Hi @izyat,izyat June 13, 2019
Sorry, I meant to say that in the video explanation of the question, we figure out that the original passage presents a flawed argument, however when we come to the conclusion that choice E is correct at the end of the video, I believe the video tells us that choice E employs a valid contrapositive argument structure. So if the original passage is flawed, how could the correct answer follow a valid contrapositive structure?
