标题: GWD3-21 求指教一道题~请各位nn帮帮我，非常感谢！
GWD5-Q21:
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?

A. No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia.
B. Not all of the acreage in Teruvia currently planted with rice is well suited to the cultivation of rice.
C. None of the strains of rice grown in Teruvia are exceptionally high-yielding.
D. There are no populated regions in Teruvia in which the population will not increase.
E. There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.

我选的是E，不是因为没有其他的粮食可以代替，所以T城市才要进口粮食吗？
为什么答案是A呢？
请各位nn赐教！谢谢~~~
