This map shows trade routes established in the sixteenth century. Which statement BEST explains how geography affected the locations of these slave ports?
A Most ports were along the Nile River so enslaved people could be transported within Africa.
B The ports of origin and destination were on coasts, which were accessible to ships.
C The destinations were mountainous, making it nearly impossible for enslaved people to escape to freedom.
D To avoid harsh travel conditions, all slaves were brought to the southern hemisphere.
The correct answer is B: The ports of origin and destination were on coasts, which were accessible to ships.
Explanation: Geography played a crucial role in trade routes during the sixteenth century, especially in the Atlantic slave trade. Coastal ports were strategically located to allow ships to easily access and transport enslaved people. The proximity to the ocean facilitated trade and ensured that goods, including enslaved individuals, could be quickly loaded and shipped across the ocean to other regions. The inland locations, such as mountains or rivers, would have posed challenges for transport by sea.
