Question

Citizens cannot impact government decisions on public policy.

Answer 1

This is definitely false. According to the 1st amendment, people have the right to petition, which means we can change things.

Answer 2

This is a definite false. Tens of thousands of men and woman participate in the petition's of parliaments and ministers, who join interest groups/corporations and community movements. So we in fact do have somewhat of an impact on our public policy's.

Hope I helped. :)
