RPSC RAS Prelims 2008 Question Paper with Answers & Explanations

Explanation

The Gandhara school of art, which flourished primarily during the Kushana period under the patronage of King Kanishka, is the most prominent example of the fusion between Indian and Greek artistic traditions. Often referred to as Graeco-Buddhist art, it utilized Hellenistic techniques and aesthetic standards to depict Buddhist themes. The sculptures in this style typically represent the Buddha and Bodhisattvas with physical features borrowed from Greek mythology, such as the athletic physique, wavy hair, and heavy, folded drapery reminiscent of the Roman toga or Greek chiton. This school thrived in the northwestern frontier of the Indian subcontinent, where the influence of the Indo-Greeks remained strong even after their political decline.

Explanation

The Ramasnehi sect was founded by Sant Ramcharan ji in the 18th century, and Shahpura in the Bhilwara district serves as its principal religious seat or Mukhya Peeth. Sant Ramcharan ji shifted to Shahpura from the Jaipur region and established this center to promote a path of devotion centered on the chanting of the name of Ram, emphasizing a formless or Nirguna divine. The sect is characterized by its followers wearing pink robes and strictly adhering to vegetarianism and meditation. The most significant event associated with this ashram is the Phuldol Mahotsav, an annual festival celebrated with great fervor immediately following the festival of Holi, marking the spiritual legacy of the sect at its headquarters in Shahpura.

Explanation

Kgalema Motlanthe was elected by the South African National Assembly to serve as the President of South Africa on September 25, 2008. His appointment followed the resignation of Thabo Mbeki, who stepped down after being formally recalled by the National Executive Committee of the African National Congress (ANC). Motlanthe served as an interim president to ensure executive continuity and political stability until the general elections in May 2009.

Explanation

Dark adaptation is the comprehensive physiological process by which the human eye increases its sensitivity to low levels of illumination following exposure to bright light. This process involves two primary mechanisms that occur over time. Initially, the pupils dilate to maximize the amount of light entering the eye. Simultaneously, a biochemical change occurs in the retina where the photopigment rhodopsin, located in the rod cells, begins to regenerate. In brightly lit conditions, rhodopsin is bleached or broken down, rendering the rods temporarily inactive. Upon entering a dark environment, the rods must synthesize new rhodopsin to enable scotopic or low-light vision. Because this chemical resynthesis and the subsequent increase in retinal sensitivity are not instantaneous, the eye requires a period of adjustment before objects in a dark room become visible.

Explanation

Gagron Fort, located in the Jhalawar district of Rajasthan, is the most celebrated example of a Jal Durg or water fort in India. It is uniquely situated at the confluence of the Ahu and Kali Sindh rivers, which surround the structure on three sides, creating a formidable natural moat. Built on a solid rocky hill without a formal foundation, the fort utilizes the surrounding water bodies and the rugged landscape of the Mukundara hills for its defense. Historically, it served as a strategic stronghold in the Hadoti region and perfectly embodies the characteristics of a water-protected fortress as described in ancient Indian treatises on military architecture.

Explanation

The Kumbhalgarh inscription, dated 1460 AD, is engraved on five stone slabs and serves as a vital historical record for the history of Mewar and the reign of Maharana Kumbha. It contains a detailed genealogy starting from Guhil and provides a comprehensive description of Kumbha military victories against the rulers of Malwa and Gujarat. The inscription also sheds light on the Maharana personal character, his scholarly pursuits, and his architectural contributions, specifically the construction of the Kumbhalgarh fort. It serves as an authentic source for understanding the social, religious, and political environment of 15th-century Rajasthan.

Explanation

Ann Elizabeth Dunwoody made history on November 14, 2008, when she was promoted to the rank of four-star general in the United States Army, becoming the first woman in the history of the U.S. military to achieve this rank. She served as the commander of the U.S. Army Materiel Command, which is responsible for the global supply chain, maintenance, and logistics of the force. Having been commissioned as a second lieutenant in 1975, her promotion marked a significant milestone for women in the armed forces, as she reached the highest attainable rank in the military during peacetime.

Explanation

The Brahmo Samaj, Ramakrishna Mission, and Arya Samaj were established as socio-religious reform movements rather than political entities. Their primary focus was on the spiritual and social upliftment of Indian society through the eradication of superstitions, social inequalities, and the promotion of education. Although they did not engage in active politics, their teachings and activities played a crucial role in creating a sense of national identity and cultural pride. By emphasizing the greatness of Indian heritage and the necessity of social reform, these organizations provided the moral and intellectual framework that fostered a spirit of patriotism and prepared the ground for the subsequent political movements for independence. Swami Dayanand Saraswati of the Arya Samaj, for instance, was among the first to use the term Swaraj, while Swami Vivekananda's call for a strong, self-reliant India inspired generations of nationalist leaders.

Explanation

The National Water Development Agency (NWDA) was established in July 1982 by the Government of India as an autonomous society under the Societies Registration Act, 1860. It functions under the Ministry of Jal Shakti. The agency was created following the formulation of the National Perspective Plan for Water Resources Development in 1980, which recommended the inter-linking of rivers to transfer surplus water from certain basins to water-deficient regions. The NWDA conducts surveys, investigations, and feasibility studies for these river-interlinking projects. The actual founding year of 1982 is not available among the given options. The year 1980, which corresponds to the National Perspective Plan that directly led to the creation of the NWDA, is the closest available option.

Explanation

Kandhamal is a district situated in the central part of the state of Odisha. It was created as a separate administrative district in 1994 when the former Phulbani district was subdivided. The region is predominantly hilly and forested, inhabited by a large population of tribal communities such as the Kandhas. In 2008, the district gained significant national and international attention due to widespread communal unrest following the assassination of a local religious leader. Beyond its administrative and social history, the area is geographically notable for its high altitude and unique climatic conditions, which facilitate the cultivation of the organic Kandhamal Haldi, a specific variety of turmeric indigenous to the district.

Explanation

Paradip Port is a premier major port of India located in the Jagatsinghpur district of Odisha. It is an artificial, deep-water port situated at the confluence of the Mahanadi River and the Bay of Bengal. Commissioned in 1966, it was the first major port on the East Coast to be developed after independence. The port serves as a critical gateway for the maritime trade of Eastern India, handling significant volumes of bulk cargo such as iron ore, thermal coal, and crude oil, largely due to its strategic location near the mineral-rich belts of the Odisha hinterland.

Explanation

RIDCOR stands for Road Infrastructure Development Company of Rajasthan Limited. It was incorporated in 2004 as a joint venture between the Government of Rajasthan and Infrastructure Leasing and Financial Services Limited (IL&FS), with both parties holding equal equity. The company was established specifically to implement the Mega Highways Project, which focuses on developing, improving, and maintaining high-quality road corridors across the state through a public-private partnership model to foster economic development and connectivity.

