Gortland has long been narrowly self-sufficient in both [#permalink]  18 Jan 2007, 04:24

Question Stats:

86% (02:11) correct 13% (01:14) wrong based on 18 sessions
Gortland has long been narrowly self-sufficient in both grain and meat. However, as per capita income in Gortland has risen toward the world average, per capita consumption of meat has also risen toward the world average, and it takes several pounds of grains to produce one pound of meat. Therefore, since per capita income continues to rise, whereas domestic grain production will not increase, Gortland will soon have to import either grain or meat or both.

Which of the following is an assumption on which the argument depends?

(A) The total acreage devoted to grain production in Gortlnad will not decrease substantially
(B) The population of Gortland has remained relatively constant during the countryâ€™s years of growing prosperity
(C) The per capita consumption of meat in Gortland is roughly the same across all income levels
(D) In Gortland, neither meat nor grain is subject to government price controls
(E) People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain

The answer seems to be E

However, my understanding is that, if meat consumption increases and grain consumption decreases(negating E), it shouldn't affect the conclusion because the conclusion says " Gortland will soon have to import either grain or meat or both" .. this is a either, or, both statement.. so why wouldn't gortland import meat alone even if the grain consumption decreases. it still doesn't hurt the conclusion?

option e looks like a good choice
because if people start eating meat their grain consumption ll decrease

(A) The total acreage devoted to grain production in Gortlnad will not decrease substantially
Even if it is not the case,Gortland will still need to import.

(B) The population of Gortland has remained relatively constant during the countryâ€™s years of growing prosperity
Doesnt matter even if it increses or remains constant. (reduction I am not sure of)

(C) The per capita consumption of meat in Gortland is roughly the same across all income levels
No mention of income level required.

(D) In Gortland, neither meat nor grain is subject to government price controls
Out of scope.

(E) People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain
Kind of fits in.

Can anyone help me how to think on each line?I kind of just eleminate the choices.

Yes, E should be the answer. If the consumption of meat is increasing and at the same time the consumption of grain is decreasing proportionately then Gortland will not import.

E was my answer, however at first I coudn't choose between E and B, then I realised why B doesn't work:

The reason I worked out that B doesn't work is that the conclusion DOES rely on the population not DECREASING but because growing population (thus population not stable) would support the conclusion, this option isn't right.

(B) The population of Gortland has remained relatively constant during the countryâ€™s years of growing prosperity
(C) The per capita consumption of meat in Gortland is roughly the same across all income levels

(E) People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain-->CORRECT

Remember to identify the conclusion whenever you do an CR question. Now use the Negate approach with answer E:

Let's say: Normally Gortland consumes: 1000 Grain and 1000 Meat, equal to what the country can produce; and the exchange rate is 4G --> 1M

If now the consumption is: 800G and 1100M --> Gortland can exchange extra 200G to 50M, so it actually produces 1050M, still need to import another 50M
If now the consumption is: 700G and 1100M --> exchange extra 300G to 75M, so still need to import another 25M
If now the consumption is: 600G and 1100M --> exchange extra 400G to 100M and Tah-da! Gotrland does not have to import anything at all --> against the conclusion

That's why we need to assume the consumption of grain will not decrease radically. The OA is E
