The most accurate statement about the experience of immigrants in the Chesapeake colonies during the seventeenth century is:
"The danger posed to new immigrants in the Chesapeake colonies persisted throughout the seventeenth century, especially during the late summer."
This statement aligns closely with the excerpt, which notes the high mortality rates among new arrivals and emphasizes that the Chesapeake colonies were considered dangerous to immigrants well into the late seventeenth century, particularly during specific times of the year.
