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.
[Reveal] Spoiler: OA

Phew!! Tough one bro

Got hung between C and E.

(B) It treats the vague term “poverty” as though it had a precise and universally accepted meaning. -- poverty needs to be defined as same for both the countries. universally sounds broad.
(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. - out of scope
(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.

IMO E. I think C is wrong because the premise talks about absolute numbers in giving the poverty statistics and not the percentages.

IMO E

People in Kuptala might not be poor because all of them earn the same i.e the national average capita income which is nt the case for Bahlton.
A says that no attempt was made to discredit the claim which is wrng too because evidence of poorer people was provided to contrast the claim.
The others are irrelevant.

E it is

In kuptala's case majority of the population earns, about the same as the national average and in Bahlton's case, there is a huge disparity in the earnings of the population. Only this weakens the conclusion

E.

C is wrong, becuase the argument DOES consider the percentage when it says "half" the population lives in poverty. Half is a percentage, not a number.

Definitely E.....

assume incomes of K to be --- A-1, A-1, A-1...... A-1, A+1 A+1 A+1 A+1 (Av=A)
now incomes of B (half are very poor so the other half people must be very rich so that the average income of the whole increase) say A-10 A-15 A-20 A-12 ....... A+20 A+31 (Av=A+1)

Lets just say :-

Per Capita Income :- Kuptala<Bahlton

Poverty :- Kuptala<Bahlton

Both can only be true if There is a Huuuuuge Middle Class i.e. people earning the average.

hence option e..

I know everyone says dont bring outside knowledge, but question like these its okay if you try to learn it in a language that you are most comfortable in .

Two extreme values in the set could alter the average and the obtained value is used to make an analysis for per capita calculation.

E points out this flaw

E makes perfect sense.

Here's the logic: if K has income/capita < B's income/capita --> it is very possible that because K has a lower poverty rate than B then K's residents could be closer to the average ratio than B's residents are to theirs.

Deconstruct the argument:
Avg per capita income in B is higher than K. poverty in K is rare.

How we can achieve this condition at same time:
Lets say Avg for K is 100 and B is 200. Now if all people in K earns from range of 90-110 they are in range of average and NOT POOR. For B half of people earn around 400 and half earn 0. Then average will be around 200.

Check option with this possibility: "E"
