UPSC Current Affairs Quiz : 7 April 2026

Solution: B

• Stagflation is a unique economic condition where low economic growth (stagnation) coexists with high inflation and high unemployment.
• Statement 1 is correct because, in a typical economy (as described by the Phillips Curve), inflation and unemployment have an inverse relationship; however, during stagflation, both rise together.
• Statement 2 is correct as stagflation is primarily driven by negative supply shocks (like the 2026 energy crisis). When the aggregate supply curve shifts to the left, it results in a higher price equilibrium and a lower quantity of output, effectively causing “cost-push” inflation while the economy shrinks.
• Statement 3 is incorrect because traditional tools are ineffective. If a central bank uses monetary expansion to fight stagnation, it risks further fuelling inflation. Conversely, if it raises interest rates to curb inflation, it may worsen the recession. Therefore, supply-side reforms and energy diversification are preferred over simple demand-side stimulus.

Solution: B

• Tar balls are persistent remnants of oil spills or natural seeps.
• Statement 1 is correct because their formation is a result of weathering, which involves physical and chemical changes like evaporation, emulsification, and photo-oxidation. As the lighter, more volatile fractions of oil leave, the remaining residue becomes denser and stickier.
• Statement 2 is incorrect; in India, tar balls are most prominent on the Western Coast (from Gujarat to Goa) between April and September. This is due to the south-westerly winds and sea currents during the monsoon season that push floating debris toward the shore.
• Statement 3 is correct as tar balls are complex mixtures. They contain heavy hydrocarbons (paraffins and aromatics) and asphaltenes, which provide their dark color. The presence of trace metals like nickel and vanadium often helps researchers trace the tar ball back to its specific source of crude oil. They also frequently trap sand and microplastics, increasing their density.

Solution: C

• The Indian Crested Porcupine is an adaptable Old World rodent.
• Statement 1 is correct as it is the largest rodent in India, weighing up to 18 kg, and exhibits nocturnal behavior, which allows it to forage safely and makes it a difficult agricultural pest to monitor.
• Statement 2 is incorrect; the species is currently listed as ‘Least Concern’ (LC) on the IUCN Red List because it has a very wide geographic range across Southern Asia and the Middle East and is highly adaptable to different environments, including scrublands and cultivated areas.
• Statement 3 is correct. The porcupine has a high survival rate in regions where its natural predators, such as leopards, are declining. Without these apex predators to check their population, porcupines can become agricultural pests, as seen in the Pampore highlands, where they damage high-value crops like saffron by devouring the underground corms.

Solution: B

• Saffron (Crocus sativus) cultivation is highly specialized.
• Statement 1 is correct; unlike many crops, saffron is not grown from seeds but from corms, which are thick, underground storage organs. These corms are perennial, meaning they live for multiple years.
• Statement 2 is correct as the Pampore highlands are famous for Karewa soil. Geologically, Karewas are lacustrine (lake-derived) deposits consisting of sand, silt, and clay, which provide the excellent drainage and mineral content necessary for saffron.
• Statement 3 is incorrect because while Safranal provides the characteristic aroma, it is Crocin that is responsible for the intense color. Another compound, Picrocrocin, gives saffron its bitter taste. Given that it takes nearly 175,000 flowers to produce just one kilogram of the spice, it remains the most expensive by weight globally. The GI tag for Kashmir Saffron ensures its protection against cheaper substitutes.

Solution: A

• The United Arab Emirates (UAE) is a federation located in the southeast of the Arabian Peninsula.
• Statement 1 is correct as over 80% of its land is part of the Rub’ al Khali, the world’s largest contiguous sand desert.
• Statement 2 is correct; the Al Hajar Mountains run through the east, separating the coastal plains from the desert.
• Statement 4 is correct, as the western regions of Abu Dhabi are known for Sabkhas (salt flats) formed by seawater evaporation.

