Sentences in the review queue are sorted by most votes. This makes it most likely for sentences to get approved quickly instead of spreading out votes all over the review queue.
Could you share a link to where those sentences are from? I see it marked as source “Wikipedia Public Domain Dump files”. If these indeed are Public Domain, then all good. However if these are coming from normal Wikipedia articles, they might not indeed be Public Domain. We have a process for these cases using the Sentence Extractor, which makes sure that we only extract 3 sentences per article maximum (legal requirement).
I see what you did there and this deserves its own shoutout, well done!
Thanks!
