You lost me on the explanation why D should be eliminated You stated D is a valid positive argument structure but we are looking for a similar contrapositive with the passage like we saw in answer choice A.

Great question. In example 2, (D) says If Mark were a good cook, he
would not put cinnamon in the chili. Therefore, the fact that he is
not a good cook shows that he put cinnamon in the chili.

GC - >/CC
/GC - >CC

This is an invalid argument. The stimulus of the question gave us an
argument with a valid contrapositive argument structure. (D) is giving
us a conditional statement and just negating both the sufficient and
necessary conditions. This is invalid logic.

In order for (D) to have been correct, we would have needed it to say

GC - >/CC
CC - >/GC

That is what the valid contrapositive structure for (D) would look
like. Since that's not what (D) actually says, we can eliminate this
answer choice.

Does that make sense? Let us know if you have any questions!
