Fred worked as a zoo keeper at a local zoo and was responsible for an event called the "Chimpanzee Party" that will be held a few days from now. As the name suggests, the party was for the chimpanzees in their zoo. Visitors could interact with the chimpanzees during the event and enjoy the party.
Of course, the event was only possible because the chimpanzees in Fred's Zoo were well-behaved. But to ensure that non of the visitors would be harmed, Fred and the other zoo keepers had to make some arrangements. Moreover, rules that the visitor must strictly follow are implemented to avoid any harm befalling the animals. For example, only the zoo's food would be allowed to be given to the chimpanzees.
Although strict requirements were put into place, the zoo still believed the event would be successful. And they're right. Even before the event started, hundreds of visitors already made reservations, ensuring that the zoo would be packed with people during the event.
Finally, the awaited day arrived. One by one, visitors entered the venue and started interacting with the chimpanzees. For their part, the chimpanzees are well-behaved thanks to the effort of the staff, who spend a lot of time training the animals.
Before long, the event ended, and everyone, the visitors, the staff, and the chimpanzees seemed to have enjoyed the party.
