This question already has an answer here:
Today was my first attempt at flagging a question as a duplicate. When I stepped through the flagging wizard, I noticed the comment below the "duplicate" choice that says "This question has been asked before and already has an answer."
Does flagging a question as a duplicate really require that the original must have an answer?
This answer on meta says that it is not so, and that only the content of the questions is relevant. But then, why does the flagging wizard contain the comment quoted above? Am I too strict and should just accept the comment as a guideline instead of as a hard rule?
If it is of any interest, the questions I am talking about can be found here, here and here. At the time of writing, none of the questions has an accepted answer, or an answer that seems to solve the problem.
