Which of the above statement(s) is/are correct?
Explanation
Ahar architecture is characterized by multi-roomed houses built on sturdy schist stone platforms. The superstructures were made of mud or sun-dried bricks, as baked bricks were not commonly used for residential construction. A notable feature is the discovery of multi-faced hearths, suggesting large communal cooking or joint families. These structures reflect a well-organized rural society adapted to the local resources.

IV. Indira Gandhi Canal has significantly altered the agricultural landscape of its north-western part.
Which of the above statement(s) is/are correct?
Explanation
The Thar Desert is bounded by the Aravalli Range to its east and is notable for having the highest human population density of any desert. The Indira Gandhi Canal has transformed agriculture in its northwestern regions. However, the desert soil is primarily sandy rather than black cotton soil. These features highlight the unique ecological and demographic character of the Great Indian Desert.
Q406. In ecological footprint analysis, the term "biocapacity" refers to:
Explanation
Biocapacity refers to the ability of an ecosystem to regenerate biological resources and absorb the waste materials generated by humans. It is a measure of the planet’s productive area, including forests, croplands, and fishing grounds. When human demand exceeds this capacity, the ecosystem becomes degraded. Comparing biocapacity to the ecological footprint helps identify whether a region is living sustainably or unsustainably.
Q407. Which of the following medical applications utilizes sound waves above the human hearing limit?
Explanation
Ultrasonography is a medical imaging technique that utilizes high-frequency sound waves, well above the human hearing limit of twenty thousand Hertz. These ultrasonic waves are directed into the body and reflect off internal organs and tissues. The returning echoes are captured and processed by a computer to create real-time images, making it a safe and non-invasive tool for diagnostic monitoring.
Q408. Which architectural feature is notably absent in the general habitation structures of the Ahar site?
Explanation
While the Ahar culture displayed sophisticated rural planning, baked bricks are notably absent in its general habitation structures. Instead, the Ahar people utilized locally available stone for foundations and sun-dried mud bricks or wattle-and-daub for walls. Roofs were typically thatched with bamboo and grass. The lack of baked bricks distinguishes Ahar from urban Harappan sites, emphasizing its distinct rural character.
Q409. Harappan craftsmen commonly used a material called faience. What was it primarily used for?
Explanation
Faience is a glazed ceramic material made from ground sand or silica mixed with color and a gum. Harappan craftsmen used it extensively to create small, luxury items. These included miniature vessels, beads, bangles, and figurines. Because it required a complex manufacturing process, faience objects are often considered prestige items, reflecting the technical skill and artistic taste of the population.
Q410. Which of the following best describes the constitutional ideal of ‘Fraternity’?
Explanation
Fraternity refers to a sense of common brotherhood among all Indians. The Preamble aims to promote this fraternity to ensure two things: the dignity of the individual and the unity and integrity of the nation.
