41. Which plant in Kerala is currently affected by the ambrosia beetle-fungus alliance?
[A] Tea
[B] Rubber
[C] Coconut
[D] Banana
Show Answer
Correct Answer: B [Rubber]
Notes:
In July 2025, Kerala’s rubber plantations faced a major threat from a beetle-fungus alliance causing severe leaf fall, tree drying, and reduced latex output. Researchers at the Kerala Forest Research Institute, Thrissur, identified the parasite as the ambrosia beetle (Euplatypus parallelus). It hosts two fungi — Fusarium ambrosia and Fusarium solani, marking the first report of F. solani with adult ambrosia beetles. The beetles bore tunnels in trees, farm fungi, and feed on fungal mycelia, while fungi weaken the tree’s structure with enzymes. These beetles were first reported in India in 2012 from cashew trees in Goa.
42. Oreshnik is a hypersonic ballistic missile developed by which country?
[A] China

44. Rubella disease, that was recently seen in news, is caused by which agent?
[A] Bacteria
[B] Virus
[C] Fungus
[D] Protozoa
Show Answer
Correct Answer: B [Virus]
Notes:
The World Health Organization (WHO) recently announced that Nepal has eliminated rubella as a public health problem. Rubella, also called German measles or three-day measles, is a contagious viral infection known for its red rash. It is caused by the Rubella virus, a single-stranded RNA virus, different from the measles virus. Rubella spreads through coughing, sneezing, contaminated surfaces, and from mother to fetus during pregnancy. This can lead to fetal death or Congenital Rubella Syndrome (CRS), causing hearing loss, eye and heart defects, autism, diabetes mellitus, and thyroid problems.
45. Which state government has launched India’s first Integrated Global Financial Technology Capability Hub (I-GFTCH)?
[A] Rajasthan
[B] Haryana
[C] Bihar
[D] Odisha
Show Answer
Correct Answer: D [Odisha]
Notes:
Odisha Chief Minister Mohan Charan Majhi unveiled India’s first Integrated Global Financial Technology Capability Hub (I-GFTCH) in Bhubaneswar under the BharatNetra initiative. It is launched with Singapore-headquartered Global Finance and Technology Network (GFTN). It aims to promote entrepreneurship, industry-ready skills, inclusive finance, and employment. Odisha plans Deep Neural Network laboratories and centres of excellence to boost research and development (R&D). The state produces 1.8 lakh graduates annually and is first in India to implement an Artificial Intelligence (AI) policy. A dedicated FinTech and Global Capability Centre (GCC) policy will attract global investments.
46. By using which method did scientists study fossil leaves from Nagaland to understand the evolution of Indian monsoons?
[A] Radiocarbon Dating
[B] Ice Core Analysis
[C] Dendrochronology
[D] CLAMP (Climate Leaf Analysis Multivariate Program)
Show Answer
Correct Answer: D [CLAMP (Climate Leaf Analysis Multivariate Program)]
Notes:
A study of fossil leaves from Nagaland revealed how Antarctica influenced the Indian Monsoons. Fossil leaves from the Laisong Formation in Nagaland revealed that the region once had a warm and wet climate with very high rainfall and temperatures. The fossils matched the period when massive ice sheets began forming in Antarctica, showing a global connection. Growth of Antarctic ice reshaped global wind and rainfall patterns by shifting the Intertropical Convergence Zone (ITCZ) toward the tropics. This shift brought intense monsoonal rains to Northeast India and led to the evolution of the monsoon system. The research used CLAMP (Climate Leaf Analysis Multivariate Program) method to analyze fossil leaves. CLAMP treats fossil leaves as “climate fingerprints” to reconstruct past climates.
47. What is the name of the asteroid recently confirmed as Earth’s latest quasi-satellite in September 2025?
[A] Victoria 2025
[B] Flora 2025
[C] 2025 PN7
[D] Cardea
Show Answer
Correct Answer: C [2025 PN7]
Notes:
Astronomers discovered asteroid 2025 PN7 in September 2025 as Earth’s latest quasi-satellite. ‘Quasi’ means almost; the asteroid is not gravitationally bound but orbits the Sun in resonance with Earth. It is an Arjuna-class near-Earth asteroid, named after Mahabharata’s Arjuna. 2025 PN7 orbits the Sun while staying close to Earth and will remain in this quasi-satellite state for approx 128 years. It was first spotted on August 2, 2025, by Panoramic Survey Telescope and Rapid Response System 1 (Pan-STARRS 1) in Hawaii.
48. Infectious Bovine Rhinotracheitis (IBR) disease, that was recently seen in news, is caused by which agent?
[A] Bacteria
[B] Virus
[C] Fungus
[D] Protozoa
Show Answer
Correct Answer: B [Virus]
Notes:
Indian Immunologicals Limited (IIL) has launched India’s first indigenously developed glycoprotein E (gE) deleted DIVA (Differentiated between Infected and Vaccinated Animal) marker vaccine against Infectious Bovine Rhinotracheitis (IBR) in Anand, Gujarat. IBR is caused by Bovine Herpes Virus-1 (BHV-1), belonging to the genus Varicellovirus under Alphaherpesvirinae subfamily. It mainly affects domestic and wild cattle. The disease has three forms – respiratory, genital and encephalitic, with respiratory and genital being common. Transmission occurs through aerosols and semen from bulls to milch animals, impacting the reproductive system.

[A] China
[B] Thailand
[C] Indonesia
[D] Philippines
Show Answer
Correct Answer: D [Philippines]
Notes:
The Philippines has launched Southeast Asia’s first Coral Larvae Cryobank, a major step to protect marine biodiversity. The cryobank is a scientific facility that freezes and stores coral larvae at ultra-low temperatures. It preserves the genetic material of corals for future reef restoration and scientific research. The facility acts like a “genetic seed vault” for corals to help safeguard biodiversity from climate change and coral bleaching. The project is part of the Coral Research and Development Accelerator Platform (CORDAP). Philippines, Taiwan, Indonesia, Malaysia, and Thailand are jointly participating in this regional conservation effort.
