Question

how did africa’s role in global trade change after europeans built fortified posts on the atlantic coast in the 1400s? choose 1 answer: a falling interest in asian goods closed indian ocean markets and ended coastal trade. b europeans replaced african control over trade in all regions by the 1400s. c bans on camel caravans ended the gold - salt exchange that had enriched west africa. d demand for labor in the americas led to some ports trading enslaved people.

Explanation:

• Option A: Interest in Asian goods didn't fall to close Indian Ocean markets; coastal trade continued, so A is wrong.
• Option B: Europeans didn't replace African control over all trade regions by the 1400s; African states still had control in many areas, so B is wrong.
• Option C: There were no bans on camel caravans ending the gold - salt trade; the gold - salt trade continued, so C is wrong.
• Option D: After Europeans built fortified posts on the Atlantic coast, the demand for labor in the Americas (from plantation economies) led to the trans - Atlantic slave trade, where some African ports traded enslaved people. This matches the change in Africa's role in global trade.

Answer:

D. Demand for labor in the Americas led to some ports trading enslaved people.
