Demographers doing research for an international ecomonics 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 vulnerable to which of the following critisms?
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 possiblity that the number of people in the two countries who live in poverty could be the same even though the percentages of the two same 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 possiblity that incomes in Kuptala, unlike those in Bahlton might all be very close to the country's average per capita income.
The argument is that one of the claims to be wrong. But if all the residents of K have income close to the per capita range ....... then poverty is less. wheras........ huge deviations in salary can give the general idea of a larger per capita..... as in the case of B.
It may be possible that income of each individual in Kuptala is very close to it's average per capita income.
Whereas it may be possible that in Bahlton, there is a big difference between the income of two individuals.
E for me too ... its the question of standard deviation ... if almost all people are along the lines of avg .. then there wud be no case of extreme povery as well as extreme richness ..but if the deviation is higher then although average migh be better than in the previous case ..but there wud be greater number of cases in both the extreme categories. _________________
