Q3841. Consider the following statements regarding the Rajput response to the declining Mughal authority: I. They attempted to expand their territories at the expense of weaker neighbors. II. They successfully negotiated a permanent peace treaty with the Maratha Peshwa in 1740. III. They frequently sought the military assistance of Maratha chieftains against rival Rajput clans. Which of the above statement(s) is/are correct?
Explanation
As Mughal authority waned, Rajput rulers attempted to expand their territories by encroaching on weaker neighbors. However, they failed to negotiate any permanent peace treaty with the Marathas. Instead, rival Rajput clans frequently sought Maratha military assistance to resolve internal succession conflicts, which only increased the Maratha influence and financial burden on the region’s states, rather than establishing long-term regional peace.

Q3842. Which of the following is not a characteristic feature of the Gandhara School of Art?
Explanation
The Gandhara school is famous for its anthropomorphic representation of the Buddha, depicting him in human form with realistic features. This style shifted away from earlier traditions where the Buddha was represented only through symbols. It is characterized by Greco-Roman influences, including realistic muscular details, thick drapery folds, and the use of bluish-grey schist and stucco.
Q3843. The protective ozone layer, which absorbs most of the Sun’s harmful ultraviolet radiation, is primarily located in which region of the atmosphere?
Explanation
The stratosphere contains the highest concentration of ozone, forming a protective shield around the planet. This layer absorbs the majority of the Sun’s harmful ultraviolet radiation, particularly UV-B rays. By filtering these rays, it prevents significant damage to living organisms and ecosystems. Its preservation remains a critical focus of international environmental agreements like the Montreal Protocol.

Q3844. Which region of the world is often referred to as the "lungs of the planet" due to its massive species diversity and ecological significance?
Explanation
The Amazon rainforest is frequently described as the lungs of the planet because of its immense capacity for oxygen production and carbon sequestration. Located in South America, it harbors an unparalleled richness of species. This vast tropical ecosystem plays a critical role in regulating global climate patterns and maintaining the atmospheric balance of gases essential for the survival of life.

Q3845. What was the primary cause for the failure of the Rajput rulers to maintain a united front after the death of Mughal Emperor Aurangzeb?
Explanation
Following the death of Aurangzeb, the Rajput states struggled to maintain unity against external threats. The primary cause for this failure was deep-seated mutual distrust and long-standing clan rivalries among the various Rajput houses. These internal divisions prevented the formation of a cohesive alliance, allowing external powers like the Marathas to exploit the situation for tribute and further destabilize the region.

Q3846. Identify the odd one out among the following sculptural traditions based on their primary geographic and stylistic origins in ancient India.
Explanation
Within the context of ancient Indian cultural development, the Gandhara, Mathura, and Amaravati traditions are classified as major schools of sculptural art that flourished during specific historical periods. In contrast, the Vesara tradition refers to a specific style of temple architecture that emerged later in the Deccan region, rather than a primary school of independent sculptural production.

Q3847. India is often described as a ‘quasi-federal’ state. What is the primary cause for this classification?
Explanation
India is termed quasi-federal because its constitutional structure is federal in form but unitary in spirit. While it maintains two levels of government, the Union possesses overriding powers, especially during emergencies. This unitary bias allows the central government to assume control over state subjects, ensuring national stability and security, which distinguishes India from more decentralized and traditional federal systems like America.
Q3848. All of the following are considered natural drivers of long-term climate change EXCEPT:
Explanation
Long-term climate variations occur naturally through Milankovitch cycles, solar fluctuations, and volcanic activity. However, large-scale changes in land use and the removal of forests are anthropogenic drivers. These human activities release stored carbon and alter surface albedo, contributing to modern global warming. Distinguishing between natural cycles and human-induced impacts is vital for accurate climate modeling.

Q3849. Find the odd one out in the context of biodiversity measurement levels.
Explanation
Alpha, beta, and gamma diversity are standard metrics established by ecologists to measure biodiversity at different spatial scales within a landscape. Alpha refers to local diversity, beta to species turnover between areas, and gamma to regional richness. Biome diversity is not a standard taxonomic or ecological measurement level used in this specific comparative framework for assessing biodiversity within regions.
