which would have the least impact on mesopotamian long distance trade systems? a sail b iron c roads d wheeled carts
Answer
Brief Explanations:
- Sail: Used in river and sea trade, facilitating movement of goods over water.
- Iron: As a valuable resource, it was traded and used in tools/weapons, impacting trade.
- Roads: Enabled over - land trade, connecting different regions.
- Wheeled carts: Used on land for transporting goods, but Mesopotamia's long - distance trade was more river - based (Tigris and Euphrates). While they had some use, compared to the others (sail for water, iron as a trade item, roads for over - land), their impact on long - distance (especially considering the riverine nature of much of Mesopotamian trade) was relatively less.

D. wheeled carts
