KudoZ: asking

I am not sure whether a question should be classified as non-PRO or PRO. What is the difference?

While there may be no way to draw a clear-cut line, the following definition has been adopted:

Non-PRO questions are those that can be answered by any bilingual person without the aid of a dictionary. All other questions are PRO.

When applying the above definition, detach yourself from your own background/specialization and think of a -hypothetical- randomly selected bilingual person. Is it likely that this person would be able to produce a good translation of the term or phrase in question (and in the particular context shown) from the top of his/her head? If not, it is a PRO question.
