No, it is not 'trivially' true. It is a fairly precise response to the question that solicits clarification of just what is being asked.

The querant can then refine their question to allow a meaningful reply, assuming their apparent ignorance is actually treatable. Note that 'ignorance' is not used in its pejorative sense but in a simple descriptive sense.

I like merlyn's response. It offers the beginning of a dialog that can lead to more than a simple answer to the poorly worded question.
