1. Since I want to find out more about my Native American ancestors, I've decided to research my family tree.

2. I've learned to speak Navajo. As a result, I can chat online with people from the Navajo community in New Mexico.

3. As Native Americans have to use English in their daily lives, they all speak English.

4. In the late nineteenth century, the US government forced all Navajo people to live in the same place. Therefore, almost all of them live in New Mexico nowadays.
