UPSC Current Affairs Quiz : 25 April 2026

Solution: A

• The National Institute for Pre-Clinical Research (NIPCR), located in Hyderabad’s Genome Valley, represents a strategic evolution in India’s biomedical landscape. Previously an animal resource facility under the Indian Council of Medical Research (ICMR), its upgrading to a national institute signifies a shift toward translational research.
• Statement-I is correct because the institute no longer merely maintains animal models but actively integrates them into the broader pipeline of drug and vaccine development.
• Statement-II is also correct as it defines the core functional mandate of NIPCR. The “bridge” mentioned refers to the pre-clinical phase, where the safety and efficacy of a molecule are tested before it is administered to humans.

This validation process is exactly why the facility was upgraded to a comprehensive hub; therefore, Statement-II directly explains why Statement-I (the transition to a hub) occurred. The institute supports Cell and Gene Therapies (CGT) and provides international-standard infrastructure to startups and academia, ensuring that “Made in India” medical products meet global safety benchmarks. By facilitating this transition, NIPCR reduces the gap between initial discovery and commercial clinical application, bolstering India’s self-reliance in medical technology.

Solution: A

• Statement 1 is incorrect; registration under the 2026 Rules is not universally mandatory. It is specifically required for esports or categories notified by the government based on scale and transaction value.
• Statement 2 is incorrect; the rules mandate a two-tier system for grievance redressal. Complaints are first handled internally by the gaming platform; if unresolved, they can be escalated to the OGAI and subsequently to an Appellate Authority designated under the rules, not directly to the Supreme Court as part of the specialized tier.
• Statement 3 is correct; the rules emphasize data localisation, requiring platforms to store all traffic and user data within India to ensure national security and regulatory oversight. The OGAI is a government-led body under MeitY with representatives from various ministries like Home, Finance, and Law.
• The rules also turn the payment layer into an enforcement tool, requiring banks to verify a game’s status before processing transactions. This effectively targets banned “Online Money Games” and addresses concerns related to financial fraud, addiction, and money laundering in the rapidly expanding gaming sector.

Solution: B

• Organoids are miniature, simplified versions of organs developed from stem cells under controlled laboratory conditions. They self-organize into three-dimensional structures that mimic key aspects of real human organs—such as the intestine, brain, liver, or lungs—in both architecture and function. Within New Approach Methodologies (NAMs), organoids serve as advanced in vitro systems that reduce reliance on animal testing and improve the accuracy of human-specific disease modeling and drug response prediction.
• Unlike option (a), they are not mechanical devices; unlike (c), they are not whole-animal models; and unlike (d), they are not purely computational simulations. Instead, they represent a bridge between traditional cell cultures and full organisms, enabling personalized medicine, toxicity testing, and developmental biology research with higher physiological relevance.

Solution: D

• The CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) is a global market-based measure developed by the International Civil Aviation Organization (ICAO). Its primary goal is to address the increase in total CO2 emissions from international aviation.
• Under CORSIA, airlines are required to offset any emissions that exceed a specific baseline. One of the most effective ways for airlines to do this is by using Sustainable Aviation Fuel (SAF). For a fuel to be recognized under this scheme, it must meet strict sustainability criteria to ensure it truly reduces the carbon footprint compared to traditional fossil fuels.
• India’s recent amendment to the ATF Control Order and the setting of blending targets (reaching 5% by 2030) are strategic moves to help Indian carriers comply with CORSIA. By using SAF, airlines can reduce their “offsetting” requirements, thereby reducing the financial burden of buying carbon credits on the open market. This aligns India with international environmental standards and ensures that Indian aviation remains competitive in a world increasingly focused on “net-zero” goals.

Solution: D

• The PMMY is specifically designed for non-corporate, non-farm small/micro-enterprises.
• Statement 1 is correct as truck operators and transport vehicle owners are a target group.
• Statement 2 is correct as small manufacturing units are central to the scheme.
• Statement 4 is correct as fruit and vegetable vendors are explicitly mentioned as beneficiaries. Statement 3 is incorrect because the scheme excludes corporate entities and farm-based activities (crop production). It aims to support the “service and manufacturing” sectors of the micro-economy. The scheme’s significance lies in its social inclusivity, with nearly 70% of accounts belonging to women entrepreneurs and over 50% to SC/ST/OBC This ensures that the benefits of the formal financial system reach the grassroots level. By focusing on “Yuva Shakti” and “Nari Shakti,” the PMMY serves as a catalyst for local employment generation and financial independence among marginalized sections.

