The other Jetpunk quizzes (eg. http://www.jetpunk.com/quizzes/asian-capitals-quiz.php) spell Sri Lanka's capital as Sri Jayawardenapura Kotte (a, not e). Could you accept that too?
Have added your A version, somewhat reluctantly. Research on Sri Lanka websites shows that E is definitely correct today - however, it appears that A was probably the right spelling prior to Kotte's elevation to capital status.
