RPSC RAS Prelims 2007 Question Paper with Answers & Explanations

Explanation

Kubarpatti, also known as the Bankapatti or the fluoride belt, is a geographic region spanning the border areas of Nagaur and Ajmer districts in Rajasthan. The term literally translates to Hunchback Belt and refers to the high concentration of fluoride in the groundwater of this region. Prolonged consumption of this fluoride-rich water leads to a condition called skeletal fluorosis, which causes severe physical deformities, including the permanent bending of the vertebral column and stiffening of joints. This structural deformity gives affected individuals a hunched posture, from which the region derives its name. The high salinity and fluoride levels in the aquifer between Nagaur and Ajmer have made this area a significant zone for water-borne health issues in the state.

Explanation

The Battle of Dharmat was a significant conflict in the Mughal war of succession fought in April 1658. The village of Dharamt, also known as Dharmatpur, is situated on the banks of the river Gambhir, approximately 20 to 22 kilometers from the city of Ujjain. Historically, this site served as the location where the joint forces of Aurangzeb and his brother Murad Baksh encountered and defeated the imperial army led by Maharaja Jaswant Singh of Jodhpur, who was representing the interests of the crown prince Dara Shikoh. Because Ujjain is a major historical city and district center in the Malwa region of central India, the battlefield is located within the modern-day state of Madhya Pradesh. Following his victory, Aurangzeb renamed the site Fatehabad to commemorate the success.

Explanation

Kiran Desai was awarded the 2006 Man Booker Prize for her second novel, The Inheritance of Loss. At the time of her win, she became the youngest woman ever to receive this prestigious literary honor. The novel, set in the mid-1980s, tells the story of an embittered judge living in the Indian Himalayas, his granddaughter, and his cook, while simultaneously following the struggles of the cook's son as an illegal immigrant in New York. Her work was highly acclaimed for its intricate exploration of the effects of colonialism, identity, and the complexities of a globalized world.

Explanation

The earth's atmosphere is primarily composed of Nitrogen and Oxygen, which together account for about 99% of its total volume. Specifically, Nitrogen occupies approximately 78.08% and Oxygen about 20.95%. The remaining 1% consists of various trace gases. Among these, Argon is the most prevalent at approximately 0.934%. Carbon Dioxide (CO₂) is present in much smaller quantities, and around the year 2007, its concentration was approximately 0.038% by volume (equivalent to 380 parts per million). Since 0.038% is significantly lower than the percentages of Nitrogen, Oxygen, and Argon, Carbon Dioxide represents the smallest fraction by volume among the choices provided.

Explanation

During the Indian Rebellion of 1857, Captain Monk Mason served as the British Political Agent of Jodhpur. When the uprising spread to the Marwar region under the leadership of Thakur Kushal Singh of Auwa, Mason attempted to suppress the insurgent forces. In the conflict following the Battle of Chelawas, Captain Monk Mason was killed by the revolutionary forces. His head was subsequently severed and hung at the main gate of the Auwa Fort as a symbol of defiance against British authority. This event remains a significant episode in the history of the 1857 revolt within the princely states of Rajasthan.

Explanation

Bioremediation is an environmental biotechnology process that employs living organisms, typically microorganisms such as bacteria, yeast, or fungi, to break down or remove hazardous pollutants from soil, water, and other environments. These organisms utilize the contaminants as energy sources or nutrients, converting toxic chemicals into non-toxic substances like water, carbon dioxide, and other benign organic molecules through biochemical reactions. This method is widely applied in treating oil spills, industrial chemical leaks, and contaminated groundwater because it is often more cost-effective and less invasive than mechanical or chemical remediation methods. The process can be enhanced through biostimulation, where nutrients are added to the environment to encourage the growth of native microbes, or bioaugmentation, where specific pollutant-degrading microbes are added to the site.

Explanation

Aluminum is not a component of German Silver. German Silver is a ternary alloy typically consisting of 50 to 60 percent copper, 20 percent nickel, and 20 percent zinc. The alloy is named for its silvery-white luster, which is achieved through the inclusion of nickel, but it does not contain aluminum or elemental silver.

Explanation

Sriganganagar is recognized as the Anna Katora or the Grain Bowl of Rajasthan due to its exceptionally high agricultural productivity. The district benefits from an extensive irrigation network supplied by the Gang Canal and the Indira Gandhi Canal, which has transformed its arid landscape into the state's most fertile region. Because food energy or caloric value is a direct function of total food grain production, Sriganganagar leads the state in this metric. It consistently records the highest production of wheat and other cereal crops, which are the primary sources of dietary calories. The combination of high cropping intensity and superior yields per hectare ensures that this district provides the maximum food energy output in Rajasthan.

Explanation

The Algoja is a traditional woodwind instrument commonly used in the folk music of Rajasthan, Punjab, and Sindh. It consists of two joined beak flutes played simultaneously by a single performer. To produce sound, the musician blows air into the mouthpieces of both flutes at the same time, often using a circular breathing technique to maintain a continuous flow of music. One flute typically provides a constant drone while the other is used to play the melody. Within the classification of Indian musical instruments, the Algoja is categorized as a Sushira Vadya, which refers to instruments where sound is generated by the vibration of a column of air.

Explanation

Delhi is widely regarded as the melting pot of culture in India due to its long history as a seat of power for numerous dynasties, ranging from the Delhi Sultanate and the Mughals to the British Raj and the post-independence era. This historical evolution has facilitated a unique synthesis of varied cultural, linguistic, and religious influences over centuries. As the national capital, it serves as a cosmopolitan hub that attracts migrants from every corner of the country, resulting in a vibrant blend of traditions, festivals, and cuisines. The coexistence of ancient heritage sites alongside modern urban developments reflects a pluralistic identity that encapsulates the diversity of the entire nation within a single urban landscape.

