🔑 Show Answer Key — Set 1

1. Citizens vote to choose their representatives. Popular sovereignty means that ultimate political authority belongs to the people; elections are a central way in which citizens authorise representatives to govern on their behalf.
2. Opportunity cost.
3. Powerful individuals are treated above the law.
4. Shortage.
5. Earthquakes occur when accumulated stress is suddenly released along faults as tectonic plates converge, diverge or slide past one another. They are therefore frequent near plate boundaries and active fault zones, including the Himalayan belt, northeast India, the Andaman–Nicobar region and the Kachchh area. Scientists can map hazard zones and monitor seismic activity, but they cannot yet predict the exact time, place and magnitude of an earthquake reliably.
6. A national party has recognised electoral strength across several states, whereas a state party meets recognition criteria within a particular state. National parties usually contest and organise across much of India and address Union-level as well as state issues; state or regional parties concentrate more strongly on a state or region and its specific interests. Recognition criteria also differ: for example, a party may qualify nationally by recognition in at least four states, while state recognition can follow specified vote-and-seat performance within one state. Their reserved symbols operate according to their category and recognition.
7. Yes. Regulation is needed for safety, competition and fairness, but excessive or unpredictable rules can raise compliance costs, delay entry, discourage investment and protect established firms from competitors. For example, a very low price ceiling on a product without support for supply can cause shortages and black markets; unnecessarily complex permits can keep small firms from entering; and a poorly set minimum price can create an unsold surplus. Good regulation addresses a clear market failure, is transparent and proportionate, and is reviewed using evidence.
8. Governments may cap the prices of essential medicines so that lifesaving treatment remains affordable, regulate electricity or public-transport tariffs where a service has few alternative suppliers, and sell basic food grains at subsidised issue prices to eligible households. They may also use minimum prices for selected farm produce to protect cultivators from an exceptionally low market price. Such measures seek affordability, food or health security, protection from monopoly power or income stability, though poorly designed controls can cause shortages, surpluses or fiscal costs.
9. I would choose writing. It allowed societies to preserve accounts, laws, agreements and administrative orders beyond one person’s memory. It later carried literature, scientific observation and religious ideas across generations and distances. Other choices such as irrigation or metallurgy are defensible, but writing permanently transformed government, commerce and the accumulation of knowledge.
10. Varṇa was a broad fourfold conceptual classification—Brāhmaṇa, Kṣhatriya, Vaiśhya and Śhūdra—often expressed in prescriptive texts. Jāti referred to the many actual birth-based social communities found locally, commonly associated with occupation, marriage networks and customary practice. Jātis multiplied as crafts specialised, tribes and migrating groups entered settled society, regions developed distinctive customs, and occupations or communities acquired separate identities. The large number and local variety of jātis could not fit neatly into four varṇas.
11. Important features included the growth of territorial kingdoms and empires, organised revenue and military systems, and continuing roles for local bodies and assemblies. Society contained diverse varṇas, jātis, occupations and regional communities rather than one unchanging arrangement. Agriculture and irrigation remained the base of the economy, while roads, ports, coins and guilds expanded crafts and trade. Education, philosophical inquiry, literature, religious traditions and Bhakti also flourished and showed both continuity and change.
12. The Rule of Law places citizens and public officials under laws that are known and applied equally. It prevents arbitrary rule, protects rights, provides legal remedies and allows courts to review government action. Without it, power or status could determine how a person is treated, making elections and constitutional guarantees ineffective.
13. A model answer for many Indian urban regions is intense-rain flooding, heat waves and possible earthquake shaking. Mitigation should identify safe shelters and evacuation routes, keep drains clear, preserve wetlands, publish emergency contacts, practise school drills, secure heavy furniture, store water and first-aid supplies, and issue heat and rain alerts. The exact plan must be adjusted to the local hazard map rather than assuming every region faces the same risk.
14. Parliament represents citizens at the national level, makes laws, approves taxation and public spending, and examines the work of the Union government. It promotes accountability through questions, debates, committees, votes and scrutiny of the budget. Participation begins when citizens elect members through universal adult franchise and continues when people petition representatives, express views and follow proceedings. Opposition parties and public debate ensure that more than the governing majority is heard.
15. Some urgent choices must be made with incomplete information, but reliable data usually makes economic decisions far more effective. Without it, needs, costs and opportunity costs may be estimated badly and resources misallocated. For example, a city deciding how much water to supply needs sound data on population, reservoir levels, leakage and seasonal demand. Otherwise it may overinvest in an unnecessary project or fail to prevent a shortage. Uncertainty should therefore be acknowledged and decisions updated as better evidence arrives.
16. Decipherment could reveal the language used by the Harappans and identify personal names, offices and place names. If the inscriptions contain administrative or commercial records, they might explain taxation, ownership, trade, weights and the government of cities. Religious formulas or longer texts could illuminate beliefs, rituals, social groups and historical events. It would let historians test conclusions now drawn mainly from archaeology.
17. Atmospheric pressure acts on the body from every direction, while fluids and air inside the body exert an outward pressure that balances it. Because the pressures are normally balanced and change gradually, we do not feel the enormous total force.
18. A common example is freshwater. It is scarce in many Indian towns, yet leaking pipes, overflowing tanks, inefficient irrigation and unnecessary washing waste it. Metering large users, repairing leaks, harvesting rainwater, reusing treated greywater and wastewater, using drip irrigation and informing users about local supply can reduce waste. Groundwater withdrawal should also be monitored so that use does not continually exceed recharge.
19. The sabhā and samiti allowed members of the community to deliberate on important matters and required the rājā to consult others rather than act entirely alone. They could influence leadership, policy, war and collective affairs, making authority more accountable. In modern India, Parliament and State Legislatures debate and approve laws and budgets, local elected bodies represent communities, and courts review whether public authority acts according to law. These institutions are not identical to Vedic assemblies, but they similarly distribute and check power.
20. The ECI prepares and revises electoral rolls, fixes election schedules, registers and recognises political parties, allocates symbols, supervises nominations and campaigning, enforces the Model Code of Conduct, arranges polling and security, counts votes, declares results and resolves specified disputes. It also introduces accessibility and technology measures and coordinates officials across states. All are connected, but impartial supervision of the entire process is most important: accurate rolls or counting alone cannot produce a fair election if campaigning, polling or enforcement is biased.
21. Tree canopies reduce the force of rainfall, roots bind soil and vegetation slows surface runoff. Deforestation removes this protection, leaving loose soil exposed to rain and wind. Runoff then increases, carrying away topsoil and cutting rills or gullies; slopes may also become less stable and more prone to landslides. Erosion in turn makes natural regeneration harder by removing fertile soil.
22. Historians use these ages to organise the past according to the main materials and technologies visible in archaeological remains, especially tools. The sequence helps trace changes from stone working to metallurgy and the new occupations, trade and social organisation that followed. It does not mean that progress was uniform or that one material immediately replaced another; different societies adopted technologies at different times and often used old and new materials together.

