MPSC Prelims 2006 General Studies Paper I with Answers & Explanations

Explanation

Raghunath Dhondo Karve pioneered the family planning and birth control movement in Maharashtra and India. He established the first birth control clinic in Mumbai in 1921 to provide scientific guidance on contraception and reproductive health. Karve dedicated his life to advocating for sex education, women's health, and population control, famously publishing the monthly Marathi magazine Samaj Swasthya from 1927 to spread awareness and challenge conservative societal norms regarding family planning.

Explanation

The uprising of 1857, also known as the First War of Indian Independence, was a widespread rebellion against British East India Company rule that concentrated heavily across northern and central India. Meerut served as the initial flashpoint where the sepoy mutiny broke out on May 10, 1857. In Jhansi, Rani Lakshmibai led a fierce resistance against the British after her kingdom was annexed under the Doctrine of Lapse. Kanpur became a major center under the leadership of Nana Sahib, Rao Sahib, and Tatya Tope. Lucknow was another crucial stronghold where Begum Hazrat Mahal led the forces during the prolonged Siege of Lucknow. These four locations represent the most prominent and intensely active military centers of the rebellion.

Explanation

Gopal Hari Deshmukh was a prominent social reformer, thinker, and writer from Maharashtra who wrote under the pen name Lokhitwadi, which translates to advocate for the welfare of the people. He published a highly influential series of 108 essays known as Shatapatre in the weekly Marathi newspaper Prabhakar between 1848 and 1850. Through these writings, he criticized the orthodox and superstitious practices of Hindu society, advocated for female education, strongly opposed the rigid caste system, and promoted rationalism, science, and modern education as essential elements for social progress and national self-reliance.

Explanation

Dadabhai Naoroji, widely regarded as the Grand Old Man of India, authored the classic work Poverty and un-British Rule in India, published in 1901. In this book, he formulated and detailed the Drain of Wealth theory, which systematically exposed how British colonial policies drained India's economic resources and wealth to Britain. He argued that this continuous economic drain, occurring through mechanisms like home charges, military expenses, and unilateral transfer of funds without any equivalent return, was the fundamental cause of the extreme poverty and recurring famines in India.

Explanation

The Bombay Plan of 1944, officially titled "A Brief Memorandum Outline of a Plan of Economic Development for India," was a proposal for the development of the post-independence economy of India. Formulated by eight leading Indian industrialists, including J.R.D. Tata, G.D. Birla, and Ardeshir Dalal, the plan first envisioned a mixed economy. It proposed a substantial role for the state in establishing basic and heavy industries, infrastructure, and public services, while allowing private enterprise to operate alongside, which served as a precursor to India's post-independence economic framework.

Explanation

The Indian League was founded in Calcutta in 1875 by Sisir Kumar Ghose, a prominent nationalist journalist and the founder of the Amrita Bazar Patrika newspaper. The primary objective of the Indian League was to stimulate a sense of nationalism and political awareness among the masses, as well as to encourage political education. It acted as one of the significant precursor organizations to the Indian National Congress in fostering nationalist sentiments during the late nineteenth century.

Explanation

The State Reorganisation Commission was constituted by the Central Government of India in December 1953 to recommend the reorganization of state boundaries along linguistic lines.

The commission was headed by retired Supreme Court Chief Justice Fazal Ali (Fajal Ali) as its Chairman. The other two members of this three-member commission were H.N. Kunzru (Pt. Hardyanath Kunjru) and K.M. Panikkar. The commission submitted its report in September 1955, which formed the basis of the States Reorganisation Act, 1956.

Explanation

Balshastri Jambhekar, widely revered as the Father of Marathi Journalism, founded the weekly newspaper Darpan on January 6, 1832, to promote social reform and raise awareness. To further spread knowledge, he started Digdarshan in May 1840, which was the first monthly magazine in Marathi. Digdarshan published informative articles on history, geography, and various branches of science, playing a pivotal role in cultivating a scientific temperament and encouraging modern education among the public.

Explanation

Mahatma Jyotirao Phule was deeply influenced by the ideas of the political theorist and philosopher Thomas Paine. After reading Paine's famous book, The Rights of Man, Phule developed a profound commitment to social justice, individual liberty, and equality. This intellectual influence shaped his lifelong struggle against caste-based discrimination, his advocacy for universal human rights, and his pioneering efforts to educate women and the oppressed classes in India.

Explanation

The Deccan Education Society was established in Pune in 1884 by prominent nationalist leaders and social reformers including Gopal Ganesh Agarkar, Bal Gangadhar Tilak, Vishnushastri Chiplunkar, and Mahadev Ballal Namjoshi. The society was founded with the objective of providing cheap and high-quality western education to Indian youth to foster a spirit of nationalism, self-reliance, and intellectual freedom. It went on to establish iconic institutions such as Fergusson College in Pune to achieve these educational and social reform goals.

Explanation

Dadoba Pandurang Tarkhadkar published the book Dharma Vivechana in 1843 under the pseudonym Ek Jagadvasi Arya. In this treatise, he articulated his reformist philosophy on religion, advocating for a rationalistic, monotheistic belief in one God and the universal brotherhood of humanity while opposing orthodox caste divisions and superstitions. The theological and social tenets outlined in Dharma Vivechana subsequently became the guiding principles for the Manav Dharma Sabha, which he co-founded in Surat in 1844, as well as the Paramahansa Mandali, which he established in Mumbai in 1849.

Explanation

In 1918, Chhatrapati Shahu Maharaj of the princely state of Kolhapur issued a historic decree abolishing the oppressive Mahar Watan system. Under this hereditary system, members of the Mahar community were bound to perform various service duties for the village administration in exchange for small, revenue-free plots of land. By abolishing this practice, he freed them from socio-economic bondage, introduced land reforms enabling them to become direct owners of land, and took a major step toward establishing social equality and dignity for the oppressed classes.

Explanation

Laterite soil is formed in regions of heavy rainfall and high temperatures through the process of intense leaching of silica and organic matter, leaving behind hydrated oxides of iron and aluminium. In Maharashtra, this soil is primarily distributed in the South Konkan coastal region, specifically covering the districts of Ratnagiri and Sindhudurg. These coastal and hilly terrains receive high annual rainfall, which facilitates the laterization process. The heavy presence of iron oxides imparts a characteristic reddish color to this soil, which is extensively used for the cultivation of horticultural crops like mango, cashew, and coconut.

Explanation

Road transport is the dominant mode of transportation in India, carrying approximately 85% of the country's passenger traffic and over 60% of its total freight traffic. It is widely preferred due to its high flexibility, easy accessibility, and ability to provide crucial last-mile and door-to-door connectivity across both urban and remote rural regions of the nation.

Explanation

Most of the rainfall in India is orographic in nature, occurring primarily during the Southwest Monsoon season. When warm, moisture-laden monsoon winds from the Arabian Sea and the Bay of Bengal blow towards the subcontinent, they are obstructed by prominent mountain barriers such as the Western Ghats and the Himalayas. As these winds are forced to ascend the windward slopes of these relief barriers, the air cools adiabatically, leading to condensation, cloud formation, and heavy precipitation on the windward side. Regions on the leeward side of these mountain ranges fall into rain shadow zones and receive significantly less rainfall.

Explanation

Sindhudurg district was officially declared as the first tourism district of India on 30 April 1997. Located in the Konkan region of Maharashtra, the district is blessed with immense natural beauty, boasting a long coastline along the Arabian Sea, pristine beaches, and the lush green Sahyadri mountain range. It is historically significant for its magnificent forts, most notably the Sindhudurg Fort, a massive sea fort built by Chhatrapati Shivaji Maharaj in the 17th century. This unique combination of coastal geography, historical heritage, and vibrant local culture led to its pioneering designation to promote organized regional tourism.

Explanation

Ahmadnagar is the largest district in Maharashtra in terms of geographical area. It covers an area of approximately 17,048 square kilometers, which constitutes about 5.54% of the total geographical area of the state.

