-The Duwamish people were the first people of Seattle. They lived close to the shores of lakes and rivers, and they consider themselves "water people" they had a long culture of fishing and the newcomers were able to learn from them.
- They also had cultivated lands with which they helped the settlers sharing their food and helping them to farm their own food.
- They built houses and thought the newcomers how to create boards from cedar, and their techniques for creating shelter.
- Duwamish people helped the non-Native inhabitants of this land in the "Puget Sound War". They participated in the war, which was their main help, but Duwamish weapons were also used in this confrontation by the settlers.
Almost all options are correct except for the last one: "They taught the settlers to trade."
Settlers already knew how to trade, even though the help of the Duwamish people was also very important, helping them cross rivers and lakes creating trading routes, helping hunting and teaching them about furs and wood types, these became an important trade quickly.