Explanation

The Mehkama Bakayat was an administrative department established within the princely states of Rajasthan to oversee the settlement of financial liabilities. Its primary function was to manage the liquidation of outstanding debts and arrears owed by the ruler. The department ensured that the king's various financial obligations, whether related to personal expenses or state-related procurement, were systematically accounted for and paid. By centralizing the repayment of these dues, the Mehkama Bakayat helped maintain the fiscal reputation and administrative efficiency of the state’s treasury.

Explanation

The rate of cooling of a body is governed by the Stefan-Boltzmann Law, which states that the rate of heat loss dQ/dt is proportional to the difference between the fourth powers of the absolute temperatures of the body and its surroundings: dQ/dt = σeA(T⁴ - Tₛ⁴). This expression can be factored using the algebraic identity a⁴ - b⁴ = (a - b)(a + b)(a² + b²), resulting in dQ/dt = σeA(T - Tₛ)(T + Tₛ)(T² + Tₛ²).

In both Churu and Shimla, the initial temperature difference (T - Tₛ) between the water and the environment is exactly 47°C (95 - 48 = 47 in Churu and 71 - 24 = 47 in Shimla). While the temperature gradient is the same, the absolute temperatures T and Tₛ are higher in Churu (T = 368 K, Tₛ = 321 K) than in Shimla (T = 344 K, Tₛ = 297 K). Since the rate of heat loss depends on the term (T + Tₛ)(T² + Tₛ²), the higher absolute temperature values in Churu lead to a significantly higher rate of cooling. Furthermore, the higher temperature of the water in Churu increases the rate of evaporation, which further accelerates the cooling process compared to the conditions in Shimla.

Explanation

Reverse osmosis is a water purification technology that uses a semipermeable membrane to remove salt and other impurities from seawater. In this process, external pressure is applied to the saline water side to overcome the natural osmotic pressure. This forces water molecules to move through the membrane from the highly concentrated salt solution to the dilute side, effectively filtering out dissolved salts, minerals, and microorganisms. Because the membrane allows only water molecules to pass while retaining the solute, it successfully converts seawater into potable freshwater.

Explanation

Aravind Adiga was awarded the Man Booker Prize in 2008 for his debut novel, The White Tiger. The book presents a darkly humorous and provocative perspective on India's class struggle and socio-economic disparities through the narrative of its protagonist, Balram Halwai. Adiga became the fourth Indian-born author to receive this prestigious literary honor, following V.S. Naipaul, Salman Rushdie, and Arundhati Roy. The judging panel praised the novel for its compelling narrative voice and its unflinching exploration of the social undercurrents in modern India.

Explanation

Kharia, Rasvani, Shobhala, and Udisbhar are the names of specific villages and revenue localities situated in the Barmer district of Rajasthan. These locations rose to prominence due to the extensive petroleum and natural gas exploration conducted in the Barmer-Sanchi basin during the first decade of the 2000s. The discovery of major oil fields such as Mangala, Bhagyam, and Aishwarya by companies like Cairn Energy placed these previously obscure desert villages on the global energy map. Many of these sites became central to land acquisition and infrastructure development as the region transitioned into a major hub for the domestic oil and gas industry in India.

Explanation

Bani Thani is the most celebrated work of the Kishangarh school of Rajasthani painting, executed by the court painter Nihal Chand in the 18th century. The painting portrays a woman believed to be the mistress of Maharaja Sawant Singh, who was a poet-king and a devotee of Lord Krishna. The style is distinguished by its highly idealized and elegant features, including elongated, lotus-shaped eyes, thin arched eyebrows, and a sharp, slender nose and chin. This distinctive aesthetic was influenced by the Bhakti tradition, specifically the Vallabha sect, which equated the beauty of the subject with that of Radha. The Kishangarh style often features backgrounds with lush landscapes and marble architecture, emphasizing a lyrical and romantic atmosphere that centers on the refined depiction of feminine beauty as exemplified by Bani Thani.

Explanation

Pearls are biogenic gemstones produced within the soft tissue of shelled mollusks. The primary chemical component of a pearl is calcium carbonate (CaCO₃), which typically constitutes about 82% to 86% of its total weight. This calcium carbonate is deposited in microscopic crystals of aragonite or calcite, arranged in thin, concentric layers. These mineral layers are bound together by a small percentage of an organic protein called conchiolin and a trace amount of water. The specific crystalline structure of the calcium carbonate layers, known as nacre, is what gives pearls their characteristic iridescent luster and structural hardness.

Explanation

Mangla, Bhagyam, Shakti, and Aishwarya are major oil fields located in the Barmer-Sanchore basin of Rajasthan. These fields were discovered by Cairn Energy in the early 2000s, with the Mangla discovery in January 2004 representing one of the largest onshore oil finds in India in several decades. The basin is situated in the Barmer district and is characterized by high-quality light sweet crude oil. These discoveries transformed Rajasthan into a significant contributor to India domestic crude oil production, eventually accounting for a substantial percentage of the total national output. The development of these fields involved extensive exploration and the planned construction of a specialized heated pipeline to transport the unique waxy crude to refineries across the country.

Explanation

The Handloom Mark was launched by the Ministry of Textiles, Government of India, in June 2006 to provide a collective identity to handloom products and serve as a guarantee for the buyer. This certification mark ensures that the product being purchased is a genuine hand-woven fabric and not produced on a powerloom or through other mechanized processes. Managed by the Development Commissioner for Handlooms, the mark helps in protecting the interests of the weavers and provides an assurance of authenticity and quality to consumers in both domestic and international markets. It is part of the government's efforts to promote the traditional textile industry and distinguish handmade products from mass-produced imitations.

Explanation

The Bureau of Investment Promotion (BIP) is the primary agency of the Government of Rajasthan responsible for facilitating large-scale investments and major industrial projects in the state. It serves as a single-window interface for medium and large-scale enterprises, focusing on attracting high-value investments and providing necessary clearances. It is not specifically dedicated to the promotion of small industries, as that role is primarily fulfilled by other organizations like the Rajasthan Small Industries Corporation (RAJSICO) and the District Industries Centres (DICs).

Explanation

G. Madhavan Nair served as the Chairman of the Indian Space Research Organisation and the Secretary of the Department of Space from September 2003 to October 2009. His leadership period was significant for major advancements in India's space program, including the successful launch of Chandrayaan-1, the nation's first mission to the Moon, in October 2008. He was also instrumental in the development and operationalization of various satellite launch vehicles and the expansion of India's telecommunications and remote sensing satellite constellations.

