理应是A
楼主自己搜一下，最近刚刚讨论过。
作者: butterfinger 时间: 2005-10-17 00:01
不好意思 17题我只找到这个讨论贴 可以给个连结嘛
BTW 看不太懂A选项的意思
on lightly traveled sections of major highways only.当初乍看之下以为是现在运用TRIPEL的卡车只在一点点的范围
那不就意味着鼓励使用TRIPLE就可运用在更多方面 继而降低死亡率
我想我大概是哪里搞错了
请各位NN指教

28-17: In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria’s roads but are involved in 12 percent of all highway fatalities. The very largest trucks – those with three trailers – had less than a third of the accident rate of single- and double-trailer trucks. Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.
Which of the following, if true, most seriously weakens the argument?
A: Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.
B: No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.
C: Very few fatal collisions involving trucks in Partoria are collisions between two trucks.
D: In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
E: In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks
My best guess is B? Do you have any input?
同问。怎么感觉A象是在加强？还是偶没有看懂A选项？
斑竹NN赶快出手指点啊。。。快要考了。谢～

因为最大的卡车现在只在高速公路上的车辆较少区上行驶,所以事故少,但这种车也大量使用的话,可能事故比轻型卡车还多.

谢谢楼上的解释，这题的A就没读懂..........现在就明白了

vote E the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks 会使得triple-trailer truck 出车增加 事故机率上升 weaken 结论
作者: fengyun1 时间: 2006-8-31 13:00
不会呀。triple-trailer truck <=3 single-trailer trucks，出车率比single-trailer trucks少了。不过这好像与weakens the argument无关。你是说和triple-trailer truck 自己比，原文也没建立出车增加---〉事故机率上升的逻辑吧。

文章結論是說, 由於調查中結果發現三節卡車比二節/一節卡車出車禍事故少, 所以只要都換成三節大卡車就可以降低出車禍事率.
問要削弱結論.
選項A. 是說三節大卡車一直以來都只有在比較少車流量的高速公路路段行走.
所以只有A 可以削弱結論. 因為A 說明了車禍事故的背景(路段)情況不同, 所以可以證明原文的結論並不能成立.
A: Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.

w我选E

A中
artorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.
trucking companies 卡车公司让三节车只在路况好的告诉公路行驶,并不能代表整个Partorian 地区所有的三节卡车都如此. 故A选项以偏概全，错！
支持E,这其实是一道数学题。就像前面有一题雨量的CR
按照题设：The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and double-trailer trucks.
而如果E的话，假设运同样一批货物，一节卡车运的次数为3，那么三节车运的次数肯定多于1次。想想如果某批货动用3量一节卡车，那3节车的哥们就得跑两次。这样根据less than a third of the accident rate ，这还指不定这个替代方法是好的。所以E削弱

我不同意你的说法,
楼上说"而如果E的话，假设运同样一批货物，一节卡车运的次数为3，那么三节车运的次数肯定多于1次。"
对,没错,如果你要计算的话. 但是没说必须按照你计算的这么做啊.其实,E应该是无关选项.
我支持A.
A用一个他因解释原文的冲突点,从而削弱原文论点.

A
事故发生率和卡车节数的关系
三节卡车少发生事故
所以原文认为事故发生率与三节卡车有关
引入他因，是因为三节卡车一般都在车比较少比较宽松的公路上行驶
直接weaken
关于E
E: In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks
因为三节货车的法定载货量比一节货车的三倍载货量少
首先 maximum 这个词，只是说最多，但是实际情况装多装少就不知道了
其次 e只把三节和一节比，没和二节比，比较缺失状态
