c) and (d) misstate its origin, species or purpose.
Why this question? The zebu-derived dual-purpose classification and the conservation decline figures are the primary discriminators, with exotic/buffalo/goat traps.
Why important for UPSC? Indigenous livestock breeds, genetic conservation and animal husbandry are recurring agriculture prelims themes.
PYQ Pattern Link: Similar to one-liner questions on indigenous cattle breeds, their native regions and conservation status.

Solution (d)
Explanation: The Sathyamangalam Tiger Reserve is located in Erode district, Tamil Nadu, covering approximately 1,411.6 sq km, established in 2008 and declared a tiger reserve in 2013, forming part of the Nilgiri Biosphere Reserve. Its landscape is the Eastern and Western Ghats link, forming an important wildlife corridor, with the Bhavani and Moyar river systems flowing through it and vegetation including tropical dry thorn, dry and moist deciduous, and semi-evergreen forests. Statement 2 is correct: it forms a crucial corridor connecting the Western Ghats and Eastern Ghats, supporting tigers, Asian elephants, leopards, Indian gaurs, sloth bears and other wildlife, and is important for maintaining connectivity between the Nilgiri and Eastern Ghats forest complexes. Statement 3 is correct: on 30 October 2026, the Madras High Court directed the immediate closure and subsequent demolition, in accordance with law, of 87 illegal resort establishments operating within the reserve area, as the Erode District Collector’s report stated that none had the required planning/building approval from the Directorate of Town and Country Planning or recorded permission from the Hill Area Conservation Authority (HACA) for land-use conversion. Unauthorised resorts and commercial land-use conversion can cause habitat fragmentation, disturbance, waste pollution and increased human–wildlife interaction; the matter is being monitored through further status reports, with the next hearing scheduled for 27 November 2026. All three statements are accurate.
Why this question? Tests the reserve’s corridor function, river systems and judicial action against illegal resorts—a multi-layered conservation question.
Why important for UPSC? Tiger conservation, wildlife corridors and judicial interventions in environmental protection are recurring environment prelims themes.
PYQ Pattern Link: Similar to questions on tiger reserves, their corridor connectivity and legal enforcement against encroachments.
