I have I few suggestions to make this a good quiz!
First, update the design. This old makes makes people fall asleep.
Then, add actual geography questions. An answer being "Former", even though is related to geography can be replaced for one much better. Same thing with "Village" or "Mount".
Another thing is you're thinking as geography as countries and cities. Try adding other questions about rivers, continents, mountains, ethnic groups, languages, etc.
Finally, even the gramatically correct is "KoreaN peninsula", you should accept "Korea" as an answer.
