- The new Consumer Price Index (CPI) series uses 2024 as its base year, with weights derived from the Household Consumption Expenditure Survey (HCES) 2023-24.
- The Wholesale Price Index (WPI) is published by the Ministry of Statistics and Programme Implementation (MoSPI).
- The newly introduced Producer Price Index (PPI) is designed to eventually replace the WPI as India's principal non-retail inflation gauge.
Statements 1 and 3 are correct — the new CPI series adopts 2024 as its base year with weights drawn from the HCES 2023-24, and the newly introduced Output PPI is intended to eventually replace the WPI as India's principal non-retail inflation gauge and GDP deflator. Statement 2 is incorrect — the WPI is published by DPIIT (Ministry of Commerce and Industry), not MoSPI; MoSPI publishes GDP/GVA, IIP, and CPI but not WPI or PPI. This is a classic institution-conflation trap that exploits the tendency to club all statistical indices under a single publishing body.
- Bogibeel Bridge — Assam
- Noney Bridge — Manipur
- Sela Tunnel — Sikkim
- Dhola-Sadiya Setu — Assam–Arunachal Pradesh
Pairs 1, 2, and 4 are correctly matched — the Bogibeel Bridge (India's longest combined rail-cum-road bridge) spans the Brahmaputra in Assam; the Noney Bridge (world's tallest railway pier bridge at 141 m) lies on the Jiribam–Imphal line in Manipur; and the Dhola-Sadiya/Bhupen Hazarika Setu connects northern Assam to eastern Arunachal Pradesh. Pair 3 is incorrect — the Sela Tunnel is located in Arunachal Pradesh, not Sikkim; the correct state (Arunachal Pradesh) has been swapped for another prominent North-Eastern state, testing whether the candidate anchors on the specific fact rather than the general region.
Option (b) is correct — of the 58 total Parties to the Antarctic Treaty, only 29 hold Consultative (voting) status based on demonstrated substantial scientific research activity. Option (a) is incorrect — the Treaty was signed on 1 December 1959 but entered into force only on 23 June 1961, a classic temporal conflation trap. Option (c) is incorrect — the Madrid Protocol (1991) imposes an outright ban on all commercial mineral extraction with no clearance-based exception, not a conditional one. Option (d) is incorrect — Article IV merely freezes territorial claims, neither recognising, disputing, nor extinguishing them.
- Supreme Court judgment in Anuradha Bhasin v. Union of India
- Supreme Court judgment in Shreya Singhal v. Union of India
- Delhi High Court judgment in Telegram FZ LLC v. Union of India
- NEET-UG 2026 re-examination
The correct sequence is: Shreya Singhal v. Union of India (2015) → Anuradha Bhasin v. Union of India (2020) → Delhi HC's Telegram judgment (19 June 2026) → NEET-UG 2026 re-examination (21 June 2026). Option (c) inverts the final two events, placing the re-examination before the judgment that upheld the platform restriction enabling it — a trap exploiting the ease of transposing events only two days apart. Option (d) additionally swaps the order of the two landmark Supreme Court judgments, testing whether candidates anchor on the correct causal and chronological chain.
- It is the third confirmed interstellar object detected, after 1I/'Oumuamua and 2I/Borisov.
- Its estimated age of 10–12 billion years was determined primarily through analysis of its carbon-13 to carbon-12 isotope ratio using the James Webb Space Telescope.
- The comet's water was found to contain a lower proportion of deuterium than typical Solar System comets, indicating a warmer formation environment.
Statements 1 and 2 are correct — 3I/ATLAS is the third confirmed interstellar object after 1I/'Oumuamua (2017) and 2I/Borisov (2019), and its estimated age of 10–12 billion years was determined through JWST's NIRSpec instrument measuring the carbon-13/carbon-12 isotope ratio. Statement 3 is incorrect and a directional inversion trap — the comet's water actually contains roughly 30 times more deuterium than typical Solar System comets, pointing to a colder, heavily irradiated formation environment rather than a warmer one as stated.
