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

### Instruction:
Mary has two identical jars filled with cookies. She labels one jar "chocolate chip" and the other "oatmeal raisin." Nancy comes into the room and swaps the labels without Mary noticing. Then, Olivia enters and takes all the cookies from the chocolate chip jar (now labeled oatmeal raisin) and replaces them with peanut butter cookies. Finally, Mary, Nancy, and Olivia sit down to enjoy some cookies. What does each person think about the contents of the jars?

Provide a very brief response.

### Response:

Mary believes that one jar contains Chocolate Chip cookies and the other contains Oatmeal Raisin, since she is unaware of any changes. Nancy knows that the labels on the jars have been switched, so she thinks the jar labeled "Chocolate Chip" contains Oatmeal Raisin cookies and vice versa. However, neither Mary nor Nancy knows that Olivia replaced the cookies in the jar now labeled as "Oatmeal Raisin" with Peanut Butter cookies. Therefore, Nancy will be surprised to find Peanut Butter cookies instead of Oatmeal Raisin. Olivia knows that the jar labeled "Oatmeal Raisin" contains Peanut Butter cookies, because she made the switch, but she would also believe that the other jar, now labeled "Chocolate Chip," contains Oatmeal Raisin cookies since she is not aware that Nancy had previously swapped the labels.
