Phrase I fail to understand Forum

I am working through prep test #13, Section 4 (logical reasoning/question 22)

I come across this question

(Survey asking to rate 400 famous brands, but only 27 brands are available in nation, recognizing only certain brands those are the only available brands in the country)

I fail to comprehend the full meaning of answer choice A)-> The right answer.
"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."
--> just what does respondents who make a particular response to another question in the same survey mean? Should I worry about this at all? or should I just ignore this question because is just awkward wording and probably will never encounter stuff liek this again.

Thanks.

Didn't look up question but I remember it from awhile back so bear with me:

I believe the question asks for a principal? In this case a principal that weakens it? Well what the answer is saying is you should ask certain people a question "about the brands" if they answer a certain way about another question "in this case they answer no to have you heard of the brand or from its country or whatever"

Get it? If I answer that yes I've never heard of the brand, you shouldn't proceed to ask me what I think about it
