6. 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?

(A) It rejects an empirical claim about the average per capita incomes in the two countries without making any attempt to discredit that claim by offering additional economic evidence.

(B) It treats the vague term “poverty” as though it had a precise and universally accepted meaning.

(C) It overlooks the possibility that the number of people in the two countries who live in poverty could be the same even though the percentages of the two populations that live in poverty differ markedly.

(D) It fails to show that wealth and poverty have the same social significance in Kuptala as in Bahlton.（E）

(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.

能讲讲B的错误吗?谢谢!

我觉得poverty在文中没有异议阿，没有vague

一个国家人民的平均收入比另一个国家高，而贫穷的人少，说明人们都收入相差比另一个国家小，即标准差小，呵呵，所以e对

这题还是百思不得其解！

我理解的难道有问题么？

K的人均收入比B少，而K的财富很少，B的一半以上的人很富。

这两句话没有任何矛盾吧？！人均收入少，自然财富少啊！

 A  1，1，1，1，1，100，100

B  2，2，2，2，2，2，2   

如果小于2是poor   

那么B中根本没有穷人    A中有5个穷人    但是B的平均比A小很多

明白了，谢谢。我再整理一下。

K国：5 5 5            人均工资：5

B国：1 1 10 10 10     人均工资：6.x

满足题目中的条件：K比B工资低，B超过一半的巨富。

综上，这道weaken题更像是找到assumption,如果没有E这个条件，那么就会出现上述情况。
