Distribution of Population

Correct answer: B. Economic activities and connectivity can compensate for limited local resources

Explanation: B is correct. Trade links and transport networks can bring food, fuel, and other supplies from elsewhere, so a region need not obtain everything from its immediate surroundings. Trade and services also create jobs that attract and support a large population. Limited local resources can still be a constraint, but they do not always prevent high population concentration.

Correct answer: A. By the balance between economic attraction and environmental harm

Explanation: A is correct. Good jobs and wages can attract people, while severe pollution can discourage settlement because of health risks and poorer living conditions. Some people may accept those costs for work, while others may avoid the area or live farther away. The resulting population distribution reflects both economic attraction and environmental harm; neither factor alone determines it.

Correct answer: B. Consider both natural change and migration.

Explanation: Correct answer: B. Rising mortality affects natural population change, while outward migration changes how people are distributed between places. To understand the resulting population pattern, both processes must be considered. Looking at only one would leave out the effect of the other; area size alone cannot explain these changes.

Correct answer: C. Services improve quality of life, but working-age people may migrate without livelihood opportunities.

Explanation: The correct answer is C. A hospital and school provide important services and can make a place more liveable. However, working-age adults also need jobs and income. If these opportunities are absent, they may move elsewhere even when services are available, limiting the region’s ability to retain its population.

Correct answer: A. A new residential concentration may develop

Explanation: Direct answer: A. Closing an airport releases a large, already urban piece of land for another use. If it is redeveloped for housing and supported by roads, public transport, water, schools and other services, many households may move into the area. This can create a new residential concentration and redistribute people within the city. Option B is wrong because land-use change directly affects where homes and residents are located. C is wrong because adding housing generally creates capacity; it does not necessarily reduce population. D is too narrow because the change can affect housing, services, land values and movement, not only flights. The key idea is that population distribution responds to the conversion of land from one urban use to another when the new use is accessible and serviced.

Correct answer: A. Fertile plains, water availability and favourable climate attract settlement

Explanation: Direct answer: A. World population is uneven because physical and human conditions vary from place to place. Fertile plains provide productive land and easier construction and transport. Reliable water supports domestic use, farming and industry. A favourable climate can make living and working conditions more comfortable. These advantages often combine with roads, cities, markets and employment to attract settlement. Option B is wrong because the same latitude can contain deserts, forests, plains and mountains with very different populations. C is wrong because steep slopes, difficult transport and limited cultivable land often restrict dense settlement in mountains, although some valleys are populous. D is wrong because political boundaries matter, but they do not always outweigh relief, water, climate and economic opportunity. Memory cue: explain concentration through land, water, climate and livelihoods together.

Correct answer: D. Accessibility-led displacement and residential restructuring

Explanation: Option D is correct. A metro can make station areas more accessible and attractive, which may increase demand for nearby land and housing. If rents and property costs rise, some low-income tenants may have to move to less expensive areas. This changes both where people live and the social composition of station neighbourhoods. The example shows a possible indirect effect; it does not mean displacement will occur in every metro area.

Correct answer: D. Some graduates may leave despite local opportunities because housing is unaffordable

Explanation: Option D is correct. Graduates may consider local jobs and education, but they also need to be able to afford housing. If housing costs rise beyond what some people can manage, they may move to a less expensive place even when opportunities remain in the university city. This is a possible effect, not a certainty for every graduate.

Correct answer: B. The worker population may decline while a smaller, higher-income skilled group remains

Explanation: Option B is correct. Automation may replace some jobs, leading some workers to leave the region. At the same time, skilled workers who operate or maintain advanced systems may remain and earn more. The result could be a smaller workforce alongside a more highly paid skilled group. This is a plausible outcome, not a guaranteed one.

Correct answer: D. Improved accessibility may encourage more travel and development along the corridor

Explanation: Option D is correct. An expressway can initially ease congestion by adding road capacity. Improved access may then encourage more trips and attract housing or businesses along the corridor. As travel and development increase, the added capacity may fill up and congestion may return. This is a possible explanation, not a claim that every new road must cause more congestion.

Correct answer: A. High visitor numbers do not guarantee that families will settle there permanently.

Explanation: Option A is correct. More visitors indicate increased tourism activity, but seasonal jobs may offer work only for part of the year. Workers may leave during the off-season or keep their permanent homes elsewhere. Visitor numbers therefore do not, by themselves, show how many people will settle in the region permanently.

Correct answer: B. Commuter settlements may grow even without an increase in local jobs.

