标题: gmatpill上的一道逻辑题~~~
gmatpill上的一道逻辑题~

Shortly after the popular chat app "WhatsUp" was acquired by media conglomerate MediaCorp, several advertisers have withdrawn their advertisements from the mobile app, claiming that it was due to the fact that the parent company took the chat app in a new direction and made changes that did not protect users' privacy, making users' current location too readily available to other app users. Surely this indicates that the decision-makers in advertising companies do still have a sense of moral propriety that occasionally drives their actions.
Which of the following, if true, would strengthen this conclusion?
(A) The advertisers review the placement of their advertisements on a daily basis.
(B) It is a quite unusual for several advertisers to withdraw all their advertisements simultaneously from a mobile app.
(C) The advertisers, when questioned, admitted that their clients would lose significant revenue as a result of the advertisements being withdrawn.
(D) The advertisers all placed new advertisements in other mobile apps that had no such concerns regarding user privacy.
(E) A review of the mobile app suggested that the majority of the users believe that the standard of the mobile app's contents had failed since being acquired.

前提：因为新收购的app存在“不 protect users' privacy”的问题，广告商决定收回广告
结论：广告商的决定有moral propriety的影响

额。。。对选项C D很纠结啊

C选项：暗含意思广告商没有把高收入作为决定的影响因素，应该属于他因排除

D选项：The advertisers all placed new advertisements in other mobile apps that had no such concerns regarding user privacy. 引入证据说明广告商的确是因为privacy的问题收回广告

我觉得两者都有加强的含义啊，针对的点都是claiming that it was due to the fact that the parent company took the chat app in a new direction and made changes that did not protect users' privacy 这句话
C / D选项从他因排除/事实这两个角度都加强了这句话不是吗？

不明白...我排除C的原因是C说的是广告商的clients会损失很多收入，那这个说的是clients作决定时候考虑道德问题而不是广告商做决定时候考虑道德问题。我认为C反而削弱了，因为C里面损失收入的主体是clients而不是广告商，如果广告商在损失收入的情况下依然做了这个决定，那才能加强结论，但这里C说的并不是广告商。
表示不理解

这个是gmatpill instructor 的解释，instructor仿佛用常识把clients和广告商两个的 likely 逻辑关系连到一起了。
而且instructor认为D选项是不相关或者削弱了。。。。。

First, although (C) may not prove the conclusion, it certainly strengthens it more than any of the other answer choices, which are either not relevant or weaken the conclusion. For the GMAT, we need to choose the best answer, which is not always perfect.

Second, by definition, clients usually pay companies or people in exchange for goods or services. While it may not be true without a doubt, it certainly is likely that the advertising companies will lose money from their clients if the clients are making less or even losing money.

[摊手]
我之所以排除C因为我还有一个考虑，因为C要成立必须要证明client的收入降低会导致广告公司收入同样的降低，那这里的假设就是广告公司和客户之间签的合同是按照广告收入按比例提成的，如果是固定费用情况就不一样了。虽然我不了解广告行业，但是我觉得不能直接脑补合同就是按比例提成所以client收入降低会导致广告公司收入降低。如果可以这么脑补，那我也能脑补这个决定是由客户提出的，因为客户的道德准则更高，那么就说明撤广告是客户的选择而不是广告公司的选择，那就削弱了论证。综上无论能不能脑补我都不认为C是对的。

至于选D，并不是因为其他不好只能选D，而是我认为D就是对的。因为如果广告公司把这个广告从whatsapp应用里撤下来而转到其他没有泄露用户资料的应用里，那么就说明不是别的原因而是由于道德考虑才做的决定。因为这里面的区别只有道德考虑而没有别的任何因素。

官方给出的解释里的第一条我觉得没啥用，CR里面如果一个答案是对的那就是对的，又不是SC里面一个wordy就可以pass掉一个。SC里面读着不顺或者不合常规，但是其他有语法错误的可以排除只能选它。但是CR里面谈论的是逻辑，逻辑对就是对，错就是错，无关就是无关，单单一句certainly strengthens more我觉得和没说一样。

第二条就是我之前说的，除非广告商在损失收入的情况下依然做了这个决定，那才能加强结论。但是这个是需要脑补的，而且还可以脑补出别的相反效果的内容。于是我就不理解了。
希望有更多人能交流一下，也许我的思路错了但至少让我知道错在哪里了。

恩恩~ 我也希望有更多的人可以交流一下这道题~

另外说明一下，我不知道这个instructor是不是gmatpill 官方认证的，还是自己后缀加的~

所以实际上我也是不能100%确定正确答案是C （因为我做的free test 并没有花重金买答案）

但是能确定gmatpill认为答案不是D，因为我选的是D，然后显示了大大的叉 ==！

我的思路和devilmars的一样，没想明白为什么C对。。。

跪求大神来答疑~

摘自beat the gmat：

(C)The advertisers, when questioned, admitted that their clients would lose significant revenue as a result of the advertisements being withdrawn.

This answer choice is the only one that in any way supports the argument. If the advertisers would lose revenue as a result of withdrawing the advertisements there must be some non financial reason for their having withdrawn the advertisements. While this answer choice does not clearly point to one reason, it does eliminate a reason. So in a sense it supports the conclusion, at least more than any of the other answer choices do.

(D)The advertisers all placed new advertisements in other mobile apps that had no such concerns regarding user privacy.

If anything this weakens the conclusion in that it conflicts with the idea that advertisers are concerned with user privacy.
