The question is described here. It is PT 56 Section 2 Question 23. I was stuck between D and E and eventually chose D. I have read that it is incorrect because it is an illegal reversal, I just do not understand how.
I basically wrote it out like /Intervention -> Extinct and contraposed that as /Extinct -> Intervention which led me to answer choice D. What did I do wrong?
