Mauritius-based investment firm Soach Global founder moots demat holding of foodgrains ↗

Consider the following statements regarding warehouse-receipt or demat-based commodity instruments and exchange-based price discovery for agricultural produce in India:Answer ▾
  1. Dematerialised commodity instruments issued against agricultural produce can be held in demat accounts and traded on commodity exchanges, enabling price discovery for farmers before physical delivery takes place.
  2. The Minimum Support Price (MSP) announced by the Government for notified crops legally binds commodity exchanges to use it as the floor price for all futures and spot trading in those crops.
  3. Farmer Producer Companies (FPCs) and cooperative societies are recognised forms of farmer collectives that can aggregate produce and participate in commodity market operations.

Which of the statements given above is/are correct?

Correct

Incorrect. The answer is C

Explanation

Statement 1 is correct. The concept of dematerialised commodity instruments — analogous to warehouse receipts in demat form — is well-established in India's commodity market framework. Such instruments can be held in demat accounts via depositories (NSDL/CDSL) and traded on recognised commodity exchanges such as NCDEX or MCX, enabling forward price discovery for farmers even before the physical produce changes hands. This is the core mechanism underlying electronic negotiable warehouse receipts (eNWRs) and similar instruments. Statement 2 is incorrect. The Minimum Support Price is an administrative price guarantee announced by the Cabinet Committee on Economic Affairs (CCEA) on the recommendation of the Commission for Agricultural Costs and Prices (CACP). It is not a statutory floor that legally binds commodity exchanges. Exchanges are regulated by SEBI and set prices through market-driven demand and supply. MSP is a procurement benchmark for government agencies (chiefly FCI and state agencies), not a mandated exchange floor. No legislation currently makes MSP legally enforceable on private trade or exchanges. Statement 3 is correct. Farmer Producer Companies (FPCs) are recognised under the Companies Act and the amended Companies Act provisions, while cooperative societies are governed by state cooperative legislation and the Multi-State Co-operative Societies Act at the central level. Both are established institutional forms through which farmers can collectively aggregate produce, access credit, and participate in commodity markets — including commodity exchange platforms and warehousing systems.

Distribution of taxing powers · GS-II

Can states levy a tax on sales tax? The 30-year-old legal question SC has now settled, explained ↗

Consider the following pairs regarding legislative entries under the Seventh Schedule of the Constitution of India and their scope:Answer ▾
  1. Entry 54, State List — Empowers states to tax the sale or purchase of goods (now narrowed to specified goods after the 101st Constitutional Amendment)
  2. Entry 82, Union List — Empowers Parliament to levy taxes on income other than agricultural income
  3. Entry 92A, Union List — Empowers Parliament to levy taxes on the sale or purchase of goods in the course of inter-state trade or commerce

Which of the pairs given above is/are correctly matched?

Correct

Incorrect. The answer is C

Explanation

All three pairs are correctly matched. Entry 54 of the State List vests in state legislatures the power to tax sale or purchase of goods; this broad power was significantly narrowed by the 101st Constitutional Amendment (2016), which introduced GST and restricted Entry 54 to only specified goods (such as petroleum crude, high-speed diesel, petrol, natural gas, aviation turbine fuel, and alcoholic liquor for human consumption). Entry 82 of the Union List gives Parliament the exclusive power to tax income other than agricultural income — the distinction between agricultural and non-agricultural income being a classic constitutional allocation of taxing competence. Entry 92A, inserted by the 46th Constitutional Amendment (1982), gives Parliament the power to tax sale or purchase of goods in the course of inter-state trade or commerce, which is the constitutional foundation for the Central Sales Tax Act — a power distinct from the states' intra-state sales tax power under Entry 54. Understanding how the GST reform (101st Amendment) restructured Entry 54 is directly relevant because surcharge disputes over old sales tax laws, as settled by the Supreme Court's recent Constitution Bench, have little prospective significance precisely because Entry 54's breadth has been curtailed.

Organic waste can be converted into protein-rich fish feed: ICAR official ↗

Consider the following statements regarding fishmeal dependence, feed cost structure, and alternative protein ingredients in India's aquaculture sector:Answer ▾
  1. Fishmeal, derived from wild-caught fish, remains a critical conventional protein ingredient in aquaculture feed, and its limited availability and rising prices are a major driver of increasing production costs in India's aquaculture sector.
  2. Black Soldier Fly (BSF) larvae-based feed technology is relevant to aquaculture primarily because BSF larvae can fix atmospheric nitrogen and thereby enrich organic waste with protein, making it nutritionally equivalent to fishmeal.
  3. Developing alternative protein ingredients for fish feed from locally available resources such as insects, microalgae, seaweeds, and agro-processing residues is considered a strategy to reduce India's aquaculture sector's dependence on wild fish stocks.

Which of the statements given above is/are correct?

