DSSSB MTS Official Paper (Held On: 12 May, 2026 Shift 2) (Previous Year Paper)

Given Statement:

L < M < N > R ≥ S

Conclusions:

I: S < N → True (Since N > R and R ≥ S, therefore N > S, which means S < N.)

II: L = R → False (From the given statement, no definite relationship can be established between L and R. Hence, L = R cannot be concluded.)

Therefore, only Conclusion I is true.

Hence, the correct answer is “Option 2”.

Seven boxes I, J, K, L, M, N and O are kept one over the other but not necessarily in the same order.

1. Only J is kept above K.
2. Only two boxes are kept between K and O.
3. Only L is kept below I.
4. N is not kept immediately above O.

Final Arrangement:

M is kept fourth from the top.

Hence, the correct answer is “Option 1”.

A, B, C, D, Q, R and S are sitting around a circular table, facing the centre of the table.

1. Only three people sit between R and S when counted from the left of R.
2. Only three people sit between D and B when counted from the right of B.
3. C sits to the immediate right of D.
4. A is an immediate neighbour of B as well as S.

A sits second to the left of Q.

Hence, the correct answer is “Option 3”.

There are 17 such even digits that are immediately preceded by an odd digit and immediately followed by an odd digit.

Hence, the correct answer is "Option 2".

Additional Information

Given Statement:

L ≤ M > N > R ≥ S

Conclusions:

I: L = N → False (From the statement, L ≤ M and M > N. No definite relationship can be established between L and N. Therefore, L = N does not follow.)

II: S < M → True (Since M > N > R ≥ S, it follows that M is greater than S. Therefore, S < M is definitely true.)

Therefore, only Conclusion II is true.

Hence, the correct answer is “Option 1”.

A,B,C,D,Q,R and S are sitting around a circular table facing the centre of the table.

1. R sits to the immediate left of A.

सही उत्तर बुद्ध के अवशेषों है।

मुख्य बिंदु

• स्तूप एक टीले के समान गोलार्द्ध की संरचना है, जिसका उपयोग बौद्ध धर्म में मुख्य रूप से भगवान बुद्ध या उनके प्रख्यात शिष्यों के पवित्र अवशेषों (जैसे दांत, अस्थि, या राख) को सुरक्षित रखने के लिए किया जाता है।
• ऐतिहासिक रूप से, बुद्ध के महापरिनिर्वाण के बाद उनके अवशेषों को आठ भागों में विभाजित किया गया था और उन पर प्रारंभिक आठ स्तूपों का निर्माण किया गया था, जिनमें कुशीनगर और पावा प्रमुख थे।
• अवशेषों को स्तूप के भीतर एक धातु-मंजूषा (Relic Casket) में रखा जाता है, जो इस संरचना को बौद्ध अनुयायियों के लिए एक अत्यंत पवित्र श्रद्धा और पूजा का केंद्र बनाती है।
• मौर्य सम्राट अशोक ने इन अवशेषों को पुनर्वितरित किया और पूरे भारतीय उपमहाद्वीप में लगभग 84,000 स्तूपों का निर्माण करवाया, जिनमें सांची का महान स्तूप सबसे प्रसिद्ध है।

 अतिरिक्त जानकारी

• स्तूप की संरचनात्मक विशेषताएं:
• अण्ड: स्तूप का विशाल गोल गुंबद जो ब्रह्मांड और शांति का प्रतीक है।
• हर्मिका: गुंबद के शीर्ष पर स्थित एक चौकोर बालकनी जैसी संरचना, जिसे देवताओं का निवास माना जाता है।
• तोरण: चारों दिशाओं में बने भव्य नक्काशीदार प्रवेश द्वार, जिन पर बुद्ध के जीवन से जुड़ी जातक कथाएं अंकित होती हैं।
• प्रदक्षिणा पथ: स्तूप के चारों ओर बना मार्ग जहाँ भक्त पवित्र अवशेषों के सम्मान में परिक्रमा करते हैं।
• स्तूपों का वर्गीकरण:
• शारीरिक स्तूप: जिनमें बुद्ध या उनके शिष्यों के प्रत्यक्ष शारीरिक अवशेष रखे जाते हैं।
• पारिभोगिक स्तूप: जिनमें बुद्ध द्वारा उपयोग की गई वस्तुएं (जैसे भिक्षा पात्र या चीवर) रखी जाती हैं।
• उद्देशिक स्तूप: जो बुद्ध के जीवन से जुड़ी महत्वपूर्ण घटनाओं या पवित्र स्थानों की स्मृति में बनाए गए थे।

