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 demographer's claim must,therefore be wrong.

the argument above is most vunerable to which of the following criticism ?

1.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.

2.It treats the vague term "poverty" as though it had a precise and universally accepted meaning.

3.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.

4.It fails to show that wealth and poverty have the same social significance in kuptala as in bahlton.

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.

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.

E, Per capita income is the average income for year. So only option E correctly critiques the conclusion.

Option E, correctly critiques the argument by pointing out, that the income of most of the people is very close to the average income(per capita);hence, the claims of both demographer's will hold.
