44. Which species is the natural host of “Nipah Virus” that was recently reported in Kerala?
[A] Ant
[B] Fruit bat
[C] Mosquito
[D] Housefly
Show Answer
Correct Answer: B [Fruit bat]

Recently, the Kerala Health Minister confirmed 425 people are on the Nipah virus contact list across the state. Nipah Virus (NiV) is an emerging zoonotic virus spreading from animals to humans. It can also spread through contaminated food or directly from person to person. Fruit bats from the Pteropodidae family are its natural hosts. NiV infection can be without symptoms, mild, or cause serious breathing illness and deadly brain swelling.
45. Which space organization has launched a twin satellite mission called “TRACERS” to study Earth’s magnetic shield?
[A] European Space Agency (ESA)
[B] National Aeronautics and Space Administration (NASA)
[C] Japan Aerospace Exploration Agency (JAXA)
[D] Indian Space Research Organisation (ISRO)
Show Answer
Correct Answer: B [National Aeronautics and Space Administration (NASA)]
Notes:
Recently, NASA launched a twin satellite mission called TRACERS, which stands for Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites. The satellites were launched from Vandenberg Space Force Base, California, aboard a SpaceX Falcon 9 rocket. The mission aims to study magnetic reconnection, a powerful process where magnetic field lines snap and release energy. This process happens when solar wind, a stream of charged particles from the Sun, interacts with Earth’s magnetosphere (magnetic shield).
46. What kind of disease is African Swine Fever (ASF) that was recently seen in news?
[A] Bacterial disease
[B] Fungal disease
[C] Viral disease
[D] Parasitic disease
Show Answer
Correct Answer: C [Viral disease]
Notes:
Recently, African Swine Fever (ASF) outbreak was confirmed at a pig farm in Ravas Brahmanan village, Patiala, Punjab. District authorities have taken immediate action to contain the spread. African Swine Fever (ASF) is a highly contagious viral disease affecting domestic pigs and wild boars. It does not affect humans or other animal species. It causes high mortality (up to 90–100%) and severely impacts pig farming. It originated in sub-Saharan Africa and has spread to Europe, Asia, and Africa. In India, it was first detected in Arunachal Pradesh and Assam in Feb–Mar 2020.
47. Which company became the first in India to secure the ISCC CORSIA certification for Sustainable Aviation Fuel (SAF)?
[A] Bharat Petroleum Corporation Ltd. (BPCL)
[B] Hindustan Petroleum Corporation Ltd. (HPCL)
[C] Indian Oil Corporation Ltd. (Indian Oil)
[D] None of the Above
Show Answer
Correct Answer: C [Indian Oil Corporation Ltd. (Indian Oil)]
Notes:
Indian Oil Corporation Ltd. (Indian Oil) became the first company in India to secure International Sustainability & Carbon Certification (ISCC) CORSIA for Sustainable Aviation Fuel (SAF) at its Panipat Refinery. The certification is mandatory for commercial SAF production and aligns India with global aviation fuel standards. Certificate was handed over by Cotecna to Indian Oil Chairman A.S. Sahney in New Delhi. ISCC CORSIA, developed under Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) of International Civil Aviation Organization (ICAO), ensures sustainability and lifecycle carbon standards.
