The correct response is: Citizens become more active in the body politic, which leads to greater involvement in political activity.
The Servicemen's Readjustment Act (GI Bill) not only provided educational benefits to veterans but also empowered them to pursue higher education and vocational training. As a result, many returning veterans became more engaged in civic and political activities, contributing to a more informed and active citizenry. Education typically fosters greater political participation, leading to increased involvement in democratic processes and civic responsibilities.
