Choice B is the best answer. Passage 1 argues that the government is sacred (lines 3-6,"we...caution") and that no person should interfere with it (lines 6-9,"that... solicitude"). Passage 2 argues that people have the right to make changes to their government: "The circumstances of the world are continually changing, and the opinions of men change also; and as government is for the living, and not for the dead, it is the living only that has any right in it" (lines 73-76,"The... in it").
Choices A, C, and D are incorrect because they do not identify the main purpose of both passages.
