Q3892. The Nicobar Islands of India form a part of which global biodiversity hotspot?
Explanation
The Nicobar Islands are geologically and biologically linked to the Southeast Asian archipelago, placing them within the Sundaland biodiversity hotspot. This region includes the Malay Peninsula and various Indonesian islands. While the Andaman Islands are often associated with the Indo-Burma hotspot, the Nicobars represent India’s contribution to the extremely rich and threatened Sundaland ecological zone in the Indian Ocean.

In the architectural language of the Nagara style, the Amalaka is a crucial structural and symbolic element.

Q3896. Consider the following statements regarding the causes of desertification:
Statement I: Improper irrigation practices in arid and semi-arid regions can lead to waterlogging and severe soil salinization.
Statement II: The accumulation of salts in the topsoil makes it unviable for agriculture, thereby accelerating the process of desertification.
Which of the above statement(s) is/are correct?
Statement I: Improper irrigation practices in arid and semi-arid regions can lead to waterlogging and severe soil salinization.
Statement II: The accumulation of salts in the topsoil makes it unviable for agriculture, thereby accelerating the process of desertification.
Which of the above statement(s) is/are correct?
Explanation
Improper irrigation in drylands often leads to waterlogging and the subsequent accumulation of salts in the topsoil. This process, known as salinization, makes the land toxic for most crops and vegetation.
Q3897. Identify the incorrect pair regarding India’s biodiversity hotspots and their prominent regions.
Explanation
The Sundaland hotspot in India primarily includes the Nicobar Islands, while the Indo- Burma hotspot covers the northeastern states. The Himalayas hotspot encompasses the mountain range in Arunachal Pradesh. However, the Lakshadweep Islands are coral atolls in the Arabian Sea and are not classified as part of the Sundaland hotspot, making this specific pairing incorrect and factually inaccurate.

Following his death, her engagement to Jagat Singh of Jaipur caused Maharaja Man Singh to object, claiming the alliance belonged to the Jodhpur house. The dispute was not resolved peacefully but ended tragically with the princess being poisoned to prevent further warfare among the rival Rajput states.
Q3899. Select the correct chronological sequence of the evolution of sculptural art styles in ancient India from the options given below.
Explanation
The sculptural traditions of ancient India followed a clear chronological progression. Mauryan art introduced polished stone pillars and court art, followed by the narrative reliefs of the Sunga period. The Kushana period saw the emergence of the Mathura and Gandhara schools, while the Gupta period marked the classical peak characterized by spiritual serenity and refined aesthetic balance.
Q3900. How does the melting of Arctic ice contribute to a positive feedback loop in global climate change?
Explanation
The melting of Arctic sea ice reduces the Earth’s albedo, which is the reflectivity of the surface. White ice reflects sunlight, but dark open water absorbs more solar energy, leading to further warming. This additional heat causes more ice to melt, creating a self-reinforcing positive feedback loop. This mechanism significantly accelerates the rate of warming in polar regions.Answer key for these questions
