Answer:
D. The people of Middle America realized they could grow crops for a more reliable food supply.
Explanation:
Before settling down, people in the middle America relied on hunting and gathering plants as their main methods to obtain food supply.
But, this method was extremely unreliable. They had to constantly move from one area to another due to climate changes or decrease in animals population.
After settling down into villages, they started to adopt agricultural practices to obtain their food supply. This methods are way more reliable than hunting/gathering since they don't have to move and they can stock their supplies into their warehouse before winter.
