Answer:  Option C - Second law

Explanation:

• The second law of thermodynamics states that in a closed system, entropy (disorder) always increases over time.
• This means that any system will naturally tend towards a state of less usable energy.
• Perpetual motion machines, by definition, would violate this principle by continuously producing work without any input or loss of energy.

Answer:  Option A - Karnataka

Explanation:

• Miniopterus srinii, a new species of bent-winged bat, was discovered in Karnataka.
• This discovery highlights Karnataka's biodiversity richness and underscore the state's significance in scientific research and conservation efforts.
• The identification of Miniopterus srinii contributes to understanding regional species diversity and ecological dynamics, emphasizing the importance of continued biodiversity surveys and conservation initiatives in the region.

Answer:  Option D - Graphite

Explanation:

• Graphite is commonly used as an electrode in supercapacitors due to its high surface area and excellent conductivity, which are crucial for storing and releasing energy efficiently.
• The structure of graphite allows for rapid ion movement, enhancing the capacitor's performance.
• This material enables supercapacitors to achieve high capacitance values and rapid charge-discharge cycles, making them ideal for applications requiring quick bursts of power or energy storage.

Answer:  Option B -  42nd Amendment Act

Explanation:

• The 42nd Constitutional Amendment Act (1976) transferred education from the State list to the Concurrent list, enabling both the central and state governments to legislate on educational matters.
• This shift was recommended by the Swaran Singh Committee during the Emergency to ensure uniform national policies.
• The amendment was implemented amid controversy, with critics arguing it curtailed state autonomy over educational policies and was passed swiftly without extensive parliamentary debate.

Answer:  Option B - Promoting evidence-based decision-making

Explanation:

• The eSankhyiki portal, launched by MoSPI, aims to improve accessibility and usability of official statistics for planners, policymakers, researchers, and the public.
• It catalogs major data assets like National Accounts Statistics and Consumer Price Index, enabling easy search and download functionalities.
• The portal aligns with global statistical practices, facilitating evidence-based decision-making by providing real-time inputs and comprehensive data management capabilities.