The correct answer is Patiala.

Key Points

• The Fifth Indian Open Throws Competition 2026 is scheduled to be organized in Patiala, Punjab, marking it as a significant venue for track and field events in India.
• This specialized competition is sanctioned by the Athletics Federation of India (AFI) and focuses exclusively on throwing disciplines, including Shot Put, Discus Throw, Javelin Throw, and Hammer Throw.
• Patiala is a preferred location for such high-stakes athletic meets due to the presence of the Netaji Subhas National Institute of Sports (NSNIS), which offers world-class infrastructure and training facilities for elite athletes.
• The event serves as a vital qualification platform for Indian athletes seeking to meet the entry standards for major international tournaments like the World Athletics Championships and the Asian Games.
• The Indian Open Throws series was initiated to provide targeted competitive exposure to throwers, helping them refine their technique and performance in a specialized environment outside of general national championships.

 Additional Information

• Athletics Federation of India (AFI):
• It is the national governing body for athletics in India, responsible for selecting the national team for the Olympic Games and other international events.
• Established in 1946, it operates under the guidance of World Athletics and the Asian Athletics Association.
• Netaji Subhas National Institute of Sports (NSNIS):
• Located in the Old Moti Bagh Palace, it is the academic wing of the Sports Authority of India (SAI) and the largest sports institute in Asia.
• It acts as the primary hub for national coaching camps and sports science research in India.
• Impact of Specialized Meets:
• Following the success of athletes like Neeraj Chopra, the AFI has increased the frequency of single-discipline events like the Indian Open Javelin Throw and Indian Open Throws to sustain the growth of field events.
• These competitions ensure that developmental-level athletes compete alongside international stars, fostering talent at the grassroots level.

The correct answer is Their value is included in final goods.

Key Points

• Intermediate goods are products used as inputs in the production of other goods or for resale within the same accounting year.
• The market value of final goods already incorporates the value of all intermediate goods used during the production process. For example, the price of a loaf of bread already accounts for the cost of flour, yeast, and electricity.
• Counting intermediate goods separately in National Income would lead to the error of Double Counting, where the same output is calculated multiple times, leading to an overestimation of the Gross Domestic Product (GDP).
• National Income measures the total value of final goods and services produced by the normal residents of a country to ensure an accurate reflection of economic growth and Productive Capacity.

 Additional Information

• Final Goods vs. Intermediate Goods:
• Final Goods: These are meant for final consumption by households or capital formation (investment) by producers. They have crossed the production boundary.
• Production Boundary: An imaginary line within which goods remain as long as value is being added to them. Once they leave this line, they become final products.
• Value Added Method:
• To avoid double counting, economists use the Value Added Method, which is the difference between the Value of Output and Intermediate Consumption at each stage of production.
• Formula: Value Added = Value of Output − Intermediate Cost.
• Inventory Exceptions:
• If an intermediate good remains unsold at the end of the year, it is treated as an inventory investment and is counted as a final good for that specific accounting period.

The correct answer is Assam and Arunachal Pradesh.

