What makes more sense out of all of them is number 2. Engage
In the passages, the author gives a few details that develop the idea that establishing a colony at Roanoke was going to be difficult because of the Native Americans. The author says, "not all relations between the colonists and the Native Americans were friendly." He expands on this when he states, "some Native Americans were still angry about the colonists' presence and threatened to do battle." The Native Americans who did not want the English colony at Roanoke made it difficult to establish a colony.
Most authors make typos like the one mentioned in order to give you a clear image as to how the narrator tells the story and in what mood the theme is set.
Hope this helps!
