Question

What could be the reason behind the unique seating arrangement?

Answer 1

As the gravitational force of the moon is 1/6 that of the earth, the children would have found it difficult to sit on chairs outside the artificially-maintained settlements. They would also have to wear space suits. Therefore they were made to sit inside the tents. The circus was going on outside the tent because the gravitational force of the moon was making high jumps and long jumps very easy for the gymnasts and thrilling for the spectators.
