If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which room arrangement made participation difficult?
What display or audio issue affected you?
What setup change would help?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: participants at the back cannot read the display.
2. An affected display or audio moment identifies a practical room barrier to following the activity. Review the setup and available alternatives, without treating individual feedback as a complete equipment or accessibility assessment.
3. Turn the requested improvement into a testable next step. One illustrative action is: test display readability before the next session.
