202. 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 not decrease substantially.
(B) The population of Gortland has remained relatively constant during the country’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.

答案是E，但B为什么不对呢？如果人口下降的话，结论不就不成立了吗？

如果B正确的话也应该是 The population of Gortland will not decrease dramaticaly during the country’s years of growing prosperity.

will not decrease（可constant可increase）和remained relatively constant是有差距的

而且我觉得如果B真给成这样，除非没有E选项，否则还是E更好。不然it takes several pounds of grain to produce one pound of meat这个information就完全redundant的了。
