Question Stats:

76% (01:44) correct 24% (02:28) wrong based on 1 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 grain 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 Gortland will soon decrease.
(B) Importing either grain or meat will not result in a significantly higher percentage of Gortlanders' incomes being spent on food than is currently the case.
(C) The per capita consumption of meat in Gortland is increasing at roughly the same rate across all income levels.
(D) The per capita income of meat producers in Gortland is rising faster than the per capita income of grain producers.
(E) People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain.
[Reveal] Spoiler: OA

KUDOS
-increased per capita meat consumption
-several pounds of grains-->one pound of meat
(a hen eats 8 kg of grains in its lifetime and then only we can get a Kg of meat from it)
-production of grain is constant

City will suffer shortage of meat and grains so import will fulfill the demand of the people.

Assumption should be something which can provide us the link which should state that meat is getting consumed more and more, also the grain is getting consumed more than before or atleast same as before.

(E) wins.

I chosed C but now I see the mistake. I guess this is one defender assumption question. The assumption helps to defend the conclusion by eliminating events which migth affect the ocurrence of the conclusion. See more on the topic in the CR Bible
