Q471. The following question consists of two statements, Assertion (A) and Reason (R). Choose the correct option. Assertion (A): The Paris Agreement marks a shift from the Kyoto Protocol by requiring all countries, rather than just developed ones, to submit emissions reduction targets. Reason (R): Under the Paris Agreement, targets are determined bottom-up through Nationally Determined Contributions (NDCs) rather than being imposed top-down.
Explanation
The Paris Agreement represents a significant evolution in international climate policy. While the Kyoto Protocol only set mandatory targets for developed countries, the Paris Agreement involves all nations. It utilizes a "bottom-up" approach where each country determines its own targets through Nationally Determined Contributions. This flexible framework encourages broader participation and allows countries to set goals that reflect their unique economic and social realities.

Q472. Materials that offer zero electrical resistance at extremely low temperatures are called:
Explanation
Superconductors are unique materials that exhibit exactly zero electrical resistance when cooled below a specific critical temperature. In this state, they can carry electric current indefinitely without any loss of energy as heat. This phenomenon also allows them to expel magnetic fields, a property known as the Meissner effect, which has significant applications in advanced technologies like magnetic levitation and medical imaging.

Q473. The following question consists of two statements, Assertion (A) and Reason (R). Select the correct answer using the codes given below: Assertion (A): Gilund is considered a major regional center of the Ahar culture rather than a simple village. Reason (R): It features extensive structural complexes, including parallel walls and significant storage facilities indicative of a complex economy.
Explanation
Gilund is recognized as a major regional center because of its impressive archaeological profile. The presence of extensive structural complexes, including massive parallel walls and sophisticated grain storage pits, points to a highly organized and complex economy. These features suggest that Gilund functioned as a central place for resource management and administration within the broader Ahar-Banas cultural network in southeastern Rajasthan.

Q474. The presence of a dockyard and a warehouse at Lothal, combined with the discovery of Persian Gulf seals in the city, strongly indicates that Lothal was:
Explanation
The combination of a specialized dockyard, large storage warehouses, and foreign artifacts like Persian Gulf seals conclusively identifies Lothal as a major maritime trade hub. It served as a vital link between the Indus Valley and other ancient civilizations across the Arabian Sea. This role as an international port was central to Lothal’s economy and its overall historical significance.
RAS PrelimsIndian Polity and Governance · Framing of the Constitution, Preamble and Citizenship
Q475. Consider the following statements regarding the constitutional provisions for citizenship at the commencement of the Constitution: I. A person domiciled in India and born in the territory of India became a citizen. II. A person migrating from Pakistan to India before July 19, 1948, became a citizen under certain conditions. III. A person who migrated to Pakistan after March 1, 1947, and never returned lost Indian citizenship. IV. A person of Indian origin residing outside India could register as a citizen. V. Any person acquiring foreign citizenship voluntarily was deemed an Indian citizen until 1955. Which of the above combination of statements is incorrect?
Explanation
Statement V is incorrect because according to Article 9, any person who voluntarily acquired the citizenship of a foreign state ceased to be an Indian citizen immediately. This rule applied from the commencement of the Constitution and was not deferred until 1955. The other statements correctly describe the various categories of persons who became citizens at the time of India becoming a Republic.
Q476. Which of the following is the most appropriate statement regarding the economic significance of the Thar Desert for Rajasthan?
Explanation
The Thar Desert holds immense economic potential for the state of Rajasthan. Its vast, open landscapes and high solar radiation make it ideal for large-scale solar and wind energy projects. Furthermore, the region is rich in mineral wealth, including significant deposits of limestone, gypsum, and hydrocarbons like oil and natural gas. These resources are vital for industrial growth and state revenue generation.

Q477. Arrange the following major global environmental agreements in correct chronological order of their adoption: I. Paris Agreement II. Kyoto Protocol III. United Nations Framework Convention on Climate Change (UNFCCC) adoption at Rio Which of the following represents the correct sequence?
Explanation
The international climate regime began with the adoption of the UNFCCC at the Rio Earth Summit in 1992. This was followed by the Kyoto Protocol in 1997, which set the first specific emission reduction targets. Finally, the Paris Agreement was adopted in 2015, creating a new universal framework for climate action. This sequence shows the gradual strengthening of global commitments to address the threat of global warming.

Q478. Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Silver is not used for making standard electrical transmission wires despite being the best conductor of electricity. Reason (R): Silver is highly expensive and prone to theft compared to copper and aluminum.
Explanation
Silver is the most efficient conductor of electricity due to its high electron mobility. However, it is not used for large-scale power transmission because its high cost makes it economically unfeasible. Copper and aluminum offer a better balance of high conductivity, lower cost, and abundance. Additionally, using silver would significantly increase the risk of theft from utility infrastructure due to its value.

Q479. The Ganeshwar civilization, known for its rich copper artifacts, is situated on the banks of which seasonal river?
Explanation
The Ganeshwar civilization, a crucial center of early metallurgy, flourished on the banks of the Kantli river in the Sikar district. This seasonal river provided essential water for the community and its smelting activities. The site’s location was highly strategic, being situated near the rich copper ores of the Khetri belt, which allowed it to become a primary copper supplier.
RAS PrelimsIndian Polity and Governance · Framing of the Constitution, Preamble and Citizenship
Q480. Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The Indian Constitution provides for only a single citizenship, that is, the Indian citizenship. Reason (R): Article 9 states that no person shall be a citizen of India if he has voluntarily acquired the citizenship of any foreign state.
Explanation
India maintains a system of single citizenship to promote national unity. The Constitution does not recognize dual citizenship. Article 9 reinforces this by stating that anyone who voluntarily acquires foreign citizenship automatically loses their Indian citizenship. This ensures that an Indian citizen owes allegiance only to the Union of India, unlike federal systems like the United States where dual citizenship exists.
