```json
{
	"no": ["no"],
	"yes": ["yes"]
}
```

Based on the given feature "default" and the task of determining whether a client subscribes to a term deposit, we can conclude the following:

- If the value of the feature "default" is "no", then the client does not have any credit in default and is less likely to subscribe to a term deposit.
- If the value of the feature "default" is "yes", then the client has credit in default and is more likely to subscribe to a term deposit.

Since the given feature "default" is a categorical variable with two possible categories "no" and "yes", we can create a dictionary with two lists indicating the possible values of the feature "default" for each target class:

- For the target class "no", the possible values of the feature "default" are ["no"] indicating that clients who do not have any credit in default are less likely to subscribe to a term deposit.
- For the target class "yes", the possible values of the feature "default" are ["yes"] indicating that clients with credit in default are more likely to subscribe to a term deposit.