Key Points

• The Bhupen Hazarika Setu, also known as the Dhola-Sadiya Bridge, is a beam bridge that spans the Lohit River, which is a major tributary of the Brahmaputra River.
• It serves as a vital link between the states of Assam and Arunachal Pradesh, connecting the town of Dhola in the south to Sadiya in the north.
• With a total length of approximately 9.15 kilometers (5.69 miles), it is one of the longest bridges in India over water, providing 24x7 connectivity between upper Assam and eastern parts of Arunachal Pradesh.
• The bridge was officially inaugurated on May 26, 2017, by Prime Minister Narendra Modi, coinciding with the third anniversary of the NDA government.
• The construction of this bridge has reduced the distance between Rupai in Assam and Meka/Roing in Arunachal Pradesh by 165 kilometers, cutting travel time from 6 hours to just about 1 hour.

 Additional Information

• Strategic and Military Importance:
• The bridge is built to withstand the movement of 60-tonne battle tanks, including the Arjun and T-72 main battle tanks.
• It facilitates the rapid mobilization of Indian Army troops and equipment toward the Line of Actual Control (LAC) in Anjaw, Dibang Valley, and Lohit districts of Arunachal Pradesh.
• Cultural Significance:
• The bridge is named in honor of Dr. Bhupen Hazarika, a multifaceted artist, singer, and filmmaker from Assam, who was posthumously awarded the Bharat Ratna, India's highest civilian award, in 2019.
• Engineering and Development:
• The project was executed by the Ministry of Road Transport and Highways and the National Highways and Infrastructure Development Corporation Limited (NHIDCL) in partnership with Navayuga Engineering Company Ltd.
• The total cost of the project was approximately 2,056 crore Indian Rupees.

The correct answer is February 1919.

Key Points

• Mahatma Gandhi established the Satyagraha Sabha in Bombay (now Mumbai) in February 1919 to protest against the enactment of the Rowlatt Act.
• The Rowlatt Act, formally known as the Anarchical and Revolutionary Crimes Act of 1919, was based on the recommendations of the Sedition Committee headed by Justice S.A.T. Rowlatt.
• The Sabha was formed as a platform to organize a nationwide resistance movement, as Gandhi sought to unite various political factions against the colonial government's repressive measures.
• Gandhi designated the Rowlatt Act as a Black Act because it allowed the British government to imprison individuals for up to two years without trial, effectively suspending the principle of Habeas Corpus.
• The formation of this Sabha marked Gandhi's first major entry into all-India politics, transitioning from localized peasant and labor struggles in Champaran, Kheda, and Ahmedabad to a national leadership role.

 Additional Information

• Impact of the Satyagraha Sabha:
• The Sabha mobilized members of the Home Rule Leagues and younger nationalists to take a pledge of non-violence and civil disobedience.
• The agitation led to the nationwide Hartal on 6^th April 1919, which was the first mass protest of its kind in India.
• The government's violent response to these protests culminated in the tragic Jallianwala Bagh Massacre on 13^th April 1919 in Amritsar.
• Legislative Context:
• The Act was passed by the Imperial Legislative Council despite unanimous opposition from Indian members like Madan Mohan Malaviya and Mohammed Ali Jinnah, who resigned in protest.
• The primary objective of the British was to retain the emergency powers they had exercised during World War I to suppress the rising tide of nationalist revolutionary activities.

The correct answer is 1928.

Key Points

• The Hindustan Socialist Republican Association (HSRA) was formally established in September 1928 during a historic meeting of young revolutionaries at the Feroz Shah Kotla ground in Delhi.
• The organization was a revamped version of the Hindustan Republican Association (HRA), which had become largely inactive after the British government cracked down on its members following the Kakori Train Action of 1925.
• The name change to include the word 'Socialist' was primarily championed by Bhagat Singh, reflecting the profound influence of Marxist ideologies and the Russian Revolution on the Indian revolutionary movement.
• Prominent leaders present at the founding meeting included Chandrashekhar Azad, who was appointed the Commander-in-Chief of the Hindustan Socialist Republican Army, along with Bhagat Singh, Sukhdev Thapar, Shivaram Rajguru, and Phanindra Nath Ghosh.
• The core objective of the HSRA was the establishment of a Socialist Republic of India through an armed revolution, aiming to end both foreign imperialism and domestic exploitation.

