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.
