[A] Ministry of Power
[B] Ministry of Petroleum and Natural Gas
[C] Ministry of New and Renewable Energy
[D] Ministry of Environment, Forest and Climate Change
[B] Ministry of Petroleum and Natural Gas
[C] Ministry of New and Renewable Energy

Notes:
India recently signed agreements to supply 4.12 lakh tonnes of green hydrogen derivatives to Japan and Singapore. The Green Hydrogen Certification Scheme of India (GHCI) was launched simultaneously to ensure credible and transparent green hydrogen production. GHCI is India’s first certification framework to verify that hydrogen is produced exclusively using renewable energy. This certification ensures hydrogen is recognized as “green.” GHCI was launched by the Ministry of New and Renewable Energy (MNRE). The Bureau of Energy Efficiency (BEE) is the nodal agency for GHCI. It is supported by the National Green Hydrogen Mission.

2. What type of disease is “Rabies” that was recently seen in news?
[A] Genetic disorder
[B] Zoonotic disease
[C] Fungal infection
[D] None of the Above
[B] Zoonotic disease
[C] Fungal infection
[D] None of the Above
Correct Answer: B [Zoonotic disease]
Notes:
A six-year-old girl in Kerala’s Malappuram district sadly died of rabies even after getting preventive vaccination, highlighting a serious public health concern. Rabies is a fatal zoonotic disease caused by the Rabies virus (RABV), which attacks the nervous system. Rabies virus is an RNA virus from the rhabdovirus family and spreads in two main ways in the body. It can directly enter the peripheral nervous system and reach the brain. Or it can first hide and multiply in muscle tissue, then move into the nervous system through neuromuscular junctions. Once in the brain, it causes severe and deadly inflammation.

4. What does the cosmological parameter S8 (Sigma Eight) primarily measure?
[A] The temperature of stars
[B] The “clumpiness” or clustering of matter in the universe
[C] The expansion rate of the universe
[D] None of the Above
[B] The “clumpiness” or clustering of matter in the universe
[C] The expansion rate of the universe
[D] None of the Above
Correct Answer: B [The “clumpiness” or clustering of matter in the universe]
Notes:
The Subaru Telescope in Hawaii recently used the Hyper Suprime-Cam to carry out a deep sky survey from the University of Tokyo. It reported a Sigma Eight (S8) value of 0.747, which matches earlier results from gravitational lensing studies. Sigma Eight (S8) is a key measure in cosmology that shows how matter is clustered or “clumpy” across the universe on a scale of 26 million light-years. It tells scientists how much visible and dark matter is gathered in different parts of space. This finding helps us understand how the universe evolved from a smooth early state after the Big Bang.

5. Natural hydrogen is formed through which geological process?
[A] Mass wasting
[B] Serpentinisation
[C] Liquefaction
[D] Carbon capture
[B] Serpentinisation
[C] Liquefaction
[D] Carbon capture
Correct Answer: B [Serpentinisation]
Notes:
The American Association of Petroleum Geologists and the United States Geological Survey (USGS) have recently launched formal hydrogen exploration initiatives. Hydrogen is seen as the fuel of the future due to its ability to help decarbonize the global economy and reduce greenhouse gas emissions. Natural hydrogen, or white hydrogen, is hydrogen that naturally occurs in the Earth’s crust, unlike industrially produced hydrogen. It forms through geological processes such as serpentinisation, where water reacts with iron-rich rocks, radiolysis, the breakdown of water by radioactive rocks, and the decomposition of organic matter in deep geological formations.

The NAMASTE Scheme was jointly launched by Ministry of Social Justice and Empowerment (MoSJE) and the Ministry of Housing and Urban Affairs (MoHUA) in 2023 to protect the safety and dignity of sanitation workers. Its wastepicker component was launched in 2024 with the goal to digitally profile and register 2.5 lakh wastepickers across India. It also provides health insurance under Ayushman Bharat–Pradhan Mantri Jan Arogya Yojana (PMJAY), and offers skill development training.

[A] Sudan
[B] Greece
[C] Japan
[D] Singapore
[B] Greece

[D] Singapore
Correct Answer: A [Sudan]
Notes:
The International Monetary Fund (IMF) recently projected that global public debt may surpass the COVID-19 pandemic level of 98.9% of Gross Domestic Product (GDP) recorded in 2020. Sudan now has the highest debt-to-GDP ratio in the world at 252%, due to long-term conflict and economic struggles. Among developed countries, Japan ranks second with a debt-to-GDP ratio of 234.9%, mainly due to fiscal deficits and an ageing population. The United States ranks eighth with a ratio of 123%, while France and Canada follow with 116.3% and slightly lower respectively. China ranks 21st globally with a public debt ratio of 96%, which is lower than many advanced economies. India stands at 31st with a debt-to-GDP ratio of 80%, and the central government aims to reduce it to 50±1% by March 31, 2031.
