Q4272. Which of the following statements about the Punchhi Commission’s view on the removal of the Governor is incorrect?
Explanation
The Punchhi Commission actually criticized the arbitrary removal of Governors and recommended deleting the phrase pleasure of the President from the Constitution. It argued for a fixed tenure and a formal impeachment process by the state legislature to protect the Governor from political interference by the Union. This view directly contradicts the idea of maintaining central control through the pleasure doctrine, aiming instead for gubernatorial independence.
Q4273. The ‘Kavach’ system, recently in the news, is associated with the safety infrastructure of which service sector?
Explanation
Kavach is an indigenously developed automatic train protection system designed to enhance safety in the Indian railways. It acts as an anti-collision system that prevents trains from passing signals at danger and helps avoid accidents in adverse weather conditions. The implementation of this technology is a critical part of the modernization efforts to make rail travel safer through advanced electronic safety protocols.
Q4274. Which of the following is the most appropriate reason for using cryopreservation in biodiversity conservation?
Explanation
Cryopreservation is a sophisticated ex-situ conservation technique used to store biological materials like seeds, pollen, and animal gametes. By using liquid nitrogen to achieve ultra-low temperatures, usually around minus 196 degrees Celsius, genetic material can be preserved for decades without losing its viability. This method provides a "genetic backup" for endangered species that might face sudden extinction in the wild.
Q4275. What defines a ‘unicorn’ in the context of the digital economy and startup ecosystem?
Explanation
In the startup ecosystem, a ‘unicorn’ is a privately held company that has reached a valuation of over one billion US dollars. This status signifies significant growth, investor confidence, and market potential. India has seen a rapid rise in the number of unicorns, particularly in the fintech, e-commerce, and edtech sectors. This trend reflects the vibrant nature of the domestic digital economy.
Q4276. Botanical gardens play a significant role in conservation by:
Explanation
Botanical gardens serve as critical ex-situ conservation facilities by cultivating and maintaining living collections of diverse plant species. They focus on preserving rare, endemic, and threatened plants that may be at risk in their natural habitats. These institutions also conduct research on plant propagation and public education, playing a vital role in global efforts to prevent the loss of floral diversity.
Q4277. In the context of the economic history of Rajasthan, a ‘Hundi’ can best be defined as:
Explanation
A Hundi was a bill of exchange or credit note used in long-distance trade. Merchants used it to move money without carrying cash.
Q4278. An individual in Rajasthan uses a mobile application to instantly transfer funds to a merchant’s bank account using a QR code. This process relies on which underlying core technology?
Explanation
Real-time fund transfers using mobile applications and QR codes are made possible by the Unified Payments Interface.
Q4279. Severe and irreversible fragmentation of a species’ natural habitat often leads conservationists to:
Explanation
When a species’ natural habitat becomes severely and irreversibly fragmented, in-situ conservation may no longer be sufficient to ensure its survival. In such extreme cases, conservationists must implement ex-situ measures, such as captive breeding programs in zoos or specialized centers. These efforts aim to stabilize the population and preserve the species’ genetic lineage until potential reintroduction into the wild becomes feasible.
Q4280. Identify the incorrectly matched pair of a prominent historical merchant/banker family and their primary base in Rajasthan:
Explanation
Prominent merchant families in Rajasthan had specific historical bases, such as Seth Mirzamal in Churu and the Lodha family in Ajmer. Amar Chand Banthia was associated with Bikaner and Gwalior. However, the Birla family’s traditional roots are in Pilani, Shekhawati, rather than Jaisalmer. These families were central to the regional banking system and later became major industrial figures in India.Answer key for these questions