Statement 3 is incorrect; the UAE has coastlines along the Persian Gulf to the north and the Gulf of Oman to the east. It does not border the Red Sea, which is located to the west of Saudi Arabia. Its proximity to the Strait of Hormuz (a critical chokepoint for oil) makes its maritime security vital for global energy stability, particularly during the 2026 regional crisis.

Solution: D

• Emulsification (1) is the process where heavy oil residue mixes with seawater, creating a “mousse” that eventually fragments into spheres (Statement B).
• Photo-oxidation involves the chemical change of oil when exposed to sunlight, contributing to weathering, but wave action specifically describes the physical fragmentation (A) of the oil slick into smaller blobs.
• Asphaltenes (3) are a key chemical component of tar balls; they are dense, dark, and highly resistant to degradation, giving the blobs their characteristic black color and tackiness (C).
• Tar Balls Management Rules, 2026 aim to mitigate the impact of oil spills on marine ecosystems and the tourism industry, particularly in states like Goa.

Solution: D

• Founded in 1935, the All India Depressed Classes League was a pivotal organization in the life of Babu Jagjivan Ram. Its core objective was to fight against the social scourge of untouchability and ensure that the struggle for Indian independence was inextricably linked with the struggle for social equality.

Jagjivan Ram believed that political freedom from the British would be hollow without the social emancipation of the Dalits. He acted as a bridge between the Dalit community and the Congress party, ensuring their voices were heard in the national discourse. This work laid the foundation for his later roles as Labour Minister and Deputy Prime Minister, where he continued to push for landmark legislations like the Minimum Wages Act to uplift the marginalized sections of society.

Solution: D

• The National Chambal Sanctuary is a multi-species protected area. It is world-renowned for the Gharial, but also protects the Red-crowned roofed turtle and the smooth-coated otter.
• Statement 3 is incorrect. Far from having no turtles, the Chambal is home to eight species of freshwater turtles. The river’s varied morphology, including both steep gradients and deep, calm pools, provides diverse niches for these species.

Solution: A

• The Gruh Sugam Portal is a niche digital intervention in the economy sector.
• Statement 1 is correct; the National Housing Bank (NHB), as the apex regulator, spearheaded this project to improve affordable home ownership for Defense, Paramilitary, and Government personnel. It acts as a unified digital marketplace where lenders compete for the borrower’s business.
• Statement 2 is correct; to ensure high processing efficiency and security, the portal features a dedicated grievance redressal mechanism and an online chat facility. This is vital for consumer protection, especially for personnel who may be operating in high-stress environments and need quick resolutions to financial queries.
• Statement 3 is incorrect. The portal does not “replace” administrative units; instead, it integrates with them. Personnel apply through their office’s digital interface, meaning the administrative unit becomes a facilitator in the digital journey. This synergy allows for minimal data entry and faster disbursement because the employment and eligibility verification can be streamlined digitally. The significance lies in providing “banking at the doorstep” for soldiers in border areas, ensuring their families are supported while they are on duty.

Solution: A

• Statement 1 is correct: Natural Mineral Water must originate from protected underground aquifers or natural springs. To preserve its “virgin” state and prevent contamination, it must be bottled at the source.
• Statement 2 is incorrect: This is the defining difference between “Packaged Drinking Water” and “Natural Mineral Water.” While packaged water can be treated via RO and then artificially mineralized, Natural Mineral Water must remain in its original chemical state. Any process that alters its natural mineral composition is prohibited.
• Statement 3 is correct: Producers are strictly forbidden from using chemical disinfectants like chlorine. They are only allowed physical treatments like filtration, aeration, or UV light to ensure the water is microbiologically wholesome. The mineral “fingerprint” (calcium, magnesium, bicarbonates, etc.) depends on the specific geological layers the water percolates through over decades. This makes Natural Mineral Water a unique product of its geography, often providing highly bioavailable minerals that support bone and cardiovascular health.
