متن زیر رابخوانید و به سوالات داده شده هر قسمت پاسخ دهید.When early humans hunted and collected food, they could not control their environment. They could live in their environment like other animals. When humans learned to make fire, however, they became skillful at changing their environment. To provide themselves with fuel, they cut trees and made fires. Parts of forests were changed to lands to increase the growth of grass and to provide a greater area for the animals that humans ate as their food. This improvement ended in farming and also keeping animals as sources of human food. Fire also provided the means for cooking plants which were not used before. After meeting the simple need for food, early humans began to follow other goals such as founding the cities and living in larger groups.
