RAS PrelimsIndian Polity and Governance · Parliament: Lok Sabha and Rajya Sabha
Q2911. Read the following statements regarding joint sittings carefully: Statement I: If the President has notified his intention to summon a joint sitting, the bill does not lapse even if the Lok Sabha is dissolved subsequently. Statement II: A joint sitting is governed by the Rules of Procedure of the Rajya Sabha. Which of the above statement(s) is/are correct?
Explanation
If the President notifies the intention to summon a joint sitting, the bill survives even if the Lok Sabha is dissolved later. This ensures that the legislative effort is not wasted due to the House’s dissolution. However, joint sittings are governed by the Rules of Procedure of the Lok Sabha, not the Rajya Sabha. Therefore, only the first statement is correct.

Q2912. Identify the odd one out. Which of the following is NOT typically classified as an "emerging industrial economy" in modern economic geography, but rather as an early-industrialized developed economy?
Explanation
Emerging industrial economies like India, Brazil, and nations in Southeast Asia are currently undergoing rapid manufacturing growth and structural shifts. These regions are expanding their global production shares through industrialization. Conversely, the United Kingdom is a developed economy that experienced its industrial revolution much earlier. It is now characterized by a mature service sector and high-value manufacturing rather than emerging industrial status.
Q2913. Read the following statements regarding the composition of fish production in India and select the correct answer from the options given below: Statement I: Historically, marine fisheries constituted the major share of India’s total fish production. Statement II: In recent years, inland fisheries (including aquaculture) have surpassed marine fisheries and now contribute to more than 70 percent of total fish production.
Explanation
Historically, marine fisheries provided the largest share of India’s total fish production. However, recent decades have seen a significant structural shift. Inland fisheries, which include freshwater aquaculture, have grown exponentially and now surpass marine catches. Today, inland fisheries contribute more than seventy percent of the total fish production, reflecting the high potential of pond and reservoir-based farming in rural areas.

Q2914. Calcium deficiency in older adults can lead to a condition characterized by fragile and porous bones known as:
Explanation
Osteoporosis is a skeletal condition characterized by decreased bone mass and the deterioration of bone tissue, making them fragile and highly susceptible to fractures. While it can affect anyone, it is particularly common in older adults due to long-term calcium deficiency and hormonal changes. Ensuring adequate intake of calcium and Vitamin D throughout life is essential for maintaining strong bone density.

Q2915. Which of the following was the most direct negative consequence of the Subsidiary Alliances (1817-1818) on the internal dynamics of the Rajput states?
Explanation
The Subsidiary Alliances with the British led to the breakdown of traditional feudal structures within Rajput states. Rulers, now protected by British military power, no longer depended on the loyalty and military support of their feudal nobles. This shifted the internal balance of power, often leading to autocracy by the rulers and resentment among the nobility, ultimately weakening the indigenous political system.
RAS PrelimsAncient Indian History · Gupta Empire and Post-Gupta Period
Q2916. Which of the following provides the best explanation for the shift from gold coins to copper and cowrie shells in everyday transactions during the post-Gupta period?
Explanation
The transition from high-value gold coins to copper and cowrie shells for daily transactions in the post-Gupta period was largely due to economic changes. Long-distance maritime and overland trade had declined, leading to the rise of self-sufficient village economies. This reduced the need for a highly monetized exchange system, as local needs were increasingly met through barter or low-value currency within decentralized regions.

Q2918. Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R): Assertion (A): Modern oil refining industries are increasingly located near consumer markets or major port cities rather than directly at the oil fields. Reason (R): Transporting crude oil by pipeline or tanker is generally cheaper and technically easier than transporting multiple, specialized refined petroleum products. In the context of the above two statements, which one of the following is correct?
Explanation
Modern oil refineries are frequently built near large consumer markets or major ports to improve distribution efficiency. It is technically simpler and more cost-effective to transport large volumes of crude oil via pipelines or massive tankers than to move various specialized refined products separately. Locating refineries near markets ensures that finished products can be delivered quickly to consumers with lower transport costs.
Q2919. The following question consists of two statements, one labeled as Assertion (A) and the other as Reason (R). Examine these two statements carefully and select the correct answer from the options given below: Assertion (A): The Blue Revolution focuses exclusively on enhancing fish catch from deep-sea marine environments. Reason (R): Inland aquaculture has experienced exponential growth and is highly suitable for integration with agriculture in rural areas.
Explanation
The Blue Revolution does not focus exclusively on deep-sea marine environments; in fact, it places immense emphasis on inland fisheries and aquaculture. While marine resources are important, inland aquaculture has experienced the most rapid growth in recent years. This is because inland farming is highly suitable for integration with existing agricultural activities in rural areas, providing farmers with additional income.

Q2920. A balanced diet must contain carbohydrates, proteins, and fats ideally in a specific ratio. The general recommended energy contribution ratio from carbohydrates, proteins, and fats respectively is closest to:
Explanation
A balanced diet requires a specific distribution of energy from the three primary macronutrients. General nutritional guidelines suggest that carbohydrates should provide the majority of daily calories, followed by fats, with proteins contributing the remaining portion. This ratio ensures that the body receives sufficient fuel for energy, essential fatty acids for cellular health, and amino acids for tissue repair and growth.
