Atmospheric precipitation becomes acidic when certain gases react with water, oxygen, and other chemicals.

These acids then fall to the ground as rain, snow, or fog, damaging forests and aquatic ecosystems.

Q3504. In the Chola administrative system systematically reorganized by Rajaraja I, the term ‘Valanadu’ referred to which of the following?
Explanation
During the administrative reorganization under Rajaraja I, the Chola empire was structured into several tiers for efficient governance. The largest unit was the Mandalam (province). To improve local oversight, several Nadus (districts) were grouped together to form a larger territorial unit called a Valanadu. This intermediary division helped the central government manage revenue collection and local administration more effectively across the diverse regions of the expanding Chola state.

Q3505. Given below are two statements: Statement I: The Supreme Court has held that truth is a valid defence in contempt proceedings.

Which one of the following is correct in respect of the above statements?
Explanation
Previously, truth was not an accepted defense in contempt proceedings. However, following the 2006 amendment to the Contempt of Courts Act, 1971, the law explicitly allows truth as a valid defense. This is applicable only if the statement is made in the public interest and is bona fide. This change ensures that honest and justified criticism is not unfairly penalized.

Q3506. Consider the following statements: Statement I: Canals are constructed artificial waterways used for navigation and irrigation, often linking navigable rivers or lakes. Statement II: The construction of locks in canal systems is entirely unnecessary if the canal passes over uneven terrain. Which of the following is correct?
Explanation
Canals are man-made waterways designed for navigation, often interconnecting natural bodies of water. When a canal must cross uneven terrain or handle differences in water levels, the construction of locks is essential. Locks act as water elevators, raising or lowering vessels to match the elevation of the next section of the waterway. Without them, navigation across varying heights would be physically impossible.
