| @Akhoya: It's really close, my guess is the difference is the handful of people who thought "Ireland" and then dismissed it erroneously as part of the UK.
I went "Iceland" "Ireland" "India" "Illinois" in my thinking so thinking of subnational entities is something that happens.
Having the answers in alphabetical order helped a lot, I don't think I would have gotten them all without being able to narrow down the second letter of the missing countries, and with I- a lot of second-letter combinations are immediately discardable "IO-? IP-? IQ-? IR-? Oh right, Iran/Iraq" |
