Q1511. Match List I (Biome) with List II (Dominant Soil Order/Type) and select the correct answer using the codes given below.
Biome
Dominant Soil Order/Type
A. Tropical Rainforest
i. Spodosol (Podzol)
B. Temperate Grassland
ii. Gelisol (Permafrost soils)
C. Boreal Forest (Taiga)
iii. Oxisol (Lateritic soils)
D. Tundra
iv. Mollisol (Chernozem) Options:
Explanation
Biomes are associated with specific soil types formed by local climate and vegetation. Tropical rainforests have heavily leached Oxisols, while temperate grasslands possess fertile Mollisols. Boreal forests are characterized by acidic Spodosols created by needle decay. In the cold tundra, Gelisols predominate, featuring a permafrost layer that restricts drainage and limits the development of distinct soil profiles and horizons.

Q1512. An economy is facing a severe recession with high unemployment. Which combination of policies is most appropriate to combat this situation?
Explanation
To combat a recession, a dual approach of increasing the money supply and boosting government spending is most effective. Lowering interest rates encourages private borrowing and investment, while increased public expenditure and tax cuts stimulate aggregate demand directly. Together, these policies work to increase production, create employment opportunities, and restore economic growth during periods of significant slowdown and high unemployment.

Explanation
This long-range ballistic missile is designed to carry a substantial warhead to distant targets. Its payload capacity of approximately fifteen hundred kilograms allows for the integration of various types of strategic warheads, including nuclear configurations. This weight capacity ensures that the missile can deliver a powerful strike across intercontinental distances, maintaining a credible deterrent while utilizing its advanced three-stage solid propulsion and guidance systems.

Q1514. Consider the following Assertion (A) and Reason (R) and select the correct answer from the options given below: Assertion (A): The ancient site of Ahar is also known as Tambavati in regional traditions. Reason (R): Extensive evidence of copper smelting furnaces and copper tools has been discovered at the Ahar archaeological site.
Explanation
Ahar is traditionally known as Tambavati because of its historical connection with copper. Archaeological excavations at the site have yielded extensive evidence of copper smelting furnaces, slag, and a wide variety of copper tools. This metallurgical activity was the backbone of the local economy, making the name Tambavati an accurate description of the site’s role as a major copper center.

It directs the State to safeguard the forests and wildlife of the country. III. It was added to the Constitution by the 44th Amendment Act. Which of the above statement(s) is/are correct?
Explanation
Article forty-eight-A directs the state to protect and improve the environment and to safeguard the forests and wildlife of the country. This provision was added by the forty-second amendment act of nineteen seventy-six, not the forty-fourth. It reflects the constitutional commitment to ecological preservation, recognizing that a healthy environment is vital for the well-being of the nation and its citizens.
RAS PrelimsWorld Geography · Natural Vegetation and Biomes
Q1517. Consider the following adaptations observed in desert vegetation (xerophytes): I. Extensive, shallow root systems to rapidly absorb occasional rainfall. II. Transformation of leaves into spines to reduce transpiration and deter herbivores. III. Sunken stomata that open primarily during the day to maximize photosynthesis. IV. Presence of thick, fleshy stems to store water. V. Shedding of leaves during dry periods to conserve moisture. Which of the above statement(s) is/are incorrect?
Explanation
Desert vegetation uses various adaptations to manage water stress. These include thick stems for storage and spines to reduce transpiration. While many plants have shallow roots for quick absorption, others have deep taproots. However, having stomata that open during the day is not an adaptation for water conservation; instead, many desert plants open stomata at night to prevent moisture loss.
RAS PrelimsIndian Economy · Monetary and Fiscal Policy, Union Budget and Resource Mobilisation
Q1518. Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R). Assertion (A): Expansionary fiscal policy can sometimes lead to demand-pull inflation. Reason (R): Increased government spending and tax cuts boost aggregate demand, which can outpace aggregate supply.
Explanation
Increasing government expenditure and reducing taxes significantly boosts the purchasing power of consumers. When this rise in aggregate demand occurs faster than the economy’s ability to produce goods and services, it leads to upward pressure on prices. This specific type of inflation occurs because the total spending in the economy exceeds the available supply, illustrating a common economic trade-off.

Q1519. In the context of India’s recent test of the Agni-V missile (Mission Divyastra), what does the application of MIRV technology enable?
Explanation
This advanced technology allows a single ballistic missile to deploy several independent re-entry vehicles during its flight. Each vehicle can be programmed to hit a separate geographic location, significantly complicating the task for enemy missile defense systems. By increasing the number of targets engaged per launch, it enhances the effectiveness and saturation capability of the strategic deterrent, ensuring higher survivability of the strike.
