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.

Please explain... thanks

I'd go with E.

Let's say the poverty line is $20,000.

In K, 50% of the population makes $15K and 50% makes $35K for a per capita income of $25K.

In B, 90% of the population makes $10K and 10% makes $500K for a per capita income of $59K.

Thus, we can see that it's entirely possible for both statements to be true.

Hi Bill,

Very nice explanation for option E. Please also explain why not C?

K – Let us say avg. per capita income $12K. 50 people live under poverty out of total population of 2000.
B - Let us say avg. per capita income $15K. 50 people live under poverty out of total population of 100.

This also makes both statement true.

Thanks in advance.
