Intensive subsistence farming is widely practiced in densely populated areas, particularly in countries like India and China.
Statement I: Correct. Due to high population pressure, land holdings are very small.
Statement II: Correct. Limited use of machinery and more reliance on manual labour is a key characteristic.
Statement III: Incorrect. It is not largely practised in Central Asia, but rather in South and Southeast Asia.
Statement IV: Correct. The yield per unit area is high, but due to heavy dependence on manual labour, the productivity per labour is low. So, the correct answer is (A): I, II and IV are correct.

The rearing of animals in ranches is indeed organized on a scientific basis. This approach is commonly referred to as "ranching," which involves the large-scale breeding and management of livestock, such as cattle, sheep, and horses, primarily for meat, wool, or other products. The scientific aspect of ranching includes the use of modern techniques in breeding, feeding, health management, and pasture management.
- Breeding Techniques:
Ranches apply genetic selection to improve the quality and quantity of livestock, ensuring healthier and more productive animals.
- Feeding and Nutrition:
Ranchers use scientifically formulated diets to optimize the growth and health of the animals, ensuring they are provided with balanced nutrients.
- Animal Health Management:
Vaccinations, medications, and disease control methods are implemented to maintain the health of the animals.
- Pasture Management:
Grazing patterns are managed to avoid overgrazing and to maintain the fertility of the land. This scientific method ensures the sustainable production of livestock while maintaining the health of the land.
In conclusion, ranching is based on scientific principles that ensure maximum productivity, sustainability, and the well-being of both the animals and the environment.

State highways are constructed and maintained by state governments and serve as major roads within a state.
Option A: Refers more to national highways, which facilitate inter-state connectivity.
Option B: Such connections are typically handled by national highways or expressways, not specifically by state highways.
Option C: Correct. State highways connect the capital of a state to its various district headquarters and important towns within the state.
Option D: This is again a function of national highways. So, the correct answer is (C): To connect state capitals with district headquarters.

A trans-continental railway is one that spans an entire continent. The railway between San Francisco (West Coast) and New York (East Coast) in the United States is a classic example of a trans-continental railway line.
Option A: Yokohama and Vancouver are in different continents and separated by the Pacific Ocean — not connected by rail.
Option B: Auckland and Honolulu are also on separate islands, making rail connection impossible.
Option C: Correct — San Francisco and New York are connected by one of the world's earliest and most famous trans-continental railways.
Option D: London and Aden are not on the same continent and have no rail connection. So, the correct answer is (C): Between San Francisco and New York.

A mixed economy refers to an economic system that combines elements of both capitalism and socialism. In a mixed economy, industries are categorized into three main sectors: public, private, and joint. These sectors play an essential role in the functioning of the economy by balancing government control and private enterprise.
- Public Sector:
The public sector consists of industries and enterprises owned and operated by the government. The government controls industries related to defense, infrastructure, education, healthcare, and natural resources to ensure equitable distribution and public welfare. Examples include public utilities, railways, and postal services.
- Private Sector:
The private sector is made up of industries and businesses owned and operated by private individuals or corporations. These industries focus on profit-making and competition in the market. Examples include retail businesses, technology companies, and manufacturing firms.
- Joint Sector:
The joint sector refers to industries where both the government and private individuals or organizations share ownership and management. This sector combines the benefits of both public and private sectors, where the government provides resources and regulatory oversight, while private businesses contribute entrepreneurial expertise. Examples include joint ventures in areas like energy, telecommunications, and infrastructure.
In a mixed economy, the balance between these sectors allows for the efficient allocation of resources while addressing social needs and promoting economic growth.

The practice of gathering generally involves collecting wild resources, such as fruits, nuts, and herbs. The statements are analyzed as follows: - I. Generally gathering is practised in regions with harsh climatic conditions: This is true because gathering is often practiced in areas where agricultural activities are difficult, due to climate or terrain, such as in tropical forests or Arctic regions.
- II. In modern times, some gathering is market-oriented: This is also correct. In some regions, gathering has become a market-oriented activity, where people collect wild products like medicinal herbs, wild fruits, and mushrooms to sell in markets.
- III. Denmark is a classical example of gathering activities: This statement is incorrect. Denmark is not typically known for gathering activities as it is a highly developed country with a focus on agriculture and industrialization.
- IV. Gathering is practised mostly by primitive societies: This is correct. Traditionally, gathering was primarily practiced by hunter-gatherer societies, particularly before the advent of agriculture. Thus, the correct option is (A), as statements I, II, and IV are correct.