 Additional Information

• Hindustan Republican Association (HRA):
• Founded in October 1924 in Kanpur by Ram Prasad Bismil, Sachindra Sanyal, and Jogesh Chandra Chatterjee.
• Its primary document, 'The Revolutionary', advocated for a federal system based on universal suffrage and was distributed across Northern India in 1925.
• Major Revolutionary Actions:
• In December 1928, HSRA members assassinated police officer J.P. Saunders in Lahore to avenge the death of the veteran leader Lala Lajpat Rai.
• On April 8, 1929, Bhagat Singh and Batukeshwar Dutt exploded non-lethal smoke bombs in the Central Legislative Assembly to protest the Public Safety Bill and the Trade Dispute Bill.
• The intellectual framework of the group was further explained in the manifesto 'The Philosophy of the Bomb', written by Bhagwati Charan Vohra as a rebuttal to the criticisms of Mahatma Gandhi.
• The HSRA effectively ceased to exist as an organized body after the martyrdom of Chandrashekhar Azad in Alfred Park, Allahabad, in February 1931, and the execution of Bhagat Singh, Sukhdev, and Rajguru in March 1931.

The correct answer is Isoquant.

Key Points

• An Isoquant, often referred to as an Equal Product Curve, represents all possible combinations of two factors of production (typically Labor and Capital) that yield the same level of total output.
• In Consumer Theory, an Indifference Curve maps combinations of two goods that provide a consumer with the same level of Utility or satisfaction; thus, the Isoquant is its direct equivalent in Production Theory.
• Both curves are characterized by a negative slope, indicating that if the use of one input (or good) decreases, the other must increase to maintain the same level of output (or utility).
• The convexity to the origin of an Isoquant is explained by the Marginal Rate of Technical Substitution (MRTS), which parallels the Marginal Rate of Substitution (MRS) found in indifference curve analysis.
• Just as an Indifference Map shows multiple levels of satisfaction, an Isoquant Map displays different levels of production, where higher curves represent greater quantities of Total Product.

 Additional Information

• Budget Line
• It represents the combinations of goods a consumer can purchase given their Disposable Income and Market Prices.
• In the theory of production, the equivalent concept is the Isocost Line, which shows combinations of inputs that cost the same total amount.
• Average Cost Curve
• This curve illustrates the Per-Unit Cost of production and is typically U-shaped in the short run.
• Its shape is dictated by the Law of Variable Proportions and Economies of Scale rather than substitution between inputs.

The correct answer is Because countries differ in population size.

Key Points

• Average income, also known as Per Capita Income, is calculated by dividing the total income (National Income) of a country by its total population.
• Total income is an ineffective measure for comparison because it fails to account for the number of people who must share that wealth; consequently, a country with a high total income but a massive population may have a lower standard of living than a smaller nation with a lower total income.
• Since different countries have significantly varying population sizes, comparing total income would lead to misleading conclusions regarding the economic welfare of an average citizen.
• By using the average income, economists can normalize the data to reflect resource availability per individual, facilitating a fairer comparison between nations like India and smaller European nations.
• The mathematical representation is: Average Income = Total Income / Total Population.

 Additional Information

• World Bank Classification:
• The World Bank uses Per Capita Income as the primary criterion in its World Development Reports to classify countries into high-income, middle-income, and low-income categories.
• In 2017, countries with a per capita income of USD 12,056 per annum and above were called rich countries, while those with USD 955 or less were called low-income countries.
• Limitations of Average Income:
• While useful for comparison, average income hides income disparities. It does not indicate the distribution of wealth, meaning a high average could still coexist with extreme poverty for the majority.
• Human Development Index (HDI):
• To provide a more holistic view of development, the UNDP publishes the HDI, which incorporates health indicators (life expectancy) and educational attainment alongside income levels.

