Why is everyone stressing this week?

cause i just had to take a math test plus I have an essay to write and I have know idea how but i sent in a rough draft but he said it needs to be 3 pages longer but I don't really know how to write an essay like that but the rough draft i had help on sooo yea

Explanation:

When people think about the first people in America, they might think of Christopher Columbus or the European colonists; when, in fact, the first people were the Indians. The Cherokee Indians had lived in the lands of what is now the United States for thousands of years before any colonists had ventured over. Little did they know that the new nation that was going to be forming around them, would severely affect the lives of their descendents.

Life before the Trail of Tears but after the arrival of the new Americans was more or less simple for the Cherokees. They spend time hunting and fishing. Some of them even worked on plantations and even owned their own slaves, in an effort to accommodate some of the American ways of living.

this is the rough draft but it needs more if you know anyone who can help it's much appreciated :)
