Which of the following most logically completes the passage?

According to the last pre-election poll in Whippleton, most voters believe that the three problems government needs to address, in order of importance, are pollution, crime, and unemployment. Yet in the election, candidates from parties perceived as strongly against pollution were defeated, while those elected were all from parties with a history of opposing legislation designed to reduce pollution. These results should not be taken to indicate that the poll was inaccurate, however, since __________.

B， every candidate whowas defeated had a strong antipollution record
C， there were noissues other than crime, unemployment, and pollution on which the candidateshad significant differences of opinion

这C不是正好反了吗，我觉得是最后问题问，由于下面哪个原因，这个选举结果不应被拿去衡量poll的结果，就是其实voters不是完全按照那个poll的顺序去vote的

这题C选项可以拿有关无关去掉。题目是问Pollution，Crime，Unemployment都好重要，为啥最后被选上的竟然opppose Pollution，解释这个问题。C压根没回答问题。但是D解释了因为选上的三大重要问题中Crime,Unemployment都做的好可以忽略P上的不同。

根据上一次预先选举的投票，大多数的投票者认为政府要去解决三个问题，按重要性排序为：污染，犯罪，失业。然而在选举的时候，强烈反对污染的候选者失败（支持减少污染的），被选举的人都是来自于有反对减少污染的历史的一方。这个结果不是代表这个选举是不正确的
他因：选上那批人很在乎crime 和 unemployment；虽然pollution是3个里面最被选民重视的，但可能另外两个的重视总和超过了pollution

c 选项根本就没有解释，这个相矛盾的想象

这题的逻辑是：民调最关注的是污染问题，可为啥最关心污染问题的候选人落败？只有D回答了这个问题，简言之选举是综合选择，不是单单看污染问题一方面。

摘自GMATclub
The conclusion is, indeed, that "[the election results] should not be taken to indicate that the [last pre-election] poll was inaccurate." Okay, how does the author arrive at that conclusion?

•First, we are given the results of the pre-election poll: MOST voters believe that the government needs to address 1) pollution, 2) crime, and 3) unemployment (in that order of importance)
•In the actual election, candidates from parties strongly against pollution were defeated, and candidates from parties that OPPOSED anti-pollution legislation were elected.

This election result seems to go against the pre-election poll. If pollution is the most important problem for most voters, why would they elect people who are not likely to address the pollution problem? We need something that explains this apparent discrepancy while SUPPORTING the conclusion that the pre-election polls should be taken as accurate...


Quote:

(A) some voters in Whippleton do not believe that pollution needs to be reduced.

The discrepancy is not resolved by this fact. Even if SOME voters don't think pollution needs to be reduced, MOST voters think that pollution is the most important problem. Thus, it is still surprising that the voters elected people from parties that OPPOSE anti-pollution legislation. (A) can be eliminated.


Quote:

(B) every candidate who was defeated had a strong antipollution record

Again, this does not resolve the discrepancy. In fact, this makes the discrepancy even more significant. If most voters think pollution is the most important problem, wouldn't they WANT to elect candidates with strong anti-pollution records? Eliminate (B).


Quote:

(C) there were no issues other than crime, unemployment, and pollution on which the candidates had significant differences of opinion

The discrepancy exists regardless of whether the candidates differed on other issues. The discrepancy is that voters elected candidates who seemingly would not address the problem that voters care about the most. Why? Choice (C) does not help answer this question and can be eliminated.


Quote:

(D) all the candidates who were elected were perceived as being stronger against both crime and unemployment than the candidates who were defeated

Now we're on to something... Imagine a typical voter who believes that the three most important problems to address are pollution, crime, and unemployment, in that order. On one hand, you have Candidate A, who doesn't seem to care about reducing pollution but appears to be strong against crime and unemployment. On the other hand, you have Candidate B, who seems to be strong against pollution, but doesn't seem to be strong against crime and unemployment. Would you rather have the first priority addressed without addressing the second or third priorities? Or are you willing to sacrifice the top priority if it means addressing the other two? You might decide that 2 out of 3 is better than 1 out of 3, even if that means sacrificing your top priority. This would explain the apparent discrepancy, so (D) looks good.


Quote:

(E) many of the people who voted in the election refused to participate in the poll

Remember, we are looking for a statement that SUPPORTS the conclusion that pre-election poll was accurate. By suggesting that the poll was not comprehensive, this statement gives us further reason to DOUBT the accuracy of the pre-election polls. This choice is tempting because it seems to offer a possible explanation for the discrepancy... perhaps most voters who care about crime, unemployment, or other issues did not participate in the poll, making it seem like most voters in Whippleton care about pollution, when in fact most voters (including those not polled) care more about other issues. If (E) is true, we only know that many voters did not participate in the pre-election poll. In order for this to explain the discrepancy, we have to ASSUME that most of the voters who did not participate were voters who do not think pollution is the top priority. And if we make this assumption to explain the discrepancy, we are sacrificing the conclusion by suggesting that the pre-election poll was not accurate. (E) must be eliminated.
