The image best serves as evidence that many native americans groups had developed farming techniques

You did not put the image to which the question is referring, but considering that some Native Americans dominated advanced agricultural techniques, we can say that the image can serve as evidence.

Explanation:

There are reports and evidence that some Native American tribes in fact dominated agricultural techniques that were very advanced for their time. These tribes were located mainly in the southern region of the USA, in Mexico and in the Andean region of southern Amperida.

These Native Americans had good agricultural production because they mastered irrigation techniques, sloping terraces, fertilization, crop rotation and use of windbreaks. They even mastered very efficient storage techniques and guaranteed a good food supply.

an economic reason that the south needed a reconstruction plan is that plantations, factories, and other businesses were destroyed during the war.

b.

one company controls all the means of production of a product.
