“Each number here corresponds to a staff member who will supervise the children’s hand movements during the competition to ensure that there are no violations.”
After explaining all this, the staff member asked, "Does anyone have any other questions?"
Everyone: "..."
This series of actions has completely silenced everyone.
Seeing that no one spoke, the staff member said, "Alright, you can enter now. The last two rows are for parents. Please be careful when you go in and don't make loud noise!"
