I recently got access to the "Low quality posts" review part. In the queue there was this, one of these obvious [homework] questions. It was flagged as "low quality" because of its length and content, which I can agree on.
I tried to find an option how to deal with it. It certainly did not "Look good", I could not "Edit" it, to improve it, the options for "Recommend close" did not fit either. What to do in such a situation? I assume this happens more often. I didn't do anything and @martini chose "Looks good" then.
To me this meta question on how to handle down-voted answers with "low quality" seems related but not quite the same.
