[CR. ] PP1-19

[amysky0205 (=Amy=)]

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.



income增加，買meat增加，生產meat的grain不會增加
--> G國很快就需要進口grain, meat或both

OA: E

想請問B的排除
是因為income花在那裡不是重點嗎?

謝謝

推 Dayton119:如果把B看成進口會造成花費比例改變 代回原文也不能推翻
推 Dayton119:因為進口的也不會改變價格（消費）但主因是GDP成長才會
→ Dayton119:應該拉