• Rajasthan was the first state to adopt the Panchayati Raj system on October 2, 1959, in Nagaur district.

The correct answer is It functioned as a link between Sanskrit and later regional languages..

Key Points

• Apabhraṃśa represents the final stage of the Middle Indo-Aryan (MIA) period, serving as the critical evolutionary transition toward the New Indo-Aryan (NIA) languages.
• Literally meaning 'corrupt' or 'deviated', the term was used by ancient grammarians like Patanjali and Bhartrihari to denote dialects that strayed from the rigid rules of Classical Sanskrit.
• It flourished primarily between the 6^th century AD and the 13^th century AD, acting as a linguistic bridge that simplified the complex inflected system of Sanskrit and Prakrit into the more analytical structures of modern languages.
• The language was extensively used in medieval literature, particularly by Jain scholars and Siddha poets, preserving the cultural and linguistic continuity of northern and western India.
• It directly gave birth to several modern vernaculars; for instance, Sauraseni Apabhraṃśa led to Hindi and Punjabi, while Magadhi Apabhraṃśa evolved into Bengali, Assamese, and Odia.

 Additional Information

• Linguistic Classification:
• Old Indo-Aryan: Comprises Vedic Sanskrit (c. 1500 BCE) and Classical Sanskrit (c. 500 BCE), characterized by complex grammar and eight cases.
• Middle Indo-Aryan: Includes Pali (associated with Theravada Buddhism), various Prakrits (such as Maharashtri and Sauraseni), and Apabhraṃśa.
• New Indo-Aryan: Modern regional languages that emerged post-1000 AD following the Apabhraṃśa stage.
• Contextual Clarifications:
• The Mauryan Empire (c. 322−185 BCE) utilized Magadhi Prakrit for administrative purposes and the Edicts of Ashoka, centuries before Apabhraṃśa became prominent.
• The Mughal Empire (1526−1857 AD) adopted Persian as the official court and administrative language, though Urdu emerged from the Khari Boli dialect during this era.
• Vedic hymns were preserved through an oral tradition in Archaic Sanskrit, predating the Middle Indo-Aryan linguistic shifts.

The correct answer is Luni River.

Key Points

• The Luni River is the only major integrated river system in the Thar Desert (also known as the Great Indian Desert), making it the primary source of water for this arid region.
• It originates in the Pushkar Valley of the Aravalli Range near Ajmer, at an altitude of approximately 550 meters, and flows for a total length of about 495 kilometers.
• Geographically, the river flows in a south-westerly direction through the districts of Pali, Jodhpur, Barmer, and Jalore in Rajasthan before terminating in the marshy lands of the Rann of Kutch in Gujarat.
• The river is characterized as ephemeral, meaning its flow is highly dependent on the Southwest Monsoon; it remains dry for most of the year except during the rainy season.
• A unique scientific feature of the Luni River is its salinity; the water is fresh in its upper reaches but becomes increasingly saline after passing Balotra due to high salt content in the desert soil.

 Additional Information

• Sabarmati River:
• Originates in the Aravalli Range of Udaipur district and is one of the major west-flowing rivers in India, passing through Ahmedabad and Gandhinagar.

The correct answer is Neutralization reaction producing carbon dioxide and soluble salts.

Key Points

• The effectiveness of the mixture lies in the Acid-Base Neutralization reaction. Lemon juice contains Citric Acid (a weak organic acid), while baking soda is Sodium Bicarbonate (a weak base).
• When these two substances combine, they undergo a chemical reaction represented by the equation: 3NaHCO₃ + H₃C₆H_{5}O₇ → Na₃C₆H₅O₇ + 3H₂O + 3CO₂}.
• The reaction produces Carbon Dioxide ($CO_{2}$) gas, which is visible as effervescence or rapid bubbling. These gas bubbles provide mechanical agitation, helping to physically lift and loosen tough food particles, grease, and stains from the surface of the utensils.
• The process also forms Sodium Citrate, a soluble salt. This salt acts as a chelating agent, which binds to metal ions in hard water and helps in breaking down grease and mineral deposits, making them easier to rinse away.
• The mixture maintains a slightly alkaline or acidic balance depending on the ratio, but the primary cleaning power comes from the combination of chemical dissolution and physical bubbling.