Explanation

The Chandrapur Super Thermal Power Station, operated by the Maharashtra State Power Generation Company, is located at Urjanagar near Durgapur in the Chandrapur district. This coal-based power plant has the highest installed capacity in Maharashtra, generating 2920 MW of power, which was later expanded to 3340 MW.

Explanation

The Maharashtra Village Panchayats Act, 1958, Section 10, specifies that a Gram Panchayat shall consist of a minimum of 7 and a maximum of 17 members. The District Collector determines the exact number of members based on the population of the village. Specifically, a village with a population up to 1500 has 7 members; 1501 to 3000 has 9 members; 3001 to 4500 has 11 members; 4501 to 6000 has 13 members; 6001 to 7500 has 15 members; and a population exceeding 7500 has 17 members.

Explanation

Under Section 7 of the Maharashtra Village Panchayats Act, 1958, it was mandatory for a Gram Panchayat to conduct at least six Gram Sabha meetings in every financial year. Failure by the Sarpanch or Upa-Sarpanch to convene these mandatory meetings without sufficient cause within the year resulted in their disqualification from holding office. This requirement of holding six meetings annually was later amended in 2012 to a minimum of four meetings per financial year.

Explanation

The Constitution of India was adopted by the Constituent Assembly on 26th November 1949. This historic date is explicitly mentioned in the Preamble of the Constitution, which states that the people of India, in their Constituent Assembly, adopted, enacted, and gave to themselves the Constitution on this day. Although the Constitution came into full force on 26th January 1950, certain provisions such as those relating to citizenship, elections, provisional parliament, and temporary and transitional measures came into immediate effect on 26th November 1949.

Explanation

In Maharashtra, decentralized planning at the district level was formally initiated with the establishment of the District Planning and Development Councils, translated in Marathi as District Planning and Development Corporation or Board (जिल्हा नियोजन व विकास मंडळ), under the Maharashtra District Planning and Development Council Act, 1974. This institution was formed based on the recommendations of the L. N. Bongirwar Committee (1970) to make the district the primary unit for preparing, formulating, and executing annual and five-year development plans.

Explanation

The District Collector, who also functions as the District Magistrate, is the head of the district administration and holds the ultimate responsibility for maintaining law and order. Under the Police Act of 1861, the district police force operates under the general control and direction of the District Magistrate. The District Collector is vested with extensive magisterial powers under the Code of Criminal Procedure to prevent crime, maintain public peace, control riots, and handle law and order situations within the district.

Explanation

Article 37 of the Constitution of India explicitly states that the Directive Principles of State Policy are not enforceable by any court, making them non-justiciable. While these principles are fundamental to the governance of the country and guide the State in framing policies and making laws, individuals cannot seek legal remedies or approach the judiciary if the State fails to implement them. The framers of the Constitution made them non-justiciable due to the country's limited financial resources and vast socioeconomic diversity at the time of independence, allowing the government the flexibility to implement them gradually as the nation progressed.

Explanation

The Vasantrao Naik Committee was appointed by the Government of Maharashtra in June 1960 to study and recommend a suitable model for implementing the Panchayati Raj system in the state. Based on the comprehensive recommendations of this committee, which advocated for a strong, decentralized three-tier local self-governing structure with the Zilla Parishad at its core, the state legislature passed the Maharashtra Zilla Parishads and Panchayat Samitis Act, 1961. This landmark legislation paved the way for the establishment of functional democratic decentralization in Maharashtra, officially coming into effect on 1 May 1962.

Explanation

Our public life is regulated by the Constitution and laws because they establish the supreme legal framework and code of conduct for the country. The Constitution provides the foundational principles, structures, and limits of governance, while the statutory laws enacted under it guide, standardize, and maintain order in the daily interactions, rights, duties, and transactions of citizens and public institutions.

Explanation

The Block Development Officer serves as the administrative head and executive officer of the Panchayat Samiti at the block level. As part of their official administrative and financial duties, the Block Development Officer is responsible for preparing the annual budget estimates of income and expenditure for the Panchayat Samiti and submitting it to the Samiti for consideration and approval.

Explanation

The 73rd Constitutional Amendment Act of 1992 inserted Part IX into the Constitution of India, which is titled The Panchayats and consists of provisions from Articles 243 to 243O. It also added the Eleventh Schedule, which details 29 functional items within the purview of the Panchayats, thereby establishing a three-tier system of Panchayati Raj across the country and giving constitutional status to these local self-government institutions.

Explanation

Under the Maharashtra Village Panchayats Act, 1958, the Gramsevak is appointed by the Chief Executive Officer of the Zilla Parishad to act as the ex-officio Secretary of the Gram Panchayat. The Gramsevak handles the administrative, financial, and developmental duties of the panchayat, maintains official records and registers, and serves as the primary administrative link between the village panchayat and the higher tiers of rural local government.

Explanation

An analogy is a cognitive process or comparison that identifies shared characteristics or resemblances between two different things, concepts, or factors. By highlighting these similarities, an analogy helps in understanding a less familiar concept by comparing it to a more familiar one. Thus, identifying or taking resemblances between two factors is the core defining feature of an analogy.

Explanation

Classification is the fundamental first step in the development of any scientific discipline. Before formulating precise definitions, performing systematic divisions, or constructing testable hypotheses, science relies on organizing and grouping raw observational data, facts, and phenomena based on shared characteristics, similarities, or relationships. This categorization process provides the structured framework necessary for higher-level scientific inquiry and theoretical advancements.

Explanation

Hypothermia is a medical emergency that occurs when the body loses heat faster than it can produce it, causing the core body temperature to fall below 35°C (95°F). Normal human body temperature is typically around 37°C (98.6°F), and a drop below 35°C disrupts normal metabolism and physiological functions, leading to symptoms ranging from shivering and confusion to heart and respiratory failure.

Explanation

Malnutrition arises from a variety of socio-economic, environmental, and behavioral factors that interfere with proper nutrient intake and absorption.

Poverty and ignorance are primary socio-economic contributors. Poverty directly limits financial capacity to purchase diverse and nutrient-rich foods, while ignorance or a lack of nutritional awareness often leads to poor dietary choices, even when resources are available.

Behavioral habits like fast eating and improper timing of eating disrupt the normal digestive process. Eating too quickly reduces the efficiency of chewing and can impair the absorption of vital nutrients in the digestive tract. Irregular timing of meals further disturbs metabolic cycles, hindering optimal nutrient assimilation.

Famine represents an extreme environmental factor where acute, widespread food scarcity directly leads to severe nutritional deficiencies and starvation across populations.

Since economic limitations, poor eating habits, and extreme environmental crises all lead to inadequate nutrition, all three factors are recognized causes of malnutrition.

Explanation

The SI unit of power is the watt, represented by the symbol W. Power is defined as the rate at which work is done or energy is transferred. Mathematically, power equals work done divided by time taken (P = W/t). Since the SI unit of work is the joule and the SI unit of time is the second, one watt is equal to one joule per second (1 W = 1 J/s). The unit is named in honor of the Scottish inventor James Watt for his contributions to the development of the steam engine.

Explanation

Plaster of Paris, chemically known as calcium sulfate hemihydrate with the formula CaSO₄·½H₂O, is prepared by heating gypsum to a temperature of about 373 K (100 °C). Gypsum is a naturally occurring mineral composed of calcium sulfate dihydrate, represented by the chemical formula CaSO₄·2H₂O. When heated to 373 K, gypsum loses three-fourths of its water of crystallization, yielding Plaster of Paris. If gypsum is heated above this temperature, it loses all its water molecules to form anhydrous calcium sulfate, which is commonly referred to as dead burnt plaster.

Explanation

Milk is a highly rich and bioavailable dietary source of calcium, containing approximately 120 mg of calcium per 100 g of fluid. The calcium in milk is exceptionally well-absorbed by the human body because of the natural presence of lactose and vitamin D, which facilitate efficient calcium absorption in the gut.

Explanation

Onions store their reserve food material in the form of carbohydrates, which primarily consist of soluble sugars. The onion bulb is a modified underground shoot made up of a highly reduced disc-like stem surrounded by concentric, fleshy scale leaves. During active growth, the plant performs photosynthesis in its green aerial leaves to produce food, which is then translocated to these fleshy scale leaves. Instead of storing this energy as starch like many other tubers, onions store it as simple carbohydrates and sugars, including glucose, fructose, sucrose, and complex fructose polymers called fructans. These stored carbohydrates provide the necessary energy for the plant to survive dormancy and sprout new growth in the next season.

