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.

Correct answer is A, why? my answer is E

The whole argument is talking about rice

E is beside the point I think.

No matter what crops are there in T, it doesn't impact on the consumption of rice.

E如果改为“没有其它农作物是供大于求的”而不是ｂａｌａｎｃｅｄ的，那么E是对的

rice的供应量（总亩数×每亩产量）＝Rice的需求量（人口×每人的需求量），在总亩数和每亩产量不增加的情况下，人口增加，只要每人需求量下降才行。