The Panama Canal is a key waterway that connects the Atlantic Ocean to the Pacific Ocean through the Isthmus of Panama. It allows ships to save the long and dangerous trip around the southern tip of South America. - (A) Between Yokohama and Vancouver: This route does not use the Panama Canal.
- (B) Between Auckland and Honolulu: This route does not involve the Panama Canal.
- (C) Between San Francisco and New York: This route does indeed pass through the Panama Canal as it connects the west and east coasts of the United States.
- (D) Between London and Aden: This route does not pass through the Panama Canal. Thus, the correct answer is (C), as the Panama Canal is used for shipping between the east and west coasts of the United States, including the route from San Francisco to New York.

The assertion states that industries based on bulky, cheap, and weight-losing materials are located close to the raw materials. This is correct because such industries, like the cement industry, steel industry, and paper mills, need raw materials like limestone, coal, and timber, which are heavy and lose weight during processing. To minimize transportation costs, they are typically located near the source of these raw materials.
The reason for this proximity is to reduce transportation costs. When raw materials are bulky and weight-losing, it is essential for industries to be located close to the sources to prevent high transportation costs that would otherwise make the products expensive. Hence, the reason (R) correctly explains assertion (A).
Therefore, both (A) and (R) are true, and (R) is the correct explanation of (A).

Wholesale trading refers to the buying and selling of goods in large quantities, typically between producers and retailers or between merchants. It is not directly concerned with individual consumers. Instead, it involves intermediary merchants and supply houses that manage bulk distribution.
Option (C) correctly describes this nature of wholesale trading. The other options confuse wholesale with retail or informal trade (like street vending), which are different concepts.

India is one of the most linguistically diverse countries in the world. The Constitution of India recognizes this diversity and reflects it in various domains of public life.
Scheduled Languages: India has 22 scheduled languages under the Eighth Schedule of the Constitution, including Hindi, Bengali, Telugu, Marathi, Tamil, and Urdu.
Hundreds of Dialects: In addition to the scheduled languages, India has over 120 major languages and 1,600 dialects spoken across different regions.
State Formation on Linguistic Basis: Many Indian states, such as Andhra Pradesh, Maharashtra, Gujarat, and Punjab, were reorganised based on linguistic identity.
Medium of Education and Communication: Regional languages are used in schools, newspapers, and governance, ensuring preservation and promotion of linguistic heritage. Thus, India truly reflects unity in diversity through its vast range of languages.

Step 1: Understand the concept of agribusiness.
Agribusiness refers to commercial farming on an industrial scale, involving large-scale production, processing, and distribution of agricultural products. It is a highly integrated system that includes inputs, production, processing, and marketing.
Step 2: Analyze each statement about agribusiness.

• Statement I: "It is a commercial farming on an industrial scale." - Correct.} Agribusiness is indeed commercial farming conducted on a large, industrial scale with significant capital investment.
• Statement II: "Its raw materials are received from forests." - Incorrect.} Agribusiness primarily deals with agricultural crops and livestock, not forest products. Forest-based industries fall under a different category (forestry).
• Statement III: "It is highly structured, mechanised and large in size." - Correct.} Agribusiness operations are characterized by high levels of organization, mechanization, and large-scale operations.
• Statement IV: "Its example is tea plantation." - Correct.} Tea plantations are classic examples of agribusiness, involving large-scale commercial cultivation, processing, and marketing.

Step 3: Identify which statements are correct.
Correct statements: I, III, and IV
Incorrect statement: II
Step 4: Analysis of each option.

• (C) Only I, II and III are correct: Correct.} This option correctly identifies I, III, and IV as correct statements, and excludes II.
• (D) Only I, II, III and IV are correct: Incorrect. This includes statement II, which is false.

