Choice B is the best answer. In Passage 1, Lincoln asserts that citizens of the United States should never break the laws of their land, for any reason, because to do so undermines the nation's values. This is clearly demonstrated when he says, "let every man remember that to violate the law, is to trample on the blood of his father, and to tear the character of his own, and his children's liberty" (lines 9-12,"let...breathed by").
Choice A is incorrect because Lincoln says that bad laws"should be repealed as soon as possible" (line 30,"should...possible"), not that breaking the law would slow their repeals. Choice C is incorrect because Lincoln says that "there is no grievance that is a fit object of redress by mob law" (lines 36-37,"There...instance") but doesn't argue that breaking the law will lead to mob rule. Choice D is incorrect because in his speech Lincoln doesn't discuss divisions between social groups.
