Help Please

Hello, I'm struggling to grasp this question. I diagrammed the passage as: IA and PP==>OP contrapositive: not OP ==> not IA or not PP. IA==> AFG not AFG ==> not IA. I want to say that any answer choice that says "immoral actions are not accompanied by feelings of guilt" contradicts the second principle and is thus the answer. But choices A and D say that.... I went through the previous questions on this message board but I'm still confused. Thank you for your help!

Hi @Rebecca-Alvarado, thanks for your post. Answer choice (A) and answer choice (D) actually say two different things. Only answer choice (A) says some immoral acts . . . are not accompanied by feelings of guilt. Answer choice (D) only talks about "actions that *are* accompanied by feelings of guilt."

Answer choice (A) is the one that contradicts the stimulus, and thus the one that "must be false."

Hope this helps. Please let us know if you have any additional questions.
