Influenced by the view of some twentieth-century feminists that women's position within the family is one of the central factors determining women's social position, some historians have underestimated the significance of the woman suffrage movement. These historians contend that nineteenth-century suffragism was less radical and, hence, less important than, for example, the moral reform movement or domestic feminism—two nineteenth-century movements in which women struggled for more power and autonomy within the family. True, by emphasizing these struggles, such historians have broadened the conventional view of nineteenth-century feminism, but they do a historical disservice to suffragism. Nineteenth-century feminists and anti-feminist alike perceived the suffragists' demand for enfranchisement as the most radical element in women's protest, in part because suffragists were demanding power that was not based on the institution of the family, women's traditional sphere.
The passage provides information to support which of the following statements about the historians discussed in the passage EXCEPT
A. They rely too greatly on the perceptions of the actual participants in the events they study.
B. Their assessment of the significance of nineteenth- century suffragism differs considerably from that of nineteenth-century feminists.
C. They devote too much attention to nineteenth- century suffragism at the expense of more radical movements that emerged shortly after the turn of the century.
分析：A错由于这些historians被20新世纪的女权运动者危害了，而并不是十九世纪的女权运动者。c错由于客观事实恰好反过来，她们感觉suffrage 后边的movement更radical和更important。因此她们不容易pay too much attentions 在suffrage上。B对由于historians是立在20新世纪的女权主义者视角讲的，因此和那时候十九世纪的女权主义者想的不一样。
