The correct answer to this open question is the following.
Here is my short paragraph.
The short- and long-term effects of European imperialism in Africa as a result of the scramble for Africa were the following.
The Scramble for Africa refers to how European nations wanted the biggest and richest colonies in Africa.
Shorte term: What Europeans really wanted was to exploit the many raw materials and natural resources that were abundant in Africa, in order to make big profits.
Long-term: these African nations never learned how to govern themselves after the Europeans granted their independence. That is why these nations have a corrupt and inefficient government even today.
After the Berlin Conference of 1844-1845, European superpowers agreed on regulating the split of the African Continent. These European superpowers such as France, Germany, Great Britain, Spain, and Portugal split the African territory, displaced people, and created new borders in order to colonize the territories.
