Final answer:
A timeline of Alexander the Great's reign and a map of his conquests are the most helpful text features to understand his role in spreading Greek culture.
Step-by-step explanation:
To support the central idea of a passage focusing on Alexander the Great and his influence on the spread of Greek culture, the most helpful text features would be:
- A timeline showing when Alexander the Great's power came to an end, as this would provide a chronological context for his accomplishments and the duration of his impact.
- A map showing the extent of Alexander the Great's conquests, which could help visually demonstrate how Greek culture was spread throughout the known world due to his military campaigns.
While Alexander the Great's role in spreading Islam is not historically accurate (as Islam arose centuries after Alexander's death), it is essential to choose text features that accurately represent the historical subject matter.
Annotated maps and timelines are crucial text features that enhance our understanding of historical events and the spread of cultures. A detailed map tracing Alexander's route or a timeline of his victories and governance would precisely serve these educational purposes.
