  • b)
    USA
  • c)
    Singapore
  • d)
    England
Correct answer is option 'A'. Can you explain this answer?

Anjali Sharma answered
Roads
  • Road transport is the most economical for short distances compared to railways.
  • Freight transport by road is gaining importance because it offers door-to-door service
  • The quality of the roads varies greatly between developed and developing countries because road construction and maintenance require heavy expenditure.
  • In developed countries good quality roads are universal and provide long-distance links in the form of motorways, autobahns (Germany), and interstate highways for speedy movement.
  • Hence the correct answer is option 1.
  • Lorries, of increasing size and power to carry heavy loads, are common.

According to the Demographic Transition Theory, the third stage in a demographic cycle is marked by:
  • a)
    High mortality low fertility
  • b)
    Low fertility low mortality
  • c)
    High fertility high mortality
  • d)
    High fertility low mortality
Correct answer is option 'B'. Can you explain this answer?

Demographic Transition Theory
  • It predicts the shift in the population (birth and death rate) of an area.
  • This theory also studies the relationship between economic development and population growth.
Demographic cycle
  • According to the Demographic Transition Theory, the third stage is marked by low fertility low mortality.
  • High fertility and high mortality is the first stage in a demographic cycle.
  • At the beginning of the second stage, fertility remains high and increases population.
  • Then fertility starts to decline and leads to a low mortality rate.
  • This is the high fertility low mortality stage.
  • The third stage is where fertility and mortality decreases.
  • The last stage is the low fertility and low mortality stage, where both fertility and mortality even declines at a considerable rate.

Amita Das answered
Alluvial soil is the most widely spread and important soil. In fact, the entire northern plains are made of alluvial soils. These have been deposited by three important Himalayan river systems – the Indus, the Ganga and the Brahmaputra. Alluvial soils also extend in Rajasthan and Gujarat through a narrow corridor. Alluvial soil is also found in the eastern coastal plains particularly in the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri rivers. Apart from the size of their grains or components, these soils are also described on the basis of their age - old alluvial (bangar) and new alluvial (khadar). The bangar soil has higher concentration of kanker nodules than the khadar. It has more fine particles and is more fertile than the bangar.

Kunal Verma answered
True Statements

Statement 1: It took more than a century to achieve the mark of two billion people in 1927, but only 33 years to reach the three billion mark in 1960.

This statement is true. The world population took over a century to reach two billion in 1927, but the third billion was added in just 33 years in 1960. This was due to a combination of factors, including advances in medicine, increased food production, and improvements in sanitation.

Statement 2: The second stage of the demographic transition is the pre-industrial stage.

This statement is false. The second stage of the demographic transition is the transitional stage, not the pre-industrial stage. In the transitional stage, there is a decline in the death rate due to improvements in healthcare and sanitation, but the birth rate remains high. This leads to a rapid increase in population growth. The pre-industrial stage is the first stage of the demographic transition, characterized by high birth and death rates and slow population growth.

Conclusion

In conclusion, Statement 1 is true, and Statement 2 is false. The world population took over a century to reach two billion in 1927, but the third billion was added in just 33 years in 1960. The second stage of the demographic transition is the transitional stage, not the pre-industrial stage.

    Environmental determinism and possibilism
  • b)
    Structuralism and post modernism
  • c)
    Darwinism and Universalism
  • d)
    Humanism and possibilism
Correct answer is option 'A'. Can you explain this answer?

Nisha Sengupta answered
Environmental determinism and possibilism

Griffith Taylor introduced a new form of determinism called Neodeterminism or stop and go determinism, which lies between the ideas of environmental determinism and possibilism.

Environmental determinism is the belief that the physical environment, including factors such as climate, topography, and resources, determines the cultural and social development of a society. It suggests that human behavior and societal characteristics are primarily shaped by the environment in which they live. This perspective was prevalent during the late 19th and early 20th centuries when scholars sought to explain the differences in human societies based on their geographic surroundings.

On the other hand, possibilism is a contrasting viewpoint that suggests that while the environment may provide opportunities and constraints, it does not solely determine human behavior. Possibilism argues that humans have the ability to make choices and adapt to their environment. It emphasizes the role of human agency and cultural factors in shaping society.

Neodeterminism or stop and go determinism

Griffith Taylor's neodeterminism, also known as stop and go determinism, bridges the gap between these two ideas. It acknowledges that the environment does play a significant role in shaping human behavior and cultural development, but it also recognizes the agency and choices made by individuals and societies.

