As the United States demonstrated during its early development, it is
not enough for citizens simply to have rights; the successful
functioning of a democracy requires that they also know how to
exercise those rights. Access to formal education was one necessary
component that helped the U.S. citizenry learn how to exercise its
rights. Therefore, in order for a democracy to function successfully,
its citizens must have access to a formal education.
The author develops the argument by
(A) using an analogy to establish a precedent for a planned future event
(B) illustrating differences in the requirements for the functioning of a
democracy depending upon the democracy in question
(C) introducing an example that illustrates a common principle
(D) forming a hypothesis that explains apparently contradictory pieces of
evidence
(E) supplying an alternate explanation for a known phenomenon
