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