Explanation

SONAR (Sound Navigation and Ranging) operates on the principle of reflection of sound waves, commonly known as an echo. The transmitter of a sonar device emits ultrasonic sound pulses that travel through water until they strike an obstacle or the seabed. Upon impact, these sound waves bounce back and are received by a detector as an echo. By measuring the time interval between the transmission of the pulse and the reception of its echo, along with the speed of sound in water, the exact distance and direction of the underwater object are calculated.

Explanation

Surface tension is the cohesive force among liquid molecules at the interface, which causes the surface layer of a liquid to behave like a stretched elastic membrane. Molecules in the bulk of the liquid experience attractive forces from all directions, resulting in a net force of zero. However, molecules at the surface experience a net inward attraction toward the interior of the liquid because there are no liquid molecules above them. This net inward pull acts to minimize the surface energy of the liquid, causing the surface area to contract to its minimum possible value. Since a sphere has the smallest surface area for a given volume, liquid drops naturally assume a spherical shape.

Explanation

Modernisation is a comprehensive, multidimensional process of social change whereby traditional, agrarian, and rural societies transform into modern, industrial, and secular societies. It encompasses the transformation of social values, norms, structures, and institutions as a whole. Because it alters the entire social framework and influences collective human behavior, relationships, and lifestyles, the process of modernisation is fundamentally connected with society.

Explanation

All the listed industries are major contributors to environmental degradation. Cement factories release massive quantities of dust, particulate matter, carbon dioxide, and sulfur dioxide into the atmosphere. Sugar factories produce highly polluting organic effluents with high biochemical oxygen demand (BOD) alongside air pollutants from boiler emissions. Chemical factories are notorious for discharging toxic liquid wastes, hazardous chemical residues, and air pollutants into the ecosystem. Because each of these manufacturing sectors is classified as a highly polluting industry, none of them can be considered non-polluting.

Explanation

Radiation from radioisotopes is widely utilized in industrial applications for non-destructive testing and wear analysis. In industrial radiography, gamma-emitting isotopes such as Cobalt-60 or Iridium-192 are used to inspect metal mouldings, castings, and welds. The high-energy radiation penetrates the metal, and any internal cracks, voids, or holes appear as dark spots on a radiographic film placed behind the object because fewer metal atoms are present to block the radiation. For studying the wear of machinery, a small amount of a radioactive isotope tracer like Iron-59 is incorporated into the moving parts such as piston rings. As the machine operates, the microscopic wear particles containing the isotope accumulate in the lubricating oil, allowing researchers to measure the exact rate of wear by monitoring the radioactivity levels in the oil without dismantling the machine.

Explanation

Calcium is the most abundant metal in the human body, accounting for about 1.5% to 2% of total body mass. The vast majority of this calcium, approximately 99%, is stored in the bones and teeth in the form of calcium phosphate compounds, providing vital structural strength and support. The remaining small percentage is distributed in blood, extracellular fluid, and soft tissues, where it is crucial for essential physiological functions such as muscle contraction, blood clotting, nerve impulse transmission, and cellular signaling.

Explanation

Gobar gas, commonly known as biogas, is produced through the anaerobic digestion of animal waste, primarily cow dung, by anaerobic microorganisms in an oxygen-free environment. The main and most abundant constituent of gobar gas is methane (CH₄), which typically accounts for 50% to 75% of its total volume. Methane is a highly efficient, clean-burning hydrocarbon gas that serves as an excellent fuel source for heating, cooking, and generating electricity.

Explanation

Nanotechnology is defined as the understanding, manipulation, and control of matter at the nanoscale, which generally encompasses the dimension range of 1 to 100 nanometers. At this scale, quantum mechanical effects become dominant, and materials exhibit unique physical, chemical, and biological properties that differ significantly from those of their bulk counterparts. This specific molecular range allows for the design and engineering of novel materials and devices with enhanced strength, chemical reactivity, optical properties, or electrical conductivity.

Explanation

Solar energy is generated in the core of the Sun through the process of nuclear fusion. Under extremely high temperatures and pressures, four hydrogen nuclei (protons) fuse together to form a single helium nucleus. During this nuclear transmutation, a small amount of mass is lost and converted into a massive amount of energy according to the mass-energy equivalence equation E = mc². This energy is released in the form of electromagnetic radiation, which travels through space and reaches the Earth as solar energy.

Explanation

A hygrometer is an instrument specifically designed to measure the moisture content or relative humidity of the atmosphere. It operates based on changes in the physical, chemical, or electrical properties of substances as they absorb moisture. For instance, classic hair hygrometers utilize the principle that organic materials like human hair expand and contract in response to relative humidity, while modern digital hygrometers measure changes in the electrical capacitance or resistance of a thin-film polymer to calculate the precise percentage of water vapor present in the air.

Explanation

Fibrous, porous, and soft materials are highly efficient absorbers of sound waves. In large, enclosed spaces like auditoriums, sound waves continuously bounce off hard, reflective surfaces such as concrete, glass, or polished wood. This repeated reflection of sound waves results in reverberation and the creation of distracting echoes, which make speech and music unclear and difficult to comprehend. By covering the walls and ceilings with fibrous materials, such as compressed fiberboards or heavy draperies, the energy of the incident sound waves is absorbed and dissipated as heat within the porous structure rather than being reflected back into the room. This sound absorption prevents the occurrence of multiple reflections and echoes, thereby improving the overall acoustic quality of the hall.

Explanation

Diamond is the hardest known natural material. It is an allotrope of carbon in which the carbon atoms are arranged in a highly symmetric, face-centered cubic crystal structure. Each carbon atom is covalently bonded to four other carbon atoms in a tetrahedral geometry. These strong covalent bonds are uniform throughout the three-dimensional lattice, making the entire structure incredibly rigid and resistant to scratching or deformation. On the Mohs hardness scale, diamond is defined as having the maximum hardness value of 10.

Explanation

Natural science is a branch of science concerned with the description, understanding, and prediction of natural phenomena, based on empirical evidence from observation and experimentation. Chemistry is classified as a physical science, which is a major subdiscipline of natural science. It focuses on the systematic study of matter, its composition, structure, properties, and the changes it undergoes during chemical reactions.

Explanation

Chloroquine is an established antimalarial medication widely used for the suppression, prevention, and treatment of malaria. It functions by entering the acidic food vacuoles of the malaria parasite (Plasmodium species) and preventing the biocrystallization of toxic free heme into non-toxic hemozoin. The resulting accumulation of free heme is highly toxic to the parasite, leading to its death. For individuals requiring chemoprophylaxis in malaria-endemic regions, chloroquine acts as a clinical suppressive drug. Splitting the standard prophylaxis regimen into low doses taken twice a week helps maintain stable, protective therapeutic blood concentration levels while significantly reducing common adverse side effects such as nausea, gastrointestinal discomfort, and pruritus.

Explanation

Kidney stones, medically known as renal calculi, are solid deposits of minerals and acid salts that crystallize inside the kidneys. The vast majority of these stones, accounting for approximately 70% to 80% of all cases, are composed of calcium oxalate. They form when urine contains high concentrations of calcium and oxalate, which bind together to form crystals that gradually aggregate into stones.

Explanation

The space shuttle Discovery mission STS-116, launched on December 10, 2006 (UTC), was dedicated to the construction, assembly, and repair of the International Space Station (ISS). Its primary objectives included the installation of the P5 spacer truss segment, a major electrical rewiring of the station to support its final configuration, and the rotation of Expedition 14 crew members, which brought Indian-origin American astronaut Sunita Williams to the station.

Explanation

Kinetic energy is the energy possessed by an object due to its motion. When a sportsman is running, they are in a state of motion and have velocity. The kinetic energy of any moving body is given by the formula KE = ½mv², where m is the mass of the sportsman and v is their running velocity. Since the sportsman has both mass and velocity, they possess kinetic energy.

