[求助]GWD 1-31

Which of the following most logically completes the argument below?  



laceName w:st="on">DavisonlaceName> laceType w:st="on">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 w:st="on">DavisonlaceName> laceType w:st="on">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‗‗‗‗‗‗.




  • the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices

  • new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested

  • the spring wheat that farmers in the laceName w:st="on">DavisonlaceName> River region plant is well adapted to the soil of the region

  • spring wheat has uses that are different from those of winter wheat

  • planting spring wheat is more profitable than planting certain other crops, such as rye

    Which of the following most logically completes the argument below?  (A)



    Davison River 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 Davison River 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‗‗‗‗‗‗.

  • spring wheat has uses that are different from those of winter wheat

  • planting spring wheat is more profitable than planting certain other crops, such as rye

  • 请教各位此题应该选什么? 起码应该是一个比较句(spring wheat and winter wheat) 才合理啊?

    题目说,农民们正踌躇是钟winter wheat还是spring wheat。二者都可盈利。由于政府对灌溉的限制,winter wheat的亩产量(而非spring wheat的亩产量)远远低于平均值。所以,spring wheat 将会比winter wheat 利润更大,因为:A winter wheat 的低于平均值的亩产量不能被其更高的售价所抵偿。 即,题目的假设是从winter wheat的亩产量低推出其利润也低,这中间忽略了对一种有可能影响推论的因素的解释,即,winter wheat的售价。如果winter wheat的售价明显高于同类且足以抵消其低亩产带来的利润损失的话,那么题目的推论结果就不成立了。所以,为了使推论结果成立,A补充上了对这一可能漏洞的解释。