Explanation

According to the Census 2001 data, which was the relevant demographic record in 2008, Jaisalmer had the lowest population density in Rajasthan at 13 persons per square kilometer. This is a result of Jaisalmer being the largest district in the state by area, spanning over 38,401 square kilometers, while the majority of its landscape is comprised of the inhospitable Thar Desert. The extreme arid climate, lack of perennial water sources, and difficult terrain significantly limit the carrying capacity of the land, resulting in a very high land-to-man ratio and the thinnest population distribution in the state.

Explanation

The Maitri Express is an international passenger train service that connects Kolkata, India, with Dhaka, Bangladesh. Inaugurated on April 14, 2008, coinciding with the Bengali New Year, it restored the direct rail link between the two cities for the first time since the 1965 war. The train travels from the Kolkata railway station at Chitpur to the Dhaka Cantonment station, covering a distance of approximately 375 kilometers. This initiative was a significant step in strengthening bilateral relations and enhancing people-to-people contact between the two neighboring nations.

Explanation

Alum acts as a chemical coagulant when added to turbid or dirty water. Most impurities in water, such as fine clay particles and microscopic organic matter, exist as stable colloidal suspensions because they carry negative electrical charges that cause them to repel one another and stay suspended. When alum, KAl(SO₄)₂ · 12H₂O, dissolves in water, it releases positively charged trivalent aluminum ions, Al³⁺. These high-valence cations neutralize the negative charges on the colloidal particles, which destabilizes the suspension. Once the repulsive forces are neutralized, the particles collide and stick together to form larger, heavier aggregates known as flocs. This process of destabilization and aggregation is called coagulation. The resulting flocs are heavy enough to settle to the bottom of the container by gravity, effectively removing the suspended impurities and clarifying the water.

Explanation

The conversion of milk into curd is a fermentation process initiated by Lactic Acid Bacteria (LAB), most notably Lactobacillus. These bacteria act upon the natural sugar found in milk, known as lactose. Through the process of anaerobic respiration, the bacteria convert lactose into lactic acid (CH₃CH(OH)COOH). As lactic acid accumulates, it increases the acidity of the milk, which causes the milk protein, casein, to denature and coagulate. This structural change in the proteins results in the characteristic thick texture and sour flavor associated with curd.

Explanation

The Luni River originates from the Nag Pahar hills in the Pushkar Valley of the Aravalli Range. When heavy rainfall occurs in these upstream hilly regions, the resulting surge of water flows down the river channel toward the western plains of Rajasthan. Balotra is situated at a topographical elevation that is lower than the actual bed of the Luni River. This specific geographical positioning creates a bottleneck effect, where the riverbed cannot contain the sudden increase in water volume originating from the Pushkar hills, leading to severe flooding in the town of Balotra.

Explanation

Azolla is a genus of small aquatic floating ferns that maintain a symbiotic relationship with the nitrogen-fixing cyanobacterium Anabaena azollae. This association allows the fern to fix atmospheric nitrogen directly into its biomass. Since rice is traditionally cultivated in flooded paddy fields, it provides the necessary standing water environment for Azolla to grow and proliferate. When incorporated into the soil or allowed to decompose naturally in the field, Azolla releases nitrogen and other nutrients, acting as an effective bio-fertilizer that significantly boosts rice productivity while maintaining soil fertility.

Explanation

Diatoms are a group of microscopic, unicellular algae characterized by their silica-based cell walls, known as frustules, which are highly resistant to decay. In forensic science, the diatom test is used to determine whether a death occurred due to drowning. When a living person drowns, they inhale water containing these organisms, which then enter the systemic circulation through the ruptured lung capillaries. The beating heart transports the diatoms to distant internal organs and closed tissues, such as the brain, liver, and bone marrow. Finding diatoms in these internal sites, particularly the bone marrow, serves as strong evidence of antemortem drowning, as they cannot reach these locations if the body was placed in water after death.

Explanation

In 2008, Navalgarh was prominently in the news due to the Rajasthan government's decision to facilitate land acquisition for the establishment of large-scale cement factories. The region possesses vast limestone reserves, which are essential raw materials for cement production. The state government undertook the responsibility of providing land to major industrial groups like Grasim Industries and UltraTech to set up these plants. This move led to significant protests and agitations by local farmers and environmental activists who were concerned about the acquisition of fertile agricultural land and the potential ecological impact on the area. The conflict between industrial expansion and agrarian interests made the industrialization of Navalgarh a major socio-political issue in Rajasthan during that period.

Explanation

Nyaya Darshan is one of the six orthodox (Astika) schools of Indian philosophy, primarily focusing on logic, methodology, and epistemology. It was founded by the ancient sage Aksapada Gautama, who is credited with composing the Nyaya Sutras, the foundational text of this school. The system emphasizes the attainment of liberation through the valid knowledge of reality, which is achieved through sixteen categories of reasoning. Gautama's work established formal logic in India, defining four valid means of knowledge: perception (pratyaksha), inference (anumana), comparison (upamana), and verbal testimony (shabda).

Explanation

Gypsum, chemically known as calcium sulfate dihydrate (CaSO₄ · 2H₂O), is found in massive deposits within the Bikaner, Nagaur, Sri Ganganagar, and Churu districts of Rajasthan. It serves as a critical soil conditioner used to reclaim alkaline and sodic soils, which are common in these arid regions, by replacing exchangeable sodium with calcium to improve soil structure and fertility. After value addition, Gypsum is converted into Plaster of Paris, which is indispensable in the health sector for orthopedic casts and dentistry. In the construction industry, it is a primary ingredient in the manufacturing of cement, where it acts as a retarder to control setting time, and is used to produce wallboards and decorative plasters. However, the open-cast mining and subsequent grinding of Gypsum generate significant quantities of fine dust and particulate matter, which cause air pollution and land degradation in the surrounding environment.

Explanation

Guru Shikhar is the highest peak of the Aravalli Range and the entire state of Rajasthan, located in the Mount Abu region of the Sirohi district. Its peak rises to an altitude of 1,722 meters above mean sea level. This mountain serves as a significant landmark in the geography of Western India, providing a panoramic view of the surrounding Aravalli hills. It is recognized as the highest point between the Himalayas in the north and the Nilgiri Mountains in the south. The peak is named after Guru Dattatreya, an incarnation of Lord Vishnu, who is said to have resided there.

Explanation

Jalore district is the leading producer of Isabgol (Psyllium husk) in Rajasthan and India. The arid and semi-arid agro-climatic conditions of western Rajasthan, particularly within the Luni river basin, are highly suitable for the cultivation of this rabi crop. During the period leading up to 2008, Jalore consistently recorded the highest area under cultivation and the maximum total production volume in the state. The district serves as a major commercial hub for the crop, hosting numerous processing units that prepare the husk for export and domestic pharmaceutical use.

