Answer: The statement that paraphrases the authors’ argument is "Women’s lack of political rights is the root of their troubles."
Explanation: Just to elaborate a little on the answer, it can be added that in this excerpt from the 19th book A History of Women’s Suffrage the authors are arguing that women had been taking an incorrect approach when attempting at putting an end to the way they had been socially and politically treated. Instead of identifying that by not being allowed to make laws that acknowledged and protected their rights they were experiencing all those "wrongs and oppressions," they simply kept complaining and asking society to correct those grievances.
