Last weekend, Mai Phương had an exciting day at the amusement park. She started by eating a big meal with her family at a nice restaurant inside the park. After lunch, they decided to go bowling, and Mai Phương won the game with the highest score. Later, she was brave enough to ride the roller coaster, even though it looked very scary! Finally, they walked through a beautiful area of the park filled with tall trees and wood sculptures. It was a day full of fun and adventure.
Question: What were the wood sculptures surrounded by?