Explanation

The Master Control Facility of the Indian Space Research Organisation is located at Hassan in Karnataka. Established in 1982, this premier facility is responsible for the post-launch operations, orbit maneuvers, station-keeping, and overall health monitoring of India's geostationary and geosynchronous satellites, including the INSAT and GSAT series.

Explanation

Metals possess a crystalline lattice structure where the outer valence electrons are loosely bound to their atomic nuclei. These electrons easily detach to form a highly mobile sea of delocalized free electrons that can move throughout the metal. When an electric potential difference is applied across the metal, these free electrons drift toward the positive terminal. This rapid movement of charge carriers constitutes an electric current, allowing metals to conduct electricity with very low resistance.

Explanation

Chikungunya is a viral disease transmitted to humans by the bite of infected female mosquitoes of the genus Aedes, primarily Aedes aegypti. This mosquito species is active during the daytime, particularly during the early morning and late afternoon, and is also responsible for transmitting other viral infections such as dengue and yellow fever.

Explanation

Mosquito fish (Gambusia affinis) and Guppy or Gappi fish (Poecilia reticulata) are highly effective biological control agents against mosquito-borne diseases. These small, hardy, and prolific freshwater fish are classified as larvivorous because they feed voraciously on the aquatic larval and pupal stages of mosquitoes, preventing them from developing into adult disease vectors. They inhabit the upper layers of water bodies where mosquito larvae breed, making them highly efficient predators for controlling mosquito populations in ornamental ponds, drains, wells, and other stagnant water pools.

Explanation

Marble is a metamorphic rock composed primarily of recrystallized carbonate minerals, most commonly calcite, which is a crystalline form of calcium carbonate (CaCO₃). It forms when sedimentary carbonate rocks, such as limestone, are subjected to high temperatures and pressures beneath the Earth's crust, making marble a prominent and highly pure variety of calcium carbonate.

Explanation

Creeping inflation, characterized by a slow and mild rise in price levels typically under 3% annually, is considered essential for the economic development of a country. A predictable and gentle rise in prices acts as an incentive for producers, as it maintains profit margins and encourages them to increase production and make long-term capital investments. This investment leads to job creation and economic expansion. Additionally, mild inflation prevents the economy from falling into deflation, encouraging consumers to purchase goods and services now rather than postponing consumption, which sustains aggregate demand and keeps economic growth steady.

Explanation

The Dual Price Policy in India was first introduced in 1967-68 for sugar. Under this policy, the government divided sugar production into two parts: levy sugar and free-sale sugar. Sugar mills were required to sell a specified percentage of their total production (known as levy sugar) to the government at a controlled, below-market price for distribution to low-income consumers through the Public Distribution System. The remaining portion of the sugar (known as free-sale sugar) could be sold by the mills in the open market at prevailing market-determined prices to help them recover their production costs and remain financially viable.

Explanation

Developmental expenditure of the Central Government refers to the financial outlay directed towards the socio-economic development of the nation, which helps in increasing productive capacity and improving social welfare. It primarily includes expenditure on social and community services (such as education, public health, and social security), economic services (such as agriculture, industry, power, transport, and communication), and grants-in-aid to states and union territories for developmental purposes.

On the other hand, expenditure on general administrative services, defence, external affairs, pensions, and interest payments is classified as non-developmental expenditure as it does not directly lead to asset creation or immediate economic growth. Therefore, (a), (b), and (c) are included in developmental expenditure.

Explanation

Under the Annual Supplement to the Foreign Trade Policy (FTP) 2004-09, announced for the financial year 2005-06, the limit for the duty-free import of commercial samples for the Gems and Jewellery sector was enhanced from ₹1 lakh to ₹3 lakhs per annum. This measure was introduced to provide a boost to the export of gems and jewellery by making high-quality samples more accessible to Indian exporters.

Explanation

In 2006, the public sector banking system in India comprised 28 banks. These consisted of the State Bank of India, seven associate banks of the State Bank of India, nineteen nationalised banks, and IDBI Bank Limited. IDBI Bank Limited was categorized under the other public sector bank group by the Reserve Bank of India in 2005.

The total is computed as 1 + 7 + 19 + 1 = 28.

Explanation

The Janata Party government assumed power in 1977 and terminated the Fifth Five-Year Plan one year ahead of its schedule in 1978. In its place, they introduced their own Sixth Five-Year Plan for the period 1978-83. This plan implemented the Rolling Plan concept, which was formulated under the guidance of D.T. Lakdawala, allowing for annual assessment and flexible target adjustments rather than rigid five-year projections.

Explanation

The Raja Chelliah Committee was appointed by the Government of India in August 1991 as the Tax Reforms Committee. Its primary mandate was to examine the existing system of direct and indirect taxes in India and suggest comprehensive measures to make it simple, rational, and more revenue-elastic. The committee submitted three reports between 1991 and 1993, which proposed major changes such as the reduction and rationalization of personal income tax and corporate tax rates, simplification of customs and excise duties, and the introduction of a value-added tax system. As a result, it is associated entirely with fiscal and tax reforms rather than banking reforms.

Explanation

The Union Budget of 1991–92, presented amid India's balance-of-payments crisis, set a target of reducing the gross fiscal deficit of the Central Government from around 8.4% of GDP in 1990–91 to 6.5% of GDP. This was a central plank of the fiscal consolidation and stabilisation measures undertaken alongside the broader economic liberalisation reforms initiated that year under Finance Minister Dr. Manmohan Singh.

Explanation

Federal Bank Limited is a major Indian commercial bank operating in the private sector. Headquartered in Aluva, Kochi, Kerala, the bank was established in 1931 as Travancore Federal Bank and renamed Federal Bank in 1947. Since its inception, it has functioned as a private sector entity and was not included in the banking nationalisation drives undertaken by the Government of India in 1969 and 1980.

Explanation

Fluctuation in output is a supply-side factor rather than a demand-pull factor. When the production or supply of essential goods and services fluctuates or decreases, it leads to a shortage in the market, which directly pushes prices upward. This type of price rise is driven by supply shocks and bottlenecks in the production chain, rather than an expansion of aggregate demand or an increase in consumer purchasing power.

Explanation

At the launch of the First Five-Year Plan in 1951, the newly independent nation of India was grappling with several severe economic and social crises. The partition of British India in 1947 had resulted in a massive influx of millions of refugees who needed urgent resettlement and rehabilitation. Partition also disrupted India's agricultural output, as highly fertile and irrigated agricultural lands of West Punjab and East Bengal went to Pakistan, triggering acute food shortages. Furthermore, the combined legacy of World War II and partition created severe supply bottlenecks, leading to hyperinflation and a rise in the cost of essential commodities. Consequently, the First Five-Year Plan focused heavily on agriculture, irrigation, and price stabilization to simultaneously resolve the crises of food shortages, inflation, and refugee rehabilitation.

Explanation

The Tenth Five Year Plan of India was implemented for the period spanning from 1 April 2002 to 31 March 2007. Launched under the leadership of Prime Minister Atal Bihari Vajpayee and later continued under Prime Minister Manmohan Singh, this plan set an ambitious target to achieve an 8% annual GDP growth rate. The key focus areas of the Tenth Plan included doubling the per capita income of India within ten years, reducing the poverty ratio by 5 percentage points by 2007, providing high-quality employment opportunities, and improving general social indicators such as literacy and gender equity.

Explanation

During the First Five Year Plan (1951–1956), India witnessed a unique phase of deflation where the general price level declined by approximately 13%. This was primarily driven by exceptional agricultural growth and record foodgrain production resulting from highly favorable monsoon seasons, which significantly eased the prevailing food shortages and stabilized the post-independence economy.

Explanation

The Prime Minister of India serves as the ex-officio Chairman of the Planning Commission. Established in March 1950 by a Resolution of the Government of India, the Planning Commission was a non-constitutional and advisory body designed to formulate India's Five-Year Plans for social and economic development. The position of Chairman was vested in the Prime Minister to ensure that the country's development planning aligned closely with national executive leadership and policy direction.