Final Answer:} (C) Only I, II and III are correct.

Concept: Labour intensity in agriculture depends on farm size, level of mechanisation, and purpose of production. Large-scale mechanised farming generally requires less manual labour.
Step 1: {\color{red}Understanding least labour-intensive farming.
Least labour-intensive methods use large machines and fewer workers per unit of land.
Step 2: {\color{red}Evaluate the options.}

• Plantation agriculture:
  Requires a large workforce for planting, harvesting, and processing.
• Subsistence agriculture:
  Highly labour-intensive due to traditional tools and manual work.
• Extensive commercial cultivation:
  Practised on large farms using heavy mechanisation (e.g., wheat farming in prairies).
  Requires minimal labour per unit area.
• Market gardening:
  Intensive farming with high labour input for perishable crops.

Step 3: {\color{red}Conclusion.
Extensive commercial cultivation uses mechanisation and large landholdings, making it the least labour-intensive method.

Concept: Livestock rearing can be broadly classified into commercial livestock farming and nomadic herding. The former is modern and market-oriented, while the latter is traditional and subsistence-based. Commercial Livestock Rearing:

• Well Organised Farming:
  Practised on large farms with planned breeding, feeding, and veterinary care.
• Capital Intensive:
  Requires heavy investment in machinery, fodder, refrigeration, and transport.
• Use of Technology:
  Modern techniques like artificial insemination, scientific breeding, and mechanised dairying are common.
• Market-Oriented Production:
  Products like meat, milk, and wool are produced mainly for commercial sale.
• Regions:
  Common in developed countries like USA, Australia, and New Zealand.

Comparison with Nomadic Herding:

• Traditional and Subsistence-Based:
  Nomadic herding is practised by pastoral communities for survival rather than profit.
• Low Capital Requirement:
  Minimal investment and dependence on natural grazing lands.
• Seasonal Migration:
  Herds move in search of pasture and water.
• Limited Technology:
  Traditional knowledge and simple tools are used.

Conclusion:
Commercial livestock rearing is organised, capital-intensive, and market-driven, whereas nomadic herding is traditional, mobile, and subsistence-oriented.

Concept: Early human societies lived as hunter-gatherers and had a close relationship with nature. Their survival depended directly on the availability of natural resources in their surroundings. Explanation with Reference to Hunting and Gathering:

• Dependence on Natural Resources:
  Early humans relied on forests, rivers, and grasslands for food, water, and shelter.
• Hunting Animals:
  They hunted wild animals for meat, skins, and bones using primitive tools made of stone and wood.
• Gathering Edible Plants:
  Fruits, roots, nuts, seeds, and berries were collected from the wild for daily consumption.
• Nomadic Lifestyle:
  Since food sources were seasonal and limited, people moved from place to place in search of resources.
• Minimal Environmental Modification:
  Early humans had limited technology and did not significantly alter the environment.
• Knowledge of Nature:
  They developed deep knowledge of animal behaviour, plant types, and seasonal changes.

Conclusion:
Thus, hunting and gathering societies depended entirely on their immediate environment for sustenance, reflecting a strong human–nature relationship.

Concept: Labour-intensive farming refers to agricultural systems that require a large amount of human labour relative to land size and capital use. Such farming is usually practiced in developing regions with limited mechanisation.
Step 1:Understanding labour-intensive farming.
Labour-intensive agriculture depends more on manual work than machines. It is commonly found in areas with high population density and small landholdings.
Step 2:Evaluating the options.

• Horticulture:
  Requires skill but not always the most labour-intensive compared to traditional farming.
• Subsistence Agriculture:
  Practised mainly by small farmers using traditional tools and family labour.
  Minimal mechanisation makes it highly labour intensive.
• Co-operative Farming:
  Organised farming with shared resources; may involve machinery, reducing labour intensity.
• Collective Farming:
  Usually large-scale and mechanised (e.g., socialist economies), hence less labour intensive.

Step 3:Conclusion.
Subsistence agriculture relies heavily on manual labour and traditional techniques, making it the most labour-intensive type.