Explanation: Option B is correct. Better roads make regular travel to a nearby city easier. Some people may continue living in a village for its housing, family ties, or other reasons while travelling to the city for work or services. This can support the growth of commuter settlements; improved access does not automatically empty villages.

Correct answer: D. Some households may choose more distant, less expensive residential areas.

Explanation: Option D is correct. If people need to travel to a central office less often, some may choose a more distant home that offers more space or lower costs. Over time, this could shift some residential growth toward suburbs or other outer areas. It is a possible trend, not a guarantee that central neighbourhoods will empty.

Correct answer: A. High tourism revenue does not necessarily create high local incomes.

Explanation: Option A is correct. Tourism revenue is the money generated by visitor spending, but it does not all necessarily reach local households. If outside companies receive much of the profit and local jobs pay little, residents may gain limited income and security. The region may therefore attract fewer people seeking a stable, long-term livelihood than its high visitor numbers suggest.

Correct answer: B. Households with children may be more likely to seek safer residential areas.

Explanation: Option B is correct as a possible pattern. High wages may attract workers, but toxic pollution can pose health risks. Some households with children may place particular importance on health and choose to live in a safer area, even if adults commute to jobs in the industrial zone. People’s choices vary, so this is not an inevitable response for every family.

Correct answer: D. Social filtering may occur according to people’s ability to recover from risk.

Explanation: Option D is correct. Rebuilding after repeated storms can be costly. Households with greater financial resources may be able to repair their homes and remain, while households with fewer resources may relocate. As a result, the social composition of the affected area can change; the population need not decline uniformly.

Correct answer: B. Families may increase housing demand in desirable school zones despite better transport.

Explanation: Option B is correct. Better metro service can make it easier to travel from homes farther away, but it does not remove a residential-zone requirement for school admission. Families who want access to a particular school may therefore continue to seek housing in its zone, increasing demand there. This is a possible effect, not a guaranteed outcome for every family.

Correct answer: B. People may live on one side of the border and commute to work on the other.

Explanation: Option B is correct. If housing is more affordable on one side of a border and jobs are more available on the other, some people may live in one country and commute to work in the other. This creates a separation between residential and workplace locations across the border, provided that crossing it for regular travel is practical.

Correct answer: C. Distress migration may decline as income risk is reduced

Explanation: C is correct. Growing different crops reduces reliance on any one crop, so a poor harvest of one crop may be partly offset by another. This can make farm income and food supplies more stable and may reduce the need for people to leave because of financial distress. The effect is not guaranteed: people may still move for work, education, or other reasons.

Correct answer: D. Reduced hazard risk versus accessibility benefits

Explanation: D is correct. A household may weigh the greater flood safety of central neighbourhoods against the better transport access of outer areas. The choice depends on how the household balances hazard exposure with access to jobs, schools, services, and other destinations. Neither safety nor transport access alone captures the trade-off.

Correct answer: A. Overcrowding and expansion toward under-served peripheral areas may increase

Explanation: A is correct. When population grows faster than housing, roads, water supply, sanitation, and other facilities, existing developed areas can become crowded. Some households may then move toward less costly peripheral areas, where services may not yet meet their needs. This pattern is possible rather than inevitable; faster population growth does not by itself eliminate infrastructure gaps or ensure even distribution.

Correct answer: B. Income opportunity versus hazard exposure

Explanation: B is correct. High wages can attract workers to live near factories, but housing in a sea-level-risk zone may expose them to flooding, evacuation, or property loss. Workers may weigh the income and shorter commute against those risks; some may instead commute from a safer area. The question describes a trade-off, not one outcome that applies to every worker.

Correct answer: B. Population may grow modestly rather than in proportion to the investment.

Explanation: B is correct. A logistics hub can attract workers and service providers, but automated systems may allow it to operate with relatively few employees. The city’s population may therefore increase without growing in proportion to the investment. This is a possible response, not a guaranteed prediction; the actual change also depends on jobs, services, and other local conditions.

Correct answer: A. More residents may be concentrated vertically in the central area.

Explanation: A is correct. Mixed-use high-rise buildings can place homes above shops, offices, and services, allowing more people to live on the same limited land. This can increase residential concentration in the centre. The result is possible, not guaranteed: housing costs, planning rules, and access to services also influence where people live.

Correct answer: A. Older residents without access to a private vehicle

Explanation: A is correct. When public transport declines, reaching shops, healthcare, and other services can become harder. Older residents who do not have access to a private vehicle may have fewer ways to make these trips, increasing their risk of spatial isolation. The effect can vary with the availability of nearby services and other transport options.