Answer briefly. (Answer all questions.)

5.How would democracy be affected if citizens stopped following laws and civic responsibilities? Explain with an example.[2]

6.Critically examine why pure economic systems rarely exist in reality. Assess the limitations of such systems and justify why a mixed economy is often considered a more practical and effective approach in real-world contexts.[2]

13.Write a paragraph on what democracy means to you as a young citizen.[2]

14.With the help of your teacher, find out more about the Code of Hammurabi. Why was it important? Do you think it was fair to all sections of society? Give reasons for your answer.[2]

15.Look at the major trade routes of early India (Fig 5.12). How do you think these routes helped people in the exchange of goods, skills, beliefs, and cultural practices.[2]

16.Describe the role of the king, important officers, and the methods used to govern large territories.[2]

What does this source tell us about the economic role of guilds? b. Why were guilds trusted with money deposits? c. Identify the donor and the donees from the given source.[2]

21.Why do you think people’s wants keep changing over time? How does this affect production in an economy? Why cannot all our wants be satisfied?[2]

22.Imagine you are a Neolithic farmer. Describe one day of your life. What challenges would you face that a hunter-gatherer would not?[2]

🔑 Show Answer Key — Set 2

1. Shortage.
2. Citizens vote to choose their representatives. Popular sovereignty means that ultimate political authority belongs to the people; elections are a central way in which citizens authorise representatives to govern on their behalf.
3. Opportunity cost.
4. Powerful individuals are treated above the law.
5. Democracy would weaken because rights depend on citizens and institutions respecting common laws and accepting responsibility for public life. Disorder, mistrust and unequal treatment would grow, and governments would find it harder to protect everyone’s freedoms. For example, if people ignored traffic laws and damaged public property during a protest, they would endanger others and divert public resources, undermining lawful participation even though peaceful protest itself is democratic.
6. A pure market economy can allocate many goods responsively but may produce inequality, monopolies, under-provision of public goods and unpriced environmental harm. A fully planned economy can pursue social priorities and coordinate resources, but concentrated decision-making may lack local information, consumer choice and incentives to improve. Real societies need both private initiative and collective provision. A mixed economy uses markets for decentralised choice and innovation while government supplies public goods, protects consumers, supports vulnerable groups, corrects market failures and regulates competition. Its success still depends on capable, transparent government and fair rules.
7. Advisors’ texts often describe how rulers ought to govern, not necessarily what they actually did. Their authors usually wrote from elite, courtly and male viewpoints and may have justified royal authority or ignored groups with little access to writing. Manuscripts were also copied and altered over time. Historians therefore compare them with inscriptions, coins, archaeology, literature and evidence from different regions before drawing conclusions about practice or ordinary people’s lives.
8. Rising demand can accelerate mining, logging, water withdrawal, energy use and waste, causing depletion, pollution, habitat loss and climate stress. A balance is possible if prices and rules reflect environmental costs, resources are extracted within regenerative limits, durable goods are repaired and reused, waste is recycled and cleaner technologies are adopted. Consumers must also distinguish important needs from wasteful consumption. The aim is not to end all production but to satisfy wants without destroying the resource base needed by future generations.
9. Fertile soil, dependable water and plants and animals suitable for domestication helped early communities farm, settle and produce surpluses. River valleys also supported irrigation, transport and trade, making large cities possible. Yet the same environment brought floods, droughts, changing river courses and, where irrigation was poorly managed, waterlogging or salinity. People therefore had to build embankments and canals, store grain and cooperate in managing water.
10. The Constitution establishes that authority comes from the people and creates representative institutions at different levels. It guarantees fundamental rights, universal adult franchise and equality, distributes powers among institutions, provides an independent judiciary and makes government accountable to law. It also states duties and shared values by which citizens can judge public action. These rules protect democracy from depending only on the wishes of current rulers or a temporary majority.
11. Yes, provided elections are genuinely free, fair, inclusive and periodic. They give citizens an equal vote, allow them to choose or remove representatives, authorise governments and make rulers answerable for performance. Parties and candidates also present alternatives and organise public debate. Elections are therefore central to democracy, though they must operate with rights, the Rule of Law, transparent institutions and active citizenship between polling days.
