Why do most east africans make their living by farming and herding?

What does your book say about the reasons?

it doesnt say i am doing q chapter review and the question im on is a critical thinking question so its not in the book

The critical thinking questions is asking you to review what you know about East Africa, put it all together, and then answer the question.

Think about the available jobs, industries, customs, and the fertility of the land.

thank you

You're welcome.

one more question what problems have resulted in part from the boundary lines drawn by european powers and how might the countries of east africa overcome theseproblems?

The European powers established national boundary lines to suit their needs -- not the needs and wants of the East African people. Ethnic groups were split and combined with no consideration for the people involved.

How do YOU think these countries can overcome these problems?
