Q31:

Which of the following most logically completes the argument below?

laceName>DavisonlaceName> laceType>RiverlaceType> farmers are currently deciding between planting winter wheat this fall or spring wheat next spring.  Winter wheat and spring wheat are usually about equally profitable.  Because of new government restrictions on the use of laceName>DavisonlaceName> laceType>RiverlaceType> water for irrigation, per acre yields for winter wheat, though not for spring wheat, would be much lower than average.  Therefore, planting spring wheat will be more profitable than planting winter wheat, since‗‗‗‗‗‗.

B, C, D, E are all irrelevant, so only A is left.

The question is asking for an evidence that can support the conclusion.  This is a variation of assumption question.  You can try deny test.

Deny A, we get "the smaller-than-average size of a winter wheat harvest this year would be compensated for by higher winter wheat prices".  If so, the conclusion "planting spring wheat will be more profitable than planting winter wheat" will fall apart.  Therefore, A is an necessary evidence -- A is the best answer.

请问这位好心人，Compensated for by higher winter wheat prices 中的 higher winter wheat price 是什么意思啊， 我当时的理解是后来 winter wheat 所卖的价格，但是后来觉得如果是当时为了plant 而花的买 winter wheat price  

原文意思：冬麦和春麦收益常差不多。新政府的规定使冬麦产量比春麦低。所以种春麦收益好点（指新政府规定后）。原因。。。（实质是找个支持结论的理由）。

答案：因为结论是比较两种麦的收益。其他选项都和两者的收益无关。只有A。A说冬麦卖的价格高点，但顶不了产量的减少。春麦的收益还是要好点。

建议：对原文意思的理解，要以原文为依托，不能猜，特别是逻辑题。冬麦价格就是冬麦价格，不是种子。

new crops of spring wheat must be planted earlier(->later) than the time at which standing crops of winter wheat are ready to be harvested

right? cannot affect the conclusion

呵呵，谢谢。