 Additional Information

• Sodium Bicarbonate (Baking Soda):
• Chemical Formula: NaHCO₃.
• It acts as a mild abrasive, which helps in scrubbing surfaces without causing heavy scratches on metal utensils.
• It is effective at deodorizing by neutralizing acidic odor molecules.
• Citric Acid (Lemon Juice):
• Chemical Formula: C₆H_8}O₇.
• It is particularly efficient at removing alkaline stains, such as limescale or calcium deposits, due to its acidic nature.
• It possesses antibacterial properties, making it a natural disinfectant for kitchen environments.
• Comparison of Mechanisms:
• While Oxidation (Option 4) is common in bleach-based cleaners, it is not the primary mechanism for a lemon-soda mix.
• Hydrolysis (Option 3) typically requires stronger bases or higher temperatures to break down fats effectively compared to the bubbling action of neutralization.

The correct answer is Tropical evergreen forests.

Key Points

• Tropical evergreen forests are restricted to heavy rainfall areas typically exceeding 200 cm annually, coupled with a very short dry season.
• The vegetation is luxuriant and displays a multilayered structure including trees, shrubs, and creepers, with dominant trees reaching heights of 60 metres or more.
• These forests are predominantly located in the Western Ghats, the island groups of Lakshadweep and Andaman and Nicobar, upper parts of Assam, and along the Tamil Nadu coast.
• Because there is no specific period for trees to shed their leaves simultaneously, these forests appear vibrant green throughout the year.
• Commonly found commercial species in these biomes include Ebony, Mahogany, Rosewood, Rubber, and Cinchona.
• The fauna of these regions often includes elephants, monkeys, lemurs, and the one-horned rhinoceros in the jungles of Assam and West Bengal.

 Additional Information

• Tropical deciduous forests:
• Commonly known as monsoon forests, they are the most widespread forest type in India.
• They exist in regions receiving rainfall between 70 cm and 200 cm and are subdivided into Moist and Dry deciduous categories.
• Montane forests:
• These occur in mountainous regions where temperature decreases with increasing altitude, leading to distinct vegetation belts.
• Examples include wet temperate forests found between 1000 and 2000 metres and alpine vegetation at altitudes above 3600 metres.
• Mangrove forests:
• Located in coastal areas influenced by tides, where mud and silt accumulate.
• The Sundarbans in the Ganga-Brahmaputra delta is the largest mangrove area, famous for the Sundari trees and the Royal Bengal Tiger.

The correct answer is It requires a significant temperature difference (of at least 20 degree C) between surface and deep water..

Key Points

• Ocean Thermal Energy Conversion (OTEC) is a process that produces electricity by utilizing the temperature gradient between the warm sun-heated surface water and the cold deep ocean water.
• The primary technical constraint for an OTEC plant is the thermal efficiency, which is governed by the laws of thermodynamics; a small temperature difference results in very low Carnot efficiency.
• For the system to yield net positive energy (generating more power than consumed by the pumps), a minimum temperature difference of approximately 20°C (36°F) is essential between the surface and depths of about 800 to 1000 meters.
• This geographical requirement restricts the viable deployment of OTEC infrastructure mostly to tropical and subtropical maritime zones where surface waters remain consistently warm throughout the year.

 Additional Information

• Types of OTEC Systems:
• Closed-Cycle: Uses fluids with low boiling points, such as ammonia or propane, to rotate a turbine.
• Open-Cycle: Directly evaporates the warm seawater in a low-pressure environment to produce steam, which also acts as a source of desalinated fresh water.
• Hybrid-Cycle: Combines features of both systems to optimize energy extraction and water production.
• Environmental Impact: OTEC is a renewable energy source that provides a baseload power supply, unlike solar or wind, which are intermittent. It does not produce methane or significant greenhouse gases.
• Comparison: Unlike Tidal Energy, which depends on gravitational forces and high tides, OTEC depends solely on solar thermal absorption by the oceans.

