请问一道逻辑题

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


Manhattan的，答案是c。。。 然后分析中一上来就说，这个是个example 完全没看出来是个example啊...求解

rights.

formal education is one example of how citizens can learn how to excercise. 估计是考这个点吧，只能勉强这么理解了。不过这个题目是挺绕的，Manhattan的RC和逻辑题目有点难的，我做的时候也很吃力
