Answer:
C. Europeans established their first settlements in 1492. unsuccessful
Explanation:
In addition, many of the first attempts at settlement north of the Caribbean failed. Roanoke, Ajacan, Fort Caroline, Sable Island, Charlesfort, Pensacola, San Miguel de Gualdape, Charlesbourg-Royal, France-Roy—all were short-lived settlements in the 1500s. A hurricane destroyed the first Pensacola settlement. Frigid winters and scurvy claimed several settlements; starving settlers abandoned others. Indians laid siege to settlements or attacked them outright. Rebellion by brutalized soldiers or starved African slaves ended two colonies. Settlers were left to their own resources when the founders left for provisions (or for good). In most cases a few surviving settlers made it back to Europe, but in one famous case—the "Lost Colony" of Roanoke in what is now North Carolina—the settlers disappeared with little trace, their fate still undetermined. Most share the dooming factors of poor planning and unrealistic appraisals of the North American environment. Simply put, settling this continent was not going to be easy.
