⢠Question 1 of 10 1. Question 1 points With reference to the classical Tamil text âTirukkuralâ, consider the following statements: It is traditionally structured into three books focusing on virtue, wealth, and love. The text is composed of over a thousand concise couplets known as kurals. It is primarily a religious scripture dedicated to the Vedic deities of South India. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B The Tirukkural is one of the most revered classical Tamil texts, traditionally attributed to the poet-philosopher Thiruvalluvar. Its structure is distinct, comprising 1,330 short couplets (kurals) divided into three sections or books: Aram (Virtue), Porul (Wealth/Polity), and Inbam (Love). This tripartite structure mirrors the purusharthas (aims of human life) but remains uniquely rooted in Tamil intellectual traditions. One of the most significant characteristics of the Tirukkural is its universal and secular tone. While it is often respectfully referred to as the âTamil Veda,â it does not function as a religious scripture dedicated to specific deities. Instead, it offers a secular ethical framework for personal conduct, effective governance, and social harmony. It emphasizes values like compassion, non-violence, and integrity that transcend sectarian boundaries, making it applicable to people of all faiths. The brevity of its aphorisms allows for profound philosophical depth within just seven words per couplet. Because the text focuses on practical morality rather than religious dogma or Vedic rituals, statement 3 is incorrect.

⢠Question 2 of 10 2. Question 1 points Consider the following statements regarding âIndelible Inkâ used in Indian elections: It contains silver nitrate, which reacts with the keratin in the skin to form a permanent mark. The ink is produced by the National Physical Laboratory under the Ministry of Science and Technology. The mark on the skin typically fades within a few days, while the mark on the nail lasts until the nail grows out. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Indelible ink is a cornerstone of electoral integrity in India, introduced during the Third General Election in 1962 to prevent multiple voting. Its chemical composition relies on silver nitrate. When applied to the skin, silver nitrate reacts with the keratin and exposure to light to create a dark stain that cannot be washed off with water, soaps, or detergents. However, there is a distinction between who developed the formula and who manufactures it. The formula was developed by the National Physical Laboratory (NPL) in Delhi, but the ink is manufactured exclusively by Mysore Paints and Varnish Limited (MPVL), which is a Karnataka State Government undertaking. Therefore, statement 2 is incorrect. Regarding its longevity, the mark on the skin usually remains visible for 3 to 4 days as the upper layers of the skin shed, whereas the mark on the nail is much more persistent, lasting 2 to 4 weeks until the nail naturally grows out. This ensures that a voter cannot vote twice in different phases of an election occurring within a short span.

⢠Question 3 of 10 3. Question 1 points In the context of âProject Suncatcherâ, consider the following statements: It aims to deploy AI datacentres in Sun-synchronous orbits to utilize uninterrupted solar power. The project utilizes high-bandwidth inter-satellite links to process AI workloads in space. It requires a constant, high-volume data downlink to Earth for the execution of internal cluster computations. Which of the statements given above are correct? (a) 1 and 3 only (b) 2 and 3 only (c) 1 and 2 only (d) 1, 2 and 3 Correct Solution: C Project Suncatcher, an initiative by Google Research, represents a shift in addressing the massive energy demands of modern Artificial Intelligence. By placing datacentres in Low-Earth Orbit (LEO), specifically in Sun-synchronous orbits, the system can access nearly continuous solar energy without the interference of the atmosphere or the day-night cycles experienced on the ground. A critical technical feature of this project is the use of ultra-high-bandwidth inter-satellite links. Because training large AI models requires massive data exchange between processors, the project clusters satellites close together. This allows the âinternalâ heavy lifting of AI training to happen entirely in space. Consequently, the dependency on Earth bandwidth is minimized; the ground links are primarily used for sending initial inputs and receiving final outputs (inference results). This decoupling is essential because terrestrial-to-satellite bandwidth is far lower than what is required for distributed AI training. By using radiation-tolerant Tensor Processing Units (TPUs), the project seeks to move energy-intensive âcomputeâ away from terrestrial grids and water-cooling systems, thereby reducing the environmental footprint of AI. Statement 3 is incorrect because the internal cluster bandwidth is handled in space, not through Earth downlinks.