The correct answer is Growth of bacteria.

Key Points

• The conversion of milk into curd is a biochemical process initiated by the addition of a small amount of curd, which acts as an inoculum or starter.
• This starter culture contains millions of bacteria, primarily belonging to the genus Lactobacillus, such as Lactobacillus acidophilus.
• When added to warm milk, these bacteria multiply rapidly by utilizing the lactose (milk sugar) present in the milk as a substrate.
• Through the process of fermentation, the bacteria convert lactose into lactic acid.
• The production of lactic acid increases the acidity of the milk, causing the milk protein called casein to coagulate and form a solid mass.
• This coagulation changes the texture and flavor of the milk, resulting in the formation of curd.

 Additional Information

• Lactobacillus:
• It is a probiotic bacterium that is beneficial for human gut health and aids in digestion.
• The optimal temperature for the growth of these bacteria in milk is generally between 30°C and 40°C.
• Action of Yeast:
• Yeast is a unicellular fungus used in alcoholic fermentation and the baking industry to produce carbon dioxide and ethanol.
• It is not responsible for the standard lactic acid fermentation required to make curd.
• Nutritional Value:
• The fermentation process improves the nutritional quality of milk by increasing the content of Vitamin B₁₂.
• Curd is often easier to digest than milk for individuals with lactose intolerance because the bacteria have already broken down some of the lactose.

The correct answer is Article 51A(g).

Key Points

• Article 51A(g) was incorporated into the Indian Constitution via the 42^nd Amendment Act, 1976, based on the recommendations of the Swaran Singh Committee.
• This Article belongs to Part IV-A and establishes the Fundamental Duty of every citizen to protect and improve the natural environment, encompassing forests, lakes, rivers, and wildlife, and to show compassion for living creatures.
• In the celebrated M.C. Mehta series of public interest litigations (PILs), the Supreme Court of India interpreted this duty as not just a moral obligation for citizens but also a directive for State action.
• The judiciary linked the duty under Article 51A(g) with Article 21 (Right to Life), ruling that the right to a wholesome environment is an integral part of the fundamental right to life, thereby making environmental protection a mandatory constitutional mandate.
• Through these interpretations, the Public Trust Doctrine and the Polluter Pays Principle were strengthened, compelling the government to take proactive measures against industrial pollution and ecological degradation.

 Additional Information

• Article 18:
• This provision deals with the Abolition of Titles, ensuring that the State does not confer any title other than military or academic distinctions to maintain social equality.
• Article 25:
• Guarantees the freedom of conscience and the right to freely profess, practice, and propagate religion, subject to public order, morality, and health.
• Article 32:
• Described by Dr. B.R. Ambedkar as the 'Heart and Soul' of the Constitution, it provides the Right to Constitutional Remedies, allowing citizens to approach the Supreme Court for the enforcement of Fundamental Rights through various writs.
• Article 48A:
• A Directive Principle of State Policy (DPSP) that complements 51A(g) by explicitly directing the State to endeavor to protect and improve the environment and safeguard the forests and wildlife of the country.

The correct answer is Statement 1-Correct & Statement 2- Correct.

Key Points

• The 2011 Census indicates that the Jain community is highly urbanized, with their population largely concentrated in the western industrial and commercial hubs of Maharashtra, Gujarat, and Rajasthan. Concurrently, Buddhists are most significantly concentrated in Maharashtra, where they constitute approximately 77% of the total Buddhist population in India, largely due to the Navayana movement. Hence, statement 1 is correct.
• Apart from Maharashtra, the Buddhist population is concentrated in the Himalayan belt and North-Eastern regions. Major areas include Sikkim, Arunachal Pradesh, and the Ladakh region (which was part of Jammu & Kashmir during the 2011 Census). They also form significant clusters in Tripura and the Lahaul and Spiti district of Himachal Pradesh. Hence, statement 2 is correct.

