Not very hard. I only missed Socatra.. never even heard of that one before. You could have included Cebu, Leyte, or Mactan... good potential clues for each of those.
Cebu: location of the Philippine's 2nd biggest city; Leyte: where MacArthur promised he would return to; Mactan: where Magellan met his end at the hands of Lapu-Lapu.
Or you could include Australia, Tasmania, or New Zealand in the quiz and piss off some people who believe they shouldn't be part of Asia, that's fun, too.
Before this quiz was featured, the percentage of correct answers were mostly around 85-65% with Socotra and Jeju at about 30%. I've heard about Cebu before, of course, but can't say I've heard of Mactan and possibly Leyte... seems familiar. I just didn't want to include another island from South East Asia. Could have put Gan, the largest in the Maldives or Odaiba in Tokyo Bay, or Kavaratti in the Lakshadweep Islands.
/shrug/ up to you. Good quiz anyway. :) I've lived for 5 years on the Arabian peninsula and 3 months on the Korean peninsula- had definitely heard of Jeju before many times. Socotra not so much. Cebu, Mactan, Leyte... I've been to all of those so maybe I'm biased. Though Leyte was in the news a lot lately as the site of the worst devastation from typhoon Haiyan.
Kind of questionable to include Socotra since it's in Africa. Not sure why New Guinea is in the quiz either, especially since the question even acknowledges that it's part of Oceania.
