The second sentence of the Para 2: “Prior to Kerber’s work, educational historians barely mentioned women and girls; Thomas Woody’s 1929 work is the notable exception.” So, E “atypical in that it examined the education of girls” is correct.
选B的理由又是什么呢?根据上一句话,作者在educational history中强调的是barely mentioned women and girls,不是concentration在哪个时期吧?