Correct

Incorrect. The answer is A

Explanation

Statement 1 is correct. Fishmeal — produced by processing wild-caught marine fish — has long been the dominant high-protein ingredient in aquaculture feed globally and in India. Its supply is constrained by finite wild fish stocks, and its price volatility directly raises aquaculture production costs, a well-documented challenge in fisheries economics. Statement 2 is incorrect. BSF larvae do not fix atmospheric nitrogen. Their value in feed production comes from their biological ability to bioconvert biodegradable organic waste — market waste, food scraps, agricultural residues — into protein-rich and lipid-rich biomass through consumption and digestion. This is a heterotrophic bioconversion process, not nitrogen fixation (which is a trait of certain bacteria and legume-associated microorganisms). The statement conflates two entirely different biological mechanisms. Statement 3 is correct. A core principle of sustainable aquaculture economics is diversifying the protein ingredient base away from fishmeal toward locally sourced alternatives — insects (including BSF), microalgae, seaweeds, aquatic plants, and agro-processing by-products. This reduces pressure on wild fish stocks harvested for reduction (fishmeal production), lowers feed cost volatility, and aligns with circular bio-economy principles. ICAR-CMFRI's research mandate explicitly encompasses this feed-ingredient diversification strategy.

Drug regulation and approval · GS-II

FDA adds rare vision-loss warning to popular obesity, diabetes drugs ↗

Consider the following pairs regarding post-marketing drug safety surveillance mechanisms:Answer ▾
  1. Pharmacovigilance — Systematic monitoring of adverse effects of approved drugs after they are released into the market
  2. Label revision (Warning update) — A regulatory action taken before a drug is approved for marketing, based on clinical trial data
  3. Adverse Event Reporting System — A passive surveillance tool through which patients, healthcare providers, and manufacturers report unexpected drug reactions post-approval

Which of the pairs given above is/are correctly matched?

Correct

Incorrect. The answer is B

Explanation

Pharmacovigilance refers to the science and activities relating to the detection, assessment, understanding, and prevention of adverse effects of medicines after they have been approved and are in widespread use — so Pair 1 is correctly matched. A label revision or warning update is a post-marketing regulatory action, not a pre-approval one — it is triggered when post-approval surveillance (such as analysis of adverse event reports and published clinical data) reveals new safety signals. Pair 2 incorrectly describes it as a pre-approval action, making it wrongly matched. An Adverse Event Reporting System (such as the US FDA's FAERS, or India's CDSCO's PvPI portal) is indeed a passive, voluntary/mandatory post-marketing reporting mechanism through which unexpected drug reactions are communicated to regulators — so Pair 3 is correctly matched. This is precisely the mechanism the FDA used in the GLP-1 drug case: it reviewed both published trial data and its electronic adverse event reporting system before updating the drug label.

Heat-trapping carbon pollution drops, but scientists cite Iran war rather than energy progress ↗

Consider the following statements regarding global carbon dioxide emissions accounting and the framework under which they are reported at UN climate negotiations:Answer ▾
  1. Under the global carbon budget framework, total CO2 emissions are tracked from two principal sources: fossil-fuel combustion and land-use change (such as deforestation), and a decline in one source can be offset by a rise in the other.
  2. The Paris Agreement (2015) replaced the Kyoto Protocol's approach of binding mitigation targets imposed exclusively on developed (Annex I) countries with a bottom-up system of Nationally Determined Contributions applicable to all Parties.
  3. A temporary, crisis-driven fall in fossil-fuel emissions — such as one caused by an oil-supply shock — is considered equivalent, within the UNFCCC reporting framework, to a structural peak in emissions driven by a systemic shift to renewable energy.

Which of the statements given above is/are correct?

Correct

Incorrect. The answer is D

Explanation

Statement 1 is correct: the global carbon budget, as published by bodies like the Global Carbon Project and reported at COP negotiations, distinguishes between two broad emission sources — fossil-fuel combustion (coal, oil, gas) and land-use change (deforestation, peat fires, etc.). A drop in one category does not automatically reduce total emissions if the other category rises simultaneously; this is precisely what makes the overall global CO2 trajectory different from the fossil-fuel-only figure. Statement 2 is correct: the Kyoto Protocol (1997) imposed legally binding quantified emission-reduction targets on Annex I Parties (developed nations and economies in transition) only, through mechanisms like the Clean Development Mechanism and Emissions Trading. The Paris Agreement (2015) fundamentally changed this architecture by introducing Nationally Determined Contributions — nationally self-defined pledges — from all Parties, including developing countries such as India and China, making it a bottom-up, universally applicable instrument. Statement 3 is incorrect as a matter of emissions-accounting principle. The UNFCCC/Paris Agreement framework and the Global Carbon Project's methodology track the magnitude and trend of emissions regardless of their cause; a crisis-induced fall (caused by war, recession, or pandemic) and a structural decline driven by an energy transition are both captured in the same accounting ledger. However, scientists and policymakers treat them as categorically different: a crisis shock typically produces a sharp, V-shaped fall followed by a rebound (as seen in 2009 and 2020), whereas a genuine peak represents a durable turning point. The framework does not treat the two as equivalent — identifying whether an emission peak is structural or transitory is central to assessing progress under NDCs.
