The vicious circle of poverty in the poorest DVCs can also be expressed as,

A) "The rich get richer, while the poor get poorer."
B) "Fate dealt the poor nations a bad hand."
C) "The poor nations stay poor because they are poor."
D) "Historical developments have oppressed the poor nations' incomes."

The phrase "The poor nations stay poor because they are poor" best summarizes the vicious circle of poverty in the poorest DVCs. This is because poverty leads to poor health and education outcomes, which in turn lead to limited opportunities and low productivity. Low productivity leads to low income levels, which perpetuate poverty and maintain the cycle. This cycle can be difficult to break without targeted interventions to address the root causes of poverty.