Explanation

In the Union Budget of India for the fiscal year 2005–06, the basic personal income tax exemption limit for general individual taxpayers was increased to Rs. 1 lakh from the earlier limit of Rs. 50,000. The same budget also raised the exemption limit to Rs. 1.35 lakh for women and Rs. 1.85 lakh for senior citizens.

Explanation

The concept of Zero-Based Budgeting was pioneered in India during the 1980s. Maharashtra became the first state in the country to adopt and implement this budgeting technique in 1986 under its state budget planning. This system requires every department to justify all of its expenditures from scratch (a zero base) for each new financial year, rather than simply making incremental changes to the previous year's budget.

Explanation

Gross Fiscal Deficit represents the total borrowing requirement of the government. It is defined as the excess of total government expenditure, which includes both revenue and capital expenditures along with net lending, over non-debt receipts, which consist of current revenue and grants.

The relationship is expressed as: Gross Fiscal Deficit = (Government Expenditure + Net Lending) - (Current Revenue + Grants)

This makes both statement (a) and statement (b) correct as they represent the two components whose difference determines the gross fiscal deficit.

Explanation

The Foreign Trade Policy 2004-09 was announced on August 31, 2004, by Mr. Kamal Nath, who served as the Union Minister of Commerce and Industry. Replacing the earlier Export-Import (EXIM) Policy, this policy adopted an integrated approach to foreign trade, focusing on doubling India's share of global merchandise trade and generating employment.

Explanation

Importing capital goods, such as machinery and advanced industrial equipment, directly enhances a nation's productive capacity and capital formation. Unlike goods destined for immediate consumption, capital goods are utilized to produce other goods and services, which boosts labor productivity and facilitates technological advancement. By introducing efficient machinery and new technologies into the domestic economy, these imports help domestic industries scale up operations, lower per-unit production costs, and modernise manufacturing processes. This strengthens the country's industrial foundation and drives long-term, sustainable GDP growth.

Explanation

The total outlay of the Eighth Five Year Plan (1992-1997) was estimated at ₹ 8,71,000 crores. This plan period marked a major transition for the Indian economy toward a market-oriented system following the 1991 economic reforms. Within this total plan outlay, the total proposed investment was ₹ 7,98,000 crores, and the public sector outlay was allocated at ₹ 4,34,100 crores.

Explanation

Devaluation of a currency reduces its value relative to foreign currencies. When the Indian rupee was devalued in June 1966, the foreign currency price of Indian export goods decreased, making them cheaper and more competitive in the international market. This gave Indian export goods a significant price advantage, helping to boost export volumes by attracting foreign buyers with lower prices.

Explanation

In July 1976, the Government of India constituted the Indirect Taxation Enquiry Committee under the chairmanship of Lakshmi Kant Jha (L.K. Jha), a distinguished civil servant and former Governor of the Reserve Bank of India. The committee was tasked with reviewing the existing structure of indirect taxes, examining their impact on prices and resource allocation, and recommending measures to simplify and modernize the system. A major recommendation of the Jha Committee was the introduction of a value-added tax at the manufacturing level (MANVAT) to mitigate cascading tax effects, which eventually paved the way for the implementation of the Modified Value Added Tax (MODVAT) in 1986.

Explanation

India's direction of foreign trade has undergone structural shifts since independence and especially after the economic reforms of 1991. Historically, India had a very high concentration of trade with traditional developed markets, particularly the member nations of the Organisation for Economic Co-operation and Development (OECD). Over the decades, India successfully diversified its trade relations toward developing regions and other emerging markets. As a result, the share of OECD countries in both India's exports and imports has steadily declined, reducing India's excessive dependency on these traditional developed economies.

Explanation

The "Garibi Hatao" (Eradicate Poverty) slogan was formally integrated as a major objective in the Fifth Five-Year Plan (1974–1978). Although Prime Minister Indira Gandhi introduced the slogan during her general election campaign in 1971, the institutional focus on poverty alleviation, minimum needs, and employment generation was officially structured and implemented during the Fifth Five-Year Plan.

Explanation

The Wholesale Price Index (WPI) in India represents the price of a representative basket of wholesale goods. To calculate this average index, the items are broadly classified into three major commodity groups: primary articles, fuel and power (fuel groups), and manufactured products. All three categories are essential components with their respective assigned weights, and their combined price movements are used to work out the average wholesale inflation rate in the country.

Explanation

In 1961, the Government of India appointed the Import and Export Policy Committee, which submitted its report in 1962. This committee was chaired by Sir Arcot Ramaswami Mudaliar. The primary objective of the committee was to review India's trade policy, evaluate the import control systems, and suggest effective strategies for export promotion and coordinating import licensing. The recommendations of the Mudaliar Committee laid the groundwork for integrating import-export regulations with industrial development priorities.

Explanation

In 2006, Punjab National Bank (PNB) launched 'PNB Arogya Shree', a health insurance/mediclaim scheme in partnership with Reliance General Insurance Company. The scheme was designed for PNB account holders and their families, offering cashless hospitalization and group health cover benefits, and was one of the earliest bank-linked health insurance products in India at the time.

Explanation

During the fiscal year 1991-92, India experienced its highest rate of inflation among the given periods, reaching double digits with the Wholesale Price Index averaging around 13.7% and the Consumer Price Index averaging approximately 13.87%. This surge in inflation was primarily driven by the severe balance of payments crisis of 1990-91 and the subsequent sharp two-step devaluation of the Indian Rupee in July 1991, which significantly escalated import costs and fueled domestic inflationary expectations.

Explanation

The mutual fund industry in India was pioneered by the Unit Trust of India, which was established in 1963 by an Act of Parliament. Created as a joint initiative of the Government of India and the Reserve Bank of India, it aimed to encourage small savers to invest in the capital market. Unit Trust of India introduced the country's first mutual fund scheme, Unit Scheme 1964, in 1964, marking the official launch of the mutual fund industry in India.

Explanation

Regional Rural Banks are financial institutions established under the Regional Rural Banks Act of 1976 to ensure sufficient institutional credit for agriculture and other rural sectors. The share capital of these banks is subscribed by the Central Government, the sponsor bank, and the respective State Government in a predetermined ratio. The concerned State Government contributes exactly 15% of the authorized share capital of a Regional Rural Bank, while the Central Government contributes 50% and the designated sponsor bank contributes the remaining 35%.

Explanation

According to the Agricultural Census of India, operational holdings are categorized based on size, where marginal holdings are defined as agricultural land holdings of less than 1.00 hectare.

During the Agricultural Census of 1990-91, marginal land holders constituted 61.6% of the total operational land holdings in the country. This value is rounded to approximately 62%. This marked a notable increase from the 1970-71 agricultural census, during which marginal land holdings accounted for approximately 51% of the total operational holdings.

Explanation

NABARD (National Bank for Agriculture and Rural Development) was established on July 12, 1982, under the NABARD Act of 1981, based on the recommendations of the B. Sivaraman Committee. It functions as the apex development bank in India, specifically mandated to facilitate credit flow and formulate policies for the promotion and development of agriculture, small-scale industries, cottage and village industries, handicrafts, and other rural crafts. It plays a pivotal role in rural prosperity by coordinating the rural financing activities of all institutions engaged in developmental work and ensuring effective credit delivery in rural areas.

Explanation

The estimated potential of the yearly marine fish catch for Maharashtra is 6.3 lakh tonnes (0.63 million tonnes), as per the assessment by the state's Department of Fisheries and the Central Marine Fisheries Research Institute (CMFRI). Maharashtra has a coastline of 720 km spanning seven maritime districts, with a continental shelf area of about 1.12 lakh square kilometers. This estimated potential represents the sustainable limits of marine resources that can be harvested from the state's territorial waters and continental shelf area without harming the marine ecosystem.

Explanation

In 2005-06 the Government of Maharashtra launched MAHA-PIC (Maharashtra Agriculture Productivity Improvement Campaign) to boost crop productivity across the state through integrated interventions such as improved seed distribution, soil health measures, and farmer training. Unlike the generic High Yielding Variety Programme or land development activities, MAHA-PIC was the specific, named state-level campaign introduced that year to raise agricultural output and farmer incomes.