Explanation

India accounts for approximately 4% of the world's renewable water resources. This figure is based on the country's total average annual flow in its river systems, which is estimated at 1,869 km³. This share is significant when compared to India's portion of the global land area, which is about 2.45%, and its share of the global population, which was approximately 16% to 17% during the mid-2000s.

The primary source of these resources is the annual precipitation received by the country, totaling nearly 4,000 km³. Despite this volume, topographical and hydrological limitations mean that the total utilizable water resource is about 1,123 km³, comprising 690 km³ of surface water and 433 km³ of replenishable groundwater. The 4% statistic is the standard value used in national geographic records and educational curricula to describe India's standing in global hydrology.

Explanation

Arunachal Pradesh shares the longest international boundary with Myanmar, spanning approximately 520 km. This mountainous border follows the natural geographic divide formed by the Patkai Bum and other high ranges that separate the drainage basins of the Brahmaputra and Irrawaddy rivers. Of the total 1,643 km long border that India shares with Myanmar across four northeastern states, Arunachal Pradesh possesses the most extensive segment. The terrain along this border is characterized by dense forests and rugged topographical features.

Explanation

The Power Pack project is a decentralized solar electrification initiative designed to provide electricity to remote and inaccessible rural areas where extending the conventional power grid is not techno-economically feasible. This project utilizes standalone Solar Photovoltaic (SPV) systems, which typically consist of solar modules, battery banks, and charge controllers. These units are installed in isolated hamlets or individual households to provide a reliable source of power for basic needs such as lighting and operating small electronic devices. In India, such programs have been instrumental in the electrification of far-flung regions, particularly in states like Rajasthan, by leveraging renewable energy to bridge the gap in rural energy access.

Explanation

The Universal Product Code (UPC) is a barcode symbology widely used for tracking trade items in retail stores. Developed in the early 1970s, it consists of a unique 12-digit number represented by a series of black bars and white spaces of varying widths. When these bars are scanned by an optical sensor at a point-of-sale terminal, they are converted into digital data that allows a computer to identify the specific product, its price, and other inventory details instantly. This system facilitates efficient checkout processes and automated stock management in the global supply chain.

Explanation

This followed the victory of the DMK-led alliance in the 2006 Tamil Nadu Legislative Assembly elections. His previous tenures in the office were from 1969 to 1971, 1971 to 1976, 1989 to 1991, and 1996 to 2001. As of the year 2007, he was serving his fifth term as the head of the state government.

Explanation

In June 2007, the World Bank approved a 600 million dollar financing package—comprising a 300 million dollar IBRD loan and a 300 million dollar concessional IDA credit—to support the Strengthening Rural Credit Cooperatives Project in India. This project was designed to implement the reform package recommended by the Vaidyanathan Committee for the revival of the Short-term Cooperative Credit Structure (STCCS). By revitalizing these institutions and making them financially viable and professional, the initiative aimed to ensure a sustainable and increased flow of credit to farmers. This enhanced access to formal finance was a critical strategic move to help farmers invest in better inputs and technology, thereby directly strengthening agricultural production and improving the growth rate of the rural economy.

Explanation

Dayaldas Sindhayach was a prominent court historian and poet under the patronage of Maharaja Ratan Singh of Bikaner. He authored the significant historical chronicle known as Dayaldas ri Khyat, which is commonly titled as Bikaner re Rathora ri Khyat or the history and fame of the Rathores of Bikaner. The work consists of two major parts, where the second part is dedicated entirely to the genealogical history, administrative developments, and the military achievements of the Rathore rulers of the Bikaner state. Starting from the foundation of the kingdom by Rao Bika, the text provides a continuous narrative up to the mid-19th century. Written in the traditional Rajasthani prose style, it is regarded as a primary historical source for the region's medieval and early modern history.

Explanation

Ajrakh print is an ancient and intricate form of block printing that is traditionally associated with the Barmer district of Rajasthan. This craft is distinguished by its use of complex geometric patterns and a specific color palette dominated by indigo blue and madder red, derived from natural dyes. The process involves a unique resist-printing technique where the fabric undergoes multiple stages of washing, printing, and dyeing. In the context of Rajasthan's textile heritage, Barmer is the primary center for this art form, practiced largely by the Khatri community who have maintained the traditional methods of hand-block printing for centuries.

Explanation

The excess pressure ΔP inside a soap bubble is determined by the Young-Laplace equation, ΔP = 4T/r, where T is the surface tension of the liquid and r is the radius of the bubble. This relationship shows that the pressure inside a bubble is inversely proportional to its radius. Therefore, a smaller bubble with a smaller radius possesses a higher internal pressure compared to a larger bubble. When the two bubbles are connected by a tube, the pressure gradient causes air to flow from the region of higher pressure to the region of lower pressure. Specifically, air moves from the smaller bubble into the larger bubble. As the smaller bubble loses air, its radius decreases further, which in turn increases its internal pressure even more. Conversely, the larger bubble expands as it receives air, leading to a decrease in its internal pressure. This process continues until the smaller bubble essentially empties its contents into the larger one, causing the smaller bubble to shrink and the larger bubble to grow.

