Answer:
a. a responsibility that all adult citizens share
Step-by-step explanation:
The right to vote is crucial to protect and assert our rights. We build our democracy with votes. We express what we think and by empowering our officials to act we promote our collective interests; the power of the vote keeps our officials accountable. If only a few people voted, elected officials would likely give less weight to the interests. Each person’s vote makes our democracy more representative of the will of its citizens and though one vote may not make a difference, in close local elections, small numbers of votes can be decisive.
