Answer:
A. give voters information about important events.
Step-by-step explanation:
Most people, couldn't keep up with all the information regarding foreign and domestic issues due to the jobs that they have to handle every day.
While the members of the congress analyze these problems on day to day basis. So, they're expected to have a deeper understanding over these issues and create a way to deal with it on behalf of the people.
This is why when members of congress made a legislation, they're expected to somehow provide information to potential voters regarding why t's made and how the new legislation would address the specific issues.
