Question No. 1
Consider the following statements:
1.The Organisation for the Prohibition of Chemical Weapons (OPCW) is the Hague-based implementing body for the Chemical Weapons Convention, to which India is a signatory and state party.
2.The Biological Weapons Convention (BWC) functions as the first multilateral disarmament treaty banning an entire category of Weapons of Mass Destruction (WMD), and its provisions have been both signed and ratified by India.
3.The Nuclear Suppliers Group (NSG) is a 48-member export-control body that admitted India as a full member following its signing of the Nuclear Non-Proliferation Treaty (NPT).
Which of the statements given above are correct?
Question No. 2
Consider the following statements regarding international nuclear frameworks:
1.The 1996 Comprehensive Test Ban Treaty (CTBT) bans all nuclear explosions for both military and peaceful purposes, but it has not officially entered into force because it lacks necessary ratifications from states like India, Pakistan, North Korea, and the United States.
2.The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) is a landmark agreement aimed at preventing the spread of nuclear arms, promoting peaceful nuclear energy cooperation, and pursuing disarmament, and India was one of its primary founding signatories.
3.The Treaty on the Prohibition of Nuclear Weapons (TPNW), which entered into force on January 22, 2021, prohibits state parties from developing, testing, or stockpiling nuclear explosive devices, and India has chosen neither to sign nor ratify it.
Which of the statements given above are correct?
Question No. 3
Consider the following statements regarding Directed Energy Weapons:
1.High-Energy Lasers operate as non-kinetic precision weapons that concentrate intense electromagnetic energy to melt, blind, or cause structural failure in targets at the speed of light.
2.Under the domestic DURGA-II project, the Defence Research and Development Organisation (DRDO) is actively developing a conventional rocket-propelled kinetic interceptor shield to detonate artillery shells in mid-air.
Which of the statements given above is/are correct?
Question No. 4
Which of the following presents the correct chronological arrangement of different types of coal ordered from the HIGHEST carbon concentration percentage to the LOWEST carbon concentration percentage?
Question No. 5
Consider the following statements:
1.Coke is a tough, porous, black, nearly pure carbon material manufactured through the destructive distillation of coal, which involves heating it at high temperatures in an completely oxygen-free chamber.
2.Fly ash is a fine particulate byproduct generated by coal-fired thermal power plants that cannot be integrated into building materials or blended with standard Portland cement due to structural breakdown risks.
Which of the statements given above is/are correct?
Question No. 6
Consider the following statements regarding fuel gases utilized in domestic and transport sectors:
1.Liquefied Petroleum Gas (LPG) is a flammable hydrocarbon mixture consisting primarily of propane, butane, and isobutane, containing added ethyl mercaptan to give it a distinct odor for rapid leak detection.
2.Compressed Natural Gas (CNG) consists primarily of methane stored under high pressure, serving as a lower-emission, cleaner-burning alternative to gasoline and diesel engines.
3.Within the extraction industry, sweet gas denotes natural gas processing lines that are free from or contain very low concentrations of toxic, corrosive hydrogen sulfide, whereas sour gas contains significant amounts of it.
Which of the statements given above are correct?
Question No. 7
Based on industrial combustion data, which of the following sequences accurately lists the fuels in descending order based on their standard Calorific Value (from HIGHEST heat output per unit mass to the LOWEST)?
Question No. 8
Consider the following statements regarding solar energy harvesting technologies:
1.Solar Photovoltaic (PV) panels generate electricity directly from solar radiation using semiconductor cells, making them suitable for residential and commercial electrical grids.
2.Solar thermal panels absorb sunlight to heat a working fluid, capturing thermal energy directly for applications such as space heating or domestic hot water systems rather than direct electrical conversion.
Which of the statements given above is/are correct?
Question No. 9
Consider the following statements regarding solar-powered water pumping systems:
1.A solar water pumping system integrates an electric pump with a solar photovoltaic (PV) array that harvests sunlight to generate the necessary driving power.
2.These solar-powered arrays can run a variety of pump configurations, including surface pumps, deep-well submersible units, Direct Current (DC) motor systems, Alternating Current (AC) induction motors, centrifugal setups, and positive-displacement piston pumps.
Which of the statements given above is/are correct?
Question No. 10
Consider the following statements regarding the strategic objectives highlighted in the National Geothermal Energy Policy:
1.The policy targets unlocking an estimated 10,600 MW potential of clean geothermal energy to provide dependable, continuous base-load power to the national grid.
2.To encourage exploration, the policy allows up to 100% Foreign Direct Investment (FDI) via automatic routes alongside fiscal incentives like tax holidays, green bonds, and viability gap funding (VGF).
3.To protect long-term capital investments, supported geothermal extraction projects are granted an absolute maximum commercial lease tenure of 5 years, with zero extensions allowed.
Which of the statements given above are correct?
