c. its capital, cairo, was on the bend of the niger river.
d. most of its people continued to worship the old songhai gods.
e. the muslim empire of mali conquered large stretches of songhai.

The correct answer is option C - Its capital, Cairo, was on the bend of the Niger River.

The Shongai Empire was located in the western part of upper Africa, on the middle reaches of the Niger River. It started as a fishing and trading center on the Niger River, in a place called GAO. Then, it extended west to the Atlantic coast.

Songhai people were influenced by Islam. They were ruled by Mali and forced to kneel before their kings.

In 1591 Morocco invaded Songhai using firearms, and finally, West Africa´s most powerful Empire was defeated.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
