1. Shingles Disease, that was recently seen in news, is caused by which agent?
[A] Bacteria
[B] Fungus
[C] Virus
[D] Protozoa
Show Answer
Correct Answer: C [Virus]
Notes:
A global survey found that 56.6% of Indians aged 50+ know little about shingles, though over 90% have the virus. Shingles (herpes zoster) is a viral infection causing a painful rash or blisters, often in a band-like pattern. It is caused by the varicella-zoster virus, which also causes chickenpox and can reactivate in adulthood. Shingles is not contagious, but the virus can spread to someone who never had chickenpox. Symptoms include pain, itching, fever, and fatigue. The Shingrix vaccine helps prevent shingles, and antiviral drugs can reduce its severity.
2. Which country recently deployed a powerful Large Phased Array Radar (LPAR) near the Myanmar border?
[A] China
[B] India
[C] Thailand
[D] Bangladesh
Show Answer
Correct Answer: A [China]
Notes:
China deployed a powerful Large Phased Array Radar (LPAR) in Yunnan province near the China-Myanmar border. It has a surveillance range of over 5,000 km, covering the Indian Ocean and deep into Indian territory. It can detect and track ballistic missile launches in real time. Unlike traditional radars, it uses electronically controlled antennas for instant scanning. It can track multiple targets, including ballistic missiles, with high precision. LPARs play a key role in early warning systems and air defense networks.

5. Which organization has launched Parker Solar Probe to study the sun?
[A] National Aeronautics and Space Administration (NASA)
[B] Indian Space Research Organisation (ISRO)
[C] European Space Agency (ESA)
[D] Japan Aerospace Exploration Agency (JAXA)
Show Answer
Correct Answer: A [National Aeronautics and Space Administration (NASA)]
Notes:
On March 22, 2025, NASA’s Parker Solar Probe reached 6 million km from the Sun, setting a new record for the closest spacecraft approach. It was launched on August 12, 2018, from Cape Canaveral, Florida. It aims to study the Sun’s corona, solar wind, and magnetic field. The probe follows a highly elliptical orbit, using Venus’ gravity to move closer to the Sun. It is the fastest human-made object, reaching speeds of 692,000 km/hr. It will ultimately come within 6.16 million km of the Sun, about seven times closer than any previous spacecraft.
6. What is the main objective of the Silvaguard drone system?
[A] To prevent lightning strikes
[B] To enhance real-time wildfire detection and firefighting efficiency
[C] To predict climate change trends
[D] To study wildlife migration patterns
Show Answer
Correct Answer: B [To enhance real-time wildfire detection and firefighting efficiency]
Notes:
Dryad Networks, a Berlin-based environmental Internet of Things (IoT) startup, introduced the Silvaguard drone for ultra-early wildfire detection. The Artificial Intelligence (AI)-based drone enhances fire detection, location, and monitoring using infrared imaging. It works with Silvanet, a solar-powered gas sensor network, detecting fires at the smoldering stage. Each sensor protects an area equal to a football field and attaches to trees. Once Silvanet detects a fire, Silvaguard flies to the location, captures video and infrared images, and sends real-time data to firefighters.
7. What is the causative agent of African Swine Fever, that was recently seen in news?
[A] Fungus
[B] Virus
[C] Bacteria
[D] Protozoa
Show Answer
Correct Answer: B [Virus]
Notes:
African Swine Fever (ASF) has resurged in Mizoram, causing 41 more pig deaths, raising the total toll to 503 since March 20. ASF first emerged in Mizoram in Lungsen village, Lunglei, on March 21, 2021, and has since become endemic. The causative agent of African Swine Fever (ASF) is the African Swine Fever Virus (ASFV). ASF is a highly contagious and fatal viral disease affecting domestic and wild pigs but poses no risk to humans. The virus can spread through contaminated clothing, equipment, or vehicles, threatening pig populations. There is no treatment or vaccine, making prevention and strict biosecurity measures the only effective control methods.
8. The government has launched ZooWIN, a digital platform to track the availability of which two types of medical supplies?
[A] Malaria medicines and dengue vaccines
[B] Anti-rabies vaccines (ARV) and anti-snake venom (ASV)
[C] COVID-19 vaccines and polio vaccines
[D] None of the Above
Show Answer
Correct Answer: B [Anti-rabies vaccines (ARV) and anti-snake venom (ASV)]
Notes:
The government has launched ZooWIN, a digital platform to track real-time availability of anti-rabies vaccines (ARV) and anti-snake venom (ASV) nationwide. ZooWIN is similar to Co-WIN and U-WIN, centralizing data for better coordination among healthcare providers, municipal authorities, and veterinary services. It supports the Union Health Ministry’s efforts to combat rabies and snakebites under the National Action Plan for Prevention and Control of Snakebite Envenoming (NAPSE). India records 3–4 million snakebites annually, causing around 50,000 deaths, half of the global snakebite mortality. The platform is initially piloted in Delhi, Madhya Pradesh, Assam, Puducherry, and Andhra Pradesh.
9. What kind of satellite is “CARTOSAT-3” that was recently seen in news?
[A] Earth Observation Satellite
[B] Communications Satellite
[C] Navigation Satellite
[D] Astronomical Satellite
Show Answer
Correct Answer: A [Earth Observation Satellite]
Notes:
Indian Space Research Organisation’s (ISRO) CARTOSAT-3 satellite captured high-resolution images of earthquake damage in Myanmar. A 7.7-magnitude earthquake struck Myanmar on March 28, 2025. Post-disaster images from March 29 were compared with pre-event data from March 18 to assess damage in Mandalay and Sagaing. CARTOSAT-3 is a third-generation agile advanced Earth observation satellite developed by ISRO. It replaces the Indian Remote Sensing (IRS) series and has high-resolution imaging capabilities. It was launched aboard the Polar Satellite Launch Vehicle (PSLV-C47).

Notes:
The Indian Council of Agricultural Research -Central Tuber Crops Research Institute (ICAR-CTCRI) developed an orange-fleshed sweet potato variety (SP-95/4) to improve tribal food security in Kerala and other states. It successfully passed final trials in Odisha, West Bengal, Karnataka, and Kerala. It contains 8 mg/100g of Beta-carotene, helping combat Vitamin A deficiency in tribal areas. The average tuber weighs 300 grams and has a fusiform shape, making it ideal for processing. The project, currently on 10-15 acres, aims to expand to 100 acres by 2025 with Corporate Social Responsibility (CSR) funding. Research trials confirmed its high yield potential in multiple states, including Odisha and Karnataka.