12. a. Social media can widen access to information, let citizens discuss public issues, organise lawful action, hear diverse voices and question representatives quickly. b. Irresponsible use can spread false information, hatred and harassment, create closed echo chambers, invade privacy or manipulate opinion. Citizens strengthen democracy when they verify claims, disagree respectfully, protect personal data and obey the law.
13. To me, democracy means that every person has equal dignity and a voice in decisions that affect our common life. Even before I can vote, I can learn about the Constitution, listen to different views, question misinformation, follow laws and duties, care for public property and participate in school or community initiatives. Democracy gives rights, but it also asks me to use freedom responsibly and to defend the rights of people with whom I may disagree.
14. Hammurabi’s Code was an important written collection of Babylonian laws covering matters such as property, contracts, family relations, wages and offences. Publishing rules and penalties gave officials and subjects a common legal reference and reveals how the state regulated society. It was not fair by modern standards: penalties often varied with a person’s social rank and gender, and enslaved people did not receive the same treatment as elites or free persons.
15. Routes such as the Uttarāpatha and Dakṣhiṇāpatha connected inland settlements, capitals and production centres with ports. Traders carried textiles, metals, spices and other goods, while artisans and travellers transmitted techniques and styles. Monks, pilgrims and teachers moved along the same networks, spreading religious ideas, languages, stories and artistic forms. Connections between land routes and Indian Ocean ports also brought Indian communities into contact with Central Asia, Southeast Asia and the Roman world.
16. The king was expected to protect the realm, uphold dharma, administer justice, lead or supervise war and promote welfare. Ministers advised him, while officers collected revenue, kept accounts, maintained law and order, commanded troops and governed provinces or districts. Large states were divided into administrative units and linked through roads, messengers and intelligence networks. Records, inspections, taxation, local authorities and alliances with subordinate rulers helped the centre govern distant regions.
17. India must make participation and representation meaningful for all citizens despite social and economic inequality, discrimination and barriers faced by marginalised groups. Other challenges include misinformation, polarisation, misuse of money or influence in politics, weak accountability and declining respect for reasoned disagreement. Democratic institutions and citizens can respond through fair elections, transparent government, independent scrutiny, civic education, responsible media use and consistent protection of constitutional rights and the Rule of Law.
18. The Sindhu–Sarasvatī, Mesopotamian, Egyptian and Chinese civilisations arose in different river regions and created their own scripts, political arrangements, beliefs, art and architecture. Nevertheless, agricultural surpluses supported cities, craft specialists and social hierarchies in each. They developed administration, long-distance trade, writing or record-keeping, bronze technology and major public or ritual works. The shared features reflect similar problems of organising dense settled populations, while their distinct forms show independent development.
19. Rivers supplied drinking and irrigation water, renewed fertile soil through silt, supported fish and animals, and provided routes for travel and trade. These advantages encouraged reliable surpluses and urban growth. But destructive floods could kill people and ruin fields, while drought or a shifting channel could cut off water. Irrigation also required collective labour and could cause salinity or disputes over distribution. Settlements therefore needed storage, drainage, embankments and organised water management.
20. a. Guilds acted not only as professional associations but also as financial institutions: they accepted deposits, invested or used the capital and paid fixed interest that supported a continuing endowment. b. They were organised, durable bodies with collective funds, rules and a reputation to protect, so donors expected them to preserve capital and make regular payments. c. The donor was Uṣhavadāta, son of Dinika and son-in-law of king Nahapāna. The cave and the income from the endowment were given to members of the Buddhist Saṁgha of any sect and origin who lived there; the money itself was deposited with two weavers’ guilds at Govadhana.
21. Wants change with age, income, technology, advertising, fashion, social conditions and newly available products. Producers respond by changing what they make, how much they make and the resources and methods they use. All wants cannot be satisfied because land, labour, time, capital and natural resources are limited and have alternative uses. Choosing one use therefore sacrifices another, creating an opportunity cost.
22. At sunrise I might feed domesticated animals, inspect the field, repair a fence or irrigation channel, weed or harvest a crop, and then dry and store grain and mend pottery or tools. My family’s survival would depend on staying near the settlement and completing work at the right season. Unlike a hunter-gatherer, I would worry about crop failure, pests, livestock disease, protecting stored grain, maintaining land and water works, and resolving claims over fields.

