First Paragraph:
The new school of political history that emerged in the 1960s and 1970s sought to go beyond the traditional focus of poitical historians on leaders and government institutions by examining directly the political practices of ordinary citizens. Like the old approach , however, this new approach excluded women. The very techniques these historians used to uncover mass political behavior in the nineteenth century United States - quantitative analyses of election returns , for example - were useless in analyzing the political activities of women , who were denied the vote until 1920.

Question:

A : They involved the extensive use of the biographies of political party leaders and political theoreticians.

B: They were conceived by political historians who were reacting against the political climates of the 1960s and 1970s.

C: They were of more use in analyzing the positions of United States political parties in the nineteenth than in analyzing the positions of those in the twentieth century.

D: They were of more use in analyzing the political behavior of nineteenth-century voters than in analyzing the political activities of those who could not vote during that period.
