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.
E中There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.，除了rice其他的农作物都没有达到供需平衡。---这句话的意思和我们通常设想的答案（这里的人以rice为主食，其他农作物不能取代它。这个作为这里的assumption很合理）这样的假设有很大的出入。其他农作物没有像目前rice一样达到供需平衡（可能是供大于需，也可能是需大于供），如果是前者还说的通，后者就完全不行了。这种带有可能性的选项排除为好
