The Indian Navy's 'Operation Sankalp' is a measure taken to safeguard which of the following?
A India's land borders
B Indian merchant vessels and national interests in the maritime domain
C Indian fishing communities along the coast
D Naval bases in the Andaman and Nicobar Islands
Answer: B
Operation Sankalp is designed to protect Indian-flagged vessels and ensure the safety of Indian interests in the face of potential threats in the Arabian Sea, particularly in the context of international maritime security.
53.
Which region is the primary focus of the Indian Navy's 'Operation Sankalp'?
A Bay of Bengal
B Indian Ocean
C Arabian Sea, particularly the Strait of Hormuz area
D Andaman Sea
Answer: C
Operation Sankalp is specifically focused on the Arabian Sea, with a particular emphasis on the Strait of Hormuz and the Persian Gulf, to monitor and deter threats to maritime shipping.
54.
Operation Sankalp, conducted by the Indian Navy in the Arabian Sea, primarily aims to:
A Conducting anti-piracy patrols and ensuring maritime security.
B Testing new submarine technologies.
C Participating in joint naval exercises with allied nations.
D Escorting merchant vessels through sensitive sea lanes.
Answer: A
Operation Sankalp was launched by the Indian Navy in June 2019 in response to the escalating tensions and increased incidents of maritime attacks in the Strait of Hormuz and the Persian Gulf region, aiming to ensure the safety and security of Indian maritime interests and vessels.

What is a key advantage of integrating AI into healthcare diagnostics, particularly in regions with limited access to specialized medical professionals?
A Increased reliance on manual data entry
B Reduction in the need for any human oversight
C Enhanced diagnostic accuracy and scalability of screening programs
D Higher overall cost of diagnostic procedures
Answer: C
AI-powered diagnostic tools can significantly enhance diagnostic accuracy by identifying subtle patterns often missed by human eyes. More importantly, they offer scalability, allowing for widespread screening programs in underserved areas, thereby improving access to early diagnosis without requiring a proportional increase in specialized human experts.
56.
AI models are increasingly being utilized for the early and accurate diagnosis of which specific eye condition by analyzing retinal images, significantly aiding in preventing vision loss?
A Cataracts
B Glaucoma
C Diabetic Retinopathy
D Macular Degeneration
Answer: C
AI algorithms have achieved high accuracy in detecting signs of diabetic retinopathy from retinal scans, often outperforming human experts in initial screening. This breakthrough is crucial for early intervention and preventing irreversible vision loss in diabetic patients.
57.
By 2026, AI-powered diagnostics have shown significant breakthroughs in which medical specialty, particularly in enhancing the accuracy and speed of interpreting complex medical images?
A Orthopedics
B Radiology
C Dentistry
D Ophthalmology
Answer: B
AI has made substantial progress in radiology, where algorithms can analyze X-rays, CT scans, and MRIs to detect anomalies, assist in disease diagnosis (e.g., cancer, pneumonia), and improve workflow efficiency for radiologists. While AI is also used in ophthalmology, radiology represents a broader and more impactful breakthrough in image interpretation across various diseases.

The Next-Gen Launch Vehicle (NGLV) is intended to serve as a successor or complement to which of ISRO's current operational heavy-lift launch vehicles for future missions?
A Polar Satellite Launch Vehicle (PSLV)
B Small Satellite Launch Vehicle (SSLV)
C Launch Vehicle Mark-3 (LVM3, formerly GSLV Mk III)
D Geosynchronous Satellite Launch Vehicle (GSLV Mk II)
Answer: C
NGLV is being designed as a heavy-lift, reusable launch vehicle with a payload capacity of 10-tonne to GTO, aiming to replace or complement the LVM3 (GSLV Mk III) for future heavy satellite launches and human spaceflight missions.
59.
Which advanced propulsion technology is ISRO primarily developing for the Next-Gen Launch Vehicle (NGLV) to achieve higher payload capacity and efficiency?
A Solid rocket boosters
B Hypergolic liquid engines
C Semi-cryogenic engines
D Electric propulsion systems
Answer: C
ISRO is focusing on developing semi-cryogenic engines for NGLV. These engines use refined kerosene (RP-1) as fuel and liquid oxygen (LOX) as oxidizer, offering a higher thrust-to-weight ratio and being more cost-effective than fully cryogenic engines.
60.
What is the primary design characteristic of ISRO's proposed Next-Gen Launch Vehicle (NGLV) aimed at significantly reducing launch costs and increasing mission frequency?
A Fully expendable design
B Single-stage to orbit capability
C Reusability of the first stage
D Exclusive use of solid propellants
Answer: C
The Next-Gen Launch Vehicle (NGLV) is envisioned as a heavy-lift, reusable rocket, with reusability of the first stage being a key feature to reduce launch costs and enable higher launch frequency, similar to SpaceX's Falcon 9.