Solution: B

• The International Election Visitors’ Programme (IEVP) is a flagship initiative of the Election Commission of India (ECI), not the United Nations. It is designed as an outreach platform to showcase India’s democratic machinery to the world. A central pillar of the IEVP is the demonstration of technological integration in elections. Delegates from various Election Management Bodies (EMBs) are given first-hand exposure to the functioning of Electronic Voting Machines (EVMs) and Voter Verifiable Paper Audit Trails (VVPATs). They also observe the use of digital tools like the cVIGIL app, which empowers citizens to report electoral malpractices in real-time.
• Beyond technology, the programme emphasizes South-South cooperation and Election Management Diplomacy. By inviting international observers to witness the scale and transparency of Indian elections, the ECI fosters a global community committed to democratic values. The observation includes visiting actual polling stations to understand queue management, security protocols, and the role of District Election Officers (DEOs).
• This transparency serves as a Soft Power tool, establishing India’s electoral process as a global benchmark for conducting free and fair elections involving millions of voters. The 2026 edition specifically covers the legislative assembly elections in states like Assam, Kerala, and West Bengal, providing a diverse geographic perspective on Indian federalism.

Solution: C

• Mangroves are highly specialized ecosystems that thrive in the harsh intertidal regions between land and sea.
• Statement 1 is correct as they require sheltered coastlines and slow-moving water to allow the accumulation of fine sediments.
• Statement 2 is also correct; mangroves are renowned as Blue Carbon sinks, capable of storing up to four times more carbon per hectare than typical tropical terrestrial forests. This makes them vital in the global fight against climate change.
• Statement 4 is correct, as the Sundarbans (spanning India and Bangladesh) is the only mangrove forest in the world inhabited by the Royal Bengal Tiger.
• However, Statement 3 is incorrect because not all mangroves use the same salt management strategy. While some species possess salt-excreting glands on their leaves, others utilize an ultra-filtration system in their roots to exclude salt from entering the plant entirely. Others still may store salt in older leaves or bark which then shed. Their survival also depends on Pneumatophores (aerial roots) for oxygen intake in anaerobic soils and vivipary, where seeds germinate while still attached to the parent tree.

These adaptations are essential for surviving the “physiological drought” caused by high salinity. Recent studies on critical slowing down in the Sundarbans suggest that these resilient systems are becoming more vulnerable to climate stress, taking longer to recover from extreme events.

Solution: B

• Mission MITRA (Mapping of Interoperable Traits and Response Assessment) is an indigenous Analog Space Mission launched by ISRO in 2026. It is not a joint mission with NASA. An analog mission is a terrestrial simulation that mimics the extreme conditions of space. The selection of Leh, Ladakh (at an altitude of approximately 3,500 meters) is strategic because its environment provides a natural laboratory for studying hypoxia (low oxygen), extreme cold, and isolation—all of which are significant stressors in spaceflight.
• The core objective of Mission MITRA is to study human factors that are critical for the success of the Gaganyaan programme and future long-duration missions like the Indian Space Station. Researchers monitor the Gaganyatris (crew) and ground control to understand team dynamics, communication lags, and cognitive performance under stress. By tracking “interoperable traits,” ISRO aims to see how team members support each other and maintain morale during periods of high pressure. This research is vital for developing protocols for aerospace medicine and ensuring the safety of astronauts during missions to the Moon or Mars. The data generated helps in designing closed-loop life support systems and refining the coordination between the crew and mission control, thereby reducing India’s dependence on foreign analog research data.

Solution: A

• The United Nations Security Council (UNSC) holds a unique position within the international legal architecture. While other UN bodies, such as the General Assembly, primarily issue recommendations, the Council has the authority to pass binding resolutions. This is the essence of Statement-I. The legal basis for this authority is found in Article 25 of the UN Charter, which explicitly states that the Members of the United Nations agree to accept and carry out the decisions of the Security Council. Therefore, Statement-II directly explains why the UNSC has the power mentioned in Statement-I.
• This binding nature is what allows the UNSC to impose sanctions, authorize the use of military force under Chapter VII, or establish peacekeeping operations. The Council’s primary mandate is the maintenance of international peace and security. However, the exercise of this power is often complicated by the Veto Power held by the five permanent members (P5). As seen in the 2026 West Asia conflict, a single veto from a P5 member (such as Russia or China) can block a substantive resolution even if it has the support of the majority. This often leads to a “watering down” of resolutions to reach a consensus, highlighting the tension between the Council’s legal authority and the geopolitical interests of its most powerful members.

Solution: C

• Succulence in mangroves refers to the development of thick, fleshy tissues—most commonly in the leaves—to store water. Although mangroves live in water, the high concentration of salt in their environment makes it difficult for them to absorb water through osmosis. This creates a condition known as physiological drought, where the plant is surrounded by water but can “thirst” because the water is too saline to be easily utilized. By storing water in their leaves, mangroves manage their internal water balance much like desert succulents (e.g., cacti).
• Option (a) describes vivipary, a unique reproductive strategy where seeds develop into seedlings (propagules) while still on the tree, allowing them to take root quickly once they drop into the mud. Option (b) refers to Pneumatophores, or “breathing roots,” which are essential because the waterlogged soil is anaerobic (lacks oxygen). Option (d) refers to salt exclusion, a mechanism used by certain species to prevent salt from entering their vascular system at the root level. Together, these traits allow mangroves to function as a natural bio-shield, protecting coastlines from storm surges and tsunamis. Their role in Blue Carbon sequestration further highlights their ecological importance.
