I'm guessing that the 68% who thought that the Pacific is getting bigger were thinking of sea level rise rather than continental drift.

No, I was thinking of plate tectonics, just assumed .. I guess it's a divergent plate boundary(?) rather than subduction. My first thought was magma/underwater volcanic activity/gasses. - I guess the Mariana Trench is a subduction zone, which makes sense in hindsight.

I don't really recall what little school focus was on geology, I don't remember the basic theory :/ If anyone has a brief summary please provide it

How could only 80% get the right answer? It requires a level of knowledge I would expect from a 2 year old.

It's easy to overthink things on a quiz like this because you often feel like you're being tricked. I usually think of insects as animals, but hesitated for a second, thinking there was some scientific differentiation relating to having a thorax or something.

I once had an argument with someone who thought birds weren't animals. It was on Facebook and a lot of people were saying the same thing...

I can't answer for them, but if you're at a level of understanding of biology where you don't know insects are animals, you probably don't have the possible categories defined at all.

For you and me, it's "well insects obviously aren't plants, fungi, or microscopic, so naturally they're animals", but for SouthKorea it might be more like, "idk, bugs?"

Outside of biological settings the examples of animals we think about are almost always chordates, and more often than not mammals.

Wow. I would have thought more people would know that pandas are bears??? Perhaps people overthink it and think it's a trick question. After all, koala bears aren't really bears, and people love to put that on quizzes.

The problem is that for decades there was debate about the proper classification of the panda. I remember as a kid in the '80s and '90s being taught that they weren't true bears, but were actually more closely related to raccoons. It's only within the past ten years or so that genetic analysis has definitively confirmed that they are, in fact, part of the bear family.

"The percentage of Neanderthal DNA in modern humans is zero or close to zero in people from African populations, and is about 1 to 2 percent in people of European or Asian background"

Different dictionaries say both are ok, that octopi is older but octopuses is more commonly used.

Octopi shouldn't be OK at all because the correct plural form, as Cycloethan said, is octopodes.
