Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
In a library, there are four students: Mia, Noah, Ava, and Liam. They all have different colored bookmarks: Mia has a green one, Noah has a blue one, Ava has a yellow one, and Liam has a red one. Mia puts her book on the table with her green bookmark inside before going to the restroom. While she's away, Noah accidentally spills water on the table, causing the bookmarks to get mixed up. When they try to fix the situation, Ava mistakenly puts her yellow bookmark in Mia's book. What will happen when Mia returns from the restroom? How might each student react?
Respond briefly.

### Response:

When Mia returns from the restroom, she will likely notice that the bookmark in her book is not her green one, but rather Ava's yellow one. This will indicate to her that the bookmarks got mixed up while she was away. Mia may ask the other students what happened and why her bookmark is not in her book.

Noah, knowing that he caused the initial chaos by spilling water, might apologize to Mia for the accident and explain that in the process of cleaning up and sorting out the books and bookmarks, a mistake was made. He may feel guilty for the mix-up.

Ava, who put her yellow bookmark in Mia's book by mistake, may also apologize to Mia for the confusion and offer to help sort out whose bookmark is whose. She might feel a bit embarrassed for adding to the mix-up.

Liam, who hasn't directly contributed to the mix-up but is present, might assist in figuring out where the red and blue bookmarks are and help return Mia's green bookmark to her.

Each student will probably engage in a conversation to identify their own bookmarks and to rectify the situation by exchanging them back to their rightful owners. The mix-up could lead to a brief moment of shared problem-solving among the students.