Explanation

Gulab Nabi Azad contested the by-election for the Bhaderwah assembly seat in Jammu and Kashmir in April 2006. Having assumed the office of Chief Minister in November 2005 while being a member of the Rajya Sabha, he was required to be elected to the state Legislative Assembly within six months to continue in his post. In the resulting by-poll, he achieved a record-breaking victory by securing 62,078 votes out of the total 65,992 valid votes polled. This overwhelming support accounted for approximately 94 percent of the total votes cast in the constituency, confirming his massive popularity and fulfilling the constitutional requirement for his chief ministership.

Explanation

Rajasthan possesses a vast and unique cultural heritage including historical forts, palaces, vibrant festivals, and folk traditions, alongside a diverse geographical landscape ranging from the Thar Desert to the Aravalli hills. Tourism serves as a natural policy priority because it is an environmentally sustainable sector that requires relatively low water consumption compared to other economic activities in a water-scarce state. Furthermore, tourism fosters inclusive development by generating widespread, labor-intensive employment for local communities, including rural artisans, guides, and small-scale service providers, thereby distributing economic benefits across various social strata and geographical regions without depleting natural resources.

Explanation

The sensation of sound persists in the human brain for approximately 0.1 seconds, which is known as the persistence of hearing. For an echo to be heard distinctly, the reflected sound must reach the ear after this 0.1 second interval. At a standard room temperature of about 22°C, the speed of sound in air is approximately 344 m/s. Using the formula Distance = Speed × Time, the total distance traveled by the sound from the source to the obstacle and back must be at least 344 m/s × 0.1 s = 34.4 meters. To find the minimum distance to the reflecting surface, this total distance is divided by two, resulting in 17.2 meters. Standard educational texts typically approximate this value to 17 meters.

Explanation

The fraction of a radioactive substance remaining after time t is determined by the formula N = N₀(1/2)ⁿ, where n is the number of half-lives that have passed (n = t / T₁/₂). Given a half-life T₁/₂ of 10 days, a period of 20 days corresponds to n = 20 / 10 = 2 half-lives. Substituting this into the decay equation, the amount remaining is N = N₀(1/2)² = N₀ / 4. The amount of the substance that has decayed is the difference between the initial amount and the remaining amount, which is N₀ - N₀ / 4 = 3/4 N₀. Therefore, exactly 3/4 of the substance decays over the course of 20 days.

Explanation

The Indira Gandhi Canal, originally known as the Rajasthan Canal, originates from the Harike Barrage. This barrage is located at the confluence of the Sutlej and Beas (Vyas) rivers in the state of Punjab. Construction of the canal system began in 1958 to provide irrigation and drinking water to the arid regions of the Thar Desert in northwestern Rajasthan. By tapping into the surplus waters of these Himalayan rivers, the project transformed vast tracts of wasteland into productive agricultural land, supporting the cultivation of crops like wheat, mustard, and cotton in an otherwise desert environment.

Explanation

In the arid and semi-arid regions of western Rajasthan, the rate of evaporation significantly exceeds the rate of precipitation. This climatic imbalance triggers capillary action, where moisture from the lower layers of the soil moves upward through narrow soil pores or capillary cells toward the surface. As this water rises, it carries dissolved mineral salts such as sodium, calcium, and magnesium carbonates and chlorides from the subsoil. Upon reaching the surface, the water evaporates, leaving these salts deposited in the topsoil. This continuous accumulation of basic cations leads to the development of saline and alkaline soil characteristics, often resulting in the formation of a hard salt crust on the land surface.

Explanation

The Chambal Valley Project is a multi-purpose scheme developed jointly by the governments of Rajasthan and Madhya Pradesh to harness the water of the Chambal River. The Rana Pratap Sagar Dam is located at Rawatbhata in the Chittorgarh district of Rajasthan and was commissioned in 1970 as the second stage of the project. The Jawahar Sagar Dam is situated approximately 26 kilometers downstream from the Rana Pratap Sagar Dam in the Kota district of Rajasthan. Both of these dams are major components of the project's infrastructure built within the geographical boundaries of Rajasthan for the purpose of irrigation and hydroelectric power generation.

Explanation

Nagaur district in Rajasthan is renowned globally for the cultivation of a specific variety of fragrant fenugreek known as Nagauri Pan Methi or Kasuri Methi. The unique soil and climatic conditions of this region impart a distinct and intense aroma to the crop, which is highly valued in culinary applications across India and international markets. Nagaur is one of the largest producers of this fragrant herb, and the leaves are typically dried and processed for trade, contributing significantly to the local agricultural economy and making the district synonymous with high-quality fenugreek production.

Explanation

The filament of an incandescent electric bulb is typically made of tungsten because of its extremely high melting point, which is approximately 3422°C. To produce visible light, the filament must be heated to a state of incandescence through resistive heating as electric current passes through it. In standard commercial incandescent lamps, the operating temperature of the filament generally falls within the range of 2000°C to 2500°C. This temperature is high enough to emit a sufficient amount of visible light while being low enough to prevent the tungsten from sublimating rapidly, which would otherwise darken the glass envelope and cause the filament to break prematurely.

Explanation

Jayasimha Suri was a distinguished 13th-century Jain scholar and poet associated with the Vaghela court in Gujarat. He authored the Sanskrit historical drama titled Hammira-mada-mardana, which translates to the crushing of the pride of Hammira. The play serves as a panegyric for the Vaghela ruler Viradhavala and his ministers, Vastupala and Tejahpala, highlighting their strategic prowess in repelling an invasion by the forces of the Delhi Sultanate, represented by the title Hammira. Written in the early 13th century, this work provides valuable insights into the political climate and the resistance offered by regional Indian kingdoms against external conquests during the medieval era.