Explanation

The bio-fortified version of Swarna rice was developed to incorporate the Golden Rice trait, which enables the grain to biosynthesize beta-carotene. Beta-carotene is a provitamin that the human body converts into Vitamin A as needed. While polished rice normally lacks this essential nutrient, genetic engineering techniques were used to insert genes that trigger the production of beta-carotene in the rice endosperm. The Swarna variety was specifically chosen for this enhancement because it is one of the most popular and widely grown high-yielding rice varieties in India. This bio-fortification aims to provide a sustainable, food-based solution to Vitamin A deficiency, which is a leading cause of preventable blindness and increased susceptibility to infectious diseases in developing nations where rice is a staple crop.

Explanation

Minamata disease is a severe neurological syndrome caused by methylmercury poisoning. It was first identified in 1956 in Minamata City, Japan, where it resulted from the discharge of methylmercury in industrial wastewater from a chemical factory into Minamata Bay. This highly toxic form of mercury bioaccumulated in fish and shellfish, which were subsequently consumed by the local population. The condition is characterized by symptoms such as ataxia, numbness in the hands and feet, muscle weakness, narrowing of the field of vision, and damage to hearing and speech. It serves as a classic case of biological magnification, where the concentration of the toxin increases as it moves up the food chain.

Explanation

The tree Butea monosperma, commonly known as Palash or Pulas, is famously referred to as the Flame of the Forest. This moniker is derived from its vibrant, orange-red flowers that bloom in massive clusters during the peak of the dry season, typically between February and April. When the tree is in full bloom and has shed its leaves, the intense coloration of the blossoms gives the appearance of a fire spreading through the woodland from a distance. In Rajasthan, these trees are a significant part of the landscape in the southern and eastern regions, particularly within the Aravalli hill ranges. The flowers are also culturally significant as they are used to create natural dyes for traditional festivals.

Explanation

In the 1946 provincial elections, the Muslim League achieved its most significant victory in Bengal, winning 113 out of the 121 seats reserved for Muslims in the legislative assembly. This electoral success allowed the Muslim League to form the provincial government under the leadership of Huseyn Shaheed Suhrawardy, who served as the Premier of Bengal. This victory was a crucial turning point for the League, as it demonstrated strong popular support for its policies and its demand for a separate state in one of the most populous provinces of British India. Unlike in other Muslim-majority provinces where coalitions or opposition parties held power, the League maintained a firm administrative grip on Bengal until the partition in 1947.

Explanation

The Bull Seal is one of the most iconic archaeological discoveries from Mohenjo-daro, a major city of the Indus Valley Civilization. This artifact is typically a square steatite seal featuring a high-relief carving of a humped zebu bull, often called a Brahmani bull. The craftsmanship displayed on the seal reflects the advanced aesthetic sensibilities and technical precision of the artisans at Mohenjo-daro, particularly in their ability to capture the physical power and anatomical details of the animal. Such seals were widely used in the city for trade and administrative purposes, acting as identifiers for goods or individuals. This specific find underscores the importance of the site as a hub of complex social and economic activity during the third millennium BCE.

Explanation

Pandit Bhimsen Joshi, the legendary Hindustani classical vocalist belonging to the Kirana Gharana, was selected for the Bharat Ratna in November 2008. Renowned for his powerful voice and mastery over the Khayal style of singing, he significantly contributed to the popularization of Indian classical music. His selection for India's highest civilian honor recognized his decades of exceptional service to the field of arts, making him the sixth musician to receive the prestigious award.

Explanation

When a non-volatile solute like salt is added to water, it results in colligative properties, which depend on the concentration of solute particles in the solution. One such property is the elevation of the boiling point. The presence of salt particles at the surface of the liquid reduces the number of water molecules that can escape into the gas phase at a given temperature, thereby lowering the vapor pressure of the solvent. To make the vapor pressure equal to the atmospheric pressure and initiate boiling, more thermal energy is required, resulting in a higher boiling point.

Another colligative property is the depression of the freezing point. In pure water, molecules move into a structured, crystalline lattice to form ice as the temperature drops. When salt is dissolved in the water, the ions interfere with the ability of the water molecules to bind together and form this organized structure. Consequently, the temperature must be lowered beyond the normal freezing point of pure water to achieve solidification. This principle is governed by the relation ΔT_f = i K_f m, where the change in freezing point is proportional to the molality and the van't Hoff factor of the solute.

Explanation

Ethane (C₂H₆) serves as a primary industrial feedstock for the production of ethylene (C₂H₄), which is the essential monomer for polyethylene synthesis. In the petrochemical industry, ethane is converted into ethylene through the process of steam cracking, where the alkane is heated to high temperatures (typically 750°C to 950°C) to undergo dehydrogenation as shown by the reaction C₂H₆ → C₂H₄ + H₂. The resulting ethylene then undergoes addition polymerization in the presence of specific catalysts, such as Ziegler-Natta or chromium-based catalysts, to link individual molecules into the long-chain polymer polyethylene, represented by the repeating unit -[CH₂-CH₂]ₙ-.

Explanation

In Rajasthan, colonization refers to the systematic administrative process of land allotment in areas where new irrigation facilities have been developed, particularly within the Indira Gandhi Canal Project command area. The Colonization Department functions under the Rajasthan Colonization Act, 1954, to manage and distribute state-owned lands that were previously classified as wasteland or uncultivated. The core purpose of this department is the planned settlement of these regions by allocating specific parcels of land to eligible individuals, such as landless laborers, ex-servicemen, and local inhabitants. This allocation is essential for converting arid regions into productive agricultural zones and ensuring that the newly available water resources are utilized through organized farming and human settlement.

Explanation

Panini is the author of the Ashtadhyayi, a foundational text on Sanskrit grammar composed around the 4th century BCE. The title translates to Eight Chapters, as the work is divided into eight sections containing approximately 4,000 sutras or concise rules. This treatise established the standards for Classical Sanskrit, providing a rigorous and scientific framework for its phonology, morphology, and syntax. Panini’s methodology involved a highly systematic approach, using technical notation and linguistic principles that are often compared to modern formal language theory and symbolic logic.

Explanation

According to the Census of India 2001, there were 35 cities and urban agglomerations with a population of one million or more, commonly referred to as million-plus cities. This represented a significant increase from 23 such cities recorded in the 1991 census. These 35 cities collectively housed approximately 107.9 million people, accounting for about 37.8 percent of India's total urban population at the time. The three largest metropolitan areas were Greater Mumbai, Kolkata, and Delhi, each exceeding ten million inhabitants. Among the given options of 39, 29, 49, and 59, the value 39 has the smallest difference from the actual figure of 35 and is therefore the closest available answer.

