标题: GWD 7-21 我的思维误区

虽然觉得A很好，但E好像也很有道理

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.

人口增加----必须进口大米。人口*需求=大米总销售

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.假设取非
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.[A]

E的意思是除了大米之外没有其他主要的庄稼国内产需平衡属于无关选项
