Final Answer:
The supporting evidence used in the article includes Option 1 (Some Lumbee Indians have light complexions and blue eyes), Option 2 (Scientists plan to do DNA testing on the Lumbee Indians to determine whether they are related to the colonists), Option 3 (It seems likely that some, if not all, of the colonists went to live among the native peoples of the Outer Banks), and Option 4 (The word Croatoan was carved on a tree).
Step-by-step explanation:
The author employs a multifaceted approach to bolster their argument. Firstly, Option 1 provides observational evidence, pointing out the physical characteristics of some Lumbee Indians, such as light complexions and blue eyes, suggesting potential connections to the colonists.
Option 2 introduces a scientific dimension, indicating plans for DNA testing to establish a genetic link between the Lumbee Indians and the colonists, adding a layer of empirical verification.
Furthermore, Option 3 introduces a historical plausibility, suggesting the likelihood that some or all of the colonists might have integrated with the native peoples of the Outer Banks, contributing to the narrative. Lastly, Option 4 introduces an archaeological element, citing the carving of the word "Croatoan" on a tree, which could be seen as a clue or marker potentially linking the colonists to the Lumbee Indians.
By incorporating diverse types of evidence, the author strengthens the overall credibility and persuasiveness of their argument, appealing to both scientific and historical reasoning, as well as tangible, observable phenomena.
