UPSC Editorials Quiz : 8 May 2026

Solution: C

• Digital Rails 2.0 is a conceptual centerpiece of the DPI@2047 Roadmap. Unlike the first generation of Digital Public Infrastructure (DPI 1.0), which focused on identity (Aadhaar) and simple transactions (UPI), Digital Rails 2.0 is designed to drive non-linear growth.
• Option (c) is the correct description because these rails are intended to move beyond basic welfare and into the realms of productivity and opportunity. This includes specialized digital frameworks for MSMEs to access global markets, job discovery platforms for local talent, and asset tokenization to unlock credit.

The goal is to build a “comprehensive system” that enables broad-based prosperity. By using tools like AI-driven personalized guidance and cross-sectoral strategic unlocks, Digital Rails 2.0 aims to ensure that digital inclusion translates directly into economic output, potentially contributing up to 4% of India’s GDP by the end of the decade.

Solution: A

Statement-I is correct. Internationalizing the Indian Rupee through bilateral trade settlement arrangements can contribute to exchange-rate stability by reducing India’s dependence on foreign currencies—especially the US dollar—for external trade. When a greater share of trade is settled in rupees, demand for foreign currency declines, thereby reducing pressure on the rupee during periods of global financial uncertainty. Over time, this can complement and sometimes reduce the need for frequent RBI forex interventions.

Statement-II is also correct. If imports are paid for in rupees:

• the immediate outflow of foreign exchange reserves declines,
• importers are less exposed to fluctuations in dollar exchange rates,
• external vulnerability reduces during global currency shocks.

Statement-II correctly explains Statement-I because these mechanisms collectively reduce demand for foreign currency and help cushion volatility in the exchange market, thereby supporting rupee stability.

Solution: A

• Statement-I is correct. The Baltic Sea is highly vulnerable to pollutants. There are thousands of shipwrecks, such as the Franken, which still contain large volumes of oil. Additionally, World War II munitions release toxic chemicals like TNT and mercury as they corrode. These substances enter the marine food chain and persist for long periods.
• Statement-II is correct. The Baltic is a shallow, semi-enclosed sea. Its only exit is through narrow and shallow straits. This geography restricts the inflow of oxygen-rich saline water and the outflow of polluted brackish water. Consequently, it takes approximately three decades for the water to be fully exchanged.
• Statement-II provides the correct explanation for Statement-I. The high susceptibility to long-term damage mentioned in Statement-I is a direct consequence of the slow water renewal described in Statement-II. Because the water does not flush out into the ocean quickly, any oil spill or chemical leak remains “trapped” within the Baltic ecosystem for decades, leading to bioaccumulation in fish and shellfish and long-lasting ecological degradation.

Solution: B

• The term “windfall” refers to an unexpected gain that “falls” into one’s lap, like fruit blown down by the wind.
• In economics, Statement (b) is correct as it refers to profits that are not earned through innovation or efficiency but through external luck—such as a war driving up oil prices. Governments impose this tax to capture a portion of these “excess” profits for public welfare. It is based on the principle that natural resources are national assets and their exploitation during global crises should benefit the state, especially when the state has to bear the burden of rising subsidy bills elsewhere.
• Options (a), (c), and (d) refer to capital gains tax, green/carbon tax, and import duties respectively, which are structurally different from the opportunistic and temporary nature of a windfall levy.

Solution: C

• Statement 1 is correct. Ground-level ozone is not emitted directly; it is a secondary pollutant formed by the photochemical reaction of precursor gases like NOx and VOCs.
• Statement 2 is correct. While particulate matter (PM) often peaks in winter due to stagnant conditions, ozone requires strong solar rays to form. Data from the Central Pollution Control Board since 2015 confirms that ozone concentrations in Delhi are highest in May.