 Additional Information

• Religious Composition (2011 Census):
• Muslims: They represent 14.2% of the population, with the highest concentration in Lakshadweep, Jammu & Kashmir, and West Bengal.
• Christians: Making up 2.3%, they are primarily located in the South Indian state of Kerala, Goa, and the North-Eastern states like Nagaland, Mizoram, and Meghalaya.
• Sikhs: They constitute 1.7% of the population and are predominantly located in Punjab, followed by Haryana and Delhi.
• Minority Status: Jains (0.4%) and Buddhists (0.7%) are recognized as National Minorities under the National Commission for Minorities Act, 1992.

The correct answer is Xylem transports water while phloem distributes prepared food.

Key Points

• Xylem is a specialized vascular tissue in plants responsible for the unidirectional transport of water and dissolved inorganic minerals from the roots up to the leaves and other parts of the plant.
• The movement in xylem is primarily driven by physical forces such as transpiration pull (evaporation of water from leaves) and root pressure, which allow water to overcome gravity.
• Phloem is the vascular tissue that facilitates translocation, the bidirectional transport of organic nutrients, mainly sucrose, from source regions like leaves to sink regions like roots, fruits, and developing buds.
• Unlike the passive movement in xylem, phloem transport is an active process that requires metabolic energy in the form of ATP to load sugars into the conduction cells.
• Together, xylem and phloem form the vascular system, providing structural support and ensuring the efficient distribution of resources required for growth and metabolism.

 Additional Information

• Cellular Composition of Xylem:
• Consists of four types of cells: tracheids, vessel elements, xylem parenchyma, and xylem fibers.
• Most xylem cells are dead at maturity and have thick, lignified walls to provide mechanical strength to the plant.
• Cellular Composition of Phloem:
• Composed of sieve tube elements, companion cells, phloem parenchyma, and phloem fibers.
• Companion cells are specialized parenchyma cells that manage the metabolic activities of sieve tubes, which lack a nucleus at maturity.
• Other Plant Functions:
• Photosynthesis occurs primarily in the chloroplasts of the mesophyll cells in leaves, not in the vascular tissues.
• Seed production is the function of the reproductive system (flowers, ovules, and pollen) rather than the transport system.

The correct answer is Lactic acid.

Key Points

• Curd is produced through the process of anaerobic fermentation, where Lactic Acid Bacteria (LAB), specifically Lactobacillus acidophilus, are added to milk.
• These bacteria utilize lactose, the primary sugar found in milk, and metabolize it into lactic acid as a byproduct of their energy production.
• The chemical formula for lactic acid is $C_{3}H_{6}O_{3}$, and its accumulation significantly lowers the pH level of the milk, making it acidic.
• This increase in acidity causes the milk protein, known as casein, to denature and coagulate, which creates the solid, thick consistency of curd.
• The distinct sour taste of curd is a direct sensory result of the high concentration of hydrogen ions released by the lactic acid during the fermentation process.
• During this conversion, Lactobacillus also improves the nutritional quality of the milk by increasing the content of Vitamin B12.

 Additional Information

• Acetic Acid:
• Commonly known as ethanoic acid, it is the primary ingredient in vinegar after water.
• It is produced by Acetobacter species through the oxidation of ethanol and is widely used as a food preservative and pickling agent.
• Citric Acid:
• A weak organic acid that occurs naturally in citrus fruits like lemons, oranges, and pomelos.
• It is a key intermediate in the citric acid cycle (Krebs cycle), which is a fundamental metabolic pathway in aerobic organisms.
• Hydrochloric Acid (HCl):
• A strong mineral acid that is highly corrosive and serves as a major component of gastric juice in the stomach.
• It facilitates the digestion of proteins by activating enzymes like pepsin and acts as a barrier against ingested pathogens.
