Final answer:
Cactus Hill illustrates that archaeological interpretations are complex and must be approached with caution due to the incomplete and fragmentary nature of evidence, which often leads to the need for revisions as new findings are made.
Step-by-step explanation:
The existence of archaeological sites like Cactus Hill highlights the inherent challenges that archaeologists face when forming theories about past civilizations. The correct answer to the student's question is D. Cactus Hill shows that archaeological interpretations require careful analysis due to incomplete evidence.
Despite advances in archaeological techniques, such as laboratory analysis and the use of GPS, there are limits to our understanding due to the fragmentary nature of the archaeological record. Sites like Göbekli Tepe reveal that archaeologists must be open to revising their interpretations as new evidence comes to light, often reshaping our understanding of ancient societies.
Further complicating matters, contemporary issues affect archaeological practice, necessitating respect for local communities and their heritage, as seen in the mixing of oral traditions with scientific methods.