Instead of viewing the environment as a deterministic force that completely determines human behavior, neodeterminism suggests that it operates in a stop and go manner. This means that while the environment may provide certain opportunities or constraints, human agency and cultural factors can interrupt or redirect the deterministic influence.

Explanation of the correct answer

The correct answer to the question is option A - environmental determinism and possibilism. This is because Griffith Taylor's neodeterminism is positioned between these two ideas. It takes into account the importance of the environment in shaping human societies but also acknowledges the role of human agency and cultural factors. The other options listed in the question, such as structuralism and postmodernism, Darwinism and Universalism, or humanism and possibilism, do not directly relate to Griffith Taylor's neodeterminism.

How many stages does the demographic transition model have?
  • a)
    2
  • b)
    3
  • c)
    4
  • d)
    5
Correct answer is option 'D'. Can you explain this answer?

Anjali Sharma answered
There are 5 stages in the demographic transition model.
Stage 1: Death rates and birth rates are high and are roughly in balance, a common condition of a pre-industrial society. Population growth is very slow, influenced in part by the availability of food.
Stage 2: This is the "developing country" phase. Death rates drop rapidly due to improvements in food supply and sanitation, which increases life spans and reduces disease. Without a corresponding fall in birth rates, countries in this stage experience a large increase in population.
Stage 3: Birth rates fall due to access to contraception, increase in wages, urbanisation, an increase in the status and education of women, and other social changes. Population growth begins to level off.
Stage 4: Birth rates and death rates are both low in this stage. People born during stage 2 are now beginning to age and require the support of a dwindling working population. Birth rates may drop below replacement level, considered to be two children per family. This leads to a shrinking population. Death rates may remain consistently low, or they may increase slightly.
Some theorists include a fifth stage in which fertility rates begin to transition again to either above or below that which is necessary to replace the percentage of the population that is lost to death. Some say fertility levels decrease during this stage, while others hypothesize that they increase. Rates are expected to increase population in Mexico, India and the U.S. in the 21st century, and to decrease population in Australia and China.

Which of the following statements is/are true in context of manganese and its production in India?
  • a)
    It is an important raw material in iron industries.

    It is mainly associated with the Dharwar system.
  • c)
    Odisha is the leading producer of manganese.
  • d)
    All of the above
Correct answer is option 'D'. Can you explain this answer?

Amita Das answered
Manganese is an important raw material for smelting of iron ore and also used for manufacturing ferro alloys. Manganese deposits are found in almost all geological formations, however, it is mainly associated with the Dharwar system. Odisha is the leading producer of Manganese. Major mines in Odisha are located in the central part of the iron ore belt of India.

Directions: Read the following passage carefully:
The pressure on land resources is increasing with more demand for food production. This has forced farmers to develop land for agriculture production and adopt intensive and unsustainable land-use techniques that can cause high levels of soil erosion. Increasing pressures of urbanisation and industrialisation and anthropogenic activities such as building of roads, dams, construction activities are also increasing the rate of erosion of the soil in India. The different kinds and increasing extent of erosion contribute to rapid conversion of cultivable lands into wastelands. For example, recent evidence shows that about 20% of the total geographical area of the country has been converted into wastelands.
Since the causes of soil erosion differ from one area to the other, different methods such as contour tillage, contour bunding, construction of check dams, terrace farming etc are used to prevent erosion and improve soil quality.

Q. Which of the following is NOT an example of human intervention causing soil erosion?
  • a)
    Terrace farming
  • b)
    Road construction
  • c)
    Grazing of domestic animals
  • d)
    Adopting intensive land-use techniques
Correct answer is option 'A'. Can you explain this answer?

Amita Das answered
In the last paragraph, various techniques which are being used to control soil erosion have been mentioned. For example: contour tillage, contour bunding, terrace farming, etc. Thus, terrace farming is a human intervention that controls soil erosion instead of aggravating it. All other options are examples of human interventions which lead to soil erosion, transforming the cultivable lands into wastelands.

Resource Potential for Wind and Solar Energy in Rajasthan

Introduction:
Rajasthan, located in the northwestern part of India, has immense potential for renewable energy, particularly wind and solar power. The state's geographical location, vast open spaces, and favorable weather conditions make it an ideal destination for harnessing these resources.

Wind Energy Potential:
Rajasthan possesses a significant wind energy potential due to its geographical features and favorable wind patterns. The key factors contributing to the state's wind energy potential are:

1. Geographical Location: Rajasthan is situated on the western side of the Aravalli Range, which acts as a barrier to the southwest monsoon winds. As a result, the state experiences strong and consistent winds during the summer and monsoon seasons, making it an ideal location for wind energy generation.

