Answer:
The answer is D. Limited farmland encourages intensive farming with intercropping to produce high yields.
Explanation:
When practicing agriculture of any form, be it crop or animal agriculture, the resources used are always limited and will not be enough.
Therefore, in the scenario presented above, we see that the land to be used is limited, hence, the farmer must think of a way to maximize the use of his limited land.
The best way to do this is practice what is known as inter cropping, this strategy has the following merits:
- higher yield compared to planting just one crop.
- it serves to mitigate against risk.
- higher revenue will be generated from the sale of both crops.
Therefore it is imperative that farmers with limited land look for ways to maximize the use of the land.

In the suggest period between 200,000 and 12,000 years ago, humans were living a nomadic lifestyle. The humans of this period were hunter-gatherers, and they were constantly moving from one place to another in accordance to the food supply and climate conditions. Because of this constant movement and constant search for better hunting grounds and places where there's much bigger and more constant supply of fruits, vegetables, root plants, they managed to disperse in very big space and little by little to colonize the planet. In this period the cultivation of plants was still not taking place, and also the humans still hadn't managed to domesticate any wild animals, apart from the wolf which gave rise to the dog, but it was used for hunting, not as a food source.
