Answer:
<h2>By participating in a town hall meeting for legislators.</h2>
Explanation:
The options of these question are:
- by agreeing to be interviewed on a local radio station
- by participating in a town hall meeting for legislators
- by talking to family members about health issues
- by making an appointment with a family physician.
As you can see, among the options, the second one is the one that makes sense, because an interview on a local radio station won't change anything about community health issues, neither talking to family members about it, neither making an appointment with a family physician.
Those that can actually impact and change community issues are legislators, the ones that create and manage laws, because they works towards a social-general benefit.
Specifically, a town hall meeting or just town halls, comprehend the event where local and national politicians meet with the people, to heart their principal topic of interest, mainly, about specific issues in different communities.
Therefore, the right answer is the second choice.
