If I understand the above comment correctly, I have the same problem:
that is:
multiple choice:
I give 2 possible correct answers when creating a question:
Say, correct articles for “in … Zimmer”: both “das” and “die” are correct
AND
I would expect only one answer be marked…
yet when student puts a check to (say) “das”, program says it is incorrect, as not both “das” and “die” were marked.
But I did not want both marked! – one of the two possible right answers should be accepted as “correct”!
Is it possible with setting the quiz question?