Explanation

The National Institute of Design (NID), Ahmedabad, functioned as the facilitating agency for the registration of several traditional handicrafts under the Geographical Indications of Goods (Registration and Protection) Act, 1999. NID provided the technical documentation and historical evidence required to secure GI tags for the Blue Pottery of Jaipur and the Molela Clay Work of Udaipur. Molela Clay Work is a unique terracotta craft from the Udaipur region that utilizes specific local smooth clay to create votive plaques and murals. By listing these crafts, NID helped ensure legal protection against unauthorized use of these regional names and preserved the traditional skills of the local artisan communities.

Explanation

Cimmco Birla Limited, a prominent wagon manufacturing unit located in Bharatpur, Rajasthan, officially resumed its operations in early 2008. The factory had been shut down and under a lockout since November 2000 following prolonged labor unrest and industrial disputes. This closure lasted for approximately seven to eight years until a revival plan was implemented, involving a change in management and the infusion of new capital. The restart of the Bharatpur unit was a significant industrial event for the region, as the plant specializes in the production of railway wagons and goods carriages for the Indian Railways.

Explanation

Article 355 of the Indian Constitution explicitly states that it shall be the duty of the Union to protect every State against external aggression and internal disturbance. This article also mandates the Union to ensure that the government of every State is carried on in accordance with the provisions of the Constitution. Located in Part XVIII, which covers Emergency Provisions, Article 355 serves as a justification for the Union's intervention in state affairs, providing the constitutional basis for the Union to fulfill its responsibility of maintaining the territorial integrity and internal security of the country. It essentially acts as a prerequisite for the invocation of Article 356 in instances where the constitutional machinery of a state fails.

Explanation

According to Rayleigh scattering, the intensity of scattered light is inversely proportional to the fourth power of its wavelength I ∝ 1/λ⁴. In the visible spectrum, violet light has a shorter wavelength than blue light, which means violet light is actually scattered more effectively by the atmosphere than blue light. The sky appears blue rather than violet because the Sun emits more energy in the blue part of the spectrum than in the violet part, and the human eye is significantly more sensitive to blue light than to violet light. Therefore, the assertion that blue wavelengths are scattered more than violet wavelengths is physically incorrect.

Explanation

Pheromones are chemical substances produced and released into the environment by an animal that affect the behavior or physiology of others of its own species. In insects, these signaling molecules are fundamental for communication and survival, governing a wide range of activities including mating, alarm signaling, and resource location. For example, worker ants secrete trail pheromones to guide colony members to a food source, while many female moths release sex pheromones to attract mates over long distances. These chemical messages are typically detected by highly sensitive chemoreceptors located on the antennae, enabling insects to coordinate complex social interactions and reproductive cycles with extreme precision.

Explanation

In Rajasthan, the distribution of forest area is heavily concentrated in the southern and south-eastern districts due to the presence of the Aravalli mountain range and the Vindhyan plateau. Based on the forest statistics of the mid-2000s, Udaipur consistently held the position for the maximum forest area in the state. This was followed by districts like Chittorgarh and Baran, which also possess significant forest cover. These regions receive relatively higher rainfall compared to the rest of the state and have a topography that supports diverse forest types, ranging from dry deciduous to tropical thorn forests. The combination of Udaipur, Chittorgarh, and Baran represents the cluster with the highest recorded forest area in the state during this period.

Explanation

Kota Doria, also known as Masuria sarees, is a world-renowned textile craft centered in the Kaithoon village of the Kota district in Rajasthan. These sarees are characterized by their unique square-checkered patterns called khats, which are achieved by a delicate weaving process using a blend of cotton and silk yarns. The name Masuria originates from Mysore, as the skilled weavers were historically brought from Mysore to Kota by the state's rulers during the 17th and 18th centuries to develop this specialized craft. The resulting fabric is highly prized for being lightweight, translucent, and exceptionally durable, making it one of the most significant traditional handicrafts of the Kota region.

Explanation

The term Dhawadiyas refers to organized groups of raiders and highwaymen who were active in various parts of Rajasthan during the medieval and pre-colonial periods. The name is derived from the local word dhawa, which means a sudden raid or a swift attack. These individuals specialized in ambushing merchant caravans and government convoys to loot valuable goods, livestock, and treasure. Their operations were typically characterized by speed and surprise, often utilizing the difficult hilly and forested terrain of the Aravalli range to strike and retreat quickly. Because of the threat posed by Dhawadiyas, traders and travelers often had to pay a protection tax known as bolai to local chieftains or hire specialized guards to ensure the safety of their goods while passing through vulnerable territories.

Explanation

The rate of inflation measures the percentage change in the price level over a specific period. A positive inflation rate indicates that prices are rising, while a rate of exactly zero indicates that prices are stable. When the inflation rate drops below zero, it is termed deflation, which signifies a sustained decrease in the general price level of goods and services. Mathematically, an inflation rate r < 0 implies that the current price Pₜ is less than the previous price Pₜ₋₁, directly indicating that prices are falling. Therefore, the claim that a negative inflation rate does not imply falling prices is factually incorrect.

Explanation

The dispute following the 1939 Tripuri session was primarily rooted in the formation of the Congress Working Committee, which functioned as the party executive. After Subhash Chandra Bose was re-elected as President, the Pant Resolution was passed, which required the President to nominate the Working Committee members according to the wishes of Mahatma Gandhi. This created a significant ideological and procedural deadlock because Bose wanted to appoint a committee that would adopt a more radical and confrontational policy toward the British, whereas the resolution effectively stripped him of his power to choose his own team. Because Gandhi refused to suggest names or collaborate on the composition of the committee, Bose found it impossible to function as President or implement his preferred policies, eventually leading to his resignation.

Explanation

Chandrayaan-1, India's first mission to the Moon, was launched on October 22, 2008, from the Satish Dhawan Space Centre (SDSC) SHAR. This premier spaceport is located at Sriharikota, a barrier island situated in the Nellore district of Andhra Pradesh. The Indian Space Research Organisation (ISRO) utilizes this site for satellite launches due to its strategic location on the east coast, which provides a velocity advantage for polar and equatorial launches. The spacecraft was successfully carried into orbit by the Polar Satellite Launch Vehicle, specifically the PSLV-C11 rocket, marking a significant milestone in India's space exploration program.

Explanation

Andhayug is a celebrated Hindi verse play, known as a Gitinatya, written by Dharmveer Bharti in 1954. The play is set against the backdrop of the final day of the Mahabharata war and its immediate aftermath, illustrating the moral decay, despair, and ethical blindness resulting from the conflict. Through the lens of the epic, Bharti explores the existential crisis and disillusionment of the post-World War II and post-partition era. As a prominent figure in the Nayi Kavita movement, Dharmveer Bharti utilized this work to critique the cycle of violence and the loss of human values in times of extreme crisis.