🔑 Show Answer Key — Set 3

1. Powerful individuals are treated above the law.
2. Shortage.
3. Citizens vote to choose their representatives. Popular sovereignty means that ultimate political authority belongs to the people; elections are a central way in which citizens authorise representatives to govern on their behalf.
4. Opportunity cost.
5. a. Thiruvananthapuram is near the equator and the sea, whose moderating influence keeps the annual temperature range small. b. Chennai lies largely in the rain shadow during the south-west monsoon; in October–November retreating north-east winds cross the Bay of Bengal, collect moisture and rain on the Coromandel coast, often with cyclones. c. Leh lies in the Himalayan rain shadow and receives little monsoon rain; its limited precipitation is spread through occasional summer showers and winter snowfall associated with western disturbances rather than one intense rainy season.
6. Education aimed not only to transmit subjects and practical skills but also to develop self-discipline, responsibility, truthfulness and respect for others. Knowledge without ethical restraint could be misused, while moral training helped learners apply it to family and social duties. Such an ideal could strengthen trust, preserve learning across generations and prepare people for responsible roles. Its social benefit depended, however, on how widely and fairly education was made available.
7. a. In Country A’s multi-party system, voting allows citizens to choose among competing programmes and can replace one governing party with another. In Country B, citizens may vote, but a one-party system removes meaningful party competition and greatly limits the ability to choose an alternative government. b. I would choose Country A because its written constitution, periodic elections, voting rights and party competition provide the strongest political participation and accountability. A higher material standard of living cannot by itself replace political freedom.
8. A model plan begins by mapping bare slopes, drainage lines, construction sites and streambanks. Plant native grasses, shrubs and trees; use contour trenches or terraces on slopes; keep ground covered with mulch; stabilise streambanks; and route storm water through permeable drains and recharge pits. Restrict dumping, sand removal and grazing in vulnerable patches. Residents and the local body should inspect the sites before and after monsoon and repair small gullies before they expand.
9. Sellers may cut prices to clear large inventories, attract buyers in a highly competitive period and sell a much greater quantity. The lower price causes movement down the demand curve, increasing quantity demanded; if the discount reflects greater available supply, the new equilibrium has a lower price and higher quantity. Consumers gain from lower prices, but sellers can also gain through faster stock turnover, economies of scale, platform visibility and sales of related items. A price simply fixed below equilibrium without extra supply would instead create excess demand or a shortage.
10. Commercial aeroplanes commonly fly in the lower stratosphere or near the tropopause because this layer is comparatively stable, has little cloud or vertical weather disturbance, and allows smoother flight than the turbulent troposphere below.
11. Farming made life more secure in some ways but also created new challenges. It provided a more regular food supply and encouraged permanent settlements, storage and specialised crafts. At the same time, farmers had to perform continuous seasonal labour and could lose much of their food to droughts, floods, pests or crop disease. Settled life also increased disputes over land and exposure to infectious disease.
12. In the early Vedic period, a jana or clan was led by a rājā whose authority was checked by assemblies. With settled agriculture, larger territories and taxation, janapadas and mahājanapadas emerged; some were monarchies and others gaṇas or saṁghas. Magadha’s expansion culminated in the Mauryan Empire, which used a capital, provinces, officials, taxation, an army and communication routes to govern a vast territory. Gupta administration retained kingship and officials but allowed greater authority to provincial, local and sometimes hereditary or feudatory rulers.
13. One reasonable order is: d. Strengthens democracy; a. Opportunity to choose my representative; c. Opportunity to change the non-performing representative; b. Makes me a responsible person. Voting strengthens the whole representative system by giving government public authority. It lets me select the candidate I trust and, in the next election, hold a poor performer accountable. Participating thoughtfully also develops civic responsibility. Other orders are valid when supported by democratic reasons.