Explanation

The National Research Centre on Coldwater Fisheries was established in September 1987 under the aegis of the Indian Council of Agricultural Research. It is located at Bhimtal in the Nainital district of Uttarakhand. The institute is dedicated to conducting research on the conservation, management, and sustainable development of coldwater fishery resources in the upland regions of India. It was later upgraded to the Directorate of Coldwater Fisheries Research during the eleventh five-year plan.

Explanation

The bitterness in groundnut kernels is due to aflatoxin, which is a toxic secondary metabolite produced by fungi, primarily Aspergillus flavus and Aspergillus parasiticus. This fungal infestation typically occurs under conditions of high moisture and improper drying or storage of the groundnut pods, leading to the development of a bitter taste in the contaminated kernels.

Explanation

The pan evaporometer measures the rate of evaporation from an open water surface, which integrates the combined meteorological influences of solar radiation, wind speed, ambient temperature, and relative humidity. Since these same atmospheric factors drive transpiration from plants, pan evaporation rates are highly correlated with potential and reference evapotranspiration, allowing researchers and agriculturists to estimate plant water loss over time.

Explanation

The Maharashtra Water and Irrigation Commission, also known as the Chitale Commission, estimated the ultimate irrigation potential of Maharashtra to be 126 lakh hectares (or 12.6 million hectares) in its 1999 report. This total potential is divided into 85 lakh hectares from surface water sources and 41 lakh hectares from groundwater resources. Given that the state has a total cultivable area of approximately 225 lakh hectares, this ultimate potential indicates that about 56% of Maharashtra's cultivable land can be irrigated.

Explanation

The tea mosquito bug (Helopeltis antonii) is the most devastating and major sucking pest of cashew plantations in Maharashtra. Both nymphs and adults cause severe damage by piercing and sucking the sap from tender shoots, inflorescences, developing nuts, and apples. This feeding leads to reddish-brown necrotic spots, causing shoot drying and inflorescence blight. Infestations can result in significant economic yield losses ranging from 30% to 50%, and up to 100% in severe cases.

Explanation

Norin-10 is a semi-dwarf wheat variety originating from Japan that contains the major dwarfing genes Rht1 and Rht2. These genes reduce the height of the wheat plants to about 60 to 110 cm, preventing lodging when heavily fertilized and ensuring the efficient allocation of nutrients to grain development rather than vegetative growth. This dwarfing source was extensively utilized by Norman Borlaug at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico to breed the high-yielding, fertilizer-responsive semi-dwarf wheat varieties that triggered the Green Revolution in the 1960s.

Explanation

The Vasantrao Naik Sheti Swavalamban Mission (VNSSM) was established by the Government of Maharashtra in December 2005 to address the severe farm distress and rising suicide rates among farmers in the Vidarbha region. Headquartered in Amravati, the mission's primary focus is on the six most suicide-prone cotton-growing districts of Maharashtra: Amravati, Akola, Yavatmal, Washim, Buldhana, and Wardha. It was constituted as part of a special rehabilitation package to streamline the delivery of crop credit, promote loan restructuring, facilitate crop insurance, provide support for alternative livelihoods, and coordinate welfare schemes for farming households in distress.

Explanation

Golden rice is a genetically engineered variety of rice developed to biosynthesize beta-carotene, a precursor of vitamin A, in the edible endosperm of the grain. The presence of beta-carotene gives the rice its distinctive golden-yellow color and serves as a dietary source to help combat vitamin A deficiency in regions where rice is the primary staple food.

Explanation

The recorded forest area of Maharashtra is 61,939 square kilometers, which represents approximately 20.13% of the state's total geographical area of 307,713 square kilometers. This recorded forest area consists of 79.46% reserved forests, 13.23% protected forests, and 7.31% unclassed forests.

Explanation

Mulching is the practice of covering the soil surface around plants with organic materials, such as straw, grass clippings, and wood chips, or synthetic materials like plastic films. This layer acts as a physical barrier that minimizes the evaporation of moisture from the soil surface directly into the atmosphere. By conserving soil moisture and reducing the overall volume of water required for irrigation, mulching directly enhances water conservation and improves the water use efficiency of the crop.

Explanation

The pineapple, scientifically known as Ananas comosus, originated in the tropical regions of South America, specifically in the area encompassing southern Brazil and Paraguay along the Paraná-Paraguay river basin. This region is home to the wild relatives of the crop, confirming it as the primary botanical and evolutionary center of origin. Indigenous populations domesticated and cultivated the fruit long before European explorers introduced it to other tropical regions of the world during the sixteenth century.

Explanation

Fertigation is the process of applying water-soluble fertilizers directly to crops through an irrigation system, particularly drip irrigation. This technique ensures that essential nutrients are delivered precisely to the active root zone of the plants, optimizing nutrient uptake and significantly reducing wastage through leaching or volatilization. It provides farmers with precise control over the concentration and timing of nutrient delivery, leading to improved crop yield and resource efficiency.

Explanation

Yavatmal district has historically held the largest area under cotton cultivation in Maharashtra, particularly within the Vidarbha region. The agro-climatic conditions of the district, featuring fertile black cotton soil and a moderate, semi-arid climate, are highly conducive to growing rain-fed cotton. Yavatmal contributes a massive share to the state's overall cotton acreage and remains a central hub for cotton-based industries, ginning factories, and trade in Maharashtra.

Explanation

An average whole egg, weighing approximately 50 to 58 grams, provides around 70 to 80 Calories (kcal) of energy. Of this energy, the nutrient-dense egg yolk contributes approximately 60 Calories, while the egg white (albumen) contributes about 15 to 20 Calories. Therefore, 80 Calories is the standard average energy value received from one egg.

Explanation

Timber is classified as a major forest produce in Maharashtra and is the largest contributor to the state's forest-based revenue. The Forest Development Corporation of Maharashtra (FDCM) and the State Forest Department manage vast teak plantations that yield high-value, high-quality timber. While minor forest products like bamboo, tendu leaves, and grass contribute to local livelihoods, their total financial return to the state treasury is significantly lower compared to the commercial timber harvests.

Explanation

During kharif 2006–2007, soyabean recorded the highest production among Maharashtra's kharif crops, reaching roughly 28-29 lakh tonnes. This surge reflected the rapid expansion of soyabean cultivation across Vidarbha and Marathwada, where it displaced traditional crops like jowar and cotton in many areas due to better returns and processing demand. Rice, though significant in the Konkan and eastern Vidarbha belt, and jowar, grown widely across the state, both trailed soyabean in total kharif production that year, making soyabean the dominant kharif crop of the season.

Explanation

The H5N1 strain of avian influenza, commonly known as bird flu, is a highly pathogenic subtype of the Influenza A virus. It is considered the most dangerous causative strain of avian flu due to its high mortality rate in birds and its capability to cause severe, often fatal respiratory illness in humans. During the outbreaks leading up to 2006, H5N1 caused significant agricultural damage and raised global pandemic concerns because of its high fatality rate in clinically diagnosed human cases, typically contracted through direct contact with infected poultry.

Explanation

Established in 1946, this center is dedicated to the scientific breeding, genetic improvement, and conservation of the indigenous Dangi cattle breed, which is well-adapted to the high rainfall and hilly terrain of the Western Ghats.

Explanation

Carotene is a fat-soluble carotenoid pigment naturally abundant in the fresh grass, green fodder, and plants consumed by cows. When cows digest this vegetation, the pigment is absorbed and transferred into the fat globules of their milk. Because carotene is dissolved in the milk fat, it imparts a characteristic light yellowish color to cow's milk. In addition to giving the milk its golden hue, carotene serves as a vital antioxidant and a precursor to vitamin A in the human diet.

Explanation

During 2004-05 in Maharashtra, the Social Forestry Department undertook various afforestation and plantation activities under social forestry schemes on non-forest lands, community lands, and roadside areas. According to the state's forestry and economic records, the department successfully completed tree plantation on an area of 4,850 hectares, which is equivalent to 4.85 thousand hectares.

