大全-16-6
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) 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.

還有我發現好像版上有一題標題是大全-16-6,可是好像應該是大全-15-6
可能要麻煩版大改一下~

這是一個平均值與極端值的問題。
樣本是否聚集在平均值附近？ 樣本Sa--(S國平均值)--樣本Sb
還是發散？ 樣本Ta------------------(T國平均值)------------------樣本Tb

仔細看清楚題目應該就差不多了，還有問題的話再討論囉。

關於B，
題目的重點不是討論貧窮的確切水準；此外，這題作者是在同一個時空情境之下針對兩個不同的國家作討論，所以討論貧窮的確切水準沒有意義。
但是在不同的時空背景下就不一樣了，請看：
