JAMB - History (2019 - No. 1)
Increase in the number of people living below the poverty line in Africa is particularly because
The largest proportion of Africa's populations are unemployed
Of the prevalence of corruption
Of the problem of insecurity scaring away investors
A vast majority of its populants have chosen to be unproductive
설명
It is largely and logically smart to trace Africa's poverty increase to the widespread unemployment rate of the youth - the largest proportion of the African population. N.B: as much as almost all of the options are right, the emphasis in the question is on 'particularly'.
