• Question 1 of 10 1. Question 1 points Consider the following statements regarding the Technology Perspective and Capability Roadmap (TPCR-2025): One of its primary objectives is to encourage indigenisation by providing early visibility of the armed forces’ requirements to domestic industry and academia. The roadmap focuses on traditional warfare capabilities, with limited emphasis on emerging domains like cyber and space warfare. It proposes the development of universal missile launchers to enhance interoperability across all three services. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B The TPCR-2025 is a tri-services document, outlining the future technology and capability requirements for the Indian Army, Navy, and Air Force. Statement 1 is correct. A core aim of the TPCR is to act as a guide for Indian industry, academia, and research institutions. By providing early visibility of future requirements, it seeks to align domestic research and development (R&D) with military needs, thereby promoting indigenisation and self-reliance in defence. Statement 2 is incorrect. The TPCR-2025 places significant emphasis on preparing for emerging multi-domain warfare challenges. It specifically mentions the adoption of AI-enabled cyber tools, quantum communication networks, satellite-hardening measures, and High-Altitude Pseudo-Satellites (HAPS), indicating a strong focus on cyber, space, and AI-enabled conflicts. Statement 3 is correct. The document explicitly mentions the development and induction of over 500 hypersonic missiles with scramjet propulsion and universal missile launchers. This is intended to enhance strategic deterrence and, crucially, interoperability by allowing different platforms across the Army, Navy, and Air Force to use a common launcher system.

• Question 2 of 10 2. Question 1 points Which of the following best explains why a “Blood Moon” appears reddish during a total lunar eclipse? (a) The Moon’s surface is rich in iron oxides which reflect red light when Earth's shadow falls on it. (b) Light from distant red giant stars illuminates the Moon as Earth blocks direct sunlight. (c) Earth's atmosphere scatters shorter wavelength blue light away and refracts longer wavelength red light towards the Moon. (d) The phenomenon is an optical illusion caused by increased dust particles in the Moon's own tenuous atmosphere. Correct Solution: C The reddish hue of a Blood Moon is a direct consequence of Earth’s atmosphere interacting with sunlight. During a total lunar eclipse, the Earth is positioned directly between the Sun and the Moon, blocking direct sunlight from reaching the lunar surface. However, some sunlight passes through the Earth’s atmosphere at the edge (the “terminator”). This atmosphere acts like a lens, refracting or bending the light. The atmospheric phenomenon known as Rayleigh scattering, which is also responsible for Earth’s blue skies, scatters the shorter, blue wavelengths of light more effectively. The remaining longer wavelengths, primarily in the red and orange part of the spectrum, pass through the atmosphere and are refracted towards the Moon. This refracted red light illuminates the lunar surface, giving it a distinct copper or blood-red appearance. The intensity of the colour depends on the amount of dust and clouds in Earth’s atmosphere.

• Question 4 of 10 4. Question 1 points Consider the following statements about the parasite Acanthamoeba: It is a parasitic protozoan that can only survive within a human host. It exists in a dormant cyst form, which is highly resistant to environmental stressors and disinfectants. Infection is primarily caused by consuming contaminated water, leading to severe gastrointestinal illness. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: A Statement 1 is incorrect. Acanthamoeba is a free-living protozoan, meaning it can survive and reproduce independently in the environment, typically in soil and various freshwater sources like ponds, wells, and storage tanks. It does not require a human host to complete its life cycle, but it can act as an opportunistic pathogen. Statement 2 is correct. The Acanthamoeba life cycle includes two stages: the active, feeding trophozoite stage and the dormant cyst The cyst form is a key survival mechanism, as it is encased in a protective wall that makes it highly resistant to harsh conditions, including temperature extremes, desiccation, and common disinfectants like chlorine. Statement 3 is incorrect. Acanthamoeba infection does not typically cause gastrointestinal illness. It enters the body through other routes. Acanthamoeba keratitis, a severe eye infection, occurs when it enters through minor corneal tears, often associated with poor contact lens hygiene. The more fatal Granulomatous Amoebic Encephalitis (GAE) occurs when the parasite enters through open wounds or the respiratory tract and travels to the brain.

