Q3602. Among the following classifications of agricultural land, which one generally yielded the lowest land revenue rate to the state?
Explanation
Barani land refers to agricultural plots that are entirely dependent on rainfall for irrigation. Because rain-fed farming is less reliable and generally yields lower harvests compared to irrigated lands like Chahi or Nahari, the state typically imposed the lowest land revenue rates on Barani holdings. This lower rate helped compensate for the high risk of crop failure due to unpredictable weather.
Q3603. The world-renowned Chola bronze sculptures were primarily cast using which of the following traditional metallurgical techniques?
Explanation
Chola bronze sculptures are world-famous for their grace and technical perfection. They were created using the Cire-perdue or lost-wax casting method. In this process, a detailed wax model is covered in clay and heated to melt the wax away, leaving a hollow mold. Molten bronze is then poured into the cavity to create a solid metal image. This sophisticated technique allowed Chola artisans to achieve a high level of intricate detail and fluid movement in their sculptures.
Q3604. "Justice delayed is justice denied." In the context of the Indian Judiciary, which of the following is an oft-cited reason for judicial delays leading to judicial activism?
Explanation
A major challenge facing the Indian judiciary is the massive backlog of cases and numerous vacancies in judicial positions across all levels. These factors contribute significantly to delays in the delivery of justice. Such systemic inefficiencies often prompt the judiciary to adopt an activist role to address urgent social issues that might otherwise remain unresolved for many years in the regular system.
Q3605. What is the primary economic cause for the North Atlantic route being the busiest ocean trade route globally?
Explanation
The North Atlantic route’s status as the busiest ocean trade lane is driven by the immense economic power of the regions it connects. Western Europe and North America are among the most industrially advanced and high-income areas in the world. This results in high demand for the exchange of manufactured goods, specialized technology, and raw materials, generating massive and consistent traffic.
Q3606. The Ease of Doing Business (EoDB) index, which evaluated business regulations across countries, was published annually by which international organization before its discontinuation?
Explanation
The Ease of Doing Business index was a prominent annual ranking published by the World Bank Group. It evaluated the regulatory environment for businesses across different countries based on several standardized parameters. The index played a significant role in influencing national policy reforms as countries competed to improve their rankings. However, the World Bank discontinued the report in 2021 following internal audits regarding data.
Q3607. Which agricultural practice is a major contributor to soil pollution?
Explanation
Modern farming often relies heavily on the application of synthetic chemicals to control pests and boost crop yields. While these products can be effective in the short term, their excessive and improper use leads to the accumulation of toxic residues in the ground. These chemicals can harm beneficial soil organisms, disrupt natural nutrient cycles, and eventually leach into the local groundwater supplies.
Q3608. Arrange the following types of land in general order of their revenue yield per bigha, from highest to lowest, based on standard medieval assessment practices:
Explanation
Revenue yield per bigha was highest on Chahi land due to its consistent irrigation from wells. Barani land followed, yielding moderate returns depending on rainfall. Magra land, being stony or hilly, typically had the lowest productivity and consequently the lowest revenue assessment.
Q3609. In the iconic Chola bronze sculpture of Nataraja, what does the dwarf demon (Apasmara Purusha) being trampled under Lord Shiva’s right foot symbolize?
Explanation
In the Nataraja icon, Lord Shiva is depicted performing the cosmic dance of Tandava. He tramples upon a dwarf-like figure known as Apasmara Purusha. This demon is not a literal creature but a powerful symbol representing human ignorance, forgetfulness, and the deluding power of the ego. By pinning the demon down, Shiva symbolizes the destruction of these spiritual obstacles, which is a necessary step for the devotee to achieve enlightenment and liberation from the cycle of suffering.
Q3610. Which of the following major global seaports does NOT primarily operate on or cater directly to the North Atlantic trade route?
Explanation
New York, Rotterdam, and London are all major ports that sit directly on or serve as key terminals for the North Atlantic trade route, linking the US and Europe. Singapore, however, is a strategic hub in Southeast Asia. It serves as a gateway between the Indian and Pacific Oceans, catering primarily to trade routes connecting Asia with Europe and other nations.Answer key for these questions