Explanation

Vasundhara Raje was conferred with the United Nations Women Together Award in 2007 for her significant contributions toward women's empowerment and social development during her tenure as the Chief Minister of Rajasthan. The award recognized her leadership in implementing effective policies for the socio-economic upliftment of women, particularly through the promotion of self-help groups and the Amrita project, which helped rural women market their products. She received the award at a ceremony held at the United Nations headquarters in New York, marking her as the first Indian woman to receive this international honor for excellence in the field of gender equality and poverty eradication.

Explanation

The designation of Rajapramukh was replaced by the office of the Governor through the 7th Constitutional Amendment Act of 1956. This amendment implemented the recommendations of the States Reorganisation Commission, which led to the abolition of the four-fold classification of states into Part A, B, C, and D. Prior to this, Rajapramukhs served as the constitutional heads of Part B states, which were primarily composed of former princely states. By removing the distinction between different categories of states and abolishing the post of Rajapramukh, the Act ensured a uniform administrative structure where every state in India would be headed by a Governor appointed by the President.

Explanation

The height h to which a liquid rises in a capillary tube is determined by Jurin's Law, which is expressed by the formula:

h = 2T cos θ / (rρg)

In this formula, T represents the surface tension of the liquid, θ is the contact angle between the liquid and the tube wall, r is the internal radius of the capillary tube, ρ is the density of the liquid, and g is the acceleration due to gravity.

According to this relationship, the height of the liquid column is directly proportional to the surface tension (h ∝ T) and inversely proportional to the density of the liquid (h ∝ 1/ρ). Assuming the radius of the tube and the acceleration due to gravity remain constant, a liquid will rise to a greater height than water if its surface tension is higher or its density is significantly lower. In the context of the provided options, the most direct reason for a greater height of rise is that the liquid possesses a greater surface tension than water, which increases the upward force along the meniscus to support a taller column of liquid. Since water already has a very low contact angle with glass (cos θ ≈ 1), increasing the surface tension is the primary way to increase the capillary rise height h.

Explanation

The President (Discharge of Functions) Act, 1969, provides that in the event of a vacancy in the offices of both the President and the Vice-President, the Chief Justice of India shall discharge the functions of the President. This legislation was enacted by Parliament under the authority of Article 70 of the Constitution of India, which allows for provisions to be made for the discharge of presidential functions in contingencies not otherwise provided for. If the Chief Justice of India is also unavailable, the responsibility falls to the senior-most judge of the Supreme Court who is available. This protocol ensures the continuity of the executive head of state. A historical instance of this occurred in 1969 when Justice M. Hidayatullah, the then Chief Justice of India, discharged the duties of the President after the death of President Zakir Hussain and the resignation of Vice-President V.V. Giri.

Explanation

A Writer's People: Ways of Looking and Feeling, published in 2007, is a non-fiction work where V.S. Naipaul explores the literature and personalities that influenced his worldview. In the essays concerning India, Naipaul offers a critical assessment of the country's intellectual and spiritual heritage. He characterizes Vinoba Bhave, the disciple of Mahatma Gandhi and leader of the Bhoodan movement, as a holy fool. This description reflects Naipaul's skepticism toward Bhave's asceticism and the Bhoodan movement's focus on moral persuasion for land reform. Naipaul argues that Bhave represented a regressive form of Indian thought that relied on religious symbolism rather than concrete political or economic development to address social inequality.

Explanation

According to the 2001 Census of India, which was the most recent data available in 2007, Bengali is the second most spoken language in the country after Hindi. It is spoken by approximately 8.11 percent of the total population, accounting for over 83 million speakers. This demographic standing makes it the most widely spoken language among the choices provided.

Explanation

The National Rural Employment Guarantee Act (NREGA), enacted in 2005, represents a fundamental shift from previous employment programs because it is a demand-driven legislative framework rather than a supply-driven administrative scheme. By being a legal provision, it confers a justiciable right to work upon rural households. This statutory backing ensures that the state is legally mandated to provide at least 100 days of guaranteed wage employment in a financial year to every household whose adult members volunteer to do unskilled manual work. Unlike earlier schemes which depended on budget allocations and administrative discretion, NREGA makes the provision of employment a matter of right for the citizen, where the failure of the government to provide work within 15 days of demand results in a legal obligation to pay an unemployment allowance.

Explanation

Sirohi district is located in the southwestern region of Rajasthan and shares its northern and northeastern boundaries with Pali district. Pali is a centrally located district that serves as a geographical hub, sharing borders with eight different districts. To the north of Pali lies Nagaur district, which shares a direct boundary with the northern part of Pali. This geographical positioning establishes a contiguous chain where each district in the group shares a border with the next. Specifically, the northern border of Sirohi meets the southern border of Pali, and the northern border of Pali meets the southern border of Nagaur, forming a continuous sequence of administrative divisions across the state.

Explanation

The Sethusamudram Shipping Canal Project is designed to create a continuous navigable sea route around the Indian peninsula by dredging a channel through the Palk Strait and the Gulf of Mannar. According to the project specifications released by the Government of India and the Tuticorin Port Trust at the time of the project's inception in 2005, the total length of the canal is 167 kilometers. This alignment is intended to connect the Bay of Bengal and the Arabian Sea, allowing ships to avoid circumnavigating Sri Lanka and thereby reducing travel distance by approximately 350 to 425 nautical miles. The canal depth is planned at 12 meters to accommodate vessels with a draft of up to 10 meters.

