GK One-Liners

What: 14 April 2026 marks the 135th birth anniversary of Dr. Bhimrao Ramji Ambedkar, born on 14 April 1891 at Mhow, Madhya Pradesh (now renamed Dr. Ambedkar Nagar). He was the principal architect of the Indian Constitution and was awarded the Bharat Ratna posthumously in 1990.

How: As Chairman of the Drafting Committee of the Constituent Assembly (1946–1949), Ambedkar steered the drafting of the Constitution adopted on 26 November 1949. He was the chief proponent of Article 17 (Abolition of Untouchability) and Article 15 (Prohibition of Discrimination on grounds of religion, race, caste, sex, or place of birth). His landmark writings include Annihilation of Caste (1936) and The Buddha and His Dhamma (1957).

Why: Ambedkar-linked facts are perennial UPSC GS-I (Modern History) and GS-II (Polity) questions. Key MCQ anchors: birth year (1891), birthplace (Mhow/MP), Bharat Ratna year (1990 — posthumous), Article 17 vs Article 15, Drafting Committee role. Watch for swap traps between Article 17 and Article 14.

What: The Amaravati Quantum Reference Facility (AQRF) was inaugurated at Amaravati, Andhra Pradesh on World Quantum Day (14 April 2026) — making it India’s first Quantum Test Reference Facility. It was inaugurated by Chief Minister N. Chandrababu Naidu. The facility comprises two testbeds: Amaravati 1S (at SRM University) and Amaravati 1Q (at Medha Towers, Gannavaram), both developed indigenously by Qubitech.

How: AQRF operates under the twin umbrellas of Amaravati Quantum Valley and the National Quantum Mission (NQM). NQM, approved in 2023, carries a budget of ₹6,003.65 crore for 2023–2031 under the Department of Science & Technology (DST). It anchors four technology hubs at IISc Bengaluru, IIT Delhi, IIT Madras, and IIT Bombay. QNu Labs has already demonstrated a 1,000-km Quantum Key Distribution (QKD) network; the NQM target is 2,000 km.

Why: World Quantum Day is observed on 14 April — the date ‘4.14’ references Planck’s constant (h ≈ 4.14 × 10⁻¹⁵ eV·s). This topic tests UPSC GS-III (Science & Technology) and Banking Awareness. Key anchors: NQM budget (₹6,003.65 cr), 4 IIT/IISc hubs, 2,000-km QKD target, “first in India” tag for AQRF.

What: Prime Minister Narendra Modi inaugurated the Delhi–Dehradun Economic Corridor on 14 April 2026 at Dehradun. The 213-km, 6-lane access-controlled expressway runs from Akshardham, Delhi to Dehradun and was built by NHAI (National Highways Authority of India) under MoRTH (Ministry of Road Transport and Highways) at a cost of ₹12,000–13,000 crore. Travel time between the two cities drops from 6.5 hours to approximately 2.5 hours.

How: The corridor passes through ecologically sensitive Shivalik forests via a 12-km elevated section — designated as Asia’s longest elevated wildlife corridor. The design includes 350+ animal underpasses to protect the Rajaji National Park buffer zone and reduce human-wildlife conflict. This approach integrates infrastructure development with habitat continuity.

Why: Combines two UPSC themes — GS-III Infrastructure (expressway length, cost, NHAI) and GS-III Environment (wildlife corridor, Rajaji National Park). Strong MCQ hooks: 213 km total length, 12 km elevated section (Asia record), 350+ underpasses, travel time reduction. Location trap: Akshardham is the Delhi starting point, not Noida or Meerut.

What: Exercise DUSTLIK is a bilateral joint military exercise between India and Uzbekistan. The 7th edition is being conducted from 12–25 April 2026 at Gurumsaray Field Training Area, Namangan, Uzbekistan. India is represented by personnel from the Mahar Regiment (Indian Army) along with Indian Air Force (IAF) contingents — 60 personnel from each side.

How: The exercise focuses on counter-terrorism operations in mountainous terrain, joint tactical drills, humanitarian assistance, and inter-operability between the two armed forces. It alternates location between India and Uzbekistan; the 6th edition was held at Aundh, Pune (India).

Why: Bilateral defence exercises are a standard UPSC GS-II (International Relations) and CDS/NDA question area. Key MCQ anchors: 7th edition, Mahar Regiment, Namangan location, 12–25 April dates. Edition and location traps are classic distractors — note that the 6th edition was in India (Pune), not Uzbekistan.

What: Sanjay Khanna was appointed Chairman and Managing Director (CMD) of Bharat Petroleum Corporation Limited (BPCL) effective 9 April 2026, with tenure till 31 May 2029. BPCL is a Maharatna Public Sector Undertaking (PSU) under the Ministry of Petroleum and Natural Gas. Khanna brings 30+ years of refinery operations experience and holds a degree in Chemical Engineering from NIT Tiruchirappalli and a PG in Finance from the University of Mumbai.

How: Under this leadership, BPCL has announced a ₹75,000 crore capital expenditure plan over five years. The flagship project is the Bina Petrochemical and Refinery Expansion Project (BPREP) — a ₹50,000 crore investment in Madhya Pradesh. BPCL’s predecessor CMD was G. Krishnakumar, who retired on 30 April 2025. BPCL has set a net-zero carbon target for 2040.

Why: PSU CMD appointments are frequently tested in Banking (IBPS PO, RBI Grade B, SBI PO) and SSC exams. Key anchors: Maharatna status, Ministry of Petroleum and Natural Gas, ₹75,000 cr total capex, ₹50,000 cr BPREP (Madhya Pradesh), net-zero 2040 target. Swap trap: BPREP is in MP, not Maharashtra or Rajasthan.

What: The Kigali Amendment (2016) to the Montreal Protocol (1987) mandates a global phase-down of Hydrofluorocarbons (HFCs) — potent greenhouse gases used in refrigeration and air-conditioning. India ratified the Kigali Amendment in 2021. India’s phase-down schedule is: Freeze in 2028 → 10% reduction by 2032 → 20% by 2037 → 30% by 2042 → 85% by 2047. No new HFC clearances will be issued after 31 December 2027. Key HFCs in scope include HFC-134a, HFC-32, and HFC-125.

How: The transition involves replacing HFCs with low-Global Warming Potential (GWP) alternatives such as natural refrigerants (CO₂, ammonia) and newer HFO (Hydrofluoroolefin) blends. India’s compliance is monitored under the Ozone Cell, Ministry of Environment, Forest and Climate Change (MoEFCC). The Montreal Protocol’s success in phasing out ozone-depleting CFCs (Chlorofluorocarbons) provides the institutional model.

Why: This is a high-yield UPSC GS-III (Environment) and GS-II (International Treaties) topic. The multi-date schedule is a prime number-trap MCQ target: the freeze year is 2028 (not 2025 or 2030). Key linkages to test: Kigali (2016) amends Montreal Protocol (1987); India ratification year is 2021; 85% reduction target is 2047 — not 2050.
