Explanation: This conclusion can be drawn from a number of factors, including:
* The colonists were not experienced in farming or hunting, and they relied heavily on supplies from England.
* The climate was harsh, and the colonists were not prepared for the extreme temperatures or the lack of food.
* The colonists were constantly under threat from Native American attacks.
All of these factors contributed to the failure of Roanoke. The colonists were simply not equipped to survive in the New World, and they were eventually abandoned by their English sponsors.
