The correct answer is D. Analysis of the cracks in the walls of Hisarlik may change conclusions about the site.
Step-by-step explanation:
The text explains the city of Troy, which is described in "The Iliad", is located in a site known as Hisarlik in Turkey. Moreover, cracks caused by an earthquake have been found in the walls of his place. This piece of evidence suggests the city might not have been destroyed by war as suggested in "The Iliad", but by an Earthquake. According to this, one conclusion a historian can draw based on this evidence is that analysis of the cracks in this place may change the conclusions about this site, especially about the destruction of the place (Option D.)
