In the new world build the relationship between east and west africa. a. a shared water supply c. arranged marriages b. advanced transportation systems d. trade

d. Trade is the answer. East and West Africa learned more about each other through trading. Sharing water supply would cause conflict, arranged marriages would require a bond beforehand to marry one of your people to another's people. Advanced transportation systems would still not create a relationship. Trade is the logical answer, and I had this question, I said d, and it was right.

answer; i believe the answer is 80%, plz check first good luck;