Explanation

The Committee to Review Arrangements For Institutional Credit for Agriculture and Rural Development, commonly known as CRAFICARD, was established by the Reserve Bank of India in March 1979 under the chairmanship of Shri B. Sivaraman. The committee was tasked with evaluating the existing institutional arrangements for providing credit to the agricultural and rural sectors and suggesting improvements to ensure that credit reached the intended beneficiaries effectively. The findings and recommendations presented in the CRAFICARD report highlighted the need for a specialized apex organization to coordinate and manage the credit requirements of the rural economy. This recommendation directly led to the enactment of the National Bank for Agriculture and Rural Development Act and the subsequent establishment of NABARD on July 12, 1982, to serve as the lead agency for rural development and credit flow in India.

Explanation

The Ganga Canal, specifically the Upper Ganga Canal, is recognized as one of the oldest and most extensively developed irrigation systems in the world. Its construction was initiated in 1842 under the supervision of the British engineer Colonel Proby Cautley and it was officially opened in 1854. At the time of its completion, it was considered a masterpiece of engineering, featuring a main channel length of over 560 kilometers and a vast network of distributaries totaling thousands of kilometers. The system was designed to irrigate the fertile Doab region between the Ganges and Yamuna rivers, providing water to approximately 9000 square kilometers of agricultural land. The inclusion of complex structures like the Solani Aqueduct at Roorkee demonstrated a level of hydraulic engineering that was unprecedented in the 19th century, establishing it as a pioneering model for modern large-scale canal projects globally.

Explanation

The term columnar cells in this context refers to stem cells, which are characterized by their ability to undergo self-renewal and differentiate into various specialized cell types. The assertion that these cells are only found in the embryo is incorrect because stem cells exist in living organisms at all stages of development. While embryonic stem cells are derived from the early-stage embryo, adult stem cells (also known as somatic stem cells) are found in many post-natal tissues, including bone marrow, the brain, blood vessels, skeletal muscle, skin, and the liver. These adult stem cells remain in a quiescent state until they are activated by tissue injury or disease, at which point they proliferate and differentiate to repair and maintain the specific organs in which they are located throughout the life of the organism.

Explanation

The Indian Postal Department issued a commemorative postage stamp with a face value of five rupees on 2 September 1992, specifically featuring the Phad of Lord Devnarayan. Devnarayanji is a revered folk deity in Rajasthan, especially within the Gurjar community. His Phad is historically significant as it is considered the oldest, longest, and most detailed among all the traditional folk scroll paintings of the region. The issuance of the stamp served to recognize the cultural importance of Phad art, a traditional form of visual storytelling where the life and heroic deeds of the deity are painted on a long cloth and narrated through folk songs.

Explanation

Leta, Mangrol, and Salawas are significant traditional handloom clusters in Rajasthan specialized in the weaving of textile items. Leta, situated in the Jalore district, is famous for its hand-woven Khes, which are heavy cotton bedspreads or blankets characterized by traditional geometric patterns. Mangrol in the Baran district is a major hub for handloom weaving, particularly known for producing fine cotton and blended fabrics within the Hadoti region. Salawas, located in the Jodhpur district, is internationally renowned for its flat-woven rugs known as Salawas Durries. These durries are crafted by local artisans using cotton or wool on traditional looms, often featuring intricate designs that reflect the cultural heritage of the Marwar region. All three locations are recognized as key centers where the craft of manual weaving has been preserved and promoted through generations.

Explanation

Fashion for Development is a concept that utilizes the fashion industry as a tool for poverty alleviation and sustainable economic growth. In the context of mid-2000s initiatives in India, particularly in states like Rajasthan, this program focused on revitalizing traditional handloom sectors. By involving prominent fashion designers to modernize the appeal of heritage fabrics like Khadi and Kota Doria, the initiative aimed to create a global market for these textiles. This strategy ensures that rural weavers and artisans receive better remuneration and consistent employment, thereby linking traditional craftsmanship with the mainstream economy to achieve socio-economic development.

Explanation

Sem refers to the environmental condition of waterlogging and subsequent soil salinity, frequently observed in the canal-irrigated regions of Rajasthan, Punjab, and Haryana. It occurs when the groundwater table rises close to the surface due to excessive irrigation, poor drainage, and seepage from canals. This rise in the water table saturates the root zone of plants and brings underground salts to the surface through capillary action. These physical and chemical modifications result in significant changes in the ecosystem, as the affected land loses its original productivity and native vegetation, transforming into a saline or marshy habitat that no longer supports the previous biodiversity.

Explanation

Sewan grass, scientifically known as Lasiurus scindicus, is a highly nutritious fodder grass naturally occurring in the extremely arid regions of Western Rajasthan. It is predominantly found in the Jaisalmer district, particularly within the Lathi series area, where it thrives in deep sandy soils and very low rainfall conditions. Alwar district is situated in the northeastern part of Rajasthan and falls under a semi-arid to sub-humid climatic zone, which does not support the natural growth of this specific desert grass species. This geographical mismatch makes the pairing of Sewan grass with Alwar incorrect.

Explanation

In April 2007, Aristides Gomes, the Prime Minister of Guinea-Bissau, accused the Indian Ambassador, Parbati Sen Vyas, of interfering in the internal political affairs of his country. Gomes, who was forced to resign after losing a vote of confidence in the National Assembly, wrote a letter to the Indian Prime Minister, Manmohan Singh, alleging that the ambassador played a significant role in the political instability that led to the downfall of his government.

The accusation was linked to commercial interests involving a $25 million project funded by an Indian Line of Credit (LoC). Gomes alleged that the diplomat had pressured his administration to award a power project contract to a specific Indian firm, Mohan Energy Corporation, and that the ambassador had colluded with political opponents to destabilize his government when he resisted. Parbati Sen Vyas, who was the Ambassador of India to Senegal and concurrently accredited to Guinea-Bissau, denied the allegations, which were later investigated by the Indian Ministry of External Affairs.

