大全-3-15，请教！

In the United States, the Postal Service has a monopoly on first-class mail, but much of what is sent first class could be transmitted electronically. Electronic transmittal operators argue that if the Postal Service were to offer electronic transmission, it would have an unfair advantage, since its electronic transmission service could be subsidized from the profits of the monopoly.

15.   Which of the following, if each is true, would allay the electronic transmittal operators’ fears of unfair competition?

(A) If the Postal Service were to offer electronic transmission, it could not make a profit on first-class mail.

(B) If the Postal Service were to offer electronic transmission, it would have a monopoly on that kind of service.

(C) Much of the material that is now sent by first-class mail could be delivered much faster by special package couriers, but is not sent that way because of cost.

(D) There is no economy of scale in electronic transmission—that is, the cost per transaction does not go down as more pieces of information are transmitted.（A）

(E) Electronic transmission will never be cost-effective for material not sent by first-class mail such as newspapers and bulk mail.

谁能帮我解释一下这道题是什么意思啊?Electronic transmittal operators 所说的又是什么意思？

谢谢了！

想向大家求证一下:

文章中的"it (Postal Service)would have an unfair advantage", 这里的advantage是相对于private operators而言吗?

如果是的话, 这个advantage不是也可以给Postal Service带来monopoly吗? 所以我选了B.

而且,尽管"electronic transmission service could be subsidized from the profits of the monopoly", 也不一定意味"it could not make a profit on first-class mail". 所以A不一定对.

我的思路哪里有问题?

请大家帮助, 谢谢!

这个advantage是Postal Service的优势；请注意SC的原则在这里也适用。

文中最后一句已经说了： could be subsidized from the profits of the monopoly.

潜龙勿用

注意原文所问的问题:Which of the following, if each is true, would allay (减轻, 减少) the electronic transmittal operators’ fears of unfair competition? 该问题实际上是削弱原文的结论:it would have an unfair advantage. 而在原文中,结论和论据之间的核心连接元素是profits. 找到了这个link of element,你就知道为什么A选项是答案了.

实在不好意思, 把allay看成ally了, 以为有联合、符合的意思，那就变成加强了。

而D所以不对是因为它concern的是cost，而不是proviate所担心的profit了是吗？

偶还是有疑问，为什么D就不对呢？D说对于electronic transmission来说，没有规模经济的效果，也就是说单位成本不会因为数量增加而降下来，那不是也正好说明了垄断不会产生unfair advantage吗？垄断会使订单都集中在PS，但却不会降低它的单位成本。。。而且原文也没有unfair advantage一定系指profit啊，也有可能是cost efficiency啊

偶觉得D很有道理啊，请指教。。。

我也同意楼上的，D为什么不对呢？

文中的profit of monopoly 指的是electronic transmission service因为可以垄断first mail，所以设定高的价格来获得利润。

而A中，直接说electronic transmission service 其实不能获得利润，直接反对了造成了unfair advandatge的原因，所以是正确的。

提干中 operators攻击 PS的理由是他们会用first mail的利润来补贴electronic transmission的亏空,

而D说的是单位成本, 在提干中并没有出现, 考虑的是总成本, 所以不能算有效削弱

但A确实是削弱了operators的攻击理由, 说明如果他们作electronic transmission,就不会有first mail利润, 反过来证明他们不会作electronic transmission

超级容易的一道题，

ALLAY缓和，就是削弱！

OPERATOR反对，就是因为觉得邮局如果提供电子上的FC会利用其垄断地位获得利润，造成一种不公平，如果没有利润，不就是推翻了这个UNFAIR