2. Open Spaces: Rajasthan has vast stretches of flat, barren land that is ideal for setting up wind farms. These open spaces facilitate the installation of wind turbines, allowing for efficient harnessing of wind energy.

3. Wind Density: The state has a high wind density, particularly in regions such as Jaisalmer, Jodhpur, and Bikaner. The average wind speed in these areas ranges from 6 to 7 meters per second, which is considered favorable for wind power generation.

Solar Energy Potential:
Rajasthan is also endowed with abundant solar energy resources. The factors contributing to the state's solar energy potential are:

1. Sunlight Intensity: Rajasthan receives ample sunlight throughout the year due to its geographical location. The state experiences around 300 days of clear skies annually, resulting in high solar radiation levels and intense sunlight.

2. Large Land Availability: The state has vast stretches of barren land, making it suitable for the establishment of solar power plants. These open spaces provide ample opportunities for the installation of solar panels and the generation of solar energy.

3. Solar Irradiance: Rajasthan has one of the highest solar irradiance levels in India, with an average annual solar radiation of around 6-7 kWh/m²/day. This high solar irradiance ensures efficient conversion of sunlight into electricity through photovoltaic systems.

Conclusion:
Considering the favorable wind patterns, high wind density, abundant sunlight, and large land availability, Rajasthan stands as a potential resource for both wind and solar energy. The state has made significant progress in harnessing these renewable resources, with several wind farms and solar power plants already operational. Expanding the renewable energy sector in Rajasthan can contribute significantly to India's overall energy mix and help reduce dependence on fossil fuels, thereby promoting sustainable development.

Which of the following is NOT an institutional or technological reform in agriculture?
  • a)
    Shift in demand for organic produce
  • b)
    Subsidising fertilisers and pesticides
  • c)
    Digitalisation of retailing in agriculture
  • d)
    Provision of crop insurance by the government
Correct answer is option 'A'. Can you explain this answer?

Explanation:
The correct answer is option 'A' - Shift in demand for organic produce.

Reason:
Institutional or technological reforms in agriculture refer to changes in policies, practices, or technologies that aim to improve the efficiency, productivity, and sustainability of agricultural production. These reforms are typically implemented by governments or other institutions to address specific challenges or opportunities in the agricultural sector.

Let's examine each option to determine which one is not an institutional or technological reform in agriculture:

a) Shift in demand for organic produce:
This option refers to a change in consumer preferences and market demand for organic produce. While this shift in demand may influence the practices and strategies adopted by farmers and agribusinesses, it is not an institutional or technological reform implemented by the government or other institutions.

b) Subsidising fertilisers and pesticides:
This option refers to the provision of financial support or incentives by the government to farmers for the purchase of fertilizers and pesticides. This is an example of an institutional reform aimed at promoting the use of agricultural inputs to increase productivity.

c) Digitalisation of retailing in agriculture:
This option refers to the adoption of digital technologies and platforms for the marketing and distribution of agricultural products. The digitalization of retailing is a technological reform that aims to improve efficiency, transparency, and accessibility in agricultural value chains.

d) Provision of crop insurance by the government:
This option refers to the government's provision of insurance coverage to farmers against crop losses due to natural disasters, pests, or other risks. This is an institutional reform aimed at reducing the financial risks faced by farmers and promoting agricultural resilience.

In summary, the option that is NOT an institutional or technological reform in agriculture is a) Shift in demand for organic produce. While consumer demand for organic produce may influence agricultural practices, it is not a reform implemented by institutions or governments.

Anjali Sharma answered
Human resource development is the integrated use of training, organisation, and career development efforts to improve individual, group, and organisational effectiveness. 'R' and 'S' are the activities aimed at improving the skill level of an individual, such that the individual will be able to perform better at the workplace as a result of this training and these workshops. 'P' is incorrect as it itself is not a human development activity. Although the purpose for education loan is obtaining education, only education would be regarded as a human development activity. 'Q' is not a human resource development activity.