Explanation

The Chakwada incident, which took place in the Jaipur district of Rajasthan around 2001-2002, was a significant social conflict centered on the right of Dalits to access a public pond or reservoir. In the village of Chakwada, the upper-caste community had historically restricted the use of the main village pond, prohibiting Dalits from bathing in or using its water. When Dalit activists and local residents challenged this practice by asserting their constitutional right to use public facilities, it led to a tense standoff and large-scale mobilization. The incident highlighted the persistence of untouchability and caste-based discrimination regarding communal water resources in rural Rajasthan, eventually requiring state intervention to ensure that all citizens could use the public reservoir regardless of their caste.

Explanation

The Gavri folk-drama, often referred to as Gauri dance, is a traditional performance of the Bhil tribe in the Mewar region of Rajasthan. It is a ritualistic dance-drama performed over forty days following the Raksha Bandhan festival, dedicated to the worship of Lord Shiva and Goddess Parvati. The performance relies on a specific narrative structure involving two primary roles. The Jhamatya is the character who recites the poetry and tells the story in the local dialect, acting as the lead narrator. The Khatkadiya, also known as Kutkudiya, serves as the comedic counterpart who repeats the lines spoken by the Jhamatya to ensure the audience follows the plot while simultaneously performing as a joker. Through his humorous gestures and witty repetition, the Khatkadiya provides comic relief and maintains the engagement of the spectators throughout the traditional sequence of events.

Explanation

Huen Tsang, the renowned Chinese Buddhist monk and traveler, visited Bhinmal in Rajasthan during his extensive travels across India in the 7th century. In his travelogue, Si-Yu-Ki, he referred to the city as Pi-lo-mo-lo. At the time of his visit around 641 AD, Bhinmal served as the capital of the Gurjaradesa kingdom under the Gurjara-Pratihara dynasty. He described the city as a major center of learning and trade, providing significant historical documentation regarding the socio-political and religious conditions of northern and western India during the reign of Emperor Harshavardhana.

Explanation

Hanuman Garh Junction is situated in the basin of the Ghaggar River in northern Rajasthan. Due to the continuous deposition of silt and sediment over long periods, the bed of the Ghaggar River has gradually risen to an elevation that is higher than the ground level of the town itself. This topographical feature means that the residential areas of Hanuman Garh Junction lie at a lower altitude compared to the adjacent river channel. Consequently, the town faces a high risk of inundation and severe flooding whenever the Ghaggar River carries excess water from its catchment areas in the Shivalik Hills.

Explanation

The Tharparkar cattle breed is indigenous to the arid regions of the Thar Desert. Its native tract spans the Tharparkar district in Sindh, Pakistan, and extends directly into the western border districts of Rajasthan, specifically Jaisalmer, Barmer, and portions of Bikaner and Jodhpur. This breed is exceptionally well-adapted to the extreme climatic conditions of the desert borderlands, characterized by high temperatures and scarce water resources. It is valued as a dual-purpose animal, known for its high milk yield and its capacity for heavy work as a draught animal in the sandy terrain of the Rajasthan-Pakistan border area.

Explanation

The Rana Pratap Sagar Dam is the second major dam constructed on the Chambal River, located at Rawatbhata in the Chittorgarh district of Rajasthan.

Explanation

Oxytocin is a peptide hormone synthesized in the hypothalamus by the paraventricular and supraoptic nuclei. It travels down the nerve fibers to the posterior lobe of the pituitary gland, also known as the neurohypophysis, where it is stored in the axon terminals. In response to physiological stimuli, such as an infant suckling at the nipple, the posterior pituitary gland secretes oxytocin into the bloodstream. This hormone then targets the myoepithelial cells surrounding the alveoli of the mammary glands, causing them to contract and force milk into the duct system for ejection. This process is commonly referred to as the milk let-down reflex.

The Lathi series is a significant geological formation located in the Jaisalmer district of Rajasthan, primarily consisting of Jurassic-age sandstone, siltstone, and conglomerates. It is characterized as a geological water channel or a prolific underground aquifer that stretches between Jaisalmer, Pokaran, and Barmer. This formation is renowned for holding substantial reserves of high-quality groundwater in an otherwise arid desert environment. Scientific studies and satellite imagery have often associated this specific geological belt with the palaeochannels of the ancient Saraswati River, suggesting that the subterranean water found here is part of a prehistoric fluvial system that continues to provide a reliable water source for the region.

Explanation

Kota entered into a treaty of Subordinate Alliance with the British East India Company on December 26, 1817. This occurred during the administration of Governor-General Lord Hastings, who aimed to bring the Rajput states under British protection to eliminate the threat of the Pindaris and the Marathas. The treaty was negotiated between Charles Metcalfe and the regent of Kota, Zalim Singh. Under the terms of the agreement, the British guaranteed the protection of the state in exchange for Kota's acceptance of British suzerainty and the payment of tribute. This treaty established Kota as the first major state to formalize a subordinate relationship with the British in this phase of diplomatic expansion, following the initial agreement signed by Karauli in November 1817.

Explanation

The Dodo (Raphus cucullatus) was a flightless bird endemic to the island of Mauritius, located in the Indian Ocean east of Madagascar. It was first documented by Dutch sailors in 1598 and became extinct less than a century later, around the late 1600s. The extinction was a direct result of human activity, including hunting by sailors and the introduction of invasive species such as pigs, rats, and macaques, which predated on Dodo eggs and competed for food. Having evolved in an environment without natural predators, the Dodo lacked any defensive behaviors or the ability to fly, making it uniquely vulnerable to these new threats. It has since become a global symbol of human-induced extinction.

