Based on prior knowledge, the relationship feature can be a strong indicator of whether a person earns more than $50,000 per year.

Analysis:
- People who are "Husband" or "Wife" might have a higher likelihood of earning more than $50,000 per year as they are likely to be in a married household where two incomes contribute to the total earnings.
- Individuals who are "Unmarried" may have a lower likelihood of earning more than $50,000 per year as they may not benefit from the financial advantages that come with marriage.
- People classified as "Own-child" and "Other-relative" are likely to be dependents and may have a lower probability of earning more than $50,000 per year.
- The "Not-in-family" category does not provide enough information to determine the likelihood of earning more than $50,000 per year. The relationship of the individual to others is not specified, so it is hard to predict the impact on the income level.

```json
{
	"no": ["Own-child", "Not-in-family", "Other-relative"],
