5 October 2026 • Static + Current Affairs • Answers & Explanations
2. Desert National Park is located in Rajasthan.
3. India's Bustard Recovery Programme involves the Wildlife Institute of India and Rajasthan Forest Department.
4. The captive-breeding programme is intended only for permanent ex-situ conservation and not for eventual release into natural habitat.
The conservation programme is now moving from development of a viable conservation-breeding population towards carefully managed rewilding. Two captive-bred male GIBs were released into the wild at Desert National Park on 4 October 2026.
UPSC Trap: Ex-situ breeding can support in-situ recovery; the two are not mutually exclusive. Official Source: PIB – Great Indian Bustard Rewilding2. It seeks to expand access to high-performance computing infrastructure.
3. Applications include weather prediction, climate modelling, computational biology and astrophysics.
4. The Mission depends entirely on imported servers, software, cooling and networking technologies.
The National Supercomputing Mission has also contributed to indigenous development of servers, software, cooling and networking technologies. By September 2026, 40 supercomputers under the ecosystem delivered about 68 petaflops.
UPSC Trap: Strategic computing capability is not based exclusively on imported technology. Official Source: PIB – India's Rising Supercomputing Ecosystem2. An Ordinance has the same force and effect as an Act of Parliament while it remains in operation.
3. An Ordinance can amend the Constitution under Article 368.
4. An Ordinance must be laid before Parliament after reassembly.
The ordinance power is a legislative power for temporary law-making. An Ordinance cannot be used as a substitute for the constitutional amendment procedure.
2. Prior recommendation of the President is required for its introduction.
3. Rajya Sabha can reject a Money Bill permanently.
4. The Speaker of the Lok Sabha certifies whether a Bill is a Money Bill.
Rajya Sabha can recommend amendments but cannot reject or amend a Money Bill in the same manner as an ordinary Bill.
Lok Sabha enjoys a special constitutional position in respect of Money Bills.2. It is calculated using nominal GDP and real GDP.
3. Its basket and weights are necessarily identical to those of the Consumer Price Index.
4. An increase in the GDP deflator can indicate an increase in the general price level of domestic output.
The GDP deflator is broader than a fixed consumer basket because it covers domestically produced final output represented in GDP.
2. Government borrowing
3. Proceeds from disinvestment
4. Corporation tax
Corporation tax is a revenue receipt. Borrowing, recovery of loans and disinvestment affect assets or liabilities and are classified as capital receipts.
2. Son — Ganga
3. Indravati — Godavari
4. Tungabhadra — Kaveri
Tungabhadra is a major tributary of the Krishna River, not the Kaveri.
2. It can suppress vertical mixing near the surface.
3. It may contribute to accumulation of pollutants close to the ground.
4. It invariably produces heavy rainfall.
An inversion creates a stable atmospheric layer that can trap pollutants. It does not inherently or invariably cause rainfall.
2. They may help maintain gene flow between otherwise isolated populations.
3. A wildlife corridor must necessarily be a legally notified National Park.
4. Infrastructure fragmentation can reduce the functional effectiveness of corridors.
Wildlife corridors are landscape linkages. Their ecological function does not depend on every part of the corridor being designated as a National Park.
2. Decomposition of excessive biomass can lower dissolved oxygen levels.
3. Agricultural runoff can contribute nutrients to lakes and rivers.
4. Eutrophication necessarily increases dissolved oxygen at all depths.
Nutrient enrichment can eventually produce hypoxic or oxygen-depleted conditions, especially when abundant organic matter decomposes.
2. Guide RNA can help direct the editing machinery to a selected genetic sequence.
3. CRISPR-based editing is limited exclusively to bacteria and cannot be used in plants or animals.
4. Gene editing raises biosafety and ethical questions in some applications.
CRISPR systems originated as microbial defence mechanisms, but gene-editing applications now extend to plants, animals and human cells.
2. Anekantavada is associated with Jain philosophical thought.
3. Buddhism and Jainism both accepted the Vedas as supreme and infallible authority.
4. Both traditions questioned aspects of ritual-centred orthodox Brahmanism.
Both Buddhism and Jainism are generally classified among heterodox traditions because they did not accept Vedic authority in the orthodox sense.
2. Ahmedabad Mill Strike — Textile workers
3. Kheda Satyagraha — Peasant revenue relief
4. Bardoli Satyagraha — Jawaharlal Nehru as principal leader
Bardoli Satyagraha of 1928 was led prominently by Vallabhbhai Patel, who subsequently came to be widely known as “Sardar”.
2. The principle of Most-Favoured-Nation treatment generally seeks non-discrimination among trading partners.
3. The WTO can directly impose domestic taxes on citizens of member countries.
4. Trade in services is covered within the WTO framework.
The WTO establishes and administers international trade rules; it does not possess a sovereign power to directly tax citizens of member countries.
2. Maintaining soil cover can help reduce erosion and moisture loss.
3. Crop diversification or rotation can form part of conservation agriculture.
4. It necessarily requires complete removal of all crop residues from agricultural fields.
Conservation agriculture commonly emphasises minimal soil disturbance, permanent or substantial soil cover and crop diversification. Crop residues may therefore be useful rather than necessarily removed.
