Q3962. Following the Wildlife (Protection) Amendment Act, 2022, how many schedules does the Wildlife Protection Act, 1972 now contain?
Explanation
The Wildlife Protection Amendment Act of 2022 significantly rationalized the structure of the original 1972 Act. It reduced the total number of schedules from six to four. These updated schedules now cover animal species with high protection, species with lesser protection, protected plants, and a dedicated new schedule for species listed under the CITES appendices for international trade.
Q3963. Consider the following statements:
Statement I: In the 18th century, the Rajput nobility often asserted that the ruler was merely the ‘first among equals’.
Statement II: This ideology helped the rulers to centralize their administration and easily crush any feudal rebellion.
Statement I: In the 18th century, the Rajput nobility often asserted that the ruler was merely the ‘first among equals’.
Statement II: This ideology helped the rulers to centralize their administration and easily crush any feudal rebellion.
Explanation
During the eighteenth century, Rajput nobles often viewed the monarch as the ‘first among equals,’ reflecting a decentralized clan-based structure. This ideology, however, hindered rather than helped the rulers in centralizing their administration. Instead of crushing rebellions easily, monarchs frequently faced challenges from powerful feudal lords who asserted their traditional rights and autonomy against the central authority of the state.
Q3964. The discovery of extensive ancient slag heaps in the Aravalli region of Rajasthan suggests large-scale metallurgical activity. What was the direct effect of mastering zinc extraction techniques in ancient India?
Explanation
The mastery of zinc extraction was a major milestone in Indian metallurgy. By refining the process of recovering metallic zinc from ore, ancient practitioners were able to produce high-quality brass. This was achieved through the cementation process, where zinc vapor was absorbed by copper, resulting in an alloy that was durable, attractive, and widely used for various industrial and artistic purposes.
Q3965. Consider the following legislative tools allowing Parliament to intervene in the State List:
I. Article 249 (National Interest)
II. Article 250 (National Emergency)
III. Article 252 (Consent of States)
IV. Article 356 (President’s Rule) Under which of the above provisions does the State Legislature NOT lose its concurrent power to legislate on the same subject (though subject to repugnancy rules)?
I. Article 249 (National Interest)
II. Article 250 (National Emergency)
III. Article 252 (Consent of States)
IV. Article 356 (President’s Rule) Under which of the above provisions does the State Legislature NOT lose its concurrent power to legislate on the same subject (though subject to repugnancy rules)?
Explanation
Under Articles 249 and 250 the State Legislature keeps its power to legislate on the subject, though a conflict is settled in favour of the Union law. Under Articles 252 and 356 the position is different, so I and II only are correct.
Q3966. Given below are two statements, one labelled as
Assertion (A) and the other as Reason (R):
Assertion (A): The Great Green Wall initiative was initially conceived as a literal contiguous wall of trees stretching across Africa.
Reason (R): It has since evolved into a broad mosaic of targeted sustainable land management, agroforestry, and restoration practices tailored to local conditions.
Select the correct answer from the codes given below:
Assertion (A) and the other as Reason (R):
Assertion (A): The Great Green Wall initiative was initially conceived as a literal contiguous wall of trees stretching across Africa.
Reason (R): It has since evolved into a broad mosaic of targeted sustainable land management, agroforestry, and restoration practices tailored to local conditions.
Select the correct answer from the codes given below:
Explanation
The Great Green Wall was originally imagined as a continuous forest strip across Africa. Over time, the concept shifted toward a more integrated approach involving diverse restoration and sustainable management practices. This evolution reflects a growing understanding that local ecological and social conditions require tailored solutions. While both statements accurately describe the project’s history and current form, the evolution is a logical progression.
Q3967. The first phase of British treaties with the states of Rajputana occurred in 1803 during the Second Anglo-Maratha War. Which state was the first to sign a treaty of defensive alliance with the East India Company in 1803?
Explanation
During the early phase of British expansion in 1803, Bharatpur was the first Rajput state to sign a treaty of defensive alliance with the East India Company. This occurred under the governorship of Lord Wellesley during the Second Anglo- Maratha War. The treaty was intended to secure British interests by enlisting local support against the Maratha forces operating in northern India.
Q3968. Match the items in List I with the items in List II to identify the correct definitions of architectural terms.
| Rock-cut Architecture Terms | Precise Definitions |
|---|---|
| A. Chaitya | i. A residential hall or monastery for monks |
| B. Vihara | ii. A prayer hall containing a stupa at one end |
| C. Stupa | iii. A highly ornamented gateway |
| D. Torana | iv. A solid hemispherical mound containing relics |
Explanation
Rock-cut and Buddhist architecture utilizes specific terms for different structures. A Chaitya is a prayer hall that typically contains a stupa, while a Vihara serves as a residential hall for monks. A Stupa itself is a hemispherical mound used to house sacred relics, and a Torana refers to the elaborately decorated ceremonial gateways that stand at the entrances.
Q3969. In which of the following scenarios does the Parliament NOT have the authority to make laws on subjects enumerated in the State List?
Explanation
Parliament can legislate on State subjects to implement international agreements (Article 253), under President’s Rule (Article 356) and by a Rajya Sabha resolution (Article 249). A Financial Emergency under Article 360 does not give it that power.
Q3970. The Kigali Amendment to the Montreal Protocol, adopted in 2016, specifically targets the phase-down of which group of substances due to their high Global Warming Potential?
Explanation
The Kigali Amendment specifically addresses hydrofluorocarbons, which were introduced as ozone-friendly alternatives to chlorofluorocarbons. Although they do not deplete the ozone layer, they are extremely potent greenhouse gases with high global warming potential. By phasing down their use, the international community aims to avoid significant future warming. This amendment represents a crucial expansion of the Montreal Protocol’s environmental scope and impact.Answer key for these questions
