Current Affairs Quiz 04 July 2026

Statements 2 and 3 are correct — GAGAN is the world's first SBAS certified for the equatorial region (a technically demanding environment due to greater ionospheric disturbance), and its payloads are carried by GSAT-8, GSAT-10 and GSAT-15. Statement 1 is incorrect: GAGAN is not an independent positioning constellation like GPS or NavIC; it is a correction and augmentation layer that improves the accuracy and integrity of existing GPS signals — confusing an augmentation system with an independent constellation is the classic trap. Statement 4 is the exact reverse of the truth: LPV approaches require no expensive ground infrastructure, which is precisely why they extend precision landings to smaller regional airports — that cost drawback belongs to ILS, not to GAGAN-enabled LPV.

General Dhiraj Seth previously served as Vice Chief of the Army Staff and as GOC-in-C of both the Southern Command and South Western Command, making him one of the few officers to have commanded two operational Army commands along the western front. Options (a) and (d) name real commands — Northern Command and Andaman & Nicobar Command — but neither was held by General Seth. Option (c) attributes Eastern and Central Commands to his career, a role-swap that tests careful recall of the specific commands rather than vague familiarity with "some command he held."

Statements 1 and 3 are correct — under the Drugs (Eighth Amendment) Rules, 2026, xenografts (e.g., animal-tissue-derived heart valves) and gene therapeutic products (including gene replacement and gene-editing treatments) are among the categories newly added to CLAA licensing. Statement 2 is incorrect: vaccines were already covered under CLAA before this amendment, alongside large-volume parenterals and r-DNA-based medicines — the statement wrongly places a pre-existing category into the "newly added" bucket, a classic before/after temporal-confusion trap.

The correct match is A-3, B-4, C-2, D-1: Kaziranga has the highest tiger density in India at 13.44 per 100 sq. km (2022 AITE); Nameri's population quadrupled from 3 tigers (2022) to 12 (2025); Sonai-Rupai Wildlife Sanctuary is Nameri's satellite core where tigers returned after over two decades of local extinction; and Pakke Tiger Reserve in Arunachal Pradesh is contiguous with Nameri. Option (c) swaps facts 2 and 4 between Nameri and Sonai-Rupai (confusing the main reserve with its satellite core); option (b) swaps the density and population-growth facts between Kaziranga and Nameri; and option (d) swaps Kaziranga's density record with Pakke's contiguity fact.

The correct sequence is 2-1-3-4: Z25 was radio-tagged and released at Tadoba-Andhari Tiger Reserve on 22 December 2025 (2); within one to two weeks it flew to Kalaburagi, Karnataka, where it was captured by the Karnataka Forest Department (1); it was then relocated to Mudumalai Tiger Reserve in Tamil Nadu for better acclimatisation (3); and was ultimately found electrocuted on a transmission line in the Nilgiris (4). Option (b) is logically impossible — it places the Kalaburagi capture before the tagging event itself, which the bird had to undergo first. Option (c) places relocation to Mudumalai before the Kalaburagi capture, reversing the true sequence. Option (d) swaps the final two events, placing electrocution before relocation to Mudumalai.