14. Internal movements are powered mainly by heat within the Earth, including residual heat from its formation and heat generated by radioactive decay. This heat drives convection in the mantle and the movement of lithospheric plates. Gravity and differences in density also contribute to the sinking, rising and adjustment of crustal material.
15. a. Movie ticket and popcorn—complementary. b. Eraser and pencil—complementary. c. Laptop and desktop computer—substitutes for many uses. d. Air conditioner and cooler—substitutes. e. Notebook and pen—complementary. f. Apple and banana—substitutes. g. Mobile and earphones—complementary. The classification depends on typical use: substitutes satisfy a similar want, while complementary goods are commonly used together.
16. Present choices determine the infrastructure, skills, technology, institutions, debt and environmental conditions inherited by future citizens. Investment in education, health, research and resilient infrastructure can raise later productivity and opportunity. By contrast, exhausting groundwater, polluting ecosystems or borrowing for wasteful consumption can create lasting costs. Because resources used today cannot simultaneously serve another purpose and some damage is difficult to reverse, decision-makers should compare long-term social benefits and opportunity costs rather than focus only on immediate gains.
17. A market system generally gives consumers and private producers the widest direct freedom to choose, and competition and the possibility of profit can encourage innovation. But freedom is unequal when income or market power is highly unequal, and markets may neglect public goods or environmental costs. A well-designed mixed economy can therefore promote innovation effectively while protecting competition, funding basic research and public services, and regulating harmful conduct. The conclusion depends on institutions, not only the system’s label.
18. a. Demand for diesel cars is likely to rise because they are a substitute for petrol cars, although expectations about diesel prices also matter. b. Demand for electric cars is likely to rise for the same substitution reason. c. Demand for accessories used mainly with petrol cars is likely to fall because those accessories and petrol-car use are complementary; general accessories may be less affected. d. Demand for public transport is likely to rise as private petrol travel becomes more expensive. These are shifts in demand caused by the price of a related good.
19. Differences in language, customs and occupations arise because communities have developed in varied geographical settings and through distinct historical, cultural and economic experiences. Climate, resources, migration, trade, political institutions and inherited traditions shape how people live. The chapter adds that these variations coexist with cultural connections that create an underlying unity and shared identity within India.
20. The Himalayas formed when the Indian and Eurasian plates converged, compressing and folding sediments. The Peninsular Plateau is part of an ancient stable crustal block shaped by uplift, faulting and long erosion; rifting and faulting helped form features such as the Narmada–Tapi troughs and western coastal margin. The Andaman and Nicobar arc lies near a convergent boundary with tectonic and volcanic activity. The Northern Plains, although related to the Himalayan foredeep, were built mainly by river deposition and therefore show endogenic and exogenic processes working together.
21. Most earthquakes and volcanoes cluster along plate margins. At convergent margins one plate may descend, melt and feed volcanoes while friction produces strong earthquakes. At divergent margins rising magma creates new crust, volcanic activity and shallow earthquakes. At transform margins plates grind past one another and release stored stress as earthquakes. The belts around the Pacific and along mid-ocean ridges therefore reflect the global pattern of plate boundaries.
22. a. The situation reflects participation, discussion, respect for different opinions, equality in voting and collective decision-making. b. Voting gives every member a defined voice and supplies a peaceful, transparent method of choosing among alternatives. c. A majority decision makes action possible when complete agreement cannot be reached, provided minority rights and views are respected. d. Representatives should implement the agreed decision fairly, explain their actions, use resources responsibly, remain accountable and continue listening to all members, including those who disagreed.
