A vs. C

I am confused on the differences between the answer choices A & C. Could I see these diagrammed along with an explanation for the differences as to why one is right and the other wrong?

Hi JessieH,

Lets look at A, we could diagram it as

If TO -> FE and HQE
FE and TO, so, HQE

C could be diagrammed at

If S and W2 -> D
S and D, so W2

The difference here is that in A there are two parts to the necessary condition, and in C there are two parts to the sufficient condition.