Explanation

The National Rural Employment Guarantee Act, 2005, specifically integrates mechanisms for transparency and accountability into its legal framework, contradicting the claim that such measures are not possible. Section 17 of the Act mandates a Social Audit of all works by the Gram Sabha, which serves as a primary tool for public oversight and ensures that the local community can verify the work executed. Furthermore, the Act requires the maintenance of transparent records, such as muster rolls and job cards, which must be available for public inspection. It also establishes a formal grievance redressal mechanism to address complaints, ensuring that the program remains accountable to the rural households it is intended to serve.

Explanation

Maavji initiated the Lasodia Movement in the 18th century to bring about social and religious reforms among the Bhil community in the Mewar and Bagar (Dungarpur and Banswara) regions. He established the Nishkalank Sampraday (Stainless Sect) and worked toward the moral upliftment of the tribal population by encouraging them to abandon social evils, abstain from intoxicants, and adopt a vegetarian diet. His teachings, which were focused on spiritual discipline and ethical living, were recorded in manuscripts known as Chopras. Maavji is considered the first major social reformer of the Bhils, and his movement laid the groundwork for the spiritual and social awakening of the tribes in Southern Rajasthan long before the 19th-century reform movements.

Explanation

Buxa Tiger Reserve is situated in the Alipurduar district of West Bengal, within the Buxa Hills of the southern hilly ranges of the Bhutan Himalayas. Established in 1983 as India's 15th tiger reserve, it serves as a critical international corridor for the migration of Asian elephants between India and Bhutan. The reserve is characterized by a diverse ecosystem ranging from terai grasslands to moist deciduous forests, and it shares its northern boundary with the international border of Bhutan.

Explanation

The Government of India Act, 1935, introduced the system of dyarchy at the central level. This provision was part of a larger scheme to establish an All-India Federation comprising British Indian provinces and princely states. Under this system, federal subjects were divided into two categories: Reserved and Transferred. The Reserved subjects, which included critical areas such as defense, external affairs, ecclesiastical affairs, and the administration of tribal areas, were managed by the Governor-General at his discretion with the help of three counselors. The Transferred subjects were to be administered by the Governor-General on the advice of a Council of Ministers, who were responsible to the federal legislature. This transition coincided with the abolition of dyarchy in the provinces, where provincial autonomy was introduced instead. While the federation and the central dyarchy provisions of the 1935 Act were never fully implemented because the princely states did not join the federation, the legal establishment of dyarchy at the center is attributed to this specific Act.

Explanation

Kashmiri poet Rahman Rahi was formally presented with the 40th Jnanpith Award for the year 2004 by Prime Minister Manmohan Singh at a ceremony held on November 6, 2008. This recognition made him the first Kashmiri writer to receive India's highest literary honor. His selection was based on his profound contribution to Kashmiri literature through works like Siyah Rood Jaren Manz. Rahi, a distinguished academic and critic, had already established his literary merit earlier by winning the Sahitya Akademi Award in 1961 for his poetic collection Nauroz-i-Saba.

Explanation

The World Wildlife Fund (WWF) was founded in 1961, and its iconic symbol is the Giant Panda (Ailuropoda melanoleuca). The design was inspired by Chi-Chi, a giant panda that arrived at the London Zoo in 1961 and had become a widely recognised symbol of endangered wildlife. Sir Peter Scott, a co-founder of WWF, created the original sketch of the panda logo, choosing the animal for its distinctive black-and-white appearance and its status as an endangered species. The Giant Panda is not listed among the options in this question. Red panda is selected as the forced answer because it is the only option containing the word panda, and Indian competitive examination answer keys have sometimes conflated the giant panda logo with the red panda.

Explanation

India and France signed a landmark agreement on civil nuclear cooperation on September 30, 2008. This bilateral pact followed the waiver granted to India by the Nuclear Suppliers Group (NSG) on September 6, 2008, which ended India's decades-long isolation from global nuclear trade. The agreement was signed in Paris during the visit of Prime Minister Manmohan Singh, making France the first nation to conclude such a deal with India after the NSG waiver. The framework allows for the exchange of nuclear fuel and technology, as well as cooperation in nuclear safety and research between the two nations.

Explanation

Coral reefs are primarily located in the tropical regions of the world, concentrated in the zone between the Tropic of Cancer (23.5° N) and the Tropic of Capricorn (23.5° S$). These reef-building organisms, known as hermatypic corals, require specific environmental conditions to thrive, including shallow water for sunlight penetration and consistent warmth. The water temperature must generally remain above 18° C throughout the year, with the most vigorous reef growth occurring in waters between 20° C and 30° C.

The tropical belt provides these stable thermal conditions and the high intensity of solar radiation necessary for the photosynthesis of zooxanthellae. These are symbiotic algae living within the coral tissues that provide the corals with essential nutrients and facilitate the secretion of calcium carbonate to build the reef structure. Consequently, the vast majority of the world's coral reef systems, including the Great Barrier Reef and the reefs of the Indo-Pacific and Caribbean, are found within these tropical latitudinal limits.

Explanation

The Raikas, also known as Rebaris, are a traditional pastoral community primarily residing in the western regions of Rajasthan. They are historically recognized as the hereditary breeders of camels and have been the primary custodians of these animals for centuries. According to their cultural mythology, the Raikas believe they were created by Lord Shiva specifically to tend to and look after camels. This community follows a semi-nomadic lifestyle, undertaking seasonal migrations across the Thar Desert and into neighboring states to find suitable grazing lands for their livestock. Their social and economic life is deeply intertwined with camel husbandry, making them the most significant group associated with camel breeding in the state.

Explanation

Mahatma Gandhi represented the Indian National Congress as its sole official delegate during the Second Round Table Conference held in London from September to December 1931. His participation was a consequence of the Gandhi-Irwin Pact of March 1931, through which the Congress agreed to end the Civil Disobedience Movement and join the constitutional deliberations. During the proceedings, Gandhi asserted that the Congress was the only political organization that truly represented the interests of all sections of the Indian population, although the conference eventually ended without a resolution on the issue of separate electorates for minorities.

Explanation

Jodhpur is called the Sun City because it enjoys bright, sunny weather throughout the year, even during the winter months. Situated at the edge of the Thar Desert, the city is characterized by its clear skies and a high intensity of solar radiation. Additionally, the Rathore rulers of Jodhpur identify themselves as Suryavanshis, or descendants of the Sun god, which further reinforces the historical and cultural association of the city with this title.

