Explanation
The concept of the Concurrent List in the Indian Constitution was inspired by the Australian Constitution, not the Irish one. This list allows for joint legislative authority, where central laws generally prevail over state laws in case of conflict.

Q3914. When a forest is cleared for agriculture, a significant amount of carbon is released into the atmosphere. This carbon originates primarily from which two components of the forest ecosystem?
Explanation
Forest ecosystems store carbon primarily in living biomass, including trunks, branches, and roots, and in the organic matter of the soil. When land is cleared for agriculture, these stores are disturbed. Burning vegetation releases carbon instantly, while soil disturbance leads to the decomposition of organic matter. These processes contribute significantly to the overall atmospheric concentration of carbon dioxide.

Q3918. Under which Article of the Constitution of India are the ‘Residuary Powers of Legislation’ vested in the Parliament?
Explanation

This provision strengthens the central government, ensuring it can address new and unforeseen legislative requirements.
Q3919. Which of the following represents the correct chronological sequence of the establishment or adoption of these major environmental milestones?

The United Nations Framework Convention on Climate Change was then adopted in 1992 at the Rio Earth Summit. Finally, the Paris Agreement was established in 2015, representing the modern era of climate action.
