参考答案

正确答案：D
解析：文章第三段第一句话就是本段的主题句，其后介绍的都是有关于the 55 men framing the Constitution的情况，因此可以断定[A]错误，而[D]正确。[B]和[C]中所述与第四段最后一句“But the group also contained some real nonentities, including a military man who had been court-martialed for cowardice during the Revolution, some who contributed nothing to the debate, and some who were not quite able to follow what was being debated”相矛盾。
