GWD第五套第21题：

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?

No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia.

Not all of the acreage in Teruvia currently planted with rice is well suited to the cultivation of rice.

None of the strains of rice grown in Teruvia are exceptionally high-yielding.

There are no populated regions in Teruvia in which the population will not increase.

There are no major crops other than rice for which domestic production and domestic demand are currently in balance in Teruvia.

除了选项a, 我怎么觉得e也有道理啊，请nn帮着指点一下选项e的正确含义是什么好吗？

原文说的是RICE，E说的是 major crops other than rice ，即使能替代米，使每个人对米的需求量减少（及A），也需要假设能替代米。

C为什么不对啊？

If you think C is correct, you might have misunderstood C. Here it does not matter whether the rice strain is high yield or low yield. If you thought C means the rice strain has potential to grwo more rice per acre, which is apparently a misunderstanding, the argument has said that "...nor will rice yields per acre increase appreciably"

E 的意思是除了大米以外没有其他的农作物的国内生产和需求达到了平衡。属于无关选项，因为就算其他农作物达到了平衡，大米的每人需求量如果不变的话，还是需要从国外进口。

All NN,

Thank you so much! It becomes clearer.

1)       A)说需要稻米的人口上升--->推出结论(,Teruvia will soon have to begin importing rice.)   是这样的意思吗?因为我还是不太懂(A)的意思

谢谢.

     另外,我想

No pronounced trend of decreasing per capita demand for rice is imminent in Teruvia.= any pronounced trend of decreasing per capita demand for rice is not imminent in Teruvia.

对吗??

我现在是不明白什么叫做decreasing per capita demand for rice ？因为不理解这个句子导致我不知道该选哪个了。

scorpio0001

A的意思是：在近期T国中，没有减少人均大米需求的显著趋势发生。取非后，即有减少人均大米需求的显著趋势发生。即人数增多，人均减少，总数仍可以不变。就不需要进口了。所以为not+削弱型假设。

decreasing per capita demand for rice ：减少人均大米需求
