B it is,
No resident of Country X should consider the loss of the traditional tribal structure to be a tragedy. When tribal traditions dominated the culture of Country X, the economy was extremely depressed. However, since the loss of the tribal tradition, Country X has experienced the fastest growth of any economy on the continent. Per capita income has increased more than twentyfold, the trade deficit has become a trade surplus, and the unemployment rate is at an all-time low.
Which of the following questions, if answered, would be most helpful in evaluating the validity of the argument above? How can we be sure that loss of tribal traditions has caused this and thus not consider loss of tribal traditions as tragedy
(A) How long did tribal structures in Country X exist before they were lost? Irrelevant
(B) Is the tribal structure the only part of traditional culture that Country X has lost?Relevant, if this is the only change then it validates the argument. On the contrary, if it is not the only reason you can make up many others. So this is useful in establishing the validity of the argument
(C) Are there any other countries with similar tribal structures that have also experienced recent economic growth?We do not need other examples, if they are there its good, if not there then also its okay
(D) What percentage of residents in Country X considers the loss of traditional tribal structures to be a tragedy?the author says no resident, so percentages here don't come into the picture
(E) Are there any sectors other than high technology that have experienced an increase in jobs? High technology, seriously ! where did this come from ? Totally irrelevant.
