Answer:
The longevity of the agricultural product is the most important factor when it comes to the closeness of the agricultural activity to the central market.
Explanation:
When it comes to agricultural activities, it is very important to take into consideration the type of product that is produced and its characteristics, so that the distance from the central market is adequate. This comes from the fact that not all agricultural products have the same reslience or longevity, and also they differ in how good they can bear transportation, changing temperature, etc.
Agricultural products that have short longevity and are not suitable for long-distance transportation should always be as close as possible to the central market as if they are not there will be big losses which doesn't do a favor to anyone. On the other hand, the agricultural products that have long longevity and are easy and not problematic for long-distance transportation can be produced far away from the central market without any problem.
