Relevance: OPEC is a major intergovernmental organization influencing global crude oil prices, directly impacting India’s energy security and import bill. Questions often test factual clarity on member countries, headquarters (Vienna), and distinctions between OPEC and OPEC+.

Explanation

— The Organization of Petroleum Exporting Countries (OPEC) is a permanent intergovernmental organization of oil-exporting developing countries that coordinates and unites their respective petroleum policies.

— OPEC tries to stabilise oil prices in international oil markets in order to eliminate damaging and unnecessary swings, while always keeping in mind the interests of oil-producing nations and the importance of ensuring a consistent income for them.

— OPEC was founded on September 14, 1960, following a meeting in the Iraqi capital of Baghdad attended by the Organization’s five founding members: Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela.

Relevance: Area 51 often features in discussions on advanced defence technologies, secrecy, and strategic military research, which are relevant for internal security and science & technology segments of the syllabus. Such topics help in understanding global security dynamics and the role of technological superiority in geopolitics.

Explanation

— The name Area 51 instantly conjures images of flying saucers, hidden autopsies and little green beings. As per official records, Area 51 is a highly classified US military testing facility in Nevada, US. But decades of secrecy have helped transform it into the planet’s most enduring ‘alien’ legend.

Relevance: Great Nicobar lies near the Malacca Strait, a critical global maritime chokepoint, making it strategically important for India’s Indo-Pacific policy.

Explanation

— The National Green Tribunal (NGT) Monday cleared the way for the government’s Rs 81,000-crore Great Nicobar mega infrastructure project, noting its “strategic importance” and observing that there were “adequate safeguards” in the project’s environmental clearance.

The above-mentioned statements refer to:

— Indian evolution in cutting edge sectors such as information technology, artificial intelligence, biotechnology and space exploration… creates a lot of cooperation opportunities with Brazil.

— Brazil is India’s largest trade partner in Latin America. The countries have agreed last year to increase our trade flow to $20 billion by 2030 in 2025, bilateral flow surpassed $15 billion for the first time in history, a growth of 25% in relation to 2024.

Therefore, option (c) is the correct answer.

QUESTION 5

The ‘Emission Gap Report’ is published by:

(a) United Nations Environment Programme

(b) Intergovernmental Panel on Climate Change

(c) International Energy Agency

(d) World Meteorological Organisation

Story continues below this ad

Relevance: The Emissions Gap Report is directly linked to global climate commitments under the United Nations Framework Convention on Climate Change and the Paris Agreement. UPSC often tests knowledge of who publishes key global reports, making such questions scoring and elimination-friendly.

Explanation

— The UNEP Emissions Gap Report 2025, headlined “Off Target,” warns that existing climate commitments are insufficient to reach the Paris Agreement’s goals, with the globe on course to warm by 2.3-2.5°C this century. Global emissions reached a new high in 2024, and to stay below 1.5°C by 2030, emissions must be reduced by 26%.

— The Emissions Gap Report 2025 indicated that even if countries keep their climate pledges, the world will rise by 2.3 to 2.5°C by the end of the century, causing huge damage.

Therefore, option (a) is the correct answer.