Anjali Sharma answered
Nature of Human Geography
  • The people begin to understand their environment and the forces of nature with the passage of time.
  • With social and cultural development, humans develop better and more efficient technology. 
  • They create possibilities with the resources obtained from the environment. Human activities create a cultural landscape.
  • The imprints of human activities are created everywhere; health resorts on highlands, huge urban sprawls, fields, orchards, and pastures in plains and rolling hills, ports on the coasts, oceanic routes on the oceanic surface, and satellites in the space.
  • The earlier scholars termed this as possibilism. Nature provides opportunities and human beings make use of these and slowly nature gets humanized and starts bearing the imprints of human endeavor.
  • Human geography studies the inter relationship between the physical environment and socio-cultural environment created by man. Hence, statement 1 is correct.
  • Elements of physical environment are land, water, soil, climate, vegetation, fauna. Hence, statement 2 is correct.
  • Elements of cultural environment are transport and communication, settlements, crops. Hence, statement 3 is correct.

Which of the following has the highest railway density of 1 km of railway for every 6.5 sq km of land?
  • a)
    Switzerland
  • b)
    Belgium
  • c)
    Denmark
  • d)
    Italy
Correct answer is option 'B'. Can you explain this answer?

Belgium has the highest railway density of 1 km of railway for every 6.5 sq km of land among the given options.

Railway density refers to the length of railway tracks in a country relative to the land area. It is an important measure to assess a country's transportation infrastructure and connectivity.

Here is a detailed explanation of why Belgium has the highest railway density among the given options:

1. Railway Density Calculation:
- Railway density is calculated by dividing the total length of railway tracks in a country by the land area.
- In this case, the railway density is 1 km of railway for every 6.5 sq km of land.
- The country with the highest railway density will have the smallest value in this ratio.

2. Railway Density in Switzerland:
- Switzerland is known for its efficient and extensive railway network. However, it has a relatively larger land area compared to Belgium.
- The Swiss Alps and mountainous terrain make it challenging to build railway tracks in certain regions.
- Therefore, Switzerland may have a lower railway density compared to Belgium.

3. Railway Density in Denmark:
- Denmark is a relatively small country with mostly flat terrain, which makes it easier to construct railway tracks.
- However, Denmark has a larger land area compared to Belgium.
- Therefore, the railway density in Denmark may be lower than in Belgium.

4. Railway Density in Italy:
- Italy has a diverse landscape, including mountainous regions, which can pose challenges in building railway infrastructure.
- Italy also has a larger land area compared to Belgium.
- Therefore, the railway density in Italy may be lower than in Belgium.

5. Railway Density in Belgium:
- Belgium is a small country with a highly developed railway network.
- Its compact size and relatively flat terrain make it easier to build and maintain railway tracks.
- Belgium has a well-integrated railway system connecting its major cities and also provides international connections.
- As a result, Belgium has the highest railway density among the given options.

In conclusion, Belgium has the highest railway density of 1 km of railway for every 6.5 sq km of land among Switzerland, Denmark, and Italy due to its small size and well-developed railway network.

Directions: Read the following passage carefully:
Haryali is a watershed development project which aims at enabling the rural population to conserve water for drinking, irrigation, fisheries and afforestation. Under this initiative, all ongoing area development programmes namely, Integrated Wastelands Development Programme (IWDP), Drought Prone Areas Programme (DPAP) and Desert Development Programme (DDP) will be implemented through Panchayati Raj Institutions w.e.f. April 2003. As the Watershed Development Programmes aim at holistic development of watershed areas, the convergence of all other non-land based programmes of Government of India, particularly those of the Ministry of Rural Development would enhance the ultimate output and lead to sustainable economic development of the village community. The ZP/DRDA therefore, shall take all-possible measures to ensure convergence of other programmes of the Ministry of Rural Development such as the Sampoorna Grameen Rozgar Yojana (SGRY), the Swarnjayanti Gram Swarozgar Yojana (SGSY) the Indira Awas Yojana (IAY), the Total Sanitation Campaign (TSC) and the Rural Drinking Water Supply Programme in the village chosen for the implementation of the watershed development projects.

The transformation took place when a retired army personnel, settled down in the village and took up the task of watershed development. He convinced villagers about the importance of family planning and voluntary labour; preventing open grazing, felling trees, and liquor prohibition.

Directions: In the question given below, there are two statements marked as Assertion (A) and Reason (R). Mark your answer as per the codes provided below.
Assertion (A): Kerala performs much better than Punjab and Gujarat in human development.
Reason (R): Per capita income governs the extent of human development.
  • a)
    Both A and R are true and R is the correct explanation of A.
  • b)
    Both A and R are true but R is not the correct explanation of A.
  • c)
    A is true but R is false.
  • d)
    A is false but R is true.
Correct answer is option 'C'. Can you explain this answer?

