Critical Reasoning

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.

A not Sure

OA - A

official explanation follows :

In rather an odd survey, consumers living in an Eastern European nation are asked to rank

400 Western products according to brand name recognition and quality. But it turns out

that only 27 of the products are even available in that nation. Not surprisingly, the survey

results for the 27 products that are available (in terms of how name recognition correlates

with perceived quality) were unlike the results for the products that aren't available.

What's the point of asking people about the quality of products they've never used? The

survey violates (A): Although all the respondents can answer the question about whether

they recognize the brand names, they cannot reasonably answer the question about the

quality of products that are unavailable.

(B) There's no difficulty in categorizing the responses to questions; on the contrary, the

survey results can be organized neatly into two rankings.

(C) It's never stated that the survey requires respondents to give up their anonymity, so

there's no evidence that (C)'s principle is violated.

(D) The survey doesn't ask many questions about a single product, but two questions

about 400 products.

(E) The survey abides by (E); the respondents are asked about their personal opinions of

the products in question, so how could they get the answer wrong?

"¢ If you don't recognize the principle directly, use the process of elimination.

Concentrate on the violation the survey is supposed to have committed: an

unmanageable number of categories (B), violating anonymity (C), asking ten

questions about one product (D), respondents' fear of being wrong (E). Even if you

had trouble following the stimulus, all of these are pretty clearly inapplicable.

Whats another question in Option 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."

Also how does another question matter? Because original explanation says that the respondents are essentially "not well" informed about the foreign products and hence they should not be questioned about it. How does another question in the survey matter in this explanation?

Guys can anyone give a decent reason why A is not right.
