Explanation:

1. You should right the "Gold & Salt Trade". Many items were traded between North Africa and West Africa, but the two goods that were most in demand were gold and salt. The North Africans wanted gold, which came from the forest region south of Ghana. The people in the forests wanted salt, which came from the Sahara.

2. Ghana and Mali, At first Taghaza had been controlled by the Saharan nomads, but in the early 14th century the rulers of Mali managed to maintain some control over the routes leading these mines from the south.

3. Niger river

4. Muslim Traders, Following the conquest of North Africa by Muslim Arabs in the 7th century CE, Islam spread throughout West Africa via merchants, traders, scholars, and missionaries, that is largely through peaceful means whereby African rulers either tolerated the religion or converted to it themselves.

5. Timbutku.

6. Sahara Desert.

7. Islam.

i beleive a. is the only possible answer

the captain of a steam ship naturally chooses the shortest route to his destination. since a sailing ship is usually pushed by winds and currents, its captain must find a route where the wind will probably blow in the right direction. tacking, i.e. using contrary wind to pull (sic) the sails, was always possible but wasted time because of the zigzagging required, and this would significantly delay long voyages. the early european explorers were not only looking for new lands. they also had to discover the pattern of winds and currents that would carry them where they wanted to go. during the age of sail winds and currents determined trade routes and therefore influenced european imperialism and modern political geography. for an outline to the main wind systems see global wind patterns.

pilotage or cabotage, in one sense, is the art of sailing along the coast using known landmarks. navigation, in one sense, is the art of sailing long distances out of sight of land.[1] although the polynesians were able to sail the pacific (with great difficulty) and people regularly sailed north and south across the mediterranean, before the time of columbus nearly all sailing was coastal pilotage