Explanation

Gypsum, chemically known as calcium sulfate dihydrate (CaSO₄·2H₂O), is widely used to reclaim alkaline soils which are characterized by high levels of exchangeable sodium ions (Na⁺) and a high pH. When gypsum is applied to the soil, it dissolves to release calcium ions (Ca²⁺). These calcium ions displace the exchangeable sodium ions adsorbed on the clay complex. The displaced sodium reacts with the sulfate from gypsum to form soluble sodium sulfate (Na₂SO₄), which is then easily leached down below the root zone through irrigation or rainwater. This exchange process improves soil aggregation, enhances water infiltration, reduces soil crusting, and lowers the soil pH, making the land suitable for agricultural cultivation.

Explanation

Drip irrigation is highly effective when utilizing irrigation water with high salt content because it applies water slowly and frequently directly to the root zone of the plant. This continuous application of water maintains a consistently high soil moisture level, which dilutes the concentration of dissolved salts and minimizes osmotic stress on the plant roots. Furthermore, the outward movement of water from the dripper continuously leaches and pushes the accumulated salts to the periphery of the wetted soil bulb, keeping the active root zone relatively salt-free and conducive to plant growth.

Explanation

Virat is an extra-bold seeded Kabuli variety of chickpea (Cicer arietinum). It is wilt-resistant, semi-erect, and produces large, attractive seeds that fetch a premium market price.

Explanation

According to the 1997 Livestock Census of Maharashtra, the total cattle population was approximately 18.07 million, while the buffalo population was about 6.07 million. The ratio of cattle to buffaloes is:

18.07 million ÷ 6.07 million ≈ 2.98

In the 2003 Livestock Census, the cattle population was 16.30 million and the buffalo population was 6.14 million, yielding a ratio of:

16.30 million ÷ 6.14 million ≈ 2.65

Both census periods show that the population of cows and bulls is about three times that of buffaloes.

Explanation

The Konkan region forms the coastal zone of Maharashtra, bounded by the Sahyadri hills on the east and the Arabian Sea on the west. Spanning a coastline of approximately 720 kilometers, it encompasses districts such as Thane, Palghar, Mumbai, Raigad, Ratnagiri, and Sindhudurg. Because of its direct and extensive access to the sea, the Konkan region is the primary area in the state where marine and sea water fishing is carried out.

Explanation

In situ water harvesting, also known as on-farm water harvesting, refers to the practice of capturing and storing rainwater directly in the soil profile where it falls, rather than harvesting it in external structures. Contour ploughing is a primary land management practice used to achieve this. By ploughing along the contour lines of a slope at a constant elevation, horizontal ridges and furrows are created across the path of downward-flowing water. These ridges act as physical barriers that reduce the velocity of surface runoff, giving water more time to infiltrate the ground and significantly increasing soil moisture levels in situ.

Explanation

When one digit is removed from the four-digit number 8062, the remaining three digits must form a valid three-digit number. A standard three-digit number cannot have a leading digit of 0.

Removing 8 yields 062, which is the two-digit number 62. Removing 0 yields the three-digit number 862. Removing 6 yields the three-digit number 802. Removing 2 yields the three-digit number 806.

Comparing the valid three-digit numbers 862, 802, and 806, the smallest is 802. This is obtained by removing the digit 6.

Explanation

The pattern of the given series involves multiplying each successive term by a consecutive integer and then adding 1.

Let Tₙ represent the n-th term of the series:

T₁ = 2 T₂ = 2 × 2 + 1 = 5 T₃ = 5 × 3 + 1 = 16 T₄ = 16 × 4 + 1 = 65 T₅ = 65 × 5 + 1 = 326

Following this established mathematical rule, the next term in the series is calculated as:

T₆ = 326 × 6 + 1 = 1956 + 1 = 1957

Explanation

To find Raju's birth date, we calculate backward from 23rd August 2008.

Raju's age on 23rd August 2008 is 1 year and 9 days.

Subtracting 1 year from 23rd August 2008 gives 23rd August 2007. Subtracting 9 more days from 23rd August 2007 (23 - 9) gives 14th August 2007 as his date of birth.

To find the day of the week on 14th August 2007, we calculate the total number of days between 14th August 2007 and 23rd August 2008: The year 2008 is a leap year, so the period from 14th August 2007 to 14th August 2008 has 366 days (since 29th February 2008 falls within this period). The period from 14th August 2008 to 23rd August 2008 is 9 days. Total days = 366 + 9 = 375 days.

Dividing the total days by 7 to find the number of odd days: 375 ÷ 7 = 53 weeks and 4 remainder days (odd days).

Since 23rd August 2008 is a Saturday, we count backward by 4 days to find the day on 14th August 2007: Saturday - 4 days = Tuesday.

Therefore, Raju's birthday falls on a Tuesday.

Explanation

The coding pattern is established by shifting each letter of the word forward by a decreasing sequence of integers starting from 5. In the word BEAT, B shifts forward by 5 positions to become G, E shifts forward by 4 positions to become I, A shifts forward by 3 positions to become D, and T shifts forward by 2 positions to become V. Applying this identical logic to the word SOUP, S shifts forward by 5 positions to yield X, O shifts forward by 4 positions to yield S, U shifts forward by 3 positions to yield X, and P shifts forward by 2 positions to yield R, resulting in the code XSXR.

Explanation

The given relationship follows a mathematical pattern where the first number is the square of the second number, represented by the relation:

y = √x

For the first pair, we have:

√289 = 17

Applying the same relation to the second pair with x = 729, we get:

√729 = 27

Explanation

Each letter is assigned its corresponding numerical position in the English alphabet, where A = 1, B = 2, and so on. The value for each word is calculated by doubling the sum of the numerical positions of its individual letters.

For DEF: D = 4, E = 5, F = 6 Sum = 4 + 5 + 6 = 15 Value = 15 × 2 = 30

For KLM: K = 11, L = 12, M = 13 Sum = 11 + 12 + 13 = 36 Value = 36 × 2 = 72

Following the same logic for QRS: Q = 17, R = 18, S = 19 Sum = 17 + 18 + 19 = 54 Value = 54 × 2 = 108

Explanation

The coding pattern follows a simple shift of three positions forward in the English alphabetical sequence for each letter. For the word PUBLIC: P (16th letter) + 3 = S (19th letter) U (21st letter) + 3 = X (24th letter) B (2nd letter) + 3 = E (5th letter) L (12th letter) + 3 = O (15th letter) I (9th letter) + 3 = L (12th letter) C (3rd letter) + 3 = F (6th letter)

Applying this same +3 shift rule to the word BIRD yields: B (2nd letter) + 3 = E (5th letter) I (9th letter) + 3 = L (12th letter) R (18th letter) + 3 = U (21st letter) D (4th letter) + 3 = G (7th letter)

The resulting code is ELUG.

Explanation

By analyzing the letter-to-digit mappings in the given coded words: From 12345 = TIGER, the digits map directly as 1 to T, 2 to I, 3 to G, 4 to E, and 5 to R. From 876 = MOB, the digits map directly as 8 to M, 7 to O, and 6 to B.

Applying these mapped values to decode 128645, we substitute each digit in sequence: 1 becomes T, 2 becomes I, 8 becomes M, 6 becomes B, 4 becomes E, and 5 becomes R. Assembling these decoded letters in order yields TIMBER.

Explanation

Mohan starts at the origin point. His movement can be tracked step-by-step on a standard two-dimensional coordinate system.

First, he travels 2 km North, which places him 2 km North of the starting point.

Next, he turns right, which is towards the East, and walks 4 km. This positions him 2 km North and 4 km East of the origin.

He then turns right again, which points him South, and walks 2 km. This southward walk of 2 km completely cancels out his initial northward walk of 2 km, bringing him back to the East-West baseline, exactly 4 km East of the origin.

Finally, while facing South, he turns left, which directs him East again, and walks 4 km.

To find his final distance and direction from the origin, we combine his eastward displacements. He walked 4 km East in the second step and another 4 km East in the final step. This results in a total distance of 8 km to the East from his starting position.