Its combination of vast reserves and high metal concentration makes it the premier geological site for lead and zinc in the region.

Explanation

The shape of a candle flame on Earth is determined by natural convection. As the flame heats the surrounding air, the air becomes less dense and rises due to the buoyancy force, which is calculated as F₆ = Vρg. This upward movement of hot gases and the simultaneous influx of cooler, denser air from the bottom stretches the flame into its familiar teardrop shape.

In a state of weightlessness or microgravity, the gravitational acceleration g is effectively zero, which eliminates buoyancy-driven convection (F₆ ≈ 0). In the absence of these rising air currents, the transport of oxygen to the flame and the dispersal of combustion products occur solely through molecular diffusion. Since diffusion is an isotropic process—meaning it occurs at an equal rate in all directions from the wick—the combustion zone stabilizes into a spherical shape. This results in a flame that is dim, blue, and perfectly round, as the fuel and oxygen react in a uniform radial pattern.

Explanation

Bhogi Lal Pandya was a prominent social reformer and freedom fighter from the Dungarpur region of Rajasthan. He dedicated his life to the upliftment of the tribal communities and the underprivileged in the Vagad or Bagad region, which encompasses the districts of Dungarpur and Banswara.

The Ghateshwara Mahadeva temple, the most prominent in the group, exhibits the characteristic Nagara features such as a sanctum sanctorum and a pillared portico, reflecting the evolution of North Indian temple architecture during the early medieval period.

Explanation

Helium is mixed with oxygen for deep-sea diving to prevent nitrogen narcosis and decompression sickness. At high pressures, nitrogen dissolves into the blood and tissues, acting as an anesthetic that impairs a diver's judgment and motor skills. Helium is significantly less soluble in human blood and fatty tissues than nitrogen, which reduces the amount of gas absorbed under pressure. Furthermore, helium has a much lower density, which decreases the respiratory effort required to breathe the compressed gas at great depths where gases become denser.

Explanation

The Maski Minor Rock Edict, located in the Raichur district of Karnataka, is historically significant because it was the first inscription found that explicitly mentions the personal name Ashoka. Before its discovery by C. Beadon in 1915, the emperor was primarily identified in his inscriptions by the titles Devanampiya and Piyadasi. The text of the Maski edict begins with the phrase Devanampiyasa Asokasa, providing the crucial epigraphic evidence needed to definitively link the King Ashoka described in Buddhist chronicles and the Puranas with the ruler responsible for the widespread rock and pillar edicts across the Indian subcontinent.

Explanation

The Big Bang Theory is the prevailing cosmological model that explains the origin and evolution of the universe. It posits that the universe began from an extremely hot and dense state known as a singularity approximately 13.8 billion years ago. Since that initial moment, the universe has been continuously expanding and cooling. This theory is supported by significant scientific evidence, including the observation of galactic redshift by Edwin Hubble, which shows that galaxies are moving away from each other, and the detection of Cosmic Microwave Background Radiation, which is the thermal remnant of the early universe. These observations confirm that the universe had a definitive beginning and has evolved over billions of years into its current state.

Explanation

According to Archimedes' Principle, a floating object displaces a weight of fluid equal to its own weight. If an ice cube of weight W floats in water, it displaces a volume of water V_d such that W = V_d ⋅ ρ_w ⋅ g, where ρ_w is the density of water and g is the acceleration due to gravity. When the ice cube melts, it turns into liquid water with the same mass and weight W. The volume Vₘ occupied by this resulting meltwater is calculated as Vₘ = W/(ρ_w ⋅ g). Because the weight of the ice and the density of the surrounding water are the same in both states, Vₘ is identical to V_d. The volume of water produced by the melting ice exactly fills the volume that the ice cube displaced while floating.

Explanation

The Ghaggar is an ephemeral river in India that flows during the monsoon season. Originating in the Shivalik Hills of Himachal Pradesh, it passes through Haryana and enters Rajasthan through Hanumangarh district. During periods of heavy rainfall or when the river is in spate, its discharge increases significantly, allowing the water to flow beyond its usual termination points near Anupgarh. In such high-flood conditions, the river bed continues across the international border into the Bahawalpur region of Pakistan, where it is known as the Hakra River. Historically, these floodwaters have been documented to reach as far as Fort Abbas in Pakistan, which serves as a notable landmark along the ancient dry bed of the Hakra.

Explanation

The state also holds the top rank in groundnut (peanuts) production, which is a major oilseed crop for the region. Due to its extensive coastline and the unique environment of the Rann of Kutch, Gujarat accounts for nearly three-quarters of India's total salt production. In the dairy sector, Gujarat is a dominant producer and the heart of the cooperative dairy movement in India, maintaining a high rank in milk production and processing capacity.

Explanation

The Rajasthan Fiscal Responsibility and Budget Management Act was enacted in 2005, following the framework of the Central FRBM Act of 2003, to institutionalize financial discipline within the state's governance. Its primary purpose is to ensure long-term macro-economic stability by making the government responsible for maintaining a sustainable debt level and reducing fiscal imbalances. The Act mandates the state government to take appropriate measures to eliminate the revenue deficit and progressively reduce the fiscal deficit to a manageable percentage of the Gross State Domestic Product. By setting statutory targets and requiring the presentation of medium-term fiscal policy statements, it enforces transparency in fiscal operations and ensures that the government remains accountable for its expenditure and borrowing patterns. This legislative framework was also a prerequisite for states to avail themselves of debt relief and interest rate benefits recommended by the Twelfth Finance Commission.

