LSAT-14-4-22

22. In a survey of consumers in an Eastern European nation, respondents were asked two questions about each of 400 famous Western brands: whether or not they recognized the brand name and whether or not they thought the products bearing that name were of high quality. The results of the survey were a rating and corresponding rank order for each brand based on recognition, and a second rating-plus-ranking based on approval. The brands ranked in the top 27 for recognition were those actually available in that nation. The approval rankings of these 27 brands often differed sharply from their recognition rankings. By contrast, most of the other brands had ratings, and thus rankings, that were essentially the same for recognition as for approval

Which one of the following, if each is a principle about consumer surveys, is violated by the survey described?

(A) Never ask all respondents a question if it cannot reasonably be answered by respondents who make a particular response to another question in the same survey

(B) Never ask a question that is likely to generate a large variety of responses that are difficult to group into a manageable number of categories

(C) Never ask all respondents a question that respondents cannot answer without giving up their anonymity

(D) It is better to ask the same question about ten different products than to ask ten different questions about a single product

(E) It is best to ask questions that a respondent can answer without fear of having gotten the answer wrong.

答案是A


读完题能感觉A是对的,但如果让我给别人解释为什么A对,我肯定表达不清。


看了以前的帖子,mindfree以前这样解释:A对是因为被survey的人被问及他们不熟悉的品牌(第一个问题), 然后还被问到对这些品牌的品质(第二个问题). 第二个问题不可能reasonably answered. 所以A正确.



还是没有完全理解,应该还是出在阅读上,哪位兄弟或姐妹能受累把从“The results of the survey were a rating and......到结尾”给大概翻译一下,多谢了:)

这是lawyer 的解释,我觉得很清楚,不知道你看没看到。

1。问题分析:本题是PRINCIPLE题,而不是解释题,不必解释原文现象,只要内容和原文对上,形成一般特殊关系就行。问题要你找一个原则,这个原则要你别那样做,原文的调查却做了。其实就是原文怎麽做,加个否定词(NO,NEVER等等)就是答案。

2。原文的意思是:关于400个名牌问消费者两个问题:知名度(RECOGNIZED)和质量认可度(APPROVAL)。27个国内品牌两者排名差别大,其他品牌(注意原文没说是国内还是国外品牌,所以我们不知道,关于27个品牌外的牌子,其实原文给的信息很少,只知道两者排名差不多,其他都不知道)两者排名大体相同。

3。答案分析:A将NEVER去掉,就是问消费者两个问题,其中一个不能被合理回答。原文正好是这样。从原文那27个品牌两者排名差别大可看出有一个问题不能被合理回答(注意不是去解释它,所以不必推测为何会差别大,原文也没说,不知道)。其他选项和原文没法重合,形成对应关系,故排除。
