Of the countries that were the world’s twenty largest exporters in 1953, four had the same share of total world exports in 1984 as in 1953. Theses countries can therefore serve as models for those countries that wish to keep their share of the global export trade stable over the years.

Which of the following, if true, casts the most serious doubt on the suitability of those four countries as models in the sense described?

(A) Many countries wish to increase their share of world export trade, not just keep it stable.
(B) Many countries are less concerned with exports alone than with the balance between exports and imports.
(C) With respect to the mix of products each exports, the four countries are very different from each other.
(D) Of the four countries, two had a much larger, and two had a much smaller, share of total world exports in 1970 than in 1984.
(E) The exports of the four countries range from 15 percent to 75 percent of the total national output.

These countries don't keep stable their share.

D means that 4 countries in question had no stable trade, hence cannot serve as the model

when you answer a CR question first thing you have to figure is: what is the conclusion and what are the pramises. here the con. is: they will keep exports the same since they kept it stable in the past. so you have to find an answer that would " cast doubt" on this con. so the fact that answer D) Of the four countries, two had a much larger, and two had a much smaller, share of total world exports in 1970 than in 1984. shows an instability in the past for these countries... by itself will cast doubt on the con.

by the way casting doubt, does not have to be very strong. in most of the tougher questions the right answer choice will create a very low level of doubt and the wrong answer choices are statements that sounds to show very high degree of doubt, but they do that for the premises or the subsidiary conclusion not the main conclusion of the argument... so watch out for these type of traps in the answer choices...

main thing would be to figure what is the main conclusion of the argument.... then you can easily solve the problem

my bet is on D because the conclusion of the argument is that, those 4 countries can be considered as model because they are stable.

my take option D..
As the four countries has differed in share in 1984 and therefor can't be served as a model.

Which of the following, if true, casts the most serious doubt on the suitability of those four countries as models in the sense described?

(A) Many countries wish to increase their share of world export trade, not just keep it stable.
(B) Many countries are less concerned with exports alone than with the balance between exports and imports.
(C) With respect to the mix of products each exports, the four countries are very different from each other.
(D) Of the four countries, two had a much larger, and two had a much smaller, share of total world exports in 1970 than in 1984.
(E) The exports of the four countries range from 15 percent to 75 percent of the total national output.



Four countries out of twenty have maintained their share at the same level in 1984 as they were at 1953. Now, for them to be models, they should satisfy some of the conditions:

1. Their exports should have also increased by the same amount, so as to maintain the share.
2. Other countries exports should have fallen.
3. Their share should have remain stable even between the years given. it should not be the case that there is very high volatility in exports between the years and stability at the end points.


They would not be treated as models, if their exports have not increased in order to maintain share, volatility has increased, or exports of other countries has shown secular increase overtime.


Out of the four choices given, D seems best answer because it shows volatility in mid years, which cast doubt over them being models.

I was confused between A and D.
But then I again read the conclusion and understood that the conclusion is talking about only those countries that wish to keep their share of the global export trade stable over the years.

A says - Many countries wish to increase their share of world export trade, not just keep it stable
That's why A is irrelevant.

Premise: Of the twenty countries, 4 countries have same share of global exports in 1984 as they had in 1953.

Conc: These countries are models for those countries that wish to keep their share of the global export trade stable over the years.

Note that conclusion talk about the stability of exports over the years but premise only mention that 4 countries had same exports in just two years. The assumption here is that in the years between 1953 and 1984, exports of those countries remained stable. Since we are supposed to weaken the argument, we need to find an option that suggests that exports were not stable in the years between 1953 and 1984.

Lets do the POE.

Which of the following, if true, casts the most serious doubt on the suitability of those four countries as models in the sense described?

(A) Many countries wish to increase their share of world export trade, not just keep it stable.

This is out of scope as we are only concerned about whether those 4 countries could keep their exports stable over the years as otherwise those countries cannot serve as model for other countries.

(B) Many countries are less concerned with exports alone than with the balance between exports and imports.

Similar to option A, this is also out of scope.

(C) With respect to the mix of products each exports, the four countries are very different from each other.

We are only concerned about those countries could maintain their share of total world exports over the years. The variation in the mix of products that they exported is not really a concern here. Eliminate.

(D) Of the four countries, two had a much larger, and two had a much smaller, share of total world exports in 1970 than in 1984.

This is correct as it points that in 1970 the share changed so those countries were actually not stable over the years so they cannot serve as model.

(E) The exports of the four countries range from 15 percent to 75 percent of the total national output.

This is incorrect as we are not concerned with the share percentage of those countries. We are only concerned with the stability of that share over the years.
