Choice B is the best answer. In Passage 2, Thoreau says that if a law "is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law" (lines 64-66). It is clear from Passage 1 that Lincoln would reject this stance, as he says individuals should never break the law ("Let every American... swear... never to violate in the least particular, the laws of the country," lines 1-4) and should wait for a bad law to be repealed ("bad laws, if they exist, should be repealed...still while they continue...they should be religiously observed," lines 29-32).
Choices A and C are incorrect because in Passage 1, Lincoln is absolutely clear that all laws"should be religiously observed" (line 32); he does not describe anyone's suggestion to break the law as either excusable (choice A) or honorable (choice C). Choice D is incorrect because it is not supported by the passage, as Lincoln does not discuss the core principles of the Constitution in Passage 1.