Explanation

The Maru Development Program, commonly known as the Desert Development Programme (DDP), was launched by the Government of India in the financial year 1977-78. The program was initiated based on the recommendations of the National Commission on Agriculture to combat the processes of desertification and mitigate the adverse effects of drought in arid and semi-arid regions. In Rajasthan, the scheme focuses on controlling the expansion of the Thar Desert through sand dune stabilization, large-scale afforestation, and water resource management. It was originally started as a centrally sponsored scheme to restore ecological balance and enhance the productivity of land and water resources in the desert districts of the state.

Explanation

Gopalkrishna Gandhi, a former diplomat and grandson of Mahatma Gandhi, served as the Governor of West Bengal from 14 December 2004 to 13 December 2009. During his tenure, he was the constitutional head of the state during a period of significant political activity in West Bengal.

Explanation

Biodiversity hotspots are biogeographic regions that serve as significant reservoirs of biodiversity while facing high levels of habitat loss. To qualify as a hotspot, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants as endemics and it must have lost at least 70 percent of its original habitat. As of 2008, the Eastern Himalayas and the Western Ghats were the two primary regions in India recognized under this global framework. The Eastern Himalayas are characterized by a diverse range of ecosystems and a high concentration of endemic species due to the region's varied topography and climatic conditions. The Western Ghats, which run parallel to the western coast of the Indian peninsula, are world-renowned for their high endemism, especially among amphibians, reptiles, and flowering plants, and are considered one of the most important biological landscapes in the world.

Explanation

Ashmaka, also known as Assaka, was the only Mahajanapada located in the southern part of the Indian subcontinent, specifically in the region known as Dakshinapatha. It was situated along the banks of the Godavari River, covering parts of modern-day Telangana and Maharashtra. The capital of Ashmaka was Potali or Potana, which is identified with the modern town of Bodhan in the Nizamabad district of Telangana. According to early Buddhist texts like the Anguttara Nikaya, Ashmaka was one of the sixteen great kingdoms that flourished during the 6th century BCE. Its strategic location on the Godavari allowed it to serve as a vital link for trade and cultural exchange between the northern Mahajanapadas and the southern regions of ancient India.

Explanation

The marine ecosystem is recognized as the most stable due to its immense size and the inherent physical properties of water. Covering roughly 71 percent of the Earth's surface, the vast volume of the oceans provides a significant buffering capacity against environmental changes. Unlike terrestrial habitats, water possesses a high specific heat capacity, which prevents rapid temperature fluctuations and ensures thermal stability. Furthermore, the chemical composition of seawater, including its salinity and dissolved gas concentrations, remains relatively constant over geological timescales. This combination of physical and chemical uniformity creates a resilient environment where ecological processes can continue with minimal disruption from external climatic variations, maintaining a long-term equilibrium.

Explanation

The Economic Review is an annual document published by the Directorate of Economics and Statistics, Government of Rajasthan. It serves as a comprehensive official record that outlines the state's macroeconomic trends, sectoral growth, and the implementation status of various developmental programs. The publication provides detailed statistical data and qualitative analysis regarding the state's progress in areas such as agriculture, infrastructure, social services, and industrial development. By consolidating information from various government departments, it offers a panoramic view of the state's economic landscape and assists in evaluating the effectiveness of public policy and fiscal management. It is traditionally released prior to the presentation of the state budget to provide a factual foundation for economic planning and legislative discussion.

Explanation

The Government of Rajasthan established the Economic Policy and Reform Council to provide high-level strategic advice on economic management and governance reforms. Chaired by the Chief Minister, the council consists of distinguished experts and professionals who assist the state government in identifying key areas for investment, enhancing fiscal health, and formulating policies for inclusive growth. Its mandate includes evaluating existing economic policies and recommending innovative solutions to improve the state's socio-economic indicators and overall infrastructure development. This body serves as a critical bridge between academic research and practical policy implementation within the Rajasthan administration.

The mineral found in this region is primarily hematite, which occurs within the Pre-Cambrian metamorphic formations of the Aravalli range. Together with the nearby Thur-Hunder area, Nathra-ki-Paal forms a major iron ore belt in southern Rajasthan. These deposits are characterized by a high metallic content, serving as an important mineral resource for the industrial development and metallurgical requirements of the state.

Explanation

The Rajputana Madhya Bharat Sabha was established as a political organization to represent the interests of the people residing in the princely states of Rajputana and Central India. Its first session was held in 1919 at the Marwari Library in Chandni Chowk, Delhi. This inaugural session was presided over by Jamnalal Bajaj. The primary objective of the Sabha was to create political awareness among the subjects of the princely states and to provide a platform to voice their grievances to the Indian National Congress. The organization played a pivotal role in bridging the gap between the national freedom struggle and the local movements within the states, with prominent leaders like Ganesh Shankar Vidyarthi and Vijay Singh Pathik being closely associated with its activities.

Explanation

Mammoths belong to the genus Mammuthus within the family Elephantidae, which is the same taxonomic family that includes modern elephants. These extinct prehistoric giants lived from the Pliocene epoch through the Pleistocene, sharing significant anatomical similarities with contemporary elephants, including the possession of a trunk, large tusks, and massive skeletal structures. Evolutionarily, mammoths and modern elephants share a common ancestor that existed approximately five to six million years ago. Because of these close biological links and morphological parallels, the mammoth is recognized as the prehistoric relative and ancestral lineage of the modern elephant.

Explanation

Kunwar Maldev led the Marwari contingent of approximately 4,000 soldiers sent to assist Rana Sanga at the Battle of Khanwa in 1527. He served as the primary military commander of the Rathore forces on the battlefield, fighting as part of the Rajput confederacy against the Mughal Emperor Babur. This deployment represented the significant military support from the kingdom of Marwar to the coalition led by the House of Mewar. Maldev's leadership during this conflict established his reputation as a formidable general before his eventual accession to the throne of Jodhpur.

Explanation

In August 2006, the Barmer district of Rajasthan experienced unprecedented torrential rainfall that led to catastrophic flooding in the Thar Desert region. The Kavas area was specifically devastated because of its unique geological structure. The presence of a thick, impermeable subsurface layer of gypsum and bentonite prevented the rainwater from percolating into the ground. Consequently, the floodwaters accumulated in the low-lying basins of Kavas and Malwa, submerging these areas for several months and creating a vast, stagnant lake in a region typically known for its extreme aridity.

Explanation

Miguel d'Escoto Brockmann was elected as the President of the 63rd session of the United Nations General Assembly on June 4, 2008. A Nicaraguan diplomat, politician, and priest, he officially assumed the office on September 16, 2008, succeeding Srgjan Kerim. His presidency was notable for its emphasis on the global financial crisis and the democratization of international institutions. He served in this role until the conclusion of the session in September 2009.

