Although the authors generally disagree about the roles men and women should occupy, both Tocqueville and Mill share the idea that gender equality is one small part of a societal shift toward equality in general. This can be seen in the first paragraph of Passage 1, where Tocqueville explains that raising woman to be "more and more the equal of man" is part of the overall "social changes which bring nearer to the same level the father and son, the master and servant," and in the first paragraph of Passage 2, where Mill writes that "mankind have outgrown" the state of inequality and "now tend to substitute, as the general principle of human relations, a just equality," with gender roles being the last of these relations to undergo such a shift.
Choice B is incorrect because although in Passage 1 Tocqueville argues that there are costs to treating men and women the same, in Passage 2 Mill characterizes gender equality as a source of benefits only. Choice C is incorrect because neither author considers changing gender roles in terms of economic ramifications, focusing instead on questions of fairness and justice and the fulfillment of people's potential. Choice D is incorrect because Mill does not discuss the issue in terms of American democracy, though Tocqueville does.
