Indeed! questiontext of both records in mdl_question where id=81890 and id=70191 are the identical. But in mdl_question_answers there are five records where question=81890 whereas there are only two where question=70191.
My question is, how did the teacher create such an anomaly? Is it possible that she created a "new" question, which by chance identical to the dot to an old question, but the possible answers were not?
I don't think the loss of such a "quick question" is a big deal. Is it advisable to purge it in the database? Is there a safe way? She has close to 10 courses, where she imports activities, resources and quizzes in all directions!
