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 hat 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.

'avg per capita income', this is the crux.
So avg per capita income = total income of city/ population of city.
we need to weaken the argument. Now if City B has 10 really big big billionaires then even if there is 1000 people, the avg would be high. But if in City K there are no billionaires but all working people and pop is still 1000, then the avg would be well kinda avg, but there wouldnt be poor people as all in City K are working ! (assumption yea)
(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.----- Just words. doesnt mean anything. so strike out
(B) It treats the vague term “poverty” as though it
had a precise and universally accepted meaning.--- Again just words. Strike out.
(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.---- Ok, maybe. since City B could have much lower population and City K higher population. But look at the statement again. Nowhere does it speak about % of poverty with population. in fact the words say 'relatively rare in city K', which means poverty just is rare. So strike out.
(D)It fails to show that wealth and poverty have the
same social significance in Kuptala as in Bahlton.--- Again words. Stirke out.
(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. ----[color=#0000ff] Now this is gonna fit exactly under the assumption.[/color]

If we see the options , option E provides one loophole and that loophole is that it signifies the having a large number of people who have low income still the average income could be lesser than a country where few people are there but are extremely rich..hope this explanation helps.