Prashanth Das answered
Assertion (A): Kerala performs much better than Punjab and Gujarat in human development.
Reason (R): Per capita income governs the extent of human development.

The correct answer is option 'C' - A is true but R is false.

Explanation:

Human Development Index (HDI)
- Human Development Index (HDI) is a measure of human development which takes into account factors such as life expectancy, education, and per capita income.
- It provides a comprehensive picture of a country's overall development and well-being.
- HDI is calculated based on three dimensions: a long and healthy life, knowledge, and a decent standard of living.

Kerala's Performance in Human Development
- Kerala has consistently performed much better than Punjab and Gujarat in terms of human development.
- The state has achieved a high level of human development despite having a lower per capita income compared to Punjab and Gujarat.
- This indicates that per capita income alone does not govern the extent of human development.

Reasoning Behind Kerala's High HDI
- Kerala's high HDI can be attributed to several factors:
- High literacy rate: Kerala has achieved a near-universal literacy rate, which has contributed to the improvement in education and knowledge indicators of HDI.
- Focus on healthcare: The state has invested heavily in healthcare infrastructure and services, resulting in high life expectancy and quality healthcare facilities.
- Social indicators: Kerala has achieved significant progress in reducing poverty, improving gender equality, and ensuring social inclusion, which are important components of human development.

Per Capita Income and Human Development
- While per capita income is an important factor in determining the standard of living, it is not the sole determinant of human development.
- Human development encompasses various dimensions beyond income, such as education, healthcare, and overall well-being.
- Countries or regions with higher per capita income may not necessarily have higher human development if other factors are not given due importance.

Conclusion
- The assertion that Kerala performs much better than Punjab and Gujarat in human development is true.
- However, the reason given that per capita income governs the extent of human development is false.
- Kerala's exceptional performance in human development can be attributed to its focus on education, healthcare, and social indicators, rather than solely relying on per capita income.

    Eastern Region
  • b)
    Northern Region
  • c)
    Western Region
  • d)
    Southern Region
Correct answer is option 'B'. Can you explain this answer?

Amita Das answered
Distribution of Population
  • India has a highly uneven pattern of population distribution. The percentage shares of population of the states and Union Territories in the country show that Uttar Pradesh has the highest population followed by Maharashtra, Bihar and West Bengal.
  • U.P., Maharashtra, Bihar, West Bengal, Andhra Pradesh along with Tamil Nadu, Madhya Pradesh, Rajasthan, Karnataka and Gujarat, together account for about 76 per cent of the total population of the country.
  • On the other hand, share of population is very small in the states like Jammu & Kashmir (1.04%), Arunachal Pradesh (0.11%) and Uttarakhand (0.84%) inspite of theses states having fairly large geographical area.
  • Another reason is landform structure. Northern Region are, generally, not more than 200 metres above mean sea level.
  • Most of the plains are formed by rivers and their tributaries. The rivers flow down the slopes of mountains and erode them. T
  • Generally, plains are very fertile. Construction of transport network is easy. Thus, these plains are very thickly-populated regions of the world.

Which of the following statements is true regarding subsistence economy?

    It is a market (protected thoroughly from fraud) that consistently produces technology.
  • b)
    Goods are produced to provide for oneself or one's family.
  • c)
    It is a type of agriculture characterized by high output per unit of land.
  • d)
    All of the above
Correct answer is option 'B'. Can you explain this answer?

Amita Das answered
In a subsistence economy, goods are produced to provide for oneself or one's family.
A subsistence economy is an economy directed to basic subsistence (the provision of food, clothing, shelter) rather than to the market. "Subsistence" is understood as supporting oneself at a minimum level. Often, the subsistence economy is moneyless and relies on natural resources to provide for basic needs through hunting, gathering, and agriculture. In a subsistence economy, economic surplus is minimal and only used to trade for basic goods, and there is no industrialization.

  • b)
    Only b
  • c)
    Both a and b
  • d)
    Neither a nor b
Correct answer is option 'C'. Can you explain this answer?

Anjali Sharma answered
The age-sex structure of a population refers to the number of females and males in different age groups. A population pyramid is used to show the age-sex structure of the population. The Japan pyramid has a narrow base and a tapered top showing low birth and death rates. The population growth in developed countries is usually zero or negative. Australia's age-sex pyramid is bell shaped and tapered towards the top. This shows birth and death rates are almost equal leading to a near constant population. Thus, both the statements are incorrect.
