The correct options for how people can provide input in government to protect their interests are:
- getting involved with the community
- by voting
- sitting on a jury
Therefore, the most direct answers would be "getting involved with the community" and "by voting." Sitting on a jury can also be seen as a form of civic engagement, but it's more specific to the judicial process rather than direct governmental input. The statement "the people are not able to provide input in government" is incorrect.
