I recently asked this question on this meta. However, it was marked as the duplicate of this question. But the latter question has had no answer and even less number of comments than the first one. In this case, is it advisable to mark my question as the duplicate of the second question?
Here's the thread on Meta.SO that posted right after an automated check was implemented that any proposed "duplicate" in closing (as duplicate) requires an Answer either Accepted or up-voted:
Note that the suggested feature (reversing the restriction as to closing as duplicates) was ultimately "status declined".
Apparently this automated restriction only applies to the subject matter sites, not the meta discussion ones (which makes sense to me). In the context of discussing policy and site management, flexibility in judging whether timeframes justify a clean-slate makes sense (to me). To that extent I'm in favor of not having the automated restriction on Meta sites. It is possible to raise valid meta Questions that go unanswered but gather support or not as reflected in voting on the Question itself.
Particular instances are then debatable, and it certainly makes sense to want to preserve the better commented of two duplicates, given that neither is Answered. Some of that purpose would be served by linking the two Questions.
