Based on prior knowledge, marital status can be an important factor in determining a person's income. Let's analyze the relationship between the marital-status feature and the task of whether a person earns more than 50000 dollars per year.

Analysis:

- Never-married: People who have never been married might have lower chances of earning >50000 dollars per year due to a potentially lower level of financial stability.
- Married-civ-spouse: This category includes individuals who are currently married to a civilian spouse. It is possible that being in a stable marriage might increase the probability of earning >50000 dollars per year.
- Widowed: Being widowed might have an effect on income, but it is difficult to predict.
- Divorced: Divorced individuals might have varying income levels, so it is hard to determine if they are more likely to earn >50000 dollars per year or not.
- Separated: Similar to the divorced category, it is hard to predict if separated individuals are more likely to earn >50000 dollars per year or not.
- Married-spouse-absent: This category includes individuals whose spouses are absent, which might have effects similar to divorced or separated individuals.
- Married-AF-spouse: This category includes individuals married to spouses serving in the Armed Forces. It is difficult to say if this marital status alone determines income level.

Based on this analysis, we can generate the following dictionary:

```json
{
	"no": ["Never-married"],
	"yes": ["Married-civ-spouse"]
}
```

In this case, we only include the marital-status categories that have a clear relationship in predicting the target variable of earning >50000 dollars per year.
