This one is for the big leaguers: Batter up!!

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 most violated by the survey described?

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

B) Surveys regarding alcohol preferences are usually inconclusive because many respondants may be intoxicated while being questioned.

C) Eastern European survey methods differ significantly from those of their Western European counterparts.

D) A sample of 400 brands of wine is not considered sufficient to reach a conclusion about the tastes and preferences of the Eastern European country being surveyed.

E) Many wine afficianados, sommeliers and grand sommeliers participated in the survey.

Is it A
I am not good at CR but I think that the only choice that explains the anomaly of differing rating in the two surveys, Approval & Recognition, is A and hence is being violated.

It states that you should not ask respondents questions from the same survey which might be related in some way. It might result in conflicting answers. This is the principle that was violated and hence as per the passage :
The approval rankings of these 27 brands often differed sharply from their recognition rankings.

I'm gonna go with E, if the demographic of the study is too many of the same people, the survey results will be distorted.

A is too strong.

Caught between D and A.

A seems to be winner.

Other options are out of scope.

Took me to answer 3 mins

B after several mns...Had difficulties to understand...

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

out - In the Eastern survey, they could have reasonnably answered correctly to both questions. so not against the rule.

B) Surveys regarding alcohol preferences are usually inconclusive because many respondants may be intoxicated while being questioned.
ok - if it is the case that they are intoxicated, better not ask them-> brake the rule

C) Eastern European survey methods differ significantly from those of their Western European counterparts.
out of scope

D) A sample of 400 brands of wine is not considered sufficient to reach a conclusion about the tastes and preferences of the Eastern European country being surveyed.
out- it is not only about the tastes and pref

E) Many wine afficianados, sommeliers and grand sommeliers participated in the survey.
out- However they can give a clear picture about the recognition and quality->not against principle

A for me ...

If a respondent DOES NOT recognize a brand, he/she will NOT be in a position to rate the product quality. So in the survey for such brand it would always lean towards the same ranking ...

Buzz nailed it right off the bat! The OA is (A). Whereas B-E are principles that may violate (weaken) the survey to a certain extent, only A stays strictly within the scope of the passage, and hence the principle stated: Never ask all respondants a question if it cannot reasonably be answered by respondants who make a particular response to another question in the same survey most violates the survey conducted.

Will go with A.

First of all the other option hardly look like principle.

Second. The passage clearly states that some of the brands of the 400 are not available in the country hence it is unfair to ask people about something which they might have no idea about.
