Final answer:
The Agricultural location model is the Von Thünen Model, which includes von Thünen's rings of agricultural production around a central market and The Isolated State concept, making the answer 3) Both A and B.
Step-by-step explanation:
The Agricultural location model refers to the theory developed by the 19th-century German economist Johann Heinrich von Thünen, known as the Von Thünen Model. This model predicts a series of concentric rings surrounding a central market, each dedicated to a different type of agricultural production, based on the transportation costs and perishability of the crops. The land closest to the market would be used for more perishable and expensive-to-transport crops like dairy, while land farther away would be used for less perishable crops like grain.
Although technological advancements such as refrigeration and rapid transportation have altered some aspects of agriculture, the model's basic principles regarding the importance of transportation costs in farm location decisions still hold true. This can be seen in modern agricultural patterns, such as market gardening farms located within a day's drive of a city's produce warehouse, and large-scale grain farms situated farther away from urban centers, reflecting the core tenets of Von Thünen's theory.
Answer to the Student's Question
The correct answer to the question is 3) Both A and B, as the Agricultural location model encompasses both von Thünen's idea of different farming types organized in rings around a city (von Thünen's rings) and the hypothetical construct of an isolated state with a central market to which these rings pertain (The Isolated State).
