Q2471. Consider Statement I and Statement II regarding State finances. Statement I: State excise on liquor and petroleum products are crucial for State finances because they are outside the GST framework. Statement II: States frequently alter the Value Added Tax (VAT) on petrol and diesel to manage sudden revenue shortfalls.
Explanation
Because liquor and petroleum products are currently outside the GST, they remain vital for state fiscal autonomy. States can independently adjust excise duties and VAT on these items to respond to revenue needs. This flexibility is particularly useful during economic downturns or when there are sudden gaps in the state budget, allowing for immediate and localized fiscal adjustments.

Q2472. Overhanging, single-stranded ends of DNA created by certain restriction enzymes are called:
Explanation
Sticky ends are short, single-stranded overhanging sequences of DNA produced when certain restriction endonucleases cut the double helix in a staggered fashion. These ends are called sticky because they can easily form complementary hydrogen bonds with other DNA fragments cut by the same enzyme. This temporary base-pairing significantly facilitates the subsequent action of DNA ligase, making the cloning process much more efficient and reliable.

Q2477. Which of the following is NOT a major challenge to expanding a State’s own tax revenue base?
Explanation
Expanding a state’s own tax base is challenging due to the large informal economy and political reluctance to tax sectors like agriculture. Furthermore, GST has limited the range of goods and services that states can tax independently. However, central devolution is designed to supplement, not replace, state efforts, and the Finance Commission even uses tax effort as a criterion to reward states for revenue efficiency.

Q2480. Which of the following is considered the most appropriate cultural consequence of the repeated foreign invasions (Indo-Greeks, Sakas, Parthians, Kushanas) during the Post-Mauryan period?
Explanation
The repeated invasions by groups like the Indo- Greeks, Sakas, and Kushanas did not lead to the destruction of Indian culture. Instead, these groups were gradually assimilated into Indian society, often adopting Indian names, languages, and religions. This process of Indianization resulted in a vibrant composite culture, evidenced by syncretic art styles and the introduction of new elements in coinage, technology, and advanced astronomy.
