The sushi one I first tried nigiri because the way the clue is worded it's unclear if you want the fish or the sushi. I first read it as "what do you call the sushi made from this fish in the picture." Maybe it's just me first thing in the morning, but that's where my mind went to immediately.
I only guessed utah because i had just guessed Uluru (with a "U") and my brain thought that utah was the only state that started with "u". Ten seconds later I realized the coincidence.
Surprised so many got marmalade. I got it, but I just guessed. I don't think very many people in the US eat marmalade, and I couldn't even tell what it was by the picture.
Just to make you sure. Orangutan is brown, more like reddish brown. Not orange. "Orang" means Human in Bahasa, while "Utan" or hutan means Forest/Jungle. So it has name of Orangutan not because it's orange in color.
Either way I like the quiz.
