1. I see only one

But they're in the Canadian section/arm.

3. I only see Canadian, but American astronauts presumably have the U.S. flag on their spacesuits.

Why does it matter?

4. It was an APOD question.

Someone there posted the question,so I just linked to it.

5. 4 Canadian, 1 Japanese (lower right). I see no US flags.

I'm guessing this "quiz" was posed by a Canadian. :)
