XDF蓝皮书198

Demographers doing research for an international economics newsletter claim that the average per capita income in the country of Kuptala is substantially lower than that in the country of Bahlton. They also claim, however, that whereas poverty is relatively rare in Kuptala, over half the population of Bahlton lives in extreme poverty. At least one of the demographers' claims must, therefore, be wrong.

The argument above is most vulnerable to which of the following criticisms?

B. It treats the vague term"poverty" as though it had a precise and universally accepted meaning.

E. It does not consider the possibility that incomes in Kuptala, unlike those in Bahlton, might all be very close to the country's average per capita income.

B选项说贫穷是个模糊含义的词，那么如果两个地方对贫穷的定义不一样，就有可能造成B地贫穷的人口更多啊。为什么错了呢？

E选项之所以对是不是因为K 地收入水平都差不多，所以贫富差距不大，所以贫穷的人少？
