GWD1-31 Which of the following most logically completes the argument below? 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‗‗‗‗‗‗. A. the smaller-than-average size of a winter wheat harvest this year would not be compensated for by higher winter wheat prices B. new crops of spring wheat must be planted earlier than the time at which standing crops of winter wheat are ready to be harvested C. the spring wheat that farmers in the Davison River region plant is well adapted to the soil of the region D. spring wheat has uses that are different from those of winter wheat E. planting spring wheat is more profitable than planting certain other crops, such as rye
答案是A 但为什么不选B?
我能理解A的意思 说高价不能弥补低产 但是既然原文已经说了 equally profitable,原文忽略成本,也就是说 w产量*w价格 = s产量*s价格 w产量下降导致 w产量*w价格 < s产量*s价格 那么A选项higher这个词多余 即使去掉或者lower,A也是对的 (higher提示这是答案?) A选项的作用为复述原文条件
B是原文基本假定 w和s不能都种 如果B不成立 那就w,s一起种了 有可能导致w + s > s 有人会说 w有可能亏本 造成w + s < s 但原文并未提及成本 选项A有可能造成w亏本,但不能作为已知条件
个人认为这题是加强题 加强最后一句的结论 由于原文已经可以推得 s > w 不需要选项A来重复条件 因此B阐述假定连接gap 要比复述原文条件的A好
是的我在钻牛角尖我是sb  请各nn大虾xdjm告诉我我对A和B的理解哪里错了 谢谢 |
