Question

what was the biggest impact of trans - saharan trade routes on african kingdoms? they were used only for military purposes in conquering new territory. they isolated african kingdoms from external cultural influences. they focused solely on the trade of gold and salt, with little impact on knowledge exchange. they facilitated the exchange of ideas and technologies across regions.

Explanation:

The Trans - Saharan trade routes were not just for military use (so the first option is wrong). They did not isolate African kingdoms; instead, they connected different regions. Trade on these routes was not only about gold and salt; it also led to the exchange of ideas, religions (like Islam), technologies, and cultural elements. For example, Islamic scholars traveled along these routes, bringing new knowledge and educational systems. So the option about facilitating the exchange of ideas and technologies is correct.

Answer:

They facilitated the exchange of ideas and technologies across regions.
