Thanks for sharing this. I got all 4, but none of which were so obvious that I had absolutely no doubt. I had to reason about all of them. And I'm absolutely confident that a LOT of perfectly reasonable people can potentially score zero on this test.

Thanks for sharing. I am curious which of the four quiz questions you failed—to me they looked relatively easy to tell apart, but I follow the progression of this tech very closely.

4/4 for me, but probably only because I knew about that tear gas incident, and that snake was way too loud and they don't tend to move like that unless it's sand.
