Final answer:
The tribal armed resistance to colonial powers in Africa failed to repel European invasions due to a lack of advanced weaponry, unity among tribal groups, knowledge of European tactics, and overwhelming European military power. All options are correct.
Step-by-step explanation:
The tribal armed resistance to colonial powers in Africa failed to repel European invasions of the continent due to a combination of factors. First, there was a lack of advanced weaponry among the tribal groups, which put them at a disadvantage against the better-equipped European forces. Secondly, there was a lack of unity among tribal groups, which made it difficult to mount a cohesive resistance against the Europeans. Thirdly, the limited knowledge of European tactics made it challenging for the tribal groups to effectively counter the European invasions. Finally, the overwhelming military power of the European forces, including their superior weapons and technology, was a significant factor in the failure of tribal armed resistance.
