On PT110.S2.Q23, I had each conditional, contrapositive, and chain mapped out correctly; however, I still got the question wrong. I watched the video explanation, and I'm still stumped. I can't understand how any of the answers are correct, because they all seem wrong. The correct answer is E, and I see where ONE of the conditions (inspires revulsion -> threatening) is met; however, the answer choice includes the word "and," so, it seems like both conditions would need to be met? But the second condition (physically dangerous -> threatening) is NOT met--the correct answer explicitly says the monster is NOT physically dangerous. Can someone help me understand why E is still correct?

The stimulus says that a monster is threatening if it's physically dangerous, OR if it inspires revulsion. This means either one is enough to satisfy the conditions to be threatening. E is simply talking about a special kind of monster that is not that is not physically dangerous, but still inspires revulsion. Since the psychological factors are irrelevant, you can re-frame answer choice E as "All monsters that are not physically dangerous BUT who inspire revulsion, are threatening". This is true.