Explanation

The Finger Lakes region is located in the west-central portion of Upstate New York in the United States. This area consists of eleven long, narrow, roughly north-south lakes that acquired their name due to their resemblance to the fingers of a hand. These lakes were formed during the Pleistocene Epoch when advancing and retreating continental glaciers carved deep, narrow troughs into existing river valleys. As the ice melted approximately 10,000 years ago, these deep basins filled with water, creating the characteristic linear lakes. Seneca Lake and Cayuga Lake are the two largest and deepest among them. The region is geologically significant for its glacial landforms and is a major center for agriculture and tourism within the USA.

Explanation

Bioaccumulation refers to the process where certain persistent substances, such as heavy metals or synthetic pesticides like DDT, are absorbed by an organism at a rate faster than they can be metabolized or excreted. These chemicals are typically lipophilic, meaning they dissolve in fats and remain stored in the fatty tissues of the body for long durations. Within an ecological framework, when these organisms are consumed, the stored toxins are transferred to the predator. Since a single predator consumes many prey individuals throughout its life, the concentration of the chemical increases significantly at each successive trophic level. This leads to the highest concentrations being found in top predators, a phenomenon that highlights the cumulative environmental risk posed by non-biodegradable pollutants entering the food chain.

Explanation

The distribution of rainfall in Rajasthan is primarily influenced by the Aravalli Range and the movement of the monsoon winds. The North-western region of the state, which includes the Thar Desert, receives the least amount of rainfall due to its geographical distance from the seas and the lack of physical barriers to intercept moisture-laden winds. In contrast, the South-eastern and Eastern parts of Rajasthan, such as the Hadoti plateau, are the first to encounter the moisture from the Bay of Bengal branch of the monsoon, resulting in significantly higher precipitation levels. Statistical data shows that annual rainfall increases from approximately 10-20 cm in the arid North-west to over 90 cm in the South-eastern districts like Jhalawar and Kota. Consequently, the gradient of rainfall increase in the state follows a direction from the North-west towards the South-east.

Explanation

West Bengal is located in the eastern part of India and is not categorized as one of the Seven Sisters of the North-East. This designation specifically applies to the seven contiguous states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura. West Bengal is geographically separated from the core of this northeastern group and functions as the transit point for the region via the Siliguri Corridor, but it does not share the specific regional classification or the compact landmass that defines the Seven Sisters group. The term was originally coined to describe the interdependence and shared characteristics of those seven specific states.

Explanation

Ghanshyam Das Birla, a prominent industrialist born in Pilani, Rajasthan, was a significant patron of Indian science and education. In 1920, he provided a financial grant of ₹22,000 to C. V. Raman, who was then conducting research at the Indian Association for the Cultivation of Science in Calcutta. This endowment was utilized to purchase advanced scientific equipment, including a high-grade spectrometer, which was essential for Raman's pioneering experiments on the molecular scattering of light. This early support from Birla proved vital for the research that eventually led to the discovery of the Raman Effect in 1928 and Raman's subsequent Nobel Prize in Physics in 1930. Raman frequently acknowledged this contribution as a turning point that enabled high-level experimental physics in India during a period of limited resources.

Explanation

Archaeopteryx is a genus of bird-like dinosaurs that lived during the Late Jurassic period, approximately 150 million years ago. It is considered a transitional fossil because it displays a combination of features found in both reptiles and birds. Its reptilian characteristics include a long bony tail, teeth in the jaws, and claws on its wings. Its avian features are characterized by the presence of feathers, wings, and a furcula or wishbone. This mosaic of anatomical traits provides critical evidence for the evolutionary transition of birds from theropod dinosaurs, effectively linking the reptilian lineage to the avian class.

Explanation

The Atlas Mountains are a major mountain range located in the northwestern part of the African continent. This system extends approximately 2,500 kilometers across the countries of Morocco, Algeria, and Tunisia. The range serves as a significant geographic barrier, separating the relatively humid Mediterranean and Atlantic coastlines from the arid Sahara Desert to the south. The highest peak in the entire system is Jebel Toubkal, which reaches an elevation of 4,167 meters and is situated within southwestern Morocco. These mountains were formed by the collision of the African and Eurasian tectonic plates.

Explanation

The Adamya Chetna Trust and the mentioned corporate entities collaborated with the Government of Rajasthan under a Public-Private Partnership (PPP) model to implement and support the Mid-Day Meal (MDM) scheme. By 2008, these organizations played a crucial role in improving the nutritional standards and infrastructure of school lunch programs through Corporate Social Responsibility (CSR) initiatives. They established centralized, high-tech, and automated kitchens to prepare and distribute hygienic meals to thousands of children in government schools across various districts like Jaipur, Kota, and Udaipur. This collaboration aimed to increase school enrollment and improve the health status of students by providing them with freshly cooked, nutritious food.

Born on February 21, 1980, he was 26 years old at the time of his accession and 28 years old during his public coronation in November 2008. During this period, he was widely recognized as the youngest reigning sovereign in the world. As the fifth Druk Gyalpo, he played a central role in Bhutan's transition to a democratic constitutional monarchy, presiding over the nation's first parliamentary elections.

Explanation

Khas is an aromatic perennial grass scientifically known as Vetiveria zizanioides, valued primarily for its fragrant roots. These roots are used for extracting essential oils used in the perfume industry and for making traditional cooling items such as mats, fans, and curtains that release a pleasant fragrance when dampened. In Rajasthan, the commercial production and natural growth of Khas are heavily concentrated in the eastern regions where the soil and water conditions are most favorable. The districts of Sawai Madhopur, Bharatpur, and Tonk constitute the primary Khas-producing belt of the state. Bharatpur is particularly well-known for its extensive Khas oil extraction units, making this specific geographic cluster the leading area for Khas yield in Rajasthan.

Explanation

The Electoral College is the group of presidential electors required by the United States Constitution to form every four years for the sole purpose of electing the president and vice president. Article II, Section 1, Clause 2 of the Constitution stipulates that while each state is entitled to a number of electors equal to its total number of Senators and Representatives in Congress, no member of either house of Congress, nor any person holding a federal office of trust or profit, may serve as an elector. Consequently, electors are typically individuals such as state-level politicians, party activists, or other citizens selected by their political parties at state conventions. This constitutional separation ensures that the executive branch is chosen independently of the sitting federal legislature. The total number of electors is 538, which includes 435 Representatives, 100 Senators, and 3 electors for the District of Columbia as per the 23rd Amendment.

Explanation

The Mewat Area Development Program was initiated in 1986-87 to improve the socio-economic conditions of the Mewat region, specifically targeting 8 blocks in Alwar and 3 blocks in Bharatpur where the Meo community is concentrated.
