The traits that can make a person a good voter include:
- **interested in news**: Staying informed about current events and issues is crucial for making informed voting decisions.
- **understands government**: A good understanding of how government functions can help voters make choices that align with their values and goals.
The other options (membership in a political party, owning property or a business, paying federal taxes, and serving as a volunteer or in the armed forces) may reflect various aspects of civic engagement or social responsibility, but they do not necessarily make someone a better voter in the context of being informed and making educated choices during elections.
