# If the answer to question B answers question A, should question A be considered a duplicate?

The question Fields and proper subfields., which asks if a field can be isomorphic to a proper subfield was closed as a duplicate of Algebraic closure of $\mathbb{C}(x)$ is isomorphic to $\mathbb{C}$.

Ofcourse, (the answer to) the second question answers the first, but I don't think this should be considered a duplicate (at least not of the second one). In particular, someone coming up with this question when starting to study fields, might not even recognize that the second question gives an answer.

Edit: I realize that the general question in the title is likely unanswerable (other than "maybe; depends on the questions"). My concern is actually with the specific questions.

• Magdiragdag: If you want to ask about one particular instance (rather than discuss the question in general) you should also add (specific-question) tag to indicate this. (See the tag-wiki for more information about this tag.) – Martin Sleziak Jan 10 '14 at 10:41
• @MartinSleziak Ok, thanks. I'll do so. – Magdiragdag Jan 10 '14 at 11:52
• As long as the closed question is not deleted, the next person asking the same thing has a chance of finding it. Note: in my opinion, closed questions should, in many cases, not be deleted. – GEdgar Jan 10 '14 at 14:22
