Experiment designers should be able to:

• add a new stage to the experiment prior to the PreDiscussionInstructions stage that will play this video: https://youtu.be/dKggA9k8DKw?si=GH9dwl42bN_NoixT
• add a new prompt question to PreDiscussionInstructions above the submit button that asks what the people in the video build together, with options "a bar", "a couch", "a clock", or "a tower of blocks".
• make the submit button only display once the new question is answered
