Earlier I saw a first post come through the review system titled "Are mathematical articles on Wikipedia reliable?" Now, since I'm genuinely reviewing and not thinking that the system is throwing fake situations in my face (It shows a total score of 0 for the question and maybe 1 comment) I click to flag as a duplicate since recently there was a successful question on the same topic.
Apparently this was the question I thought it was duplicating and I immediately failed the audit. However, if such a question were to legitimately come through the system, flagging as duplicate would be the correct action, right? I think either a.) we should not have famous questions as audit material, since the audit system makes it look like a distinct (but still duplicate) question or b.) allow us to flag as a duplicate, because that's the most realistic action to take.
Here is the failed review.
