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

【正确答案】 A

【答案解析】[解析] 调查报告的结果显示，位于27名以后的商标的认识和认可的排序是一样的，由此我们可以推出应答者若不能对本调查报告中的一个问题合理地回答时，他往往也很难合理地回答另一个问题。因此很明显本题描述的调查报告违反了(A)选项所描述的原则；(B)、(C)、(D)和(E)四原则都是本题的调查报告所遵循的原则。
