The author mentions all of the following as evidence that the revolutionary colonists were more intent upon expanding their roles in the old power order than in creating a new one EXCEPT_____.

解析：细节题。解题点在文章第三段。文章提到“those ruling in 1770 also held power in 1790，while the Parliament，a bicameral legislature，was replaced by the Congress，another bicameral legislature and the King supplanted by a President”，说明革命后的体制与革命前很像，因此选项B正确；由“only propertied white males had suffrage，both before and after the war”知，战争前后都只是有钱的白人男性才有选举权，故选项D正确；由“the economic system was not altered，nor was the class structure，except toforbid a nobility that in any case had only a nominal existence in the colonies before the war”知，对于社会阶级的改革只限于取消了贵族特权，故选项C正确。A选项中的商业改革原文中没有提及，所以正确答案是A选项。
