Read this excerpt from a passage about Easter Island, an island in the South Pacific that once supported a complex civilization. Which type of evidence would support the author's thesis?
Historians and scientists agree that the landscape of Easter Island was much different when the first islanders arrived from Polynesia in 800. The island was covered in lush forests of palm trees and was inhabited by large populations of birds. Less than 600 years later, the island was a barren wasteland of grasses. The ecosystem on Easter Island collapsed as a result of the reckless use of natural resources by islanders, destroying the island civilization and making the island a challenging environment to live in.
A.) A journal written by one of the civilization's chiefs describing how trees on the island died out after people cut down too many for wood
B.) Photographs of the many grasslands that cover Easter Island today
C.) Several articles written by different historians describing how people from Polynesia first journeyed to Easter Island by boat more than 1,000 years ago
D.) Interviews with people currently living on the island who enjoy bird-watching
