Concept:Africa’s high poverty rate is particularly driven by widespread unemployment among its largest population group.
Explanation:Africa has a very young population, and the majority are of working age.
When most of these people cannot find jobs, they earn little or no income.
This lack of income pushes many households below the poverty line.
Corruption and insecurity are significant, but they are not the main or most direct cause.
The word “particularly” in the question points to the most immediate factor.
Thus, the unemployment of the largest part of the population explains the rise in poverty best.
Answer:A. The largest proportion of Africa’s populations are unemployed.
