Stratospheric ozone is essential for life as it absorbs harmful ultraviolet radiation. However, ground-level or tropospheric ozone is a harmful pollutant and a key component of smog.

Explanation
According to the IUCN Red List criteria, a taxon is categorized as Vulnerable when the best available evidence indicates that it meets specific thresholds for population size or range decline.

Q3945. The following question consists of two statements -- Assertion (A) and Reason (R). Answer the question by selecting the appropriate option. Assertion (A): The Vesara style of temple architecture is prominently observed in the Deccan region. Reason (R): The Vesara style originated as an independent architectural order completely uninfluenced by the pre-existing Nagara and Dravida styles.
Explanation
The Vesara style is a prominent architectural order found in the Deccan region, particularly under the Chalukyas and Hoysalas. However, it was not an entirely independent or uninfluenced style. It actually developed as a hybrid, selectively combining the curvilinear elements of the northern Nagara style with the tiered towers and architectural layout of the southern Dravida style.

Q3946. Consider the following circumstances: I. When the Rajya Sabha passes a resolution supported by not less than two-thirds of the members present and voting. II. When a National Emergency is in operation. III. When the Legislative Assembly of a single State requests the Parliament to do so. Under which of the above circumstances can the Parliament legislate on a matter in the State List?
Explanation
Parliament can legislate on a State List subject when the Rajya Sabha passes a resolution by a two-thirds majority of members present and voting (Article 249) and while a National Emergency is in force (Article 250). A request from one State Assembly is not enough, so III is wrong.
Q3947. Consider the following statements regarding the causes of desertification globally: I. Overgrazing removes vegetative cover, exposing soil to wind and water erosion. II. Deforestation for fuelwood is a significant driver of desertification in developing nations. III. Sustainable crop rotation practices accelerate the rate of desertification. IV. Improper irrigation can lead to salinization, making soils toxic to crops. V. Prolonged natural droughts exacerbate human-induced land degradation. Which of the above statement(s) is/are incorrect?
Explanation
Desertification is driven by unsustainable practices like overgrazing, deforestation for fuel, and improper irrigation leading to salinization. Conversely, sustainable crop rotation is a beneficial agricultural technique that helps maintain soil fertility and structure. It reduces the risk of land degradation rather than accelerating it. Therefore, promoting such sustainable methods is a key strategy in the global fight against encroaching desertification.

Q3948. Identify the incorrect statement regarding the IUCN Red List.
Explanation
The IUCN Red List is a scientifically rigorous system that relies heavily on quantitative criteria. These include measurable data on population size reduction, geographic range size, and probability of extinction. It does not rely solely on qualitative descriptions. Species in the Vulnerable, Endangered, and Critically Endangered categories are collectively identified as Threatened, and the list informs global conservation policies.

Q3949. The principality of Tonk was formally recognized as a sovereign state by the British in 1817 and granted to which of the following leaders?
Explanation
The British formally recognized Tonk as a sovereign principality in 1817 as part of their strategy to stabilize the region. This state was granted to the Pindari leader Amir Khan after he agreed to disband his mercenary forces and cooperate with the East India Company. This arrangement effectively transitioned a powerful military commander into a recognized territorial ruler under British protection.
