求一道逻辑题，（答案不是很懂）

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?

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

1. 排他因，取非否定结论 - 饭不变吃的人多了，如果大家一个人少吃点就够了，不用叫外卖
2无关
3无关
4无关，单个不代表整体
5无关

A？
题目：T，米的产量刚好够本国吃。将来T种米的面积不会涨
亩产不会涨，但是人回多，所以T要进口。
A假设人均吃米不会减少

答案应该是A选项。
分析：首先运用有关无关来排除错误选项。E选项明显无关，其他作物的供给是否平衡并不影响水稻的进口与否。在剩下的B、C、D、A中，对每个选项取非，考虑哪一个对原文结论构成了绝对的反对。A选项取非是“在T这个地方近期有一种强烈的对水稻的人均需求下降的趋势”，原文说水稻总产量不能增加，在总供给不变的情况下，总需求如果短期下降，则不需要进口来使供求平衡。不知道我的解释楼主满意否？
