You said For “are” in the americas with larger population than Peru but then you said for “are not” IN THE Americas with a population bigger than Colombia so it confused me if they’re in the americas or not!
One other small suggestion: take out the "But still in Americas" in the second half of the population question. It's still a requirement from the first half of the question alone, and restating it distracts from what you're actually asking. Super fun quiz though, I enjoyed playing it. :-)
Technically Brazil is larger than Kazakhstan but not larger than Brazil and the same way San Marino is larger than Monaco and not larger than San Marino. ;)
Please fix the aforementioned Mexico issue and remove the 'But still in the Americas', since that implies it is not in the Americas, given the column header?
Also I think just "Larger than Mexico" would do, that clue you put might confuse people
Also, Germany has more medals than China
"With a larger population than Colombia" is enough and you don't need do add "But still in the Americas" as that just clogs things up
Why doesn't Russia count for that last question? They never played a World Cup final and hosted in 2018.
