Explain the weakness of non-documentary Sources of African history.

The weaknesses of non-documentary sources of African history include:

• Loss of Information: Information passed orally can be lost permanently if the informant dies, especially since it is not written down.
• Inaccurate Dates: Dates derived from oral traditions may be imprecise or inaccurate, making it difficult to establish a reliable timeline.
• Time-Consuming: Methods like archaeology require extensive processes and time to yield final results.
• Expensive: Archaeological excavations are costly, requiring expensive equipment and resources.
• Vulnerability to Natural Disasters: Archaeological sites and artifacts can be damaged or lost due to natural disasters, which can also pose risks to human life.
