Could you please show me how draw diagram of the reasoning method on the stimulus? I don't think this is not a sufficient and necessary condition. Then, how we can approach this kind of question? Many thanks,

    Alright, we know that: "good things cause no harm at all," P1: GT ==> not H H ==> not GT So, since W can be harmful P2: H Using the contrapositive of P1, we can validly conclude that wealth is not a good thing. C: not GT This is a valid argument that is invoking the contrapositive of our general principle. Answer choice (A) has a similar pattern of reasoning. "No one in the chess club loves to golf." P1: CC ==> not LG LG ==> not CC We know that Alex love to golf. P2: LG Using the contrapositive of P1, we can therefore, conclude that Alec is not in the chess club. C: not CC Hope that was helpful! Please let us know if you have any other questions.
