What did the travelers' stories provide alongside the map illustrations in al-Idrisi's work?

• A. Weather patterns of the lands
• B. Economic data about the regions
• C. Names of the travelers only
• D. Context and additional information about the lands they visited

Answer: (D)

The main idea being tested is that travelers’ stories in al-Idrisi’s work provide context and extra information about the lands visited. The map shows where places are, but the accompanying narratives describe what those places are like— details about cities, routes, landscapes, climate, cultures, goods, and political conditions—so the atlas communicates a fuller picture of the world. This combination helps rulers and travelers understand not just coordinates, but what to expect when moving through or trading with different regions. Weather patterns or economic data aren’t the primary purpose of these narratives, and simply naming the travelers wouldn’t convey the lands themselves.
