Can a participant or team choose from multiple answers for a Mission, with each answer unlocking a different Mission?
At this time it is not possible to have different answers to a Mission unlock different Missions.
Can I make a Mission unlock only if the participant or team submits the correct answer?
Yes, this is possible if you make the Mission a Text Mission or a GPS Mission as they can require specific answers. At this time this is not possible with Camera Missions.
If it is a Text Mission you will want to make sure you include the correct answer in the "Accepted Answers" field. For more instructions on how to set up a text Mission, please refer to this article.
