[求助]大全-D-7

<< 发个牢骚….大全D  ß-正确率史无前例的D !!

哇哇哇……谁偷走了我的脑浆 >>

7.     The postal service is badly mismanaged. Forty years ago, first-class letter delivery cost only three cents. Since then, the price has increased nearly tenfold, with an actual decrease in the speed and reliability of service.

Each of the following statements, if true, would tend to weaken the argument above EXCEPT:

(A) The volume of mail handled by the postal service has increased dramatically over the last forty years.

(B) Unprecedented increases in the cost of fuel for trucks and planes have put severe upward pressures on postal delivery costs.

(C) Private delivery services usually charge more than does the postal service for comparable delivery charges.

(D) The average delivery time for a first-class letter four decades ago was actually slightly longer than it is today.（E）

(E) The average level of consumer prices overall has increased more than 300 percent over the last forty years.

     我想请教 ( C ) 选项

     题意应该是   邮资调帐 然 服务水平降低

              ( C ) 快递的收费较高 !

              ( C ) 选项可以作为WEAKEN的逻辑为合 ?? 可否请大家帮我厘清一下

我也觉得(C)没办法削弱题目的主张耶…

正确答案为什么不是(C)而是(E)呢?

(E)说明first-class letter delivery cost的提高并非因为经营不善，而是由于整体消费水平提高的缘故，所以应该可以weaken题目的主张，不是吗？

我也迷惘了…

Private delivery services usually charge more than does the postal service for comparable delivery charges.

∵ Private delivery services $＞The postal service$

推论

è若the postal service比快递贵就有为常理  则 铁 mismanaged.

∴ 没有mismanaged  è暗喻 定价还在合理范围内

虽然C选项设计的狠烂 但相较于E  C 绝对是一个比较倾向于weaken的选项

以上为我的推论  请大家继续讨论噜 ^^

本题为现象解释型

现象：邮政服务价格猛涨，速度和可靠性下降

结论是对这种现象提出一种解释：管理不好导致这些。

A，B，C，D分别对这种现象提出不同解释

A。处理量大增导致速度和可靠性下降

B。燃料费大增使价格上涨

C。私人同种服务还贵，说明价格涨十倍是正常的，言下之意是大体环境价格都涨了，不仅仅是邮政一家涨。而且还可能邮政服务是偏宜了，使速度和可靠性下降

D。四十年前更慢

E。通货膨胀才3倍，而邮政服务却涨10倍，贵，而服务却不好，说明是管理不好的可能性很大。---有点支持

故选E

OG-137. A study of marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which both partners follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles can seriously jeopardize a marriage.

Which of the following, if true, most seriously weakens the argument above?

(A) Married couples in which both spouses follow the same sleeping and waking patterns also occasionally have arguments than can jeopardize the couple's marriage.

(B) The sleeping and waking cycles of individuals tend to vary from season to season.

(C) The individuals who have sleeping and waking cycles that differ significantly from those of their spouses tend to argue little with colleagues at work.

(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses. D

(E) According to a recent study, most people's sleeping and waking cycles can be controlled and modified easily.

选项A和大全D-7的C特别类似。

D-7/C是说私人服务的价格也高。

OG-137的A是说 睡眠习惯一致的夫妻也会吵架。

OG对A的解释是，文章的assumption不是说睡眠习惯一致是唯一的影响婚姻的理由，所以不能选。

同理到D-7C里也是一样，题干也没说badly management是价格高，服务差的唯一理由。所以我觉得也不能weaken结论。

请指教，多谢！

我觉得OG137的A和D7的C不是一回事，OG的A不存在比较关系，而D7的C通过与Private的比较得出post service与大环境比较价格其实还处在一个较低的水平。我觉得lawer解释得很清楚。

其实C是用另外一个现象来说明price上涨与mismanagement不是因果关系

而E则是排除他因，进一步指出就是mismanagement导致价格上涨的。