• Question 9 of 10 9. Question 1 points The likelihood of a “Blood Moon” appearing darker or having a less intense red colour during a total lunar eclipse increases if: (a) The Earth's atmosphere is exceptionally clear and free of pollutants. (b) The eclipse occurs when the Moon is at its perigee (closest to Earth). (c) There is a high concentration of volcanic ash and dust in Earth's stratosphere. (d) The eclipse takes place during a solar maximum period. Correct Solution: C The colour and brightness of a Blood Moon are directly influenced by the state of Earth’s atmosphere, as it is the medium through which sunlight is filtered and refracted onto the Moon. Option (a) is incorrect. A clearer atmosphere would allow more light, including reddish hues, to pass through, likely resulting in a brighter, more vividly coloured eclipse. Option (b) is incorrect. The Moon’s distance from Earth (perigee or apogee) affects its apparent size and the duration of the eclipse, but it does not directly determine the colour intensity. Option (c) is correct. The presence of dense particles like volcanic ash, dust, or heavy pollution in Earth’s stratosphere makes the atmosphere more opaque. This blocks more light from being refracted onto the Moon’s surface, resulting in a much darker, dimmer, and less intensely red lunar eclipse. For example, eclipses following major volcanic eruptions have been observed to be significantly darker. Option (d) is incorrect. Solar activity cycles (solar maximum/minimum) primarily affect space weather and Earth’s upper atmosphere (ionosphere/magnetosphere) but are not the primary determinant of the colour of the lunar surface during an eclipse. Incorrect Solution: C The colour and brightness of a Blood Moon are directly influenced by the state of Earth’s atmosphere, as it is the medium through which sunlight is filtered and refracted onto the Moon. Option (a) is incorrect. A clearer atmosphere would allow more light, including reddish hues, to pass through, likely resulting in a brighter, more vividly coloured eclipse. Option (b) is incorrect.

• Option (b) is incorrect. The Moon’s distance from Earth (perigee or apogee) affects its apparent size and the duration of the eclipse, but it does not directly determine the colour intensity.

• Option (c) is correct. The presence of dense particles like volcanic ash, dust, or heavy pollution in Earth’s stratosphere makes the atmosphere more opaque. This blocks more light from being refracted onto the Moon’s surface, resulting in a much darker, dimmer, and less intensely red lunar eclipse. For example, eclipses following major volcanic eruptions have been observed to be significantly darker.

• Option (d) is incorrect. Solar activity cycles (solar maximum/minimum) primarily affect space weather and Earth’s upper atmosphere (ionosphere/magnetosphere) but are not the primary determinant of the colour of the lunar surface during an eclipse.

Chidambaranar, who was a prominent freedom fighter known for establishing the first indigenous Indian shipping service. The port is one of India’s 13 major ports and plays a significant role in coal and container handling for South India. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Statement 1 is incorrect. VOC Port is located in Tuticorin, Tamil Nadu, on the Coromandel Coast along the Bay of Bengal, not the Malabar Coast (which is on the western side of India along the Arabian Sea). Its location is strategic for trade routes in the Bay of Bengal and the wider Indian Ocean. Statement 2 is correct. The port, formerly known as Tuticorin Port, was renamed in 2011 to honour O. Chidambaranar. He is celebrated as “Kappalottiya Tamizhan” (The Tamil Helmsman) for launching the Swadeshi Steam Navigation Company in 1906 to compete against the British monopoly in shipping, a significant act of economic resistance during the freedom struggle. Statement 3 is correct. VOC Port is classified as one of India’s 13 major ports, which are administered by the central government. It is a critical maritime hub for Southern India, with major operations in handling coal for thermal power plants, container movement, and other general cargo.
