4. Von Thünen Model

What does the Von Thünen Model explain?

A. Urban development
B. Industrial location
C. Agricultural land use patterns
D. Climate zones

Answer: C. Agricultural land use patterns

Rationale:
The Von Thünen Model explains how agricultural land use varies based on distance from a central market. It suggests that crops requiring frequent transport or that are perishable are grown closer to the market, while less perishable goods are produced farther away. Transportation costs and land value influence these patterns. Although the model assumes a simplified environment, it helps explain real-world agricultural distribution and economic decision-making.

5. Intensive vs Extensive Farming

Which best describes intensive agriculture?

A. Large land, low labor
B. High labor and high yield per area
C. Low production
D. No technology

Answer: B. High labor and high yield per area

Rationale:
Intensive agriculture uses significant labor and inputs such as fertilizers and irrigation to produce high yields on small plots of land. It is common in densely populated regions where land is limited. Farmers maximize output from each unit of land. In contrast, extensive agriculture uses large areas with lower inputs and yields per unit area. Intensive farming is often associated with subsistence or small-scale commercial systems.

6. Plantation Agriculture

Plantation agriculture is best described as:

A. Small-scale subsistence farming
B. Large-scale commercial farming in tropical regions
C. Urban farming
D. Government farming

Answer: B

Rationale:
Plantation agriculture involves large-scale production of cash crops like coffee, sugar, or bananas, typically in tropical regions. These farms are often owned by corporations and rely on cheap labor. Products are usually exported to developed countries. This system reflects global economic inequalities and historical colonial patterns. It is a major part of global agriculture and trade.

7. Green Revolution

What was a major effect of the Green Revolution?

A. Decreased food production
B. Increased crop yields
C. Reduced technology use
D. Less irrigation

Answer: B

Rationale:
The Green Revolution introduced high-yield crop varieties, fertilizers, pesticides, and improved irrigation techniques, significantly increasing agricultural productivity. While it helped reduce hunger in many regions, it also led to environmental issues and increased reliance on chemical inputs. It transformed agriculture in developing countries and remains a key concept in global food production.

8. Crop Rotation

What is the purpose of crop rotation?

A. Increase pests
B. Maintain soil fertility
C. Reduce production
D. Increase cost

Answer: B

Rationale:
Crop rotation involves alternating crops in the same field to maintain soil nutrients and reduce pests and diseases. Different crops use and replenish nutrients differently, improving soil health. This sustainable practice reduces the need for chemical fertilizers and enhances long-term productivity.

---

9. Monocropping

Monocropping refers to:

A. Growing multiple crops
B. Growing one crop repeatedly
C. Raising animals only
D. Mixed farming

Answer: B

Rationale:
Monocropping is the practice of growing a single crop over a large area year after year. While it increases efficiency and simplifies farming, it can lead to soil depletion and increased vulnerability to pests and disease. It is common in commercial agriculture.

---

10. Agribusiness

Agribusiness refers to:

A. Small farms
B. Farming for survival
C. Large-scale farming businesses
D. Government farming

Answer: C

Rationale:
Agribusiness includes all activities related to large-scale agricultural production, processing, and distribution. It combines farming with business operations and is a major part of modern agriculture in developed countries.