Explanation

The Bhoomi Poratam movement was a major land struggle launched in 2007 in Andhra Pradesh by the Communist Party of India (Marxist) and the Communist Party of India. The joint movement aimed to address the long-standing issue of landlessness by demanding the implementation of the Koneru Rangarao Committee recommendations. The Communist parties identified surplus government and private lands that were being held in violation of land ceiling laws and organized the landless poor to occupy these plots. This agitation was centered on the demand for house sites and cultivable land for Dalits, tribals, and other marginalized groups, leading to large-scale protests and state-wide demonstrations against the then-incumbent state government.

Explanation

The 73rd Constitutional Amendment Act of 1992 accorded constitutional status to the Panchayati Raj Institutions by inserting Part IX into the Constitution of India. This part is titled The Panchayats and consists of provisions ranging from Article 243 to Article 243O. Article 243 specifically provides definitions and establishes the framework for the three-tier system of local self-government at the village, intermediate, and district levels. This constitutional recognition transitioned Panchayats from the discretionary provisions of the Directive Principles of State Policy under Article 40 to a mandatory statutory requirement for all states, ensuring regular elections, fixed tenures, and the devolution of powers and responsibilities for economic development and social justice.

Explanation

Atmospheric refraction causes the sun to be visible to an observer about two minutes before the actual sunrise. When the sun is still slightly below the horizon, the light rays emanating from it enter the Earth's atmosphere and travel through layers of air that become increasingly dense closer to the surface. As light moves from the vacuum of space into these denser atmospheric layers, it undergoes continuous refraction and bends towards the normal. This downward bending of light rays makes the sun appear at a higher position than its true geometric location. To an observer on the ground, the sun appears to have already crossed the horizon because the human eye perceives light as traveling in a straight line from the direction of its final entry. This phenomenon creates an apparent vertical shift of approximately 0.5 degrees in the position of the sun.

Explanation

Plaster of Paris is chemically known as calcium sulfate hemihydrate, with the chemical formula CaSO₄ · 1/2H₂O. It is obtained by heating gypsum, which is calcium sulfate dihydrate (CaSO₄ · 2H₂O), to a specific temperature of approximately 373 K (100°C). At this temperature, gypsum loses three-fourths of its water of crystallization, resulting in the formation of the hemihydrate. The substance is called Plaster of Paris because it was originally prepared by heating gypsum found in large quantities near Paris. When Plaster of Paris is mixed with water, it rehydrates and sets into a hard, solid mass of gypsum within a few minutes, a property that makes it essential for supporting fractured bones in medical casts and for creating molds in sculpture and architecture.

Explanation

Taragarh Fort in Ajmer is popularly known as Garhbeetheli because it is constructed on the Bitli hill of the Aravalli range. The fort was originally founded by the Chauhan ruler Ajaypal in the 7th century and served as a strategic military outpost throughout various dynasties, including the Mughals and Marathas. Due to its imposing structure on the steep hillside and its historical significance as a key defensive position in central Rajasthan, it was famously described as the Gibraltar of Rajasthan by Bishop Heber. The name Garhbeetheli is derived directly from the specific hill, Bitli, upon which the fortifications are situated.

This resolution recognized the representatives of the PRC government as the only legitimate representatives of China to the United Nations and expelled the representatives of the Republic of China (Taiwan) from the seat they had occupied since 1945. The vote reflected a major shift in international diplomacy, as the PRC took over China's permanent seat on the UN Security Council and all other UN organs.

Explanation

Rajasthan Rashtriya Chemicals and Fertilizers Limited (RRCFL) is a joint venture project established by Rashtriya Chemicals and Fertilizers Limited (a Government of India undertaking) and Rajasthan State Mines and Minerals Limited (a Government of Rajasthan undertaking). The chemical plant was set up at Kapasan in the Chittorgarh district for the production of Di-Ammonium Phosphate (DAP) fertilizer. The location was strategically selected to utilize the rock phosphate sourced from the Jhamarkotra mines in the nearby Udaipur district, which provides the essential raw material for the manufacturing unit.

Explanation

The standard temperature conversion formula is F = 9/5C + 32. The question asks at what point the Fahrenheit temperature is twice the Celsius temperature, meaning the condition is C = 2F. Substituting into the conversion formula: F = 9/5(2F) + 32, which gives F = 18F/5 + 32. Multiplying through by 5 yields 5F = 18F + 160, so -13F = 160 and F = -160/13 ≈ -12.3°F. The corresponding Celsius value is C = 2 × (-12.3) ≈ -24.6°C. Verification using the conversion formula: 9/5(-24.6) + 32 = -44.3 + 32 = -12.3°F, confirming that the Celsius reading is exactly twice the Fahrenheit reading at this temperature.

Explanation

Talwar Bandhai was a traditional succession tax or feudal fee prevalent in the princely states of Rajputana. It was charged by the state ruler from a new Jagirdar or landlord when they inherited a fief and took over the administration of their estate. The name refers to the ceremony of tying the sword, symbolizing the formal assumption of power and the landlord's loyalty to the sovereign ruler. This fee served as both a source of state revenue and a formal legal recognition of the heir's right to the jagir. In various Rajasthan states, this practice was also known by names such as Hukum-nama, Nazrana, or Quaid-lagan. The imposition of this tax was a significant socio-political issue, notably acting as a trigger for the Bijolia Peasant Movement in 1906 when the Jagirdar attempted to recover the fee amount from the farmers.