Explanation

Rearranging the letters of each option reveals a specific category:

Option 1 rearranges to HINDI, which is a language. Option 2 rearranges to MARATHI, which is a language. Option 3 rearranges to URDU, which is a language. Option 4 rearranges to NEPAL (a country) or PANEL, neither of which is a language.

Thus, the fourth set of alphabets is the odd one out.

Explanation

The coding scheme alternates between adding 1 and subtracting 1 to successive digits of the number. For the number 24685, the pattern is: 2 + 1 = 3 4 - 1 = 3 6 + 1 = 7 8 - 1 = 7 5 + 1 = 6 This gives 33776.

Applying this exact pattern to 86125: 8 + 1 = 9 6 - 1 = 5 1 + 1 = 2 2 - 1 = 1 5 + 1 = 6 This results in 95216.

Explanation

To find the relationship, we can break down the statement made by Uday to Sudhir:

Sudhir's mother's sister is Sudhir's maternal aunt.

Sudhir's maternal aunt's son is Sudhir's maternal cousin.

The aunt of Sudhir's maternal cousin on the maternal side is the sister of the cousin's mother, which is Sudhir's mother.

Since this aunt is Uday's mother, Sudhir's mother must be Uday's mother.

This directly implies that Uday and Sudhir share the same mother and are brothers.

Explanation

The relationship between the number of workers, time taken, and work done is given by the chain rule formula:

(M₁ × T₁) / W₁ = (M₂ × T₂) / W₂

where M represents the number of herons, T represents the time in minutes, and W represents the number of fishes eaten.

Given: M₁ = 5 herons T₁ = 5 minutes W₁ = 5 fishes M₂ = 1 heron W₂ = 1 fish

Substituting these values into the formula:

(5 × 5) / 5 = (1 × T₂) / 1

5 = T₂

T₂ = 5 minutes

Explanation

By comparing the coded statements, the code for each individual word can be determined.

Comparing the code 324 for "Light is bright" and 629 for "Child is beautiful", the common number is 2 and the common word is "is". Therefore, 2 represents "is".

Comparing the code 324 for "Light is bright" and 4758 for "I prefer bright clothes", the common number is 4 and the common word is "bright". Therefore, 4 represents "bright".

For the phrase "Light is bright" coded as 324, the numbers 2 and 4 correspond to "is" and "bright". This leaves the remaining number 3 to represent the remaining word "Light".

Explanation

Rajan is the son of Kumar. Kumar is the father-in-law of Rajani, which means Rajani is married to Kumar's son. Since Rajan is Kumar's son, Rajani is married to Rajan. Sheela is the daughter of Rajani, which makes her the daughter of Rajan as well. Therefore, Rajan is the father of Sheela.

Explanation

The series 6, 14, 22, 30 increases by a constant difference of 8 at each step (14-6=8, 22-14=8, 30-22=8). Following this arithmetic progression, the next term is obtained by adding 8 to 30, giving 38. This confirms the series follows a simple linear pattern with a common difference of 8.

Explanation

The formula to find the angle θ between the hour hand and the minute hand of a clock is θ = |30H - 11/2 M|, where H is the hour and M is the minutes.

Substituting H = 3 and M = 30 into the formula:

θ = |30 × 3 - 11/2 × 30| θ = |90 - 165| θ = 75°

An angle of 75° is almost 90°.

Explanation

The given information establishes a clear relative height order among the three individuals. Since Anil is taller than Snehal, the relation is represented as Anil > Snehal. Because Snehal is taller than Nikhil, this relation is Snehal > Nikhil. Combining these two relations gives the overall height order of Anil > Snehal > Nikhil. This sequence shows that Nikhil is the shortest and Snehal is the middle one in height, meaning Snehal is not the shortest.

Explanation

By comparing the letters of the words GREAT and CHART with their corresponding symbols in the coded forms, the individual letter codes are determined through direct substitution:

G is coded as ⊙ R is coded as + E is coded as × A is coded as = T is coded as ÷ C is coded as - H is coded as *

Applying these individual symbol codes to the word TEACHER:

T becomes ÷ E becomes × A becomes = C becomes - H becomes * E becomes × R becomes +

Combining these symbols in order yields the coded word ÷ × = - * × +.

Explanation

The relationship is based on the primary duty or function associated with the role. Just as the primary function associated with a saint is worship, the primary duty of a policeman is to provide security.

Explanation

Mercury is the only metal in this group that exists in a liquid state at standard room temperature and pressure, possessing a very low melting point of -38.83 °C, which makes it distinct and the odd one out.

Explanation

By converting each letter in the sequence to its corresponding numerical position in the English alphabet, we get: F = 6 J = 10 M = 13 O = 15 Q = 17 T = 20

Analyzing the differences between consecutive numbers: From 6 to 10 is +4 From 10 to 13 is +3 From 13 to 15 is +2 From 15 to 17 is +2 From 17 to 20 is +3

The pattern of differences is symmetric: +4, +3, +2, +2, +3. Following this pattern, the next difference in the sequence must be +4.

Adding 4 to the last position: 20 + 4 = 24

The 24th letter of the alphabet is X.

Explanation

According to Statement (i), all lamps are poles. This means that the set of lamps is entirely contained within the set of poles. Since all lamps are poles, it is a logical necessity that some poles are lamps. Therefore, conclusion (B) follows directly from Statement (i).

Explanation

The coding follows a pattern where each letter in the word is shifted forward by two positions in the English alphabetical order.

For the word MOHAN: M is shifted by two letters to O O is shifted by two letters to Q H is shifted by two letters to J A is shifted by two letters to C N is shifted by two letters to P

Applying the same pattern to MUNNA: M is shifted by two letters to O U is shifted by two letters to W N is shifted by two letters to P N is shifted by two letters to P A is shifted by two letters to C

This gives the coded word OWPPC.

Explanation

The coding scheme splits the letters of the word based on their positions.

First, the letters at the odd positions (1st, 3rd, 5th, 7th, 9th) are written in their forward order. For THEREFORE, these letters are T, E, E, O, and E, which gives TEEOE.

Second, the letters at the even positions are written in reverse order from right to left (8th, 6th, 4th, 2nd). For THEREFORE, these letters are R, F, R, and H, which gives RFRH.

Combining both parts results in TEEOERFRH.

Applying this exact logic to HELICOPTER:

The letters at the odd positions (1st, 3rd, 5th, 7th, 9th) in forward order are H, L, C, P, and E, which gives HLCPE.

The letters at the even positions (10th, 8th, 6th, 4th, 2nd) in reverse order are R, T, O, I, and E, which gives RTOIE.

Combining these two parts results in HLCPERTOIE.

Explanation

The universal statement asserts that every single individual belonging to the class of criminals will receive punishment without exception. Since punishment is guaranteed for all, it logically eliminates any possibility of any criminal being pardoned or spared. Therefore, the conclusion that no criminal will be pardoned under any circumstances directly and absolutely follows from the given statement.

Explanation

This is a direct letter-to-digit substitution code. By matching the letters from the given words to their corresponding digits:

From UNITY (76423): U corresponds to 7 N corresponds to 6 I corresponds to 4 T corresponds to 2 Y corresponds to 3

From SOLIDARITY (8754910423): S corresponds to 8 O corresponds to 7 L corresponds to 5 I corresponds to 4 D corresponds to 9 A corresponds to 1 R corresponds to 0 I corresponds to 4 T corresponds to 2 Y corresponds to 3

Using these established mappings to write UNITARY: U is 7 N is 6 I is 4 T is 2 A is 1 R is 0 Y is 3

Placing these digits in order yields 7642103.

Explanation

By the transitive property of inequality, if x < y and y < z, then x < z.

Combining the given inequalities: a < b and b < c implies a < c. Furthermore, a < c and c < d implies a < d.

The inequality a < d is mathematically equivalent to d > a.

Explanation

The pattern followed in each row relates the middle number to the sum of the two outer numbers:

Middle number = (First number + Third number) × 3

Applying this formula to each row:

First row: (16 + 24) × 3 = 40 × 3 = 120

Second row: (23 + 17) × 3 = 40 × 3 = 120

Third row: (34 + 26) × 3 = 60 × 3 = 180
