Q4142. Which of the following statements correctly describes the legal nature of the recommendations made by the Finance Commission?
Explanation
The recommendations of the Finance Commission are purely advisory in nature. While the Union Government typically respects and implements these suggestions regarding tax devolution and grants, it is not legally bound to do so. The Constitution provides a flexible framework where the central government maintains the ultimate authority to decide on the final allocation of resources after considering the commission’s expert report.

Q4144. Identify the incorrect statement regarding the Snow Leopard.
Explanation
The snow leopard is famously known as the "Ghost of the Mountains" due to its elusive nature and serves as an indicator of high-altitude ecosystem health. Its diet primarily consists of wild sheep and goats. Uniquely, unlike other big cats like lions or tigers, the snow leopard lacks the laryngeal morphology required to roar, making the claim of frequent roaring scientifically incorrect.
Q4145. Which statement correctly describes the nature of the Rajput caste structure in 18th-century Rajasthan?
Explanation
The Rajput caste structure in eighteenth-century Rajasthan was characterized by a rigid hierarchy of sub-clans. This system was based on lineage, ancestry, and the relative political power held by different groups. While unified by a common identity, the sub-clans were strictly ranked, which influenced social interactions, marriage alliances, and the distribution of land and administrative authority in the states.

Reason (R): It evolved under the patronage of the Satavahanas and Ikshvakus, completely devoid of any indigenous Indian influence.
Assertion (A): The Amaravati school of art is renowned for its intense and emotionally expressive narrative reliefs.
Reason (R): It evolved under the patronage of the Satavahanas and Ikshvakus, completely devoid of any indigenous Indian influence.
Explanation
The Amaravati school is celebrated for its dynamic and emotionally charged narrative reliefs, which represent a high point in early Indian art. However, it was not devoid of indigenous influence. On the contrary, while it flourished under the Satavahanas and Ikshvakus and possibly had some contact with foreign styles, its artistic language remained deeply rooted in local traditions and themes.
Q4147. The Goods and Services Tax (GST) was introduced in the Indian Constitution through which Constitutional Amendment Act?
Explanation
The Goods and Services Tax (GST) was introduced through the 101st Constitutional Amendment Act in 2016. This landmark amendment replaced several indirect taxes levied by both the Union and the States with a unified tax structure. It fundamentally altered the fiscal landscape of India, promoting a common national market and requiring unprecedented cooperation between the central and regional governments in tax administration.
Q4148. Consider the following statements regarding strategies to combat climate change:
I. Mitigation involves taking action to reduce the emissions that cause climate change.
II. Adaptation involves adjusting to actual or expected future climate impacts.
III. Carbon Capture and Storage (CCS) is a widely deployed adaptation strategy in developing countries.
IV. Enhancing natural carbon sinks through afforestation is considered a mitigation strategy.
V. The Paris Agreement requires all countries to implement identical mitigation technologies regardless of their economic status.
Which of the above statement(s) is/are correct?
I. Mitigation involves taking action to reduce the emissions that cause climate change.
II. Adaptation involves adjusting to actual or expected future climate impacts.
III. Carbon Capture and Storage (CCS) is a widely deployed adaptation strategy in developing countries.
IV. Enhancing natural carbon sinks through afforestation is considered a mitigation strategy.
V. The Paris Agreement requires all countries to implement identical mitigation technologies regardless of their economic status.
Which of the above statement(s) is/are correct?
Explanation
Climate action involves both mitigation, which reduces emissions, and adaptation, which builds resilience to impacts. Afforestation is a key mitigation strategy as it enhances natural carbon sinks. However, complex technologies like Carbon Capture and Storage are not yet widely deployed in developing nations. Furthermore, the Paris Agreement recognizes different national circumstances, allowing for a variety of approaches rather than mandating identical technologies.
Q4149. The problem of ‘low-quality jobs’ in the service sector primarily highlights the fact that:
Explanation
The concern over ‘low-quality jobs’ highlights a structural issue where a large part of the service sector is concentrated in unorganized areas. These roles, such as domestic help and small-scale retail, are characterized by very low wages and a total lack of job security or social benefits. This ensures that while the sector grows, many workers remain in financial precariousness.
Q4150. The presence of a healthy population of Gangetic dolphins in a river segment indicates:
Explanation
The Gangetic dolphin is considered an apex predator in the riverine food web. Its presence in a river segment is a reliable indicator of a healthy freshwater ecosystem. Because these dolphins require clean water and an abundant supply of fish to survive, a thriving population suggests low pollution levels and high biodiversity in that particular stretch of the river system.Answer key for these questions
