Based on my prior knowledge, I can assume the feature "persons, capacity in terms of persons to carry" is related to the target variable "decision to buy this car" as follows:

- If the capacity is for 2 persons, it is more likely that the decision to buy the car would be rated as "acceptable" or "good".
- If the capacity is for 4 persons, it is more likely that the decision to buy the car would be rated as "good" or "very good".
- If the capacity is for more than 4 persons, it is more likely that the decision to buy the car would be rated as "unacceptable" or "good".

Based on this analysis, I will create the dictionary:

```json
{
	"unacceptable": ["more"],
	"acceptable": ["2"],
	"very good": ["4"],
	"good": ["2", "4", "more"]
}
```
