B??? Where is A?! Maybe B ate A which is why no one answered your question yet.
Well Kush is a type of plant, Nokia is a phone company, and Aksum is a university located in Ethiopia, I would say that all of these "peoples" were indeed very successful in their works.
The kingdom of Aksum was located around the red sea which allowed for a good water resource, there was also many mountains and forest land. Plus, they practiced the art of terracing, which allowed their crops to grow at a good rate no matter what level of the land its on, Aksum still exists today in Ethiopia.
The Kush civilization, better known as Nubia, Lived along the Nile and instead of forests like the Aksum people, they lived in desert terrain which means that farming was nearly impossible. They still managed to grow crops though, thanks to the Nile's fertile land.
Nok people are Africa's oldest known civilization and they were some of the first people to master the art of Iron. The civilization was also pretty advanced at its time which meant that it can defend itself very well compared to other tribes. They lived in modern day Nigeria, surrounded by rivers, because of the abundance of rivers, they could get food and water extremely easily compared to the other tribes, the way they died out though, still remains a mystery
