Demographers doing research for an international economics [#permalink] New post 29 Dec 2010, 17:07

Question Stats:

58% (02:23) correct 41% (02:07) wrong based on 1 sessions
Demographers doing research for an international
economics newsletter claim that the average per
capita income in the country of Kuptala is sub-
stantially 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 can someone explain this

Its very late here but I'll give it a shot :)

Claim 1 Kuptala = lower average income per capita
Claim 2 Bahlton = higher average average income but >50% in poverty (much higher than Kuptala).

Argument: This doesn't make sense, one claim must be false.

One way this can be true is if the income divergence is substanially higher in Bahlton than Kuptala. Meaning, they have a few people earning all the money and the rest is living on the street. (Answer E)

This one is like strenthen question -
"whereas poverty is relatively rare in Kuptala, over half the population of Bahlton lives in extreme poverty." - you have to strengthen everything after "whereas" keeping in mind that both the claims are true. E does that since it means Kuptula is indeed NOT poor bcos Kuptula and Bahlton have different average per capital income.
