Step-by-step explanation:
The text "uncontacted peoples" in the context provided from IXL BYP seems to refer to indigenous groups that have not been in contact with modern civilization, particularly during the context of the pre-contact era in the Americas which is detailed in the shared resource. The reference to islands near the Isle of St. John being uninhabited implies a discussion about the populations who lived in the Americas before European contact. The excerpt from LibreTexts™ speaks to the presence (or absence) of human populations in certain areas during the period between 1000 and 1492 CE, a time when different cultures existed in the Americas in isolation from the European and other continents.
