Question：The overriding feature of good quality information is that the information must be:
A. Relevant.
B. Completely accurate.
C. Concise.
D. Produced quickly.
The correct answer is: Relevant.
解析：Information must always be relevant to a purpose when it is provided or there is no point in having it - it has no value.
Information should often be accurate, but accuracy is not always possible - especially, for example, in the case of forecasting information.
Information should often be short and concise, but there are times when detail is needed - for example, think about legal information and the lengthy detail that solicitors often need to draw up contracts.
Good quality information must be timely which means that is ought to be available in time for when it is needed. This doesn't necessarily mean that it has to be to the detriment of other characteristics.
