If this is set to True, don't display results of the poll to the user.
Notes:
If you change an answer's text, all students who voted for that choice will have their votes updated to
the new text. You'll want to avoid changing an answer from something like 'True' to 'False', accordingly.
If you delete an answer, any votes for that answer will also be deleted. Students whose choices are deleted
may vote again, but will not lose course progress.
{% if multiquestion %}
Questions must be similarly cared for. If a question's text is changed, any votes for that question will remain.
If a question is deleted, any student who previously took the survey will be permitted to retake it, but will not
lose course progress.
