Q3851. The following question consists of two statements -- Assertion (A) and Reason (R). Answer the question by selecting the appropriate option. Assertion (A): The Gandhara school of art is frequently referred to as Greco-Buddhist art. Reason (R): It seamlessly combined Indian Buddhist themes with Hellenistic and Roman aesthetic techniques.
Explanation
The Gandhara school of art is widely recognized as Greco-Buddhist art due to its unique aesthetic fusion. It emerged in the northwestern frontier, where local Buddhist themes were expressed using Hellenistic and Roman artistic techniques. The realistic treatment of the human body and the specific style of drapery reflect the seamless combination of these two diverse cultural traditions.

Q3852. Consider the following statements regarding the legislative relations between the Union and the States: I. Article 245 defines the territorial extent of laws made by Parliament and State Legislatures. II. Article 246 completely debars Parliament from making laws on items enumerated in the State List under any circumstance. III. Article 254 deals with the inconsistency between laws made by Parliament and laws made by the Legislatures of States. Which of the above statement(s) is/are correct?
Explanation
Article 245 defines the territorial extent of legislative powers, and Article 254 addresses inconsistencies between Union and State laws on concurrent subjects. While Article 246 distributes legislative powers across three lists, it does not completely debar Parliament from making laws on state subjects.
Q3853. Consider the following statements regarding Amazon deforestation: I. The Amazon basin contains the largest remaining area of tropical rainforest in the world. II. Cattle ranching and soy cultivation are among the leading primary drivers of deforestation in the region. III. Deforestation in the Amazon reduces its capacity to function as a global carbon sink. IV. The loss of Amazonian tree cover has no significant impact on regional evapotranspiration and rainfall patterns. V. Scientists warn that continued deforestation could push the Amazon past a tipping point, turning it into a savanna. Which of the above statement(s) is/are correct?
Explanation
The Amazon basin represents the largest tropical forest, providing essential services like carbon sequestration and regional rainfall regulation through evapotranspiration. Major drivers include cattle ranching and soy cultivation. Continued loss of tree cover threatens a potential tipping point where the ecosystem transforms into a savanna. This shift would have catastrophic consequences for global biodiversity and climate stability.

Q3854. Match the following terms in List I with their definitions in List II:
Term
Definition
A. Alpha diversity
i. Overall diversity within a large region or landscape
B. Beta diversity
ii. Diversity within a particular area or ecosystem
C. Gamma diversity
iii. Variation of alleles within a population
D. Genetic diversity
iv. Change in species composition along an environmental gradient Options:
Explanation
Alpha diversity identifies the number of species within a specific local area. Beta diversity evaluates the change in species composition along environmental gradients. Gamma diversity reflects the total biodiversity across a large regional landscape. Genetic diversity focuses on the variation of alleles within a population, ensuring that each concept is correctly mapped to its standardized ecological and biological definition.

Q3855. In the context of Maratha invasions in Rajputana, the financial exaction levied by the Marathas to spare a territory from plunder was commonly known as:
Explanation
During the eighteenth century, Maratha forces frequently invaded Rajputana primarily for financial extraction. They levied a specific tribute known as Chauth, which was theoretically one-fourth of the land revenue. Paying this amount was necessary for a territory to be spared from systematic plunder and raids by the Maratha armies, becoming a regular and burdensome feature of regional politics and state finance.

Q3856. Read the following statements regarding the mural paintings of Ajanta: Statement I: The paintings were executed using the true fresco technique where pigments are applied to wet plaster. Statement II: The principal themes of these paintings are the Jataka stories and the life of Gautama Buddha. Which of the following is correct?
Explanation
The mural paintings found at Ajanta are primarily dedicated to depicting the Jataka stories and various stages of the Buddha’s life. However, technical analysis shows they were not executed using true fresco techniques on wet plaster. Instead, artists employed the tempera method, where pigments were applied to a prepared layer of dry mud and lime plaster.

Q3857. According to the Constitution of India, who possesses the power to make laws with ‘extra-territorial operation’?
Explanation
Under Article 245 of the Indian Constitution, only the Parliament possesses the authority to make laws with extra-territorial operation. This means parliamentary laws can apply to Indian citizens and their property located anywhere in the world. Conversely, laws enacted by State Legislatures are strictly confined to the territorial limits of the respective state and cannot have legal effects outside those regional boundaries.
Q3858. Which of the following statements accurately describes the primary role of the Intergovernmental Panel on Climate Change (IPCC)?
Explanation
The Intergovernmental Panel on Climate Change does not conduct original research or monitor the atmosphere directly. Instead, it systematically reviews and synthesizes thousands of peer-reviewed scientific papers. This process provides policymakers with a comprehensive summary of climate drivers, impacts, and mitigation options. Its assessments form the scientific foundation for international climate negotiations and policy development.

Q3859. Identify the incorrect statement regarding species diversity.
Explanation
Species diversity involves richness, the total number of species, and evenness, the relative abundance of each species. Ecosystem stability generally increases with higher diversity and evenness. A community dominated by only a few species is typically more vulnerable to disturbances. Therefore, claiming that highly uneven species distribution leads to ecosystem stability is ecologically incorrect and contradicts standard biological principles.
