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.

Responding to a pm:

Let's understand the argument:

"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." -
Say average per capita income of K is \$10,000
Say average per capita income of B is \$40,000

"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."

This is possible with the numbers given above, right? Say, poverty is defined as < \$5000. Say, most people in K earn \$10,000. Very few are less than \$5000 and very few are above \$15000. Say most people lie close to the average.
On the other hand, it is possible that 80% of people in B earn only \$1000. Then the rest of the 20% must have very high income i.e. say \$150,000. In that case, even though average per capita income would be relatively higher, most of the population would be below poverty line.

"At least one of the demographers’ claims must, therefore, be wrong."

This is incorrect conclusion. It is not necessary that at least one of the demographers’ claims must be wrong as we showed above with some numbers.

The argument above is most vulnerable to which of the following criticisms?
(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.

This is exactly what we thought. Incomes in K might be very close to the country's average so that very few people have less than average income (or below poverty line) whereas the gap between in incomes in B might be very high such that many people fall below the poverty line.

E

[AI] of [K] - the average per capita income in the country of Kuptala:
[AI] of [B] - the average per capita income in the country of Bahlton:

[P] of [K] - % people living in poverty in the country of Kuptala:
[P] of [B] - % people living in poverty in the country of Bahlton:

1st claim: [AI] of [K] << [AI] of [B]
2st claim: [P] of [K] ~ 0, [P] of [B] = 50%

The explanation of these visible disparity destroy conclusion: "one of the claims must be wrong"

Only E fully explains that: "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"
In other words, there are a few billionaires in Bahlton

I chose E also. Statement E says that the incomes in Kaptula could be close to the median, and the per capita incomes in Bahlton are more disbursed with lower lows and higher highs.

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.

P1 : Per ca pita income of K < B
P2 : Poverty is rare in K but half the population of B live in extreme poverty
Conclusion : One of the premises (claims) is wrong.

Well this argument is flawed because its making a hasty generalization. If the incomes (per ca pita income) in K are close to country's average then K is indeed prosperous. hence E.

A : This is NOT the case. The argument offers evidence. The problem is that it ignores a vital assumption that the country's average income can be close to per capita income of the country it claims to be poor.
B : The term "poverty" is unambiguous.
C : It does not critiques the argument.
D : No bearing on the argument. Irrelevant

So is poverty unambiguous because it is taken to mean less than per capita income?

could you define the term "per capita income" and "country average" ??

Well per capita income is income per unit of population.

The choice E means that the argument fails to consider the fact that the incomes of people of Kuptala is close to the national average (arithmetic mean) income. Hence poverty is rare in Kuputala compared with that in Bahlton. Hence both the demographers can be true.

5.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.

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)

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)
