Brief Explanations:

During the colonial period, African colonies were often set up to produce specific cash crops for the colonizing powers. This led to economies overly reliant on one or two crops. Industrial development was limited as colonies were exploited for raw materials. A strong middle class was not a feature as economic structures were skewed. Diverse farmlands were not the basis of economic dependence; rather, monoculture or near - monoculture of certain crops (like cocoa, coffee) was.

Answer:

one or two crops.
