In Africa, roads shouldn't be classified based on their conditions,
width, surface, etc, but, as it is stated in the Highway_Tag_Africa
wiki, the main source of classification should be their importance in
the communication among towns and villages. It takes some time to
adapt when coming from mapping in developed countries.

Do your best. Most dwellings are huts in rural Africa.

Welcome to the world of imagery scarcity ;)

Many jobs in the Tasking Manager are part of a HOT activation. Every
activation is coordinated by one or two people. For example, the Ebola
activation is coordinated by Pierre Béland and Andrew Buck.
