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.
