Final answer:
The question seeks a safe docking site for ships among four cities. Alexandria, Egypt, and London, England, emerge as the best options due to their historical significance as port cities, whereas Rome and Richmond are not directly on the sea.
Step-by-step explanation:
The question asks which of the following sites would provide a safe place for ships to dock, with the options being Richmond, VA; Alexandria, Egypt; London, England; and Rome, Italy. To evaluate these options, consider the geographical location and the historical context of each city. Rome, for example, is not directly on the sea; it is inland on the Tiber River. Similarly, Richmond, VA is up the James River, which, while navigable, does not serve as a major location for ships to dock in comparison to other options. Alexandria, Egypt, on the other hand, has a significant historical role as a port city on the Mediterranean Sea. London, England, also has a long history as an important port city on the Thames River. Therefore, the best options for a safe place for ships to dock would be either Alexandria or London.
