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

### Instruction:
At a zoo, four friends - Emma, Olivia, Liam, and Noah - watch a monkey steal a banana from a visitor. The monkey runs up a tree and places the banana on a branch before climbing down and running off. A bird swoops in and takes the banana from the tree branch, flying over to another tree and dropping it into a nest. Afterward, a squirrel retrieves the banana from the nest and buries it near the base of the tree. Which tree do the friends believe the banana is located at, and how do their beliefs change as they witness these events?

Provide a brief response.

When Emma, Olivia, Liam, and Noah initially see the monkey steal the banana and place it on a branch, they likely believe that the banana is in the tree where the monkey left it. Their belief would be based on their direct observation of the event.

As the friends continue to watch, the bird's action of taking the banana from the branch would shift their belief to thinking that the banana is now located in a different tree, the one where the bird drops it into a nest. This change in belief is due to them witnessing the bird's actions and the new location of the banana.

Once the squirrel takes the banana from the bird's nest and buries it near the base of that same tree, Emma, Olivia, Liam, and Noah would then update their belief to think that the banana is at the base of the second tree, where the squirrel buried it. This again would be the result of them observing the squirrel's actions.

Throughout these events, their beliefs about the location of the banana change as they watch each animal move the banana from one place to another. Their current belief at any given moment is based on the most recent action they have observed involving the banana.
