42. 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 foreseenable 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?
正确答案：（A）No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia.
我的答案：（E）There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.

题目中光是围绕着“稻米”谈，想必是预设了“稻米是Teruvia主要粮食作物”这一前提吧。
为何答案不是？

如果假设弄不明白你可以取非削弱。e无关，还有other than大金刚。假设原文是把米饭换成燕麦呢？你的答案就很明显的不对了

“other than 大金刚”是什么意思？

other than扩大了原论题的范围，一般是错的。
