In Teruvia, the quantity of rice produced per year is currently just large enough to satisfy domestic demand. Teruvia's total rice acreage will not be expanded in the foreseeable future, nor will rice yields per acre increase appreciably. Teruvia's population, however, will be increasing significantly for years to come. Clearly, therefore, Teruvia will soon have to begin importing rice.
Which of the following is an assumption on which the argument depends?
No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia.
Not all of the acreage in Teruvia currently planted with rice is well suited to the cultivation of rice.
None of the strains of rice grown in Teruvia are exceptionally high-yielding.
There are no populated regions in Teruvia in which the population will not increase.
There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.
这种强相关的有问题公式的，直接根据问题公式去推，像e这种拐弯抹角的没有直接提到“个人消耗”的，一般都不是最佳选项，这种题需要直接点出另一个变量：
每个人消耗*人数=rice需求总量；现在说rice总产量不变，人数变多，-》结论说就要进口了；
gap，这里默认了一个变量就是”每个人的消耗“是不变的
Teruvia's total rice acreage will not be expanded in the foreseeable future, nor will rice yields per acre increase appreciably. 种植面积和产量不变
Teruvia's population, however, will be increasing significantly for years to come. 人口将在未来几年显着增加。
Clearly, therefore, Teruvia will soon have to begin importing rice. 不得不开始进口大米。
问假设：
A. No pronounced （明显的）trend of decreasing （per capita** 【demand】） for rice is imminent（即将发生的） in Teruvia. （√）稻米（人均**【需求量】）没有明显下降趋势。即，默认了一个变量--”每个人的需求量“是不变的
E. There are no major crops other than rice for which domestic production and domestic demand are 【currently in balance现在的供需平衡】 in Teruvia. （×）
production will not increase
在未来T的人口会剧增，因此T很快就要进口大米。问assumption
choice a, 人均消耗大米不会显著减少。correct
a中，取反，平均每人需求降低，那么文中论述不成立，此选项也是最直接的
e中，取反，有除了rice之外的其他粮食作物来平衡需求，但是这仍然不能说文中的论述就一定不会发生，并没有说有了其他粮食，rice的需求就会下降。
所以我看到e的other crops就选了，但是E是错的登录 或 注册 后可以参加讨论
做CR一定要全身心投入 整理好逻辑链之后一定要快速地理清楚逻辑链 在心里得到一个intended meaning的答案
假设题要在原文中找信息
错选D
