Q2323. Consider the following statements about irrigated farming: I. It has significantly increased agricultural productivity in arid and semi-arid regions. II. Over-irrigation without proper drainage leads to waterlogging. III. Canal irrigation can cause an increase in soil salinity through capillary action. IV.

Explanation
The introduction of GST led to the subsuming of several indirect taxes. Most notably, the State-level Value Added Tax on the sale of goods was integrated into the new regime.

Q2327. Which of the following geographic regions was definitely NOT under the political control of the Kushana Empire at its zenith?
Explanation
At its peak, the Kushana Empire was a vast transcontinental power covering Bactria, Gandhara, and much of Northern India, including Mathura. However, its political authority did not extend to Tamilakam, the southern tip of the Indian peninsula. That region remained under the independent control of the Sangam dynasties--the Cheras, Cholas, and Pandyas. The Kushana influence in the South was limited to indirect commercial ties rather than direct political or military administration.
