The location of market gardening near large cities is best explained by

Step 1: Analyze the question The question asks why market gardening (growing vegetables, fruits and flowers for sale) is located close to large cities. It is asking about the main reason for the location.

Step 2: Explain the concept Market gardening (truck farming) is the intensive production of vegetables, fruits and flowers, mostly for urban consumers. These products, such as tomatoes, lettuce, spinach, okra and fresh pepper, are highly perishable. They spoil quickly, are bulky, and can be damaged during long journeys. This is why they are grown close to the markets where they will be sold.

This idea comes from the von Thünen model of agricultural location. Perishable, bulky products with high transport costs and a short shelf life are produced nearest to the urban market.

Step 3: Evaluate each option

• A. Availability of power: Power helps, but it does not decide where market gardens are sited.
• B. Fertile soil: Good soil helps farming anywhere, and market gardeners can improve soil with manure and fertilizer. It does not explain why farms cluster near cities.
• C. Perishability of products: Fresh vegetables spoil quickly, so they must reach consumers fast and fresh. This is the key reason for locating near large cities. ✔
• D. Efficient transportation: Good transport helps, but if transport were the main factor, the farms could be located far away. Nearness is needed because the produce is perishable, so transport is a supporting factor and not the best explanation.

Step 4: Answer

Exam tip: When you see "near large cities" in a question on market gardening or dairy farming, think perishable + bulky + nearness to market. Remember it as: "Fresh and fast, so farm close."
