Final answer:
The strongest evidence supporting the idea of a historical basis for the Trojan War comes from archaeological find dating to around 1180 B.C. with charred debris and skeletons, directly suggesting a significant conflict.
Step-by-step explanation:
The best piece of evidence from the article that supports the idea that the Trojan War, or a similar war, really happened is (D) Recent excavations have shown an inhabited area 10 times the size of the citadel. A layer of the excavation, dating to about 1180 B.C., reveals charred debris and scattered skeletons. This evidence directly indicates a significant conflict that resulted in widespread damage and loss of life, which could correlate with the war described by Homer in the Iliad.
Options (A), (B), and (C) provide supportive context but do not offer definitive proof of a historic event comparable to the Trojan War. Option (A) merely establishes the location of Troy, while options (B) and (C) recount literary accounts of what occurred after the supposed war. These narratives, although valuable, are less persuasive without the tangible archaeological evidence provided in option (D).
