It highlights that petitioning allows citizens to directly express collective concerns to the government, influencing democratic processes and agendas.

The passage argues that while elections are periodic, petitioning maintains a continuous dialogue necessary for democracy to truly reflect the people's voice.
Considering this analysis, the option that most accurately summarizes the passage is: "Petitioning has been important to democratic functioning, as it supplements the electoral process by enabling ongoing engagement with the government." This option encapsulates the essence of the passage by emphasizing petitioning as a complement to elections, facilitating constant interaction between the populace and the government.
