To test this, you need to
1. create a question with the check-box turned on,
2. edit the question, and turn off the checkbox.
3. re-edit the question, to see whether the fact that the checkbox was off has been saved correctly.
It is sufficient to test this with a matching question. You need to test these three checkboxes:
a. "Show the number of correct responses" under Feedback "For any partially correct response".
b. "Clear incorrect responses" under any hint.
c. "Show the number of correct responses" under any hint.
