How he said "DIFFICULT TO BELIEVE???" during A, was exactly how my brain read it. Immediately when I read that I crossed A out. LOL

I really need to read the question prompts thoroughly instead of skimming, cause question 5 was a MBF instead of a MBT..... :(

I have a question on conjunction and disjunction. I understand how the stim had a conjunction (fish and birds), but I seem to be confusing how the answer D became a disjunction (/fish OR bird). I understand the negation parts of it all, just a little confused why or how do you know D is a disjunction. indy -> /fish OR bird.