⢠Question 5 of 10 5. Question 1 points Which of the following best describes the âRadiation-hardenedâ components mentioned in the context of space-based datacentres? (a) Components coated with a thick layer of lead to block all cosmic rays. (b) Software-based firewalls that prevent data corruption from electromagnetic interference. (c) Computing systems that operate at extremely high temperatures to burn off solar radiation. (d) Specialized hardware, such as TPUs, designed to remain functional despite exposure to high-energy particles in vacuum. Correct Solution: D In the vacuum of space, particularly in Low-Earth Orbit, electronic components are subjected to ionizing radiation from cosmic rays and solar flares. Standard terrestrial hardware can suffer from âbit flipsâ or permanent physical damage when struck by high-energy particles. Project Suncatcher utilizes radiation-tolerant or radiation-hardened TPUs (Tensor Processing Units). This refers to hardware that has been specifically engineeredâeither through physical design, specialized materials, or redundant circuitryâto withstand these doses of radiation over a multi-year mission. It is not about âburning offâ radiation or using simple lead coatings (which would be too heavy for satellites); rather, it is about the intrinsic durability of the electronic architecture in a harsh environment. This allows the satellites to perform complex AI inference and training without frequent system failures.

⢠Statement 2 is incorrect; the BIS Act, 2016, establishes BIS as the National Standards Body and the primary authority for standardisation and certification. While it works with other labs, it remains the central governing body.
⢠Statement 3 is correct; the ISI mark has been the hallmark of quality in India since the 1950s. The transition to the 2016 Act was aimed at âEase of Doing Businessâ by simplifying the certification process, including fast-track licensing for MSMEs. The BIS now follows a facilitative approach, aiming to build a âquality cultureâ rather than just acting as a rigid regulator.
⢠Question 8 of 10 8. Question 1 points In the context of the 2027 Census, what does the term âSpecial Scheduleâ refer to? (a) A list of specific questions for the tribal population. (b) The electronic collection of data for the Overseas Citizens of India. (c) A separate timeline for enumeration in Ladakh and snow-bound regions. (d) A different questionnaire for the first-time voters. Correct Solution: C While the main Population Enumeration (PE) phase for the Census of India 2027 is scheduled for February 2027, certain parts of the country face extreme weather conditions. To ensure full coverage, a âSpecial Scheduleâ is implemented for Ladakh and other snow-bound regions. This allows enumeration to take place at a time when these areas are accessible, ensuring that the geographic challenges of the Himalayas do not lead to an undercount of the population.

⢠Question 9 of 10 9. Question 1 points Consider the following statements: Statement-I: The National Improvised Explosive Device Data Management System (NIDMS) is described as a ânext-generation shield against terrorism.â Statement-II: NIDMS integrates AI-enabled analytics and signature linking to detect patterns and inter-linkages between different terror attacks across India. Which one of the following is correct in respect of the above statements? (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I (c) Statement-I is correct but Statement-II is incorrect (d) Statement-I is incorrect but Statement-II is correct Correct Solution: A Statement-I is correct as the Union Home Minister recently inaugurated NIDMS, labeling it a next-generation shield because of its comprehensive digital approach to counter-terrorism. Statement-II is also correct and provides the underlying reason why NIDMS is considered such a shield. The platform is not just a storage database; it uses advanced technology to analyze signatures (like the type of timer or circuit used) and AI-based analytics to map predictive threats. The integration of these features allows investigators to move away from fragmented, paper-based files to a scientific, data-driven methodology. By linking incidents through location, device type, and explosive material, NIDMS enables law enforcement to find modus operandi trends that were previously invisible. This capability supports faster investigations and stronger legal prosecutions. Furthermore, the systemâs inter-operability with other databases like CCTNS and NAFIS ensures a unified approach to internal security. Therefore, the technological advancements mentioned in Statement-II are precisely what qualify the system as a ânext-generation shieldâ as claimed in Statement-I.
