United Lumber will use trees from its forests for two products. The tree trunks will be used for lumber
and the branches converted into wood chips to make fiberboard.The cost of this conversion would be the
same whether done at the logging site, where the trees are debranched, or at United's factory.However,
wood chips occupy less than half the volume of the branches from which they are made.

The information given, if accurate, most strongly supports which of the following?D

(A) Converting the branches into wood chips at the logging site would require transporting a fully assembled wood-chipping machine to and from the site.

(B) It would be more economical to debranch the trees at the factory where the fiberboard is manufactured.

(C) The debranching of trees and the conversion of the branches into chips are the only stages in the processing of branches that it would be in United's economic advantage to perform at the logging site.

(D) Transportation costs from the logging site to the factory that are determined by volume of cargo would be lower if the conversion into chips is done at the logging site rather than at the factory.

(E) In the wood-processing industry, branches are used only for the production of wood chips for fiberboard.

Some airlines allegedly reduce fares on certain routes to a level at which they lose money,
in order to drive competitors off those routes.However, this method of eliminating competition cannot be profitable in the long run.
Once an airline successfully implements this method, any attempt to recoup the earlier losses by charging high fares on that route for
an extended period would only provide competitors with a better opportunity to undercut the airline's fares.

Which of the following, if true, most seriously weakens the argument?B
(A) In some countries it is not illegal for a company to drive away competitors by selling a product below cost

(B) Airline executives generally believe that a company that once underpriced its fares to drive away competitors is very likely to do so again if new competitors emerge.

(C) As part of promotions designed to attract new customers, airlines sometimes reduce their ticket prices to below an economically sustainable level

(D) On deciding to stop serving particular routes, most airlines shift resources to other routes rather than reduce the size of their operations.

(E) When airlines dramatically reduce their fares on a particular route, the total number of air passengers on that route increases greatly.
不懂啊……我选的D,答案B

7.if transportation costs from the logging site to the factory that are determined by volume of cargo as B says, there are two choices:
(1)if the conversion is done at the logging site, the transportation costs will be based on the volume of wood chips
(2)if the conversion is done at United's factory, the transportation costs will be based on the volume of the branches .
Since wood chips occupy less than half the volume of the branches from which they are made, the transportation costs will be lower.

楼上好牛啊……！我怎么就完全没有想到这个方面呢！！！完全想不到啊！！
我懂了，D是给了新信息的……要用D给的信息和题目一起来判断选项对错……

原文的argument是：
因为：已经降价的路线如果想再提价的话很难，由于对手已经价格比你低，这么做会让你的价格优势失去。
所以：减价的方法不能长期获利。

B：有新竞争者出现的时候会一直这么做的。即，只要有竞争者，我就会降价，你降我也降，怎么着都比你的价格低，以此来赢得顾客。
削弱了 “ attempt to recoup the earlier losses by charging high fares on that route for
an extended period ”这一点。即，不会提价，只会一直降价。

D：无关选项。“考虑要停止一些线路的服务，航空公司决定在这些线路上减少投入的资源而不是减少运营规模”。这个与原文无关><...

楼上说的很详细，但是我还是没拐过来弯啊~~~
我的理解是，argument讨论的是降价是否是个长期行为---答案是不可以，以后没办法提价，没有利润可得。那么削弱选项应该是这个降价方法可行，可以获得利润。也就是说应该讨论的是与利润相关的问题啊~~
但是B选项说的是这个办法可以反复的用来打击对手？？这个和打击对手有什么关系呢？？即使对手被你打败了，那么你也损失了利润啊？？
我选的是E，降价后不仅打击了对手，乘客增多，因此利润也不会有损失，这个降价的方法是可行的。。。

我的思路错在哪里呢？？？请大家指教啊！！！！！

15题我也选了E。E从理论上我觉得也解释得通。但是相比较来说，好像B选项的相关性和题意更切合。因为B也提到了competition的问题，要是在对手降价时你也降价，那个就可以赢得更多的顾客，然后顾客多了就可以获取利润了。

15题的关键在于，在公司降价以后，想通过提升价格来弥补以前的损失的时候，就会有竞争者跟进，用降价的手段来赶走公司，所以B选项就是weak了这个结论说，有新的竞争者来，公司就会继续降价，不让竞争对手得逞。E选项错在，公司降价吸引了顾客，但是这些新的顾客在我提升价格想弥补损失的时候能不能留住，是未知的，所以某种程度上来说这个选项是个无关选项，因为与公司的提升价格的策略无关

弱问一下A错在哪里呢？原文说，该方法不可行是因为无法长期获利；A说法律规定这样的行为不行，算不算提出他因。。。我的逻辑实在非常弱。。。求指点！
