Answer:
D
Step-by-step explanation:
The correct answer is D) Swiddens not under cultivation are used for fruit trees. Shifting cultivation, also known as slash-and-burn agriculture, involves clearing land by slashing vegetation and then burning the debris to provide the soil with nutrients. This process prepares the land for cultivation. Additionally, in shifting cultivation, a new site is designated every few years to allow previously used areas to recover and regenerate. However, the characteristic mentioned in option D is not a part of shifting cultivation. Swiddens, which are the cleared and cultivated plots of land, are not typically used for fruit trees in shifting cultivation. Instead, swiddens are used for the cultivation of crops such as corn, rice, or other food crops. Therefore, the correct answer is D) Swiddens not under cultivation are used for fruit trees.
