Q3582. Which of the following statements regarding the classification of land for revenue purposes is correct?
Explanation
The medieval revenue system was flexible, recognizing that not all land could yield a profit.

Q3583. In the context of Chola temple architecture, what does the term ‘Gopuram’ specifically refer to?
Explanation
In South Indian temple architecture, particularly during the Chola and later periods, the Gopuram refers to the towering entrance gateway located at the perimeter of the temple complex.

Q3584. Which principle of Judicial Restraint prevents the courts from ruling on an issue unless it is absolutely necessary to resolve an actual dispute?
Explanation
The Doctrine of Mootness is a principle of judicial restraint where a court declines to decide a case because the issues involved are no longer live or have already been resolved. Courts avoid ruling on abstract or hypothetical questions where a judgment would have no practical effect on the parties involved. This ensures that judicial resources are focused on actual, ongoing disputes.

Q3585. Consider the following statements: Statement I: The Cape of Good Hope sea route experienced a significant permanent decline in total maritime traffic following the opening of the Suez Canal. Statement II: Modern supertankers transporting crude oil often use the Cape of Good Hope route to bypass the dimensional and draft restrictions of the Suez Canal. Which of the following is correct?
Explanation
The opening of the Suez Canal led to a decline in traffic around the Cape of Good Hope as ships sought shorter routes. However, the Cape route remains essential for modern supertankers that are too large or have too deep a draft to pass through the Suez Canal. While both statements describe real trends, the continued use by supertankers is an operational necessity.
